Remedial Investigation

Remedial Investigation field at the former Fulton Municipal Works MGP is being conducted under a New York State Department of Environmental Conservation (NYSDEC) and New York State Department of Health (NYSDOH)-approved Remedial Investigation Work Plan (RIWP).  The work includes the installation of soil borings, monitoring wells, test pit excavations, and soil vapor points to gather information required to determine the nature and extent of impacts within the footprint of and adjacent to the former Fulton Municipal Works MGP.  National Grid continues to pursue access to complete the remaining proposed RI activities.

Based upon the preliminary findings of the RI 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 July 20, 2009 RIWP Addendum.  National Grid completed these additional off-site field installation activities at the beginning of August 2009.

Activities April 24 through April 30:

  • Completed utility clearance activities at a private property.
  • Completed the installation of the final proposed RI soil borings and the collection of groundwater samples at a private property.

Future (two week look-ahead) activities:

  • Survey RI borings and vapor intrusion sampling locations at a private property
