Combined sewer overflow (CSO): sewage mixed with rainwater spills from a shared sewer system. Sanitary sewer overflow (SSO): sewage spills from a sewer meant to carry sewage separately from rainwater. Treatment bypass: wastewater skips one or more treatment steps. Blended discharge: wastewater that skipped some treatment is mixed with treated wastewater. Outfall: a pipe or outlet where wastewater enters a water body.
Reported discharges per month
12 reported discharges, January 2022 to November 2026. Counted from 12 source-confirmed or annual reports.

Reported discharges by wastewater outlet
Wastewater outlets with the most tracked discharge records: 1 of 1, all years. Counts depend on reporting coverage and do not measure legal compliance or harm.
Massachusetts portal records begin June 30, 2022. Verified Data Reports arrive after the month ends, so the latest months count public notices.

How these charts are counted
We count each discharge once. Where a source publishes notices and confirmed reports, we use confirmed reports for an operator's month when available; otherwise we use notices. We combine revisions and exclude duplicate state reports copied by the U.S. Environmental Protection Agency (EPA). Monthly and yearly totals appear separately. Status hours follow this site's rules. Shaded gaps mean missing coverage, not zero discharges.
