The water quality in towns served by the Massachusetts Water Resources Authority is “excellent,” according to the 2011 Annual Water Quality Report released by the authority.
The MWRA met all federal and state drinking water standards, according to the report, which was released this week. Additionally, tests showed that water supplied by the MWRA does not contain traces of pharmaceuticals.
“We have some of the best drinking water in the county,” said MWRA Executive Director Fred Laskey. “The report is essentially a nutrition label for your drinking water, and the news is good.”
Of the 120 different contaminants the MWRA is required to test for, only eight were found and all were well below the maximum contaminant level allowed by the US Environmental Protection Agency, according to the MWRA’s report.
“Some tests are daily, some are weekly, and some are monthly; it depends on what the contaminant is. We take hundreds of thousands of tests annually,” said Joshua Das, the MWRA’s project manager of public health. “We collect samples at different stages [between source and tap]. We want to make sure anything we add for treatment wouldn’t have a contaminant in it.”
The MWRA began mailing copies of the report this week to over 850,000 homes in the 41 cities and towns that get water from the authority. In many communities, an insert will provide additional, specific information about municipal water systems, according to Ria Convery, a spokeswoman for the MWRA.
