DESCRIPTION:
 |
A site reconnaissance and
records review conducted during the Phase I ESA revealed
that the subject property had been utilized as a bulk/commercial
fueling station since 1971. Six USTs, and two ASTs were
observed on the property.
After preparing a Health and Site
Safety Plan (HASP) and following a Quality Assurance Procedure
Plan (QAPP), ECI advanced borings and collected soil samples
with proper preservative and submitted the samples under chain
of custody for analysis for VOC’s, PNA’s and lead. Selection of
parameters and location of soils samples were based upon the
storage of gasoline, diesel fuel, and kerosene in under ground
storage tanks (USTs) above ground storage tanks (ASTs). A
biased sampling plan was designed, based upon the location of
the USTs, ASTs, and subject property features, e.g. drinking
water well, utilities, groundwater flow, etc. Each sample core
was screened for VOCs in the field using a P.I.D meter. Samples
with the highest reading were taken to the lab for confirmation from each boring. A written report describing all field
activities was provided.
Confirmation soil samples revealed no concentrations that
exceeded the exposure pathways of
soil volatilization to indoor air inhalation, direct contact,
ground water surface water interface, or drinking water. There
was no indication of offsite migration by any of the identified
substances.
