Our Annual Report on Drinking Water Test Results for 2010 describes how we treat, test and deliver tap water to your home. The MWRA and your local water department test up to 500 samples each week, and test for over 120 contaminants each year.
This report includes the results of those tests for 2010. This report is required under the federal Safe Drinking Water Act Public Law 104-12, Section 1414 (C), PWS ID #6000000.
