and Massachusetts Bay
Contingency Plan Exceedances
MWRA's NPDES discharge permit requires MWRA to report Contingency
Plan exceedances to regulatory agencies and the public. These notices
are triggered by unusual results of effluent or ambient
monitoring. Effluent monitoring takes place in the treatment plant,
while ambient monitoring examines the environment surrounding the
outfall in Massachusetts Bay.
Caution and Warning Level Exceedances
Many of our reports are in PDF format, which requires Adobe
Acrobat Reader®, a free program available from Adobe
Systems. To request a paper copy of any report, please contact
the MWRA Environmental Quality Department at 617-788-4941, or e-mail us at email@example.com.
