Remedial Investigation

Remedial Investigation field work at the former Williamsburg Works MGP is being conducted under a New York State Department of Environmental Conservation (NYSDEC)-approved Remedial Investigation Work Plan (RIWP). The work includes the installation of soil borings, monitoring wells, and sediment cores to gather information required to determine the nature and extent of impacts at the former Williamsburg Works MGP.

Based upon the findings of the field work completed to date, National Grid and NYSDEC agreed that additional off-site investigations were needed in the vicinity of the MGP. The off-site work is described in the September 3, 2010 Supplemental RIWP which is available in the Key Documents/Major Reports section of this website. The initial phase of the Supplemental Remedial Investigation field work was conducted from October to December 2010. Supplemental Remedial Investigation field work is expected to when access is granted by private property owners.

Interim Remedial Measure

The Pre-Design Investigation field work for the 50 Kent Avenue Interim Remedial Measure (IRM) will commence after access is granted by private property owners as part of the NYSDEC-approved IRM Design Work Plan. The work includes the installation of soil borings, monitoring wells, and test pits to gather information required to determine the design parameters of the remedial approach at the 50 Kent Avenue parcel of the Williamsburg Works MGP Site.

No activities are planned pending access agreements.
