The Hunters Point Naval Shipyard Superfund site (HPNS) does not include Parcel A. Historically, the Navy used this area for residential and administrative purposes. Based on information gathered since 1991, the United States Environmental Protection Agency (EPA) determined that Parcel A was suitable for work, recreation and residential use. As such, EPA removed Parcel A from being part of the HPNS on the National Priorities List of contaminated sites (or Superfund list).
In December 2004, the Navy transferred Parcel A (sub-divided into Parcels A-1 and A-2) to the City. In November 2020, the EPA issued a memorandum that stated Parcel A is suitable for residential use (see here).
To date, only land within Parcel A has been developed. The Navy's website has additional information on the cleanup and transfer of Parcel A here.
