Water quality reports

The purpose of the Water Quality Report is to ensure that the Regional Wastewater Services Plan reflects current environmental conditions. It is also to track the progress of the Executive's comprehensive water quality monitoring program of streams and water bodies that are or could be impacted by wastewater influent, effluent, sanitary system overflows, or CSOs.

Note: prior to 2006, the Water Quality Report was submitted in March of each year. This report is now included in the RWSP Annual Report per RWSP reporting policies.
