Project:

Subsurface Investigation for Delineation and Initial Assessment Report

DESCRIPTION:

 


Purpose of project was to delineate extent of contamination and determine if contamination was migrating off site.  USTs had previously been removed and a Confirmed Release was on file with MDEQ.  Sewer utilities across site as well as residential properties adjacent (south and downstream) to site posed concerns for off site migration.  Requested demarcations of subsurface appurtenances provided by MISS DIG.  Submitted Notification to do Work on Site to MDEQ in accordance with time restraints. Prepared a HASP specific for site.  Prepared a CAD site plan to scale.  Sampled walls and floor of excavation; sampled piping runs every 25 ft; and sampled near and under dispensers. Sampled at property lines of all four directional perimeters; and sampled near all utilities.  Using 3-inch over boring geoprobe piping, advanced borings for setting of 2-inch monitoring wells.  Developed, purged, and sampled monitoring wells.  Collected samples with appropriate preservatives and methodologies and submitted under chain of custody to qualified laboratory for analysis via SW-846 for gasoline parameters, diesel parameters, and waste oil parameters and metals.  Assessed the analytical data via RBCA and MDEQ Criteria and concluded high potential for off site migration toward residential property south.  Evaluated exposure pathways and revealed that sewer utilities were impacted.
