Manganese is a naturally occuring mineral found in rocks, soil, groundwater and surface water. Manganese is necessary for proper nutrition and is part of a healthy diet, but can have undesirable effects on certain sensitive populations at elevated concentrations. The United States Environmental Protection Agency (EPA) and MassDEP have set and aesthetics-based Secondary Contaminant Level (SMCL) for manganese at 50 micrograms per liter (ug/L), or 50 parts per billion (ppb), and health advisory levels. In addition, EPA and MassDEP have also established public health advisory levels.
Drinking water may naturally have manganese and, when concentrations are greather than 50 ug/L, the water may be discolored and tase bad. Over a lifetime, EPA recommends that people drink water with manganese levels less than 300 mg/L an over the short term, EPA recommends that people limit their consumption of water with levels over 1000 ug/L, primarily due to concerns about potential neurological effects. Children up to 1 year of age should not be given water with manganese concentrations over 300 ug/L, nor should formula for infants be made with that water for longer than 10 days.

We test our sources for total manganese on a monthly basis. The results of these tests will be posted on this page as they become available. All results are shown in micrograms per Liter unless otherwise noted. The value shown is the average for the month if multiple samples were taken.
Please review the public notice that was sent to our customers in November 2013 to see how these levels compare to guidance from MassDEP. Manganese levels typically decline as water moves futher away from the sources because it precipitates out of solution and coats the pipe walls. Although system levels are normally low (<300 micrograms per Liter) this level can easily be exceeded when sediment in water mains and home plumbing lines is disturbed.
A system map (14 MB) showing the test sites and water mains is available to help customers determine which sampling sites are closest to their homes.

The Town recently hired Woodard & Curran to fill the role of Owner's Project Manager for the Water Treatment Plant Project. The Commonwealth of Massachusetts requires an OPM for building construction projects that exceed 1.5 million dollars. The initial schedule calls for the design and bidding to be completed ahead of the May 2016 Annual Town Meeting where the Town will be asked to appropriate construction funding. If approved the plant will open during the summer or fall of 2017.

Our water storage tanks were inspected during 2011 and several deficiencies were found. Funding for the design portion of the tank repairs was approved at Town Meeting in May 2013.
November 18th Update: After going out to bid for the work, DN Tanks was awarded the contract for the repair work. They are currently working on the Garden Street Tank, cleaning and patching cement, installing a mixing system and installing fall prevetion equipment.
December 16th Update: Most of the repair work on both tanks is complete and the mixing systems are installed and will be operating soon. Some external work such as painting and a hatch replacement will be done in the spring.

The construction phase of the Washington Street Water Main Improvement Project begins on September 18, 2014. Joseph Cardillo & Son, Inc. is scheduled to start saw cutting the road and erecting signs. The water main on Washington Street, from River road to approximately Colrain Road, will be replaced as part of this project along with all water services (underneath the road), hydrants and tie-ins to side streets in the project area. Our goal is to complete all of the pipe work before winter and complete the finish paving in the spring.
September 29th Update: Cardillo has installed the new water main from Lockwood Lane to River Road on Washington Street. The new pipe will be filled this week. Testing is scheduled to begin October 6th. The pipe will be pressure tested, chlorinated and bacteria tested before being put into service. This process involves flushing the new main so customers may have discolored water during the flushing. We do not expect the discoloration to last long due the recent main break in the area which likely removed most, if not all, of the manganese.
November 18th Update: Cardillo is working on connecting Glen Road to the new water main today. This is the last side street that needs to be connected. The homes on Washington Street from Boxford Road to approximately Colrain Road need to be connected to the new main before disconnecting the old water main. We hope to have all of the pipe work completed by Thanksgiving. Final paving will be done in the spring.
December 1st Update: All of the tie-ins to the side streets are completed and Cardillo is working on finishing the installation of services. Work will continue this week but will be day to day depending on weather starting next week.
December 15th Update: All of the pipe work and temporary paving is complete. Work, including paving and landscaping, will start in the spring.

Drinking Water Advisory - Important information about manganese in your drinking water
Manganese is a nutrient that is part of a healthy diet. Drinking water may naturally contain manganese and, when concentrations are greater than 50 micrograms per Liter (µg/L), the water may be discolored and taste bad. Over a lifetime, the United States Environmental Protection Agency (EPA) recommends that people drink water with manganese levels less than 300 µg/L and over the short term, EPA recommends that people limit their consumption of water with levels over 1,000 µg/L, primarily due to concerns about possible neurological effects. Children up to 1 year of age should not be given water with manganese over 300 µg/L nor should formula for infants be made with that water for longer than 10 days.
Both of our water sources have exceeded the 300 µg/L threshold within the last year. The most recent test results show our source located on Perkins Row contains 394 µg/L of manganese; levels have varied between 150 µg/L and 370 µg/L in 2013 with an average of 313 µg/L. The most recent test result for our source located on North Street contains 94 µg/L; levels have varied between 70 µg/L and 1,270 µg/L during 2013 with an average of 391 µg/L.

What is a cross connection? It's an actual or potential connection between a potable water line and any waste pipe, soil pipe, sewer, drain or other unapproved source. These connections pose a threat to public health by allowing contaminants to be siphoned or forced into the public drinking water system under certain hydraulic conditions.
In a residential setting, cross connections include submerged hoses, lawn irrigation systems, chemical spray applicators, connections to private wells, boilers, solar heating systems and fire sprinkler systems. These connections, if left unprotected, could introduce contaminants to the water system. Consumers play an important role in protecting public health by notifying the Water Department of any cross connections and helping to eliminate or properly protect the connection by installing a backflow prevention device.
