DESCRIPTION:

Based on a
Phase 1 ESA, recognizable environmental conditions were believed
to exist on the subject property. Retained to perform a Phase
II ESA to evaluate the nature of soil and groundwater
contamination on the subject property. Additional investigative
and remedial phases were to be recommended if any found on site
contamination exceeded MDEQ criteria or appeared to have
migrated off site.
Developed and prepared a Health and Safety Plan (HASP) specific
for the subject property. Prior to engaging in field
activities, contacted MISS DIG to demarcate subsurface
appurtenances in the areas of investigation. Prepared a soil
testing grid for the areas of locations where formerly drums,
transformers and pads, pits, and soil and waste mounds were
located, as well as in the vicinity of the property sewers and
storm drains. Determined a grid interval and set the grid.
Advanced soil borings with a geoprobe and collected soil and
water samples. Properly preserved the samples and submit them
under chain of custody to a qualified independent laboratory for
analysis. Decontaminated the sampling equipment used between
each sampling event by washing the equipment with a
non-phosphate detergent followed by a clean water rinse.
Samples were analyzed for PCBs and the ten (10) Michigan metals,
utilizing MDEQ approved methodology, detection limits, and QA/QC
per MDEQ-ERD. Assessed analytical data via RBCA and MDEQ
Criteria and determined extent of contamination. Upon
completion of the field work and laboratory analyses, prepared
a report which included a description of all field activities,
analytical methodologies and results, soil boring logs, and a
scaled site map with sampling locations, and identification of
the areas of contamination. Findings, conclusions and an
opinion properly provided.
