The Beaches Science Advisory Committee meeting to discuss the new plan. |
It
has been a busy start to the year at Save the Harbor/Save the Bay. On February 2, just a
few days after our Metropolitan Beaches Commission Meeting, we were back
downtown for our Science Advisory Committee Meeting. The Committee is made up
of scientists and experts who advocate for clean water and the protection and
restoration of Boston Harbor and Massachusetts Bay. The Advisory Committee
issues water quality and beach flagging report cards to inform the public and keep
everyone healthy and safe when enjoying the beaches.
The
meeting opened with introductions and a bit of background as to why the group
was meeting to discuss King’s Beach in particular. King’s Beach, located
in the towns of Lynn and Swampscott, has been lagging behind some of our other
Boston beaches. With an average water quality compliance of 82% since
2011, King’s has the second lowest compliance rate after Tenean Beach in
Dorchester. With other Boston beaches averaging a 100% compliance rate, the numbers
at King’s are unacceptable. Kelly Coughlin, one of the committee’s water
quality experts and the one who presented all of the research at the meeting,
found that the problems at King’s Beach stem from Stacey’s Brook Outfall-which
receives sewage discharge from both towns. She also noted that King’s has
a wet weather problem, because after it rains the bacteria counts skyrocket and
there is a surcharge in the sewer system.

The
committee focused in on Enterococcus bacteria counts at the outfall and
the smaller outfalls that filter into it. To keep people safe the legal
limit of Enterococcus is set at 104 colony-forming units/100mL of water.
There have been days at King’s Beach where the number of colony-forming units
per 100 mL is well over 1000, often on days with wet weather. The
Committee determined that this is from bacteria and other waste getting into
the sewer systems and outfalls, and then being washed out to the beach when it
rains.
Eastern
Ave, the outfall in Lynn that discharges to Stacey’s Brook, has a higher number
of failed dry and wet days, however, because non-stormwater discharges are a
significant problem as well. The major contributors to pollution at
Stacey’s Brook are Eastern Ave and a combined sewer overflow (CSO) in Lynn and
from neighborhoods and underdrains upstream in Swampscott. Swampscott is
classified as a Phase II stormwater community and discharges under a general
municipal separate storm sewer systems (MS4) permit. However, the sewer
system is outdated, and part of the BSAC’s plan moving forward is the Sewer
Rehabilitation Phase 1, and $11 million sewer rehabilitation including relining
pipe, replacing sewer mains and service laterals, manhole rehabilitation and
spot repairs, and replacing residential sewer laterals in this area. In
November 2015 the EPA and Town of Swampscott entered into a Consent Decree to
identify and eliminate non-stormwater discharge to the storm drain system.
The
Lynn Water and Sewer Commission (LWSC) serves the city of Lynn, Nahant,
Swampscott and Saugus, and has an average monthly flow of 26 million gallons
per day. It completed separation of its stormwater system, which resulted
in fewer CSO activations, or less than 4 times each year. Lynn has a NPDES
discharge permit for its wastewater treatment facility and 4 CSO outfalls (1
CSO discharges into Stacey Brook). Lynn has a National Pollutant Discharge
Elimination System (NPDES) discharge permit for its wastewater treatment
facility and 4 CSO outfalls (1 CSO discharges into Stacey Brook).
It
also has a Small Municipal Separate Storm Sewer System (MS4) permit to
discharge stormwater to receiving waters.
During
the meeting, the committee identified four phases of the Illicit Discharge
Detection and Elimination project. Phase 1 is to map storm and sewer
systems, and prioritize the outfall. Phase 2 is the investigation stage,
which includes public outreach, verification maps, storm drain cleaning,
manhole inspection and flow monitoring, and field measurements. Phase 3
is the confirmation of illicit sources, removal, and post-removal verification.
The final phase is to monitor bacteria, ammonia, surfactants, pH, and
fluoride amounts. The current trajectory is a 15-year long project, with
funds coming in every other year. Save the Harbor / Save the Bay has
volunteered to help fund the gaps in data the committee identified. The
group will accelerate the process of cleaning up King’s and reduce the 15-year
number.
What’s
next for King’s Beach? Save the Harbor will be looking into data gaps and
potential costs, and the committee will come together after all sides look at
the problem again. To follow the updates on what the committee is doing and
what is new at King’s Beach and all Boston public beaches, follow Save the
