UST Removals in Massachusetts

As of August 7, 2017, MassDEP’s closure requirement 310 CMR 80.15 mandates all single-walled steel underground storage tanks (USTs) to be closed-in-place or removed. Covered under this regulation are tanks and associated piping that have more than ten percent of their volume underground and hold petroleum products or hazardous substances listed in the U.S. Comprehensive Environmental Response Compensation Liability Act. With the deadline now less than one year away, it is important to fully understand single-walled USTs, their potentially harmful impact on the environment, and how to properly plan to remove them.

Single-Walled USTs Explained

USTs have been used for many years to store hazardous substances and petroleum products used by a wide variety of businesses. In addition to the tank itself, a “UST system” includes the underground piping that is used to fill the tank and draw product from it. Until the mid-1980s, most USTs were made of bare steel, which is likely to corrode and leak over time. These leaks can exist undetected for years and cause pollution of the surrounding soil and even groundwater. The piping in the system can also leak if not properly installed and maintained. In many cases, contaminant leaks do not get discovered until the owner or operator realizes that a significant amount of product in a tank goes missing or when the tank is removed and contaminants are found in the underlying soil. Another indication of a leaking UST is neighbors complaining of odors in their buildings or experiencing problems with their drinking water.

Leaking USTs, specifically single-walled steel USTs, have caused considerable environmental damage in Massachusetts, affecting public and private water supplies, wetlands, and soil. In some cases, vapors from contaminated soil and water have permeated homes and businesses. Many millions of dollars have already been spent on cleaning up these leaks, but fully protecting public health and the environment from UST leaks relies on removing or closing the storage tanks altogether.

Benefits of the MassDEP UST Removal Requirements

The removal or permanent closure of aging, single-walled USTs benefits many areas of a community. The new MassDEP regulations will benefit human health, ecosystem functions, and land productivity.

Human health benefits are among the top reasons why single-walled USTs are now required to be removed by August 7, 2017. Contaminated well water and vapor intrusion are the most critical threats to human health from failing USTs. Leaks from USTs can endanger residents for miles through contamination of groundwater, and increased cancer rates and blood disorders have been attributed to exposure to petroleum products, which are commonly found in USTs. The petroleum vapors which are emitted are highly flammable and are potentially dangerous when found in people’s homes. Vapors can travel through soil, sewer lines, storm drainage systems, and other pathways to enter homes and other buildings.

Many single-walled USTs are located in old gas stations, providing the opportunity to add aesthetic and ecological benefits to a community. If a UST leaks into soil, the site becomes contaminated and is considered a brownfield. Removing or closing USTs and making the site usable again decreases the need for development elsewhere and helps preserve greenfields, such as pastures or forests. Many old gas stations are situated in quite visible locations within towns or neighborhoods and can be reused for purposes such as gateways, town centers, or pocket parks. Such redevelopment opportunities improve a locality’s appeal and create recreational value.

Removing or closing-in-place single-walled USTs results in several ecological benefits. Preventing leakage of hazardous material can reduce surface water contamination – protecting fish and other wildlife. Below the ground, removing USTs ensures that leaking tanks will not compromise underground aquifers for future generations. In the long run, this will better protect our drinking water’s taste and purity. Removing USTs also greatly improves land use because former UST sites with a “clean bill of health” will be more likely to develop and prosper without environmental restrictions.

Are there any exceptions to the new regulations?

The MassDEP has included exceptions to the UST removal regulations. Tanks are not required to be removed or closed-in-place if they are consumptive use tanks – such as for heating oil in homes – and single-walled tanks that were relined prior to August 8, 2007 in accordance with API 1631. For these relined tanks to be exempt, the owner or operator must possess a permit and approval issued by the head of the local fire department, or a current legally valid warranty for relining. Other exceptions to the new regulations include single-walled steel tanks that have been wrapped with fiberglass, aramid, carbon fiber, or plastic compounds. It is important to note that single-walled steel tanks that are temporarily out-of-service are NOT exempt from the closure requirement, even if they are consumptive tanks for onsite usage. USTs that are not actively used or temporarily out of service are considered abandoned and must be removed or closed-in-place by August 7, 2017.

MassDEP’s UST closure regulation allows tanks to be permanently closed-in-place only if they cannot be removed from the ground without removing a building, or the removal would endanger the structural integrity of another UST, structure, underground piping, or underground utilities. When closing a tank in place, it is required to clean all contaminants out of the tank to prevent future leaks.

In Conclusion

Meeting MassDEP’s closure requirements means more than just being up to code. Removing hazardous USTs benefits everyone involved. It improves a property’s environmental footprint, removes high risk conditions, and reduces an owner’s environmental liability. Compared to the cost of cleaning up hazardous materials after a UST leak, removing a single-walled UST is well worth it. There is only one year left to comply with the MassDEP UST regulations, so it is imperative to start planning now to remove or close-in-place your single-walled USTs.

Please feel free to contact us for any questions on MassDEP’s requirement or for assistance with UST removals and closures.

International Beer Day: Celebrating Water Efficient Breweries, Take 2

In honor of International Beer Day, we are taking a look at what breweries are doing to conserve the number one ingredient in brewing beer: water. Due to water shortages, increased demand, and heightened awareness, many breweries have taken steps to increase water efficiency and to implement water saving techniques in their brewing. Utilizing a myriad of methodologies and technologies, an increasing number of today’s breweries have begun to focus on brewing beer with water efficiency and conservation at the forefront of their business.

Anheuser-Busch InBev

The undisputed behemoth of the beer world with 25% of the global beer market, Anheuser-Busch InBev has implemented water-saving measures in many ways. Some of its plants use reclaimed water for equipment cleaning, irrigation, firefighting, and other local uses, such as watering a soccer field in Peru and manufacturing bricks in Brazil. And, as would be expected from such an enormous, influential company, Anheuser-Busch InBev is piloting agricultural programs that it hopes will spread to all facets of agriculture. To start, they have initiated a “Smart Barley” program with 2,000 barley growers in Idaho and Montana. Since agriculture accounts for 95% of the water used in beer making, increasing agricultural water efficiency is the key to breweries becoming better water stewards. Utilizing sensors in the field, cooperative programs, and its own hybridized, drought-resistant seeds, Anheuser-Busch InBev hopes to decrease agricultural water usage by 25% over the next two years.

Even before the implementation of its agricultural program, Anheuser-Busch InBev had managed to reduce its water footprint to the point that it now uses less water than any other major brewer. As of this writing, the company uses about 3.2 bottles of water for each bottle of beer, and the industry average is seven bottles of water per each bottle of beer. In fact, from 2013-2014, Anheuser-Busch InBev saved as much water as is used in the manufacture of four billion cans of Budweiser.

MillerCoors

Barley requires 237 gallons of water per every pound grown

MillerCoors is also a giant in the beer industry with 30% of the American beer market. Like its major competitor Anheuser-Busch InBev, it also has an Idaho-based pilot project called the Showcase Barley Farm in Silver Creek Valley, Idaho. Utilizing precise irrigation techniques and hardier crop planting, MillerCoors is researching the best ways to increase its water efficiency. Already a success in 2011, Showcase Farms saw a 9% reduction in water usage by precision irrigation alone.

MillerCoors has also implemented water efficiency and conservation measures at its breweries such as utilizing recirculated water rather than freshwater for cooling, reusing wastewater for non-potable uses, cleaning cans with ionized air rather than water, sanitizing systems with bleach instead of hot water, and installing waterless lubrications throughout their operations. The water reclamation system in their Milwaukee brewery alone saves 100 million gallons of water per year. The company uses 3.53 bottles of water for each bottle of beer it produces — just a tad more than Anheuser-Busch InBev — but it hopes to slash its water footprint an additional 15% by 2020.

Both Anheuser-Busch InBev and MillerCoors have made huge strides towards water efficiency, and because of their massive size, the impact is significant. However, many smaller craft breweries are doing just as much — and in many instances, more — to become water and environmental stewards.

Full Sail Brewing Company

Oregon-based Full Sail Brewing Company is fully committed to water conservation. They operate a hot water recovery system that saves over three million gallons of water per year. Employees work four ten-hour days, which saves another three million gallons of water per year. They have installed special filters to maximize malt extract while minimizing water usage, they’ve reduced spray nozzle apertures on bottle and keg washers, and they’ve reduced cooling water usage by adding a glycol chiller in tandem with their heat exchanger. These measures save an additional 4.1 million gallons per year. The result? The forward thinking company uses just 2.5 bottles of water for each bottle of beer produced — the lowest ratio we have found. But they don’t stop there. Full Sail Brewing operates its own voluntary wastewater treatment plant, which reduces the load to the municipal treatment plant by pre-treating the wastewater. In addition, they distribute their treatment plant’s biosolids to local farmers and an orchardist for fertilizer.

Cape Cod Beer

Hyannis, Massachusetts-based Cape Cod Beer utilizes water reclamation and conservation efforts in their brewing, but they take it a step further. Their beers are only sold in refillable kegs or growlers, and they are passionate about recycling. In addition, they donate all used and leftover grain to local farmers for feed or compost, and they were recently certified “Cape & Islands Green” Level 1.

California Brewers

Bear Republic Brewing Company, whose corporate office and larger brew house are located in Cloverdale, California, actually partnered with the City of Cloverdale to dig two new water wells, which went online last August. Because the City didn’t have the funds for the new wells, Bear Republic prepaid several years of its water fees — $466,000 — in order to allow the city to complete the project on time and under budget. Bear Republic also conducts regular audits for leaks, practices conservation and reclamation in its operations, and is installing a wastewater pre-treatment plant that will generate heat and electricity with the methane it produces as well as reclaimed water for irrigation and cleaning.

In Escondido, California, the nation’s tenth largest craft brewer, Stone Brewing Company, treats all of their brewing wastewater — not to be confused with restaurant or restroom wastewater — with an aerobic digestion and filtration process. The reused water is pure and they use it for cleaning. “From a good brewing practices standpoint, it’s good to watch water usage, especially when you live in a dry area like we do,” explained Mitch Steele, Stone’s Brew master. He also added that they test the reclaimed water frequently and that, if regulations allowed, he wouldn’t hesitate to drink it.

Adding to their already environmentally friendly business practices, both Stone Brewing and Bear Republic have been proactive in sharing their practices and knowledge with the rest of the craft beer community through webinars and on-site tours.

Brewers for Clean Water

So far, over 50 craft breweries, including eight New England breweries, have joined the National Resource Defense Council’s Brewers for Clean Water initiative. The program aims to spread awareness of the Clean Water Act and to support initiatives that protect and conserve our nation’s water. “As we continue to see the craft beer segment grow, we as brewers owe it to the communities we live, work, and play in to be mindful of protecting our waterways as we strive for growth that is environmentally and socially responsible now and down the road,” said Mat Stronger of Allagash Brewing Company, a Portland, Maine-based brewery that is active in the Brewers for Clean Water initiative.

Jester King Brewing with Harvested Rainwater

Jester King's rainwater collection tanks — Jester King’s rainwater collection tanks

Austin, Texas-based Jester King Brewery recently purchased 3,000-gallon rain water collection tanks that will collect rainwater from the roof of both their brewery and adjacent beer hall. They expect to capture an estimated 10,000 barrels of rainwater per year that will be disinfected using ultraviolet and reverse osmosis purification and then be used in their brewing process.

Beer Made with 100% Reclaimed Water

Clean Water Services, a wastewater treatment utility that serves the Portland, Oregon metro area, asked for approval from the state to allow members of the “Oregon Brew Crew” to use recycled sewage water from its Forest Grove plant for beer-making. They received initial approval from the Oregon Environmental Quality Commission and the Oregon Health Authority, but will need further approval for a recycled water reuse plan before forging ahead. Last year, the Oregon Brew Crew produced test batches of beer made from 30% reclaimed water, which met with rave reviews. But, according to the dozen brewers, using 100% reclaimed water will be a more exciting challenge.

“I’m trying to think of a really cool recipe. When they told us 100 percent we’re like oh man, first the names, then the recipe comes later. And I’m excited,” said Lee Hedgmon, president of the Oregon Brew Crew.

Clean Water Services believes that educating the public about recycled water will lead to its ultimate acceptance, and they don’t think there’s any better way to start that conversation than with beer.

Sewage Beer

Really. It’s called Activated Sludge, has a radiation symbol on its label, and is brewed with purified Milwaukee Metropolitan Sewerage District wastewater plant effluent that has NOT gone through the final cleaning process typically necessary for potable reclaimed water.

Theera Ratarasarn, a wastewater engineer with the Wisconsin Department of Natural Resources, enjoys home-brewing beer to relax after his two young sons have gone to bed. After doing some thinking, he decided he wanted to raise awareness of the quality of plant effluent, and figured the best way to do so was with his evening hobby.

“I wanted to get people talking,” he said “There’s a potential use for what we discharge into lakes and streams.”

Ratarasarn filtered, treated, distilled, and tested the water before beginning to make five gallons of his Activated Sludge, a wheat ale with 5.15% alcohol by volume. And then came the true test. Ratarasarn presented his sewage brew to a taste panel at Lakefront Brewery, where Activated Sludge competed against Lakefront Wheat Monkey. The result? “It’s one of the better home brews I’ve ever had,” stated Mitchel De Santis, who graded the beer a seven out of ten.

“Everybody I talk to wants one,” added Ratarasarn.

Brewing Up Water Efficiency

Breweries are some of the largest consumers of water, yet have proven that they are some of the most active conservationists. We’ve heard it before: everyone loves beer, so it is an easy way to spread awareness, start conversation, and implement efficiency and conservation techniques. While we may not be drinking sewage beer any time soon, we can all agree that U.S. breweries are doing their part in the water conservation effort — and that’s something to which we can raise a toast. Happy International Beer Day!

The Real Cost of Non-Revenue Water and How a Water Audit Can Help

Physical losses such as leaking or broken water mains are known as real losses. There are about 240,000 water main breaks per year in the US.

Every day, United States utilities lose around seven billion gallons of clean, treated drinking water. This “lost” water, referred to as non-revenue water (NRW), is caused by a number of factors, including leaking pipes, water main breaks, theft, and improper accounting of water. In fact, we lose enough water each year to supply our ten largest cities. Of the estimated $200 billion needed over the next 20 years to upgrade our water distribution systems, $97 billion is needed for water loss control. With water crises occurring throughout the country, NRW is a big deal.

How NRW Affects You

Non-revenue water affects everyone in a water distribution system. Although it is considered “non-revenue” water, many utilities include these costs in their rates, which is reflected in your bill. The less NRW a water utility produces, the lower its total costs will be. And let’s face it: no one wants to pay for things they don’t use. Also, a lower percentage of NRW reflects positively on your local water utility’s performance. Utilities with low NRW percentages typically perform well at replacing broken water mains and meters, and defending against theft.

Metering errors, theft, and billing errors result in water "appearing" to be lost. These non-physical losses are called apparent losses. — Metering errors, theft, and billing errors result in water “appearing” to be lost. These non-physical losses are called apparent losses.

When water leaks from pipes, it can erode the subsurface underneath roads and other public
infrastructure. When the erosion reaches a critical point, the road collapses or a building’s foundation can fail. The better your water utility performs in NRW reduction, the less likely your community will need to replace its public infrastructure, especially roads. Our population is continuously growing and without improved efficiency, water supply expansion and treatment projects will be necessary — significantly increasing the cost of water. Improving water use efficiency by reducing NRW defers the expense of water supply expansion and treatment. If we can prevent clean, treated water from getting “lost,” there will be less of a need to find new sources or increase capacity.

Leaking pipes contributing to non-revenue water also can pose a health risk to communities. Contaminated groundwater from leaking sewage or pollution can find its way into drinking water pipes during low pressure events. Contaminated drinking water then has the potential to spread disease and other harmful substances.

Water Audits and NRW

The best way to reduce a utility’s NRW is through routine water audits. Most utilities in the U.S. conduct infrequent water audits and, therefore, are likely suffering substantial losses without even being aware of it. Since 2005, a number of state and regional water resource agencies in the United States have established water audit reporting requirements for water utilities. In addition, the American Water Works Association (AWWA) has developed and published a methodology for identifying and controlling NRW, M36 Water Audits and Loss Control Programs, now in its fourth edition. Tata & Howard Vice President Steve Rupar, P.E. co-authored chapters 4 and 5 of the new M36 manual, which focus on the causes of apparent loss and what can be done to control it. An expert in water loss control, Steve has also given presentations and a webinar on the subject, which can be found here. Water audits help utilities identify the causes and costs associated with water loss, and develop strategies to avoid NRW. They also help to identify areas of a distribution system requiring repairs or maintenance. Water audits are important, especially in the northeast, where some infrastructure is over 100 years old. Preventing NRW helps save our infrastructure, our money, and most importantly, our water.

In Conclusion

NRW affects everyone, and it’s important to monitor and continuously improve water distribution systems. Water audits are a vital step toward reducing lost water while improving water infrastructure. We lose billions of dollars every year to NRW — money that could be used to improve our infrastructure or to support other clean water initiatives. Water lost is water and money wasted, and the less NRW a utility has, the better off it — and its customers — will be.

Water Crisis in the United States, Part 4: Colonias

Recently in the news, we have heard a lot about the nationwide lead in drinking water crisis and the need to update our aging infrastructure. In addition, the plight of the people living in Navajo Nation has been brought to the nation’s attention after being showcased in a video by CBS Sunday Morning News. However, there is yet another very serious water crisis in the United States that has garnered very little media attention, and this week, we will be concluding our four-part series on water crises in the United States by talking about colonias.

What Are Colonias?

Colonia translates to neighborhood in Spanish, and in the United States, colonias are primarily Hispanic neighborhoods found along the Mexican border in Arizona, California, New Mexico, and Texas. With over 2,200 colonias, Texas has by far the most colonias in the nation, as well as the largest colonia population with over 500,000 residents. The modern-day colonia population is about 96% Mexican-American, with about 74% of those — and 94% of colonia children — being American citizens.

colonias_texas_Proyecto-Azteca-300x189 — A Texas colonia residence

Colonias originated in the 1950s. At this time, less than honorable developers bought up worthless land along the Mexican border — such as land that was agriculturally useless or located in flood plains — parceled it into tiny lots with little to no infrastructure and sold it off to low-income immigrants in search of affordable housing. To this day, colonias are often bought through a contract for deed, which is a questionable financing method by which developers offer low down and monthly payments with a very high interest rate and no title until the loan is paid in full. Prior to 1995, developers did not typically record the transactions with the county clerk, leaving the buyer with virtually no rights. If they fell behind on payments, the developer could repossess the property quickly, usually within just 45 days, without going through the foreclosure process.

Fortunately, Texas passed the Colonias Fair Land Sales Act in 1995 to somewhat protect colonia residents who are forced to finance through a contract for deed. The Act requires developers to record the contract with the county clerk and to provide property owners with an annual statement that shows the amount paid towards the loan and taxes as well as the number of remaining payments. The Act also forces developers to itemize which services, such as water, wastewater, and electricity, are available, and whether the land is located in a flood plain.

While the Colonias Fair Land and Sales Act has improved contract for deed sales, there remain serious problems. Because property owners do not actually own the land or have a title, they cannot secure any type of financing that uses the property as collateral. Considering that colonia residents are typically well below the poverty level, any other types of financing are also unavailable to them, making it impossible to improve their property. Therefore, colonia residents typically construct their homes in drawn out phases as funds become available to them. Because of this, colonia homes often do not have electricity or even basic plumbing.

Challenges in Colonias

Arguably the most serious challenge facing colonias is the lack of improved water and sanitation services. Many colonias do not have public sewer systems and instead rely on rudimentary septic systems or outhouses that are often inadequate and overflow. And because the land is frequently in flood plains with poorly constructed roads that do not properly drain, sewage collects and pools, rife with bacteria and pathogens. Even colonias that do have sewer systems typically lack any type of wastewater treatment. Therefore, untreated wastewater is discharged into local streams that flow directly into the Rio Grande or the Gulf of Mexico.

Potable water also presents a challenge to colonia residents. Very often, inhabitants must buy water in drums to meet their needs, or, even worse, they utilize untreated water from wells that are contaminated. Some private companies have installed water “vending machines” that provide bottled water at an astronomical cost to residents who can ill afford it. Even colonias that do have water lines have major problems, because residents are unable to tie-in due to their homes not meeting county building codes; to meet the building codes, they need to have adequate plumbing — a true Catch-22 situation. In fact, housing in colonias is typically considered dilapidated by local inspectors. Residents often start with just tents, cardboard, and lean-tos, and make improvements little by little as funds allow.

Due to the lack of improved water and sanitation, as well as lack of electrical services, it should come as little surprise that health conditions in colonias are often deplorable. Hepatitis A, dysentery, tuberculosis, cholera, salmonella, and other diseases occur at an astronomically higher rate in colonias than they do in the rest of Texas, according to Texas Department of Health data. To make matters worse, most colonias do not have local medical services and have a serious shortage of primary care providers, and most colonia residents lack health insurance. Therefore, the average age of colonia residents is only 27 — a full 10 years younger than the national average. And, just as is the case in Africa and other developing areas, quality of health is directly linked to quality of education. Therefore, many colonia residents remain undereducated — 55% of residents do not have a high school diploma — causing the cycle of poverty to continue generationally. The unemployment rate in colonias is anywhere from 20-60%, compared with 7% for the rest of Texas.

Assistance to Colonias

Thankfully, through a series of public outreach initiatives, more attention has been brought to the existence of colonias and the third-world conditions in them. In the last 20 years, the Texas Secretary of State has been recording the infrastructure, or lack thereof, within colonias and providing a significant amount of funding — tens of millions of dollars — to improve these areas. And it is working, albeit slowly. Since 2006, about 100 colonias have been moved out of the “red” category, indicating the worst conditions. However, with over 2,200 colonias along the Texas-Mexico border, there is still much work to be done.

On a federal level, USDA Rural Development has grants available through the Individual Water and Wastewater Program for households residing in an area recognized as a colonia before October 1, 1989. The colonia must be located in a rural area and determined to be a colonia on the basis of objective criteria including lack of potable water supply, lack of adequate sewage systems, lack of decent, safe and sanitary housing, and inadequate roads and drainage. Grant funds may be used to connect service lines to a residence, pay utility hook-up fees, install plumbing and related fixtures like a bathroom sink, bathtub or shower, commode, kitchen sink, water heater, outside spigot, or bathroom, if lacking. Qualifying applicants must own and occupy their home, show income from all individuals residing in the home below the most recent poverty income guidelines, and not be delinquent on any Federal debt. The maximum individual grant for water systems is $3,500 and for wastewater is $4,000 with a lifetime assistance maximum not to exceed $5,000 per individual. Further information can be found on USDA’s web site. In addition, the United States Department of Housing and Urban Development (HUD) in Texas, Arizona, California, and New Mexico has set aside up to 10 percent of their State Community Development Block Grant Program (CDBG) funds for improving living conditions for colonias residents.

Fortunately, colonia residents are a very resourceful, tight knit group who are willing to work together and help each other, and some private and non-profit institutions have also become involved in the plight of colonia residents. For example, Texas A&M worked with residents on a water filtration project which involved making simple filters to make water potable. In addition, a non-profit lender called the LiftFund has provided loans to some colonia residents to assist them with starting a business. These loans have a very low interest rate and are given to people who cannot qualify for a traditional loan. Colonia residents are very often entrepreneurial in spirit, perhaps through necessity. After all, for years they have done what they need to do to get by, whether it be selling handmade crafts at flea markets or cutting up tires dumped along colonia roads and turning them into unique flower pots.

In Conclusion

Colonias are a little known part of America that have conditions oftentimes no better than those found in developing countries. One of the biggest causes of generational poverty in colonias is attributed to lack of basic water and sanitation services, causing health and education issues. Just like the plight of the people living in Navajo Nation, it is shameful that people living in the richest land in the world do not have access to these basic human rights. Add to this the lack of charitable organizations supporting water poverty in the United States, and colonias qualify as one of the most significant, and heartbreaking, water crises in the nation.

Water Crisis in the United States, Part 3: Lead in Drinking Water

Part three of our four-part series on water crises in America is on lead contamination. Instances of lead in drinking water, such as the situation in Flint, Michigan, have become a hot topic in the media. Lead in drinking water is a problem that reaches far beyond the disaster in Flint, with the Environmental Protection Agency (EPA) stating that roughly 10 million American homes and buildings still receive water from service lines that are at least partially lead. When water has high acidity or low mineral content, it can cause these service lines to corrode and leach lead into the water supply. Without mitigation, water from lead service lines has the potential to cause adverse health effects, particularly in children.

The EPA states that, in the last three years, only nine U.S. states are reporting safe levels of lead in their drinking water. These include Alabama, Arkansas, Hawaii, Kentucky, Mississippi, Nevada, North Dakota, South Dakota, and Tennessee. This means that 41 states are consistently reporting higher than acceptable levels of lead in their drinking water. The problem is not only the lead service lines connecting water mains to homes and buildings, but also the lack of proper treatment to prevent corrosion of these lead pipes.

History of Lead Pipes in the U.S.

Residents of Flint, Lead solder holding pipes together can also contaminate the water that passes through your system. — Lead solder holding pipes together can also contaminate the water that passes through your system.

The use of lead pipes for water distribution has a centuries-old history. In the U.S., installation of lead pipes on a major scale began in the late 1800s, particularly in the larger cities. At one point, more than 70% of cities with populations greater than 30,000 used lead water lines. Lead pipes had two significant advantages over iron: they lasted almost twice as long and they were malleable enough to easily bend around existing structures. Of course, now we see the health risks associated with lead, and water systems across the country have taken steps to eliminate lead pipes in their distribution systems. Water companies and municipalities now must decide whether to replace all the lead pipe in their drinking water system, including home service lines on private property, or continue to add corrosion-control chemicals at the plant to prevent leaching of lead into the water supply.

Utilities and the Government Take Action

Water companies and municipalities across the country are working diligently to get lead out of our drinking water. Since replacing all of our nation’s lead piping may take over 20 years, utilities have found a short term solution to control the amount of lead in their drinking water. They are focusing on the treatment process and monitoring what makes up the drinking water. Introducing orthophosphates to the water supply and flushing all the standing water creates a scale of protective coating on the interior surfaces of lead pipes, reducing corrosion. This limits the amount of lead that leaches into the water and offers a short term solution as we figure out how to permanently replace all lead pipes from our water distribution systems.

Limescale-in-pipe-300x259 — Orthophosphates added to treated drinking water has created a protective coating on the interior surface of this lead pipe.

In Wisconsin, the Madison Water Utility has become a national model for cities struggling with lead in their drinking water. They are the first major utility in the nation to demonstrate that a full replacement of both the public and the private portions of lead service lines is possible. This involved working with residents to remove lead service lines from their homes and nearby property. The project started in 2001 and has provided safe drinking water to 5,600 property owners. The plan, which was very controversial at the time, is now hailed as a model and has spurred other utilities into action. For example, Boston Water and Sewer Commission (BWSC) implemented a program that offers a credit of up to $2,000 and interest-free loans to assist homeowners who are willing to remove lead pipes on their property. BWSC also has a searchable online database for homeowners to see if their property has a lead service line. Also, the Massachusetts Water Resource Authority (MWRA) announced earlier this year that it will provide $100 million to its member water communities to fully replace lead service lines, including residential lines. These utilities are shining examples of the many organizations taking a long term approach to this national crisis.

Recent news reports of lead in drinking water and the controversy surrounding testing methodologies have acted as a catalyst for public schools across the country to test their water. Unfortunately, many of these tests indicate high, potentially dangerous, levels of lead concentrations in public drinking fountains, sparking outcry from parents and prompting a series of public meetings. In response, the EPA changed lead testing regulations on February 29, 2016 and now require utilities to use wide mouth bottles, conduct no pre-stagnation flush, and to run faucets at typical flow rates when testing for lead — precisely the opposite of how testing had previously been conducted. While many people have been quick to blame utilities for lead in their drinking water and have even gone so far to suggest that utilities have been practicing testing “cheats,” they were in actuality following protocol issued by EPA.

The EPA is also considering changes to the Safe Drinking Water Act’s rules regarding lead, and an advisory panel has proposed a more proactive approach to replacing lead pipes. The proposal would encourage public water systems to replace lead pipes versus waiting for lead levels to spike to take action. This plan involves substantial increases in funding to water companies and municipalities for the replacement of lead pipes in both the public and the private portions of lead service lines, including residential lines. With this additional funding, water utilities across the country will be able to set goals for a permanent solution to our nation’s lead crisis. Admittedly, we have a long road ahead of us as many cities simply do not know the exact number or location of lead pipes in their system. Add to that the cost and person power required to replace our nation’s lead service lines, and it becomes apparent that a 100% lead-free infrastructure is still many years away.

What Can You Do?

When water sits stagnant in lead service lines for even a few hours, it picks up lead from the pipe, which can make using your faucet hazardous. Find out if your home is serviced by lead service lines by calling your local water department. This is especially important to homes built prior to 1980. If your home still has lead service lines, you can reduce the risk of lead contamination in your drinking water by taking some simple steps:

Call your State Department of Public Health for health information, or visit their website.
Run tap water until after the water feels cold. Flushing pipes in this way before use assures that you are not drinking water that has been sitting stagnant in pipes.
Never use hot water from the faucet for drinking or cooking, especially when making baby formula or food for small children. Hot water from your faucet has a higher chance of containing traces of lead. Instead, use cold water and heat it on the stove or in the microwave.

In Conclusion

The good news is that lead contaminated water crises like the situation in Flint, Michigan have called for stricter regulations and replacement of nearly six million lead service lines nationwide. The not so good news is that we still have a long way to go to completely remove all lead in our water systems. Nearly all homes built prior to the 1980s still have lead solder connecting copper pipes, and some major U.S. cities still have 100 percent lead piping that delivers water from the utilities to homes and businesses. Replacing lead service lines is the safest way to prevent lead contamination, and public and private water companies must work together with state and national organizations to replace lead pipes in all of our water distribution systems. Solving our lead contamination crisis will benefit everyone if we work together for a permanent solution. After all, everyone deserves safe drinking water.

Ribbon Cutting Ceremony for New Water Storage Tank in New Britain, CT

Elam Street water storage tank ribbon cutting ceremony in New Britain, Connecticut was held on June 17, 2016

On Friday, June 17, 2016, New Britain Mayor Erin E. Stewart hosted a ribbon cutting ceremony to mark the completion of the construction of the new Elam Street water storage tank. In addition to Mayor Stewart, other attendees included Director of Utilities Gilbert Bligh, Raul Tejada from the Connecticut Department of Public Health, and Tata & Howard Vice President Steve Rupar, P.E.

Tata & Howard provided design, bidding, construction administration, and resident observation services for this important New Britain Water Department Project. The new 2.0 million gallon, precast, prestressed, wire-wound, concrete water storage tank replaces an existing deteriorated 4 million gallon water storage tank constructed in 1956. The project also included construction of approximately 450 linear feet of new 16-inch diameter water main, mechanically cleaning and cement mortar lining approximately 430 linear feet of 20-inch diameter main, upgrades to the Corbin Avenue Pump Station and West Main Street Gatehouse, and demolition of much of the existing water storage tank. The lower portion of the existing water storage tank was repurposed as a drainage and overflow retention basin for the new storage tank. Construction of the $3.3 million project was funded through the Drinking Water Revolving Fund, administered by the Department of Public Health.

MS4 Compliance Assessments — Act Now for FY18 Budgeting

In April, EPA issued the revised General Permit for Small Municipal Separate Storm Sewer Systems (MS4s) in Massachusetts. The permit becomes effective July 1, 2017, so it is crucial to start preparing now.

Tata & Howard’s MS4 Compliance Assessments help municipalities determine how they already comply with the new requirements, what else must be completed to comply, and how much it will cost. The assessment also provides a well-planned course of action that is defendable when justifying projects and procuring funding. Complete your assessment now and be prepared for your FY18 budget.

We are currently scheduling MS4 Compliance Assessments to ensure municipalities have sufficient time to submit FY18 budgetary requests. Contact our Stormwater Project Manager Jon Gregory, P.E. for more information or to request an assessment.

Tata & Howard has extensive experience assisting Massachusetts municipalities and coalitions with MS4 compliance. Learn more:
