National Grid conducts quarterly groundwater sampling in accordance with the quarterly groundwater monitoring program in the Record of Decision. The reports are placed on the website (Major Reports) and in the Document Repository. Since the remediation was conducted, BTEX and total PAH concentrations have been generally decreasing in shallow groundwater on and adjacent to the site and are below historical levels. Concentrations in intermediate and deep groundwater have generally remained at, or near detection levels.

National Grid will also be finalizing a Construction Completion Report and a Site Management Plan for the former Sag Harbor MGP Site. Once both documents are finalized and approved by the NYSDEC and NYSDOH, the Site Management Plan will be implemented on National Grid property and the adjoining areas and residences.

National Grid will provide activity updates as developments warrant for the neighbors of the Sag Harbor Former MGP Site. Updates will include upcoming work, and information about any work that may impact normal community activities. The Archive section of this website includes the past Weekly Updates and the periodic submissions.
