Water Quality Sampling/Monitoring

Water Quality Sampling Locations

Water Quality Sampling 
Public Works undertakes water quality sampling during wet and dry weather conditions to satisfy requirements of the Massachusetts Department of Environmental Protection (DEP) Variance for Combined Sewer Overflow (CSO) discharges to the Alewife Brook, DEP Administrative Consent Order ACOP-96-1004 (Common Manhole Separation), DEP Notice of Non-Compliance NON-NE-00-1004 (Alewife 308 Letter), and EPA's National Pollution Discharge Elimination Program (NPDES) for stormwater (MS4) permit. Water quality sampling is also conducted at various locations as part of the DPW's continuing effort to identify and remove illicit connections.
