Corrosion Control Program Update

Housatonic Water Works Company announced today that it is seeking a modification of its corrosion control program. The Company is under direction from the Massachusetts Department of Environmental Protection (MADEP) to address exceedances of the Lead and Copper rule.

While working to meet the requirements established by MADEP, the Company has continued to evaluate the scientific and engineering aspects of both the lead and copper data and potential approaches for meeting compliance. As part of that continued evaluation, new facts have recently come to light which the Company believes should be considered.

Based on the new information the Company is now proposing an alternative solution to effectively meet the lead and copper rule which is simpler, and does not include the many disadvantages associated with raising pH:

  • Increased chlorine byproduct formation
  • Increased scaling from hardness in boilers, hot water heaters, and plumbing fixtures
  • Increased deposition of iron and other metals on plumbing fixtures (toilets would need to be cleaned more frequently).

“We have new data that was not previously available which we would like to be considered,” according to Company treasurer, James J. Mercer. For more information click here to read the MADEP Letter.
