Wollaston beach expands Quincy Bay forming part of Boston Harbor.

Wollaston Beach is now part of the Quincy Shore Reservation which was introduced by the legislative act in 1899.

Wollaston Beach is the largest in Boston Harbor with roughly 2.3 miles (3.7 km) of shoreline.

The Wollaston beach promenade has a significant seawall as it is impacted by coastal tides.

Based on water quality tests determining levels of enterococcus, currently, the beach is not unacceptable for bathing.

This was as a result of the archaic sewerage system dumping approximately 138 tons of waste daily into Boston Harbor.

Wollaston Beach had to be permanently closed for shellfishing and swimming given the toxicology of the water quality.

In 1982, it was determined that the Commonwealth of Massachusetts had knowingly violated and breached the federal Clean Water Act.

In 1990, Wollaston Beach was selected by the Environmental Protection Agency as an Estuary of National Significance given the history.

Despite the environmental challenges, Wollaston Beach is a populated summer destination for enjoying the considerably large promenade.
