Air Station in Squantum was abandoned and in ruins by 1970. Also during this year, the skeleton of a dog was found below a heap of shells in Squantum. The dog's remains were carbon dated to 300 AD. The remains of a few native Indians have also been discovered nearby. The sachem Chickataubut had his summer home at Moswetuset Hummock in the early 17th century. In 1972, federal and state laws mandated primary and secondary treatment for all municipal sewer systems, effectively taking the option for lesser treatment plants away from states. In 1984, due to the extensive pollution on Quincy's beaches, the City of Quincy filed a lawsuit in state court against the MDC. As a result, the Massachusetts Water Resources Authority (MWRA) was created to manage the cleanup of Boston Harbor. Judge Troy made a judicial decision that prohibited the attachment of any new buildings or homes to the existing sewer system until a plan was established to solve the sewerage overflow problem in Boston Harbor. In 1985, the MWRA assumed control of all of the MDCs water and sewer systems. Because these systems were below federal standards, a federal court order mandated the construction of a new waste water treatment plant on Deer Island. In 1993, National Guard bulldozers, with little public notice, began clearing the woods on Moon Island for a firing range that was planned to have lights for night shooting. Outraged local Squantum residents feared that the increased shooting on Moon Island would endanger them or even passing boat operators. The Seaside Environmental Alliance claimed the Boston Plan was a ruse, indicating that this expansion would affect the plans for any use of Moon Island by the general public. The public continues to be banned from both Moon and Long Islands. In 1996, the Boston Globe reported that Mayor Tom Menino and MIT engineer Clifford Goudey were planning a program to revitalize the aquaculture system in Boston Harbor and use the great tanks on Moon Island as a fish farm or a temporary home for tuna or lobster. The prices of both these fish types vary by season. The plan was to collect and store fish in the tanks and sell the fish at higher prices when they were out of season. Nothing has come of this plan to date. Today, Moon Island remains closed to the general public and is still owned by
