Dear Customer,
I am happy to provide you with the results of our annual drinking water testing for 2021. Once again, every federal and state standard was met and the quality of your drinking water is excellent.
I also want to assure you that we are constantly checking your water. We have a state-of-the-art monitoring system from the treatment plant to your local pipes, and we take hundreds of thousands of tests each year to ensure that your water is safe. We are also closely watching other important issues that could affect our water, from climate change to cybersecurity. You can be sure that the safety of your drinking water is the top priority for the women and men of the MWRA.
We continue to take aggressive actions to reduce the risk of lead in drinking water. Since 2016, we have provided $30 million in zero-interest loans to 13 communities for full lead service line removals. System-wide, we remain below the Lead Action Level. Please read your community’s letter for more information on your local water system.
PFAS - or ‘forever chemicals’ – remain a top news story. Since our source water is so well protected, our water easily meets the Massachusetts Department of Environmental Protection’s standards.
Last year, we welcomed two new communities to our water system: Ashland and Burlington. Our reservoirs have ample supplies to meet the needs of our service area; but, it is important that we all conserve water wherever possible. This is our most precious resource and we cannot afford to waste it.
I hope you will take a moment to read this report. We have great confidence in the water we deliver to your homes and businesses, and we want you to as well. Please contact us if you have any questions or comments about your water quality, or any of MWRA’s programs.
Sincerely,
Frederick A. Laskey
Executive Director

At the Water Source…
From the Watersheds to Your Community
MWRA supplies about 7 million gallons of high quality water each day to the three Chicopee Valley Aqueduct (CVA) communities: Chicopee, Wilbraham, and the South Hadley Fire District#1 (FD#1). MWRA works with your community, the Department of Conservation and Recreation (DCR), and state and federal regulators to continuously monitor your drinking water - from the reservoirs surrounded by forests and wetlands, through treatment and miles of pipelines, to your drinking water faucet.
MWRA’s work to protect the drinking water at your home or business starts at the Quabbin Reservoir. The Quabbin is the primary source for all the water supplied to the CVA communities. The Ware River provides additional water.
The Quabbin watershed — the area that drains water to the reservoir — is naturally protected, and is an important first step in providing you high quality water. More than 85% of the watershed is covered with forests and wetlands, which filter the rain and snow that enter the streams that flow to the reservoir. This water comes in contact with soil, rock, plants, and other material as it follows its natural path to the reservoir. This process helps to clean the water, but it also can dissolve and carry very small amounts of material into the reservoir. Minerals and rock do not typically cause problems in the water. Water can also transport contaminants, including bacteria, viruses or other potential pathogens, from human and animal activity, that can cause illness. Testing results show few contaminants are found in the reservoir water. The few that are detected are in very small amounts that are well below EPA’s standards.
MWRA and DCR maintain a nationally recognized watershed protection program. The Department of Environmental Protection’s (DEP) Source Water Assessment report for the Quabbin and Wachusett Reservoirs commended DCR and MWRA for our source water protection plans. The report states that our “watershed protection programs are very successful and greatly reduce the actual risk of contamination.” MWRA and DCR follow the report recommendations to maintain the pristine watershed areas. For more information on our source water, visit our Water-Shed Protection page.
Testing to the Tap
MWRA analyzes, treats and protects the quality of your water from its source to your home or business, starting with the watershed streams, to hundreds of miles of MWRA pipes and thousands of miles of local pipes, all the way to your home. MWRA testing shows that few contaminants are found in the water from our reservoirs. All were well below EPA’s standards in 2021.
A key, initial test for reservoir water quality is turbidity, or cloudiness. Turbidity refers to the amount of suspended particles in the water and can impair water disinfection. All water must be below 5 NTU (nephelometric turbidity units), and water can only be above 1 NTU if it does not interfere with effective disinfection. In 2021, typical levels in the Wachusett Reservoir were 0.29 NTU, with the highest level of turbidity at 0.61 NTU, well below the standard.
MWRA also tests water for potential disease-causing organisms, including fecal coliform bacteria, and parasites such as Giardia and Cryptosporidium, that can enter the water from animal or human waste. All test results for the reservoir water were well within state and federal testing and treatment standards.

Monitoring Water, Start to Finish
MWRA analyzes, treats and protects the quality of your water from its source in the Quabbin Reservoir to your home or business. MWRA’s laboratories conduct hundreds of thousands of tests on the water your community receives from MWRA every year, for over 120 potential contaminants. All results were well below EPA’s standards in 2021.
During Treatment
Downstream of the reservoir, MWRA’s Brutsch Water Treatment Facility provides state of the art treatment and monitoring of your water. Well trained and licensed operators add measured doses of treatment chemicals to improve the quality of your
Conservation, Climate Change, and Your Reservoirs
MWRA works with the communities we serve to promote water conservation. Efficient and wise use of our water keeps it available for the future. We monitor stream flow, reservoir levels and climate forecasts to ensure reliable supply under all conditions, including droughts and major storms. The engineers and planners who designed our supply left us a robust, reliable, system for the future.
MWRA water use has dropped by over a third since the 1980s. It's up to all of us to continue to use water wisely. Every drop counts. our web site has many tips on how to save water indoors and outside.
water. Additional water treatment includes:
- Ultraviolet light (UV), a natural, but more powerful form of natural disinfection than sunlight, renders pathogens non-infectious.
- Chrlorine protects the water as it travels through miles of pipelines to your home.
- Each community treats the water to reduce the leaching of lead from home plumbing.
- Chicopee performs additional booster disinfection at the point where the local pipes take water from the MWRA aqueduct.
Evaluating Local Water Systems
Water conditions can change within your town’s distribution system. Each community tests for contaminants that can vary within community pipes. MWRA also works with the three CVA communities to test water samples in local piping each week for total coliform and E. coli bacteria. Total coliform bacteria can come from the intestines of warm-blooded animals, or can also be found in soil, plants or other places. Most of the time these bacteria are not harmful; however, their presence in water can indicate that harmful bacteria from fecal waste may be there as well. If total coliform is detected in more than 5% of samples in a month, the water system is required to investigate the possible source and fix any identified problems. If a water sample does test positive, we run more specific tests for E. coli, which is a bacteria found in human and animal fecal waste and may cause illness. No E. coli was found in any CVA community water in 2021.
Information on PFAS Testing
PFAS, or per- and polyfluoralkyl substances, have been used since the 1950s for many products — stains, water proofing, firefighting equipment and other applications. These chemicals are an environmental concern, and have been linked to significant health risks.
In 2020, the MassDEP published a drinking water standard for PFAS based on six PFAS compounds, or PFAS6. Tests of MWRA water in our reservoirs showed only trace amounts of these compounds, well below the new State maximum contaminant level (MCL) of 20 parts per trillion. For more information on PFAS, go to: www.mwra.com.

The Facts on Lead in Drinking Water
Preventing lead exposure is particularly important if a pregnant woman or a child lives in your home or apartment. Lead can also impact the health of your entire family. While lead poisoning frequently comes from exposure to lead paint dust or chips, lead in drinking water can also contribute to chronic, total lead exposure. Learn about the health impacts of lead, and how to reduce exposure to this toxic metal that could be in your drinking water, on the following pages.
How Lead Can Enter Your Water
Lead can enter your tap water from your service line (the line that connects your home to the water main) if it is made of lead, lead solder used in plumbing, or from some older faucets.
Lead in your home plumbing or service line can contribute to elevated lead levels in the water you drink. MWRA’s water is lead-free when it leaves our reservoirs. Distribution pipes that carry the water to your community are made mostly of iron and steel, and do not add lead to the water.
Corrosion, or wearing away of lead-based materials can add lead to tap water, especially if water sits for a long time in the pipes before it is used. Each CVA community adjusts the water chemistry to reduce corrosion. See what your community does to reduce corrosion in the Community Updates section and the results in the table below.
Important Lead Information From EPA
If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water comes primarily from materials and components associated with service lines and home plumbing. MWRA is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. If your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 1-800-426-4791 or www.epa.gov/safewater/lead.
What is An Action Level?
An Action Level is the amount of lead that requires action to reduce exposure. If your home or school’s drinking water is above the lead Action Level, additional steps to reduce lead may be required. If more than 10% of your community’s samples were over the lead Action Level, your local water department is taking action to address the problem.
CVA Communities Meet Lead Standard
Under EPA and DEP rules, your local water department is required to test tap water in homes likely to be at risk for high lead levels, such as homes with lead solder. The EPA Lead and Copper rule requires that 9 out of 10 homes tested must have lead levels below the Action Level of 15 parts per billion (ppb). This testing process can provide information on whether lead is corroding and mixing with the drinking water. The results do not reflect lead levels in every home. All three of the CVA communities meet the lead Action Level.
How Lead Affects Health and Development
Lead affects young children, and may cause damage to the brain, slow growth and development, and learning and behavior problems. Preventing lead exposure is particularly important if a pregnant woman or a child lives in your home or apartment. Lead can also impact the health of your entire family. While lead poisoning frequently comes from exposure to lead paint dust or chips, lead in drinking water can also contribute to chronic, total lead exposure.

Lead Service Lines
A service line connects your home or building to the water main in the street. If yours is made of lead, it can be the main source of lead in your tap water. Older pipes that combined galvanized iron and lead connectors (“goosenecks”) can also release lead. Lead services lines should be removed entirely to prevent lead in your drinking water.
Your local water department can help find out if you have a lead service line, and provide help in replacing it. In some cases, an onsite check is necessary to determine the specific piping to your building.
You can also see if your service line is made of lead by scratching the pipe near your water meter with a key or other metal object. Lead pipes will show a dull grey color, while copper pipes will not. For an online how-to guide, go to www.epa.gov/pyt.
MWRA Funding to Replace Lead Service Lines
MWRA and its Advisory Board offer zero-interest loans to customer communities for full lead service line replacement projects. Each MWRA community can develop its own local plan, and many communities have already taken steps to remove lead service lines. To find out more, contact your local water department.
3 Ways to Reduce Lead in Your Water
- Remove your lead service line
- Run your water before using
- Use a filter certified to remove lead
Reduce Your Exposure to Lead
Remove Lead Piping
- Find out if you have a lead service line or lead components in your plumbing. Learn about options for removal of this piping from your local water department.
- Any time water has not been used for more than 6 hours, run the faucet used for drinking water or cooking until after the water becomes cold.
- Let water run before using it—fresh water is better than stale. To save water, fill a pitcher with fresh water and place it in the refrigerator for future use.
- Never use hot water from the faucet for drinking or cooking, especially when making baby formula or other food for infants or young children.
- Remove loose lead solder and debris. Every few months, remove the aerator from each faucet and flush the pipes for 3 to 5 minutes.
- Be careful of places where you may find lead in or near your home. Paint, soil, dust and pottery may contain lead. Call the Massachusetts Department of Public Health at 1-800-532-9571 or 1-800-424-LEAD for information on lead and health impacts.
How to Test Your Drinking Water
If you are concerned about lead piping in your home, contact your local water department about testing for lead in your drinking water. MWRA also maintains a list of certified laboratories and sampling instructions on our website at www.mwra.com. You may also call MWRA at 617-242-5323.
Lead Testing in Schools
Children can consume most of their drinking water at school or daycare. The plumbing inside some schools and childcare facilities can contain lead and contribute to lead exposure. MWRA, in coordination with DEP, provides no-cost lab analysis and technical assistance for schools and day care centers in MWRA communities. This service has been offered since 2016, and nearly all MWRA communities have participated. To date, more than 39,000 tests have been completed in more than 530 schools. Results are available on the MassDEP website at: www.mass.gov/dep (search for “lead in schools”). You may also contact your local school or water department for results.
Monitoring All Day, Every Day
MWRA's monitoring systems are in operation continuously, 24/7/365. The systems help us evaluate your water before and after treatment. They also help us determin if the water is free of contaminants, and to respond rapidly to changes or issues related to water quality.
Continuous Testing of Your Water
Important Research for New Regulations
MWRA works with EPA and health research organizations to help define new national drinking water standards by collecting data on water contaminants that are not yet regulated. Very few of these potential contaminants are found in MWRA water due to our source water protection efforts. Information on this testing, as well as data on PFAS, disinfection by-products, Giardia and Cryptosporidium, and other contaminants can be found at www.mwra.com.
Important Health Information: Drinking Water and People with Weakened Immune Systems
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants, can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the EPA’s Safe Drinking Water Hotline (1-800-426-4791).
EPA Information on Bottled Water and Tap Water
Complaints Are Important!
You can help provide information about local water quality. Every call is investigated. Most complaints are related to discolored water (usually related to local construction or hydrant use), or conditions in a building’s plumbing. Contact your local water department, or call MWRA at (617) 242-5323.
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (1-800-426-4791) or MWRA. In order to ensure that tap water is safe to drink, the Massachusetts DEP and the EPA prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. The U.S. Food and Drug Administration (FDA) and the Massachusetts Department of Public Health (MDPH) regulations establish limits for contaminants in bottled water, which must provide the same protection for public health.
Funding for System Rehabilitation
MWRA provides zero-interest loans to communities for pipeline rehabilitation and other water quality improvements. During 2021, we loaned $28 million in loans to 18 communities for pipeline projects and $11 million to 8 communities for lead service line replacements.
Cross-Connection Information
A cross-connection is any temporary or permanent connection between a potable (drinking) water source and a non-potable source. Non-potable water or other sources can contaminate your drinking water if backflow occurs.Massachusetts DEP recommends the installation of backflow prevention devices for inside and outside hose connections to help protect the water in your home as well as the drinking water system in your town. For more information on cross-connections, please call 617-242-5323 or visit www.mwra.com.
MWRA Wins the MassDEP Public Water Systems Award
The Department of Environmental Protection awarded a Public Water System Award to MWRA in 2021, recognizing MWRA's continued excellent level of performance and compliance with all drinking water standards.
