Since acquiring the Colonial Water Company systems in December 2021, Aquarion has been focused on improving water quality, increasing system reliability, and promoting conservation. The presentation at the link below provides a description of the water systems and the actions we’ve taken to improve the systems.

Beginning in July 2022, we began experiencing discolored water in our system. We’d like to explain the cause of this discoloration, what we’ve done to address it, and additional actions we’re taking.
There are three separate service areas in our distribution system (see map):
We are experiencing discolored water in the Dover Main System—specifically in the main pressure zone.
Prior to December 2021, when Aquarion acquired the water systems, there were periods of discolored water in the water systems. This discolored water was caused by naturally occurring iron and manganese in the water from the three wells at the Francis Street wellfield.
When Aquarion acquired the water systems in Dover, we evaluated the water quality of our three Francis Street wells and changed the operation so that we were primarily using the well with the best water quality. We also cleaned the water mains (clearing out historic deposits of iron and manganese sediment) by flushing water through hydrants. These actions resolved the discolored water issues.
We have continued to monitor the level of iron and manganese in these wells. Unfortunately, we observed an increase in the manganese levels in the wells. This has led to discolored water in our system.
When Aquarion acquired the water systems in Dover, we determined that Knollwood Drive wells had better water quality than Francis Street and Draper Road wells. The Knollwood Drive wells also have additional capacity.
Due to the design of the pressure zones, the Knollwood Drive wells can only provide water for customers in the downtown pressure zone. Aquarion has been constructing projects at three locations in town that will address that issue, and instead allow us to provide many of our customers with water from the Knollwood Drive wells.
These projects include:
The first two projects have been completed. The third project will be done by the end of September 2023.
We also continue to remind our customers about the 2-day per week irrigation schedule. When irrigation systems turn on in the early morning, more of our wells need to turn on to meet the increased demand. This means that we have to use our wells with lesser water quality to meet these irrigation demands. If all of our customers adhere to the irrigation schedule, we can reduce the use of these wells.
Please refer to our water quality reports to learn about the quality of the water we provide to our customers in Dover. Our reports include information on the health effects of manganese.
Aquarion Water Company is reimbursing Dover, Massachusetts customers for weekly water purchases made after September 1, 2023, for discolored water issues in the Dover Main System (see eligible streets).
The water that we provide to homes served by our Springdale Farms System (PWSID MA3078008) comes from two wells located on our property at the end of Old Colony Drive (see map).
Test results in 2022 showed that the PFAS6 levels in the water from these wells had increased and exceeded the allowable level (referred to as the Maximum Contaminant Level or MCL) set by the Massachusetts Department of Environmental Protection (MassDEP) for the period 06/01/2022 to 09/30/2022 and 10/01/2022 to 12/31/2022.
The PFAS test results are included in the Notices for both periods (1/10/23 Notice, 10/5/22 Notice). PFAS levels subsequently decreased and were below the MCL in early 2023. For past months’ PFAS results, please visit our PFAS FAQs page. Note that compliance with the MCL is based on the quarterly average of three months of test results.
This is not an emergency. If it had been, you would have been notified within 24 hours. MassDEP requires us to distribute this Notice within 30 days of receiving the results for the last sample collected in each quarterly compliance period. Although this is not an emergency, you have a right to know what happened, what you should do, and what we did and are doing to correct this situation. Please refer to the Notices (1/10/23 Notice, 10/5/22 Notice) for this information.
We are taking the following corrective actions:
Aquarion Water Company is reimbursing households served by our Springdale water system for bottled water purchases made after October 1, 2022 because PFAS levels in the well water for that system exceed the regulatory limit.
