Weekly Update, Week Ended October 14, 2011
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.
