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.

The NYSDEC and NYSDOH have approved the Final Engineering Report and Site Management Plan; these are the last major documents related to the remediation of the former MGP and have been posted on this website.

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.
