Gentlemen:
SLIC; PCE INVESTIGATION, PAUL'S DRY CLEANERS, 214 HIGUERA STREET,
SAN LUIS OBISPO; REVIEW OF GROUNDWATER INVESTIGATION REPORT
We received a letter report dated February 13, 1992, prepared by
your consultant (SEACOR) titled: RESULTS OF GROUNDWATER
INVESTIGATION 214 HIGUERA STREET SAN LUIS OBISPO CALIFORNIA.
Thank you for submitting this report. Conclusions made on Page 4
of the report state, "...it appears unlikely that the facility is
a major contributor of PCE to groundwater in the area." This
conclusion is unsubstantiated because it is based on results from
three wells installed on the subject site, one cross gradient and
two upgradient.
In my letter to you dated November 27, 1992, I specifically stated,
"We will accede to your preference to keep the wells onsite
provided groundwater in the downgradient southwest and southeast
corners of your property is tested." However, you elected to
dismiss the directive in the November 27 letter, and instead direct
your consultant to install the one well at the southwest corner and
two wells at the upgradient property corners.
In support of your actions your consultant states, "Increasing
levels of PCE with proximity to Higuera Street would suggest an
off -site source of groundwater contamination rather than a plume
U11-6ite. sewer main beneath Higuera Street could
represent one such off -site source. Thus, a well installed near
the southeastern corner of the subject site would likely detect PCE
associated with an off -site source and would be an unlikely
location to detect an on -site source of PCE, if present." My Staff
was aware of your consultant's point; that's why my staff and your
consultant previously agreed it would be best to install a
monitoring well just south of the restaurant as depicted on the
enclosed Figure 4. However, you dismissed their recommendations
because you insisted all monitoring wells be located on your
property.
We find your reasons for not installing a downgradient monitoring
well unacceptable. It is irresponsible for us to allow you to talk
us into a less desirable well location on the southeast corner of
a
1,4'.
Jim and Angelo Marabito -2- March 23, 1992
your site, then allow you to talk us out of it because it is a less
desirable well location than the proper location we sought in the
first place.
Pursuant to Section 13267 of California's Porter -Cologne Water
Quality Control Act, we request you direct your consultant to
install a monitoring well downgradient of your site and monitor
groundwater as previously directed. You may install the well on
the southeast corner of your site as we previously acceded, or on
the adjacent restaurant property as depicted on Figure 4. However,
the well must be installed, a sample of shallow groundwater
collected and analyzed and results submitted to us by May 11, 1992.
As before, questions regarding this
Richard Aleshire (542-4631) or Robert
