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. With the completion of additional access agreements, the last of the currently proposed Supplemental Remedial Investigation field work will be completed in late 2012.

The Pre-Design Investigation field work for the 50 Kent Avenue Interim Remedial Measure (IRM) includes the installation of soil borings, monitoring wells, and test pits to gather information required to determine the design parameters of the interim remedial measure at the 50 Kent Avenue parcel of the Williamsburg Works MGP Site. With the exception of one season of background noise monitoring, PDI field work was completed in February through April and August of 2012. The remaining, seasonal, background noise monitoring will be completed in November 2012.
Activities Week of October 15 – October 19, 2012:
