Island system provided no treatment capability. It merely collected waste water and effluent, and pumped it out into Boston Harbor. During 1892, a garbage reclaiming plant was established on Moon Island. The plant was moved to Spectacle Island during 1912. By 1919, severe pollution from the Moon Island sewage outflow caused the closing of many of the clam beds and beaches in Boston Harbor and Quincy Bay. Also during this year, the Metropolitan District Commission (MDC) took over control of the Moon Island/Squantum Sewer System from the MSD. In 1933, the pollution of Boston Harbor worsened to the point that all clams taken in the area required purification processing before sale or consumption. Pollution on the Boston and Quincy beaches worsened. In 1939, a legislature committee found that Quincy Bay and Hingham Harbor were "revolting" and "in violation of all public health requirements." Both Boston and Quincy beaches have been closed since 1890. More than of raw sewage were being dumped into Boston Harbor daily. The following year, Massachusetts State planners recommended the construction of sewage treatment plants at Moon Island, Deer Island, and Nut Island in Quincy. On August 4, 1951, then Secretary of Labor, Maurice J. Tobin, dedicated the two-lane steel bridge from Moon Head to Long Island. In 1959, The Boston Fire Department constructed a fire-fighting training facility at the northern end of Moon Island. A concrete building was designed and built to simulate the various roof designs and window shapes found in the City of Boston. In 1960, the Boston Police Department established an outdoor pistol range on the southern side of Moon Island. This facility is now jointly used by the Boston and Quincy Police Departments. A cache of stone blades were found on a Squantum beach in 1961. These artifacts belonged to the early Indians who lived in the Squantum area. The Moon Island sewage facility was still operating in 1967, pumping about a million gallons of sewage into Boston Harbor. 15–20% of the sludge that was discharged with the outgoing tides returned on the next incoming tide. The result was that Boston Harbor and Quincy Bay became severely polluted. With the opening of the Deer Island sewage treatment plant in 1968, the discharge of sewage from the Moon Island facility was put on emergency standby status and the flow of the sewage to Moon Island was diverted to Deer Island.
