Note: the north during this rain event appeared to have significant
suspended red clay. Initially we were unable to determine the
source. but recently discovered a "washed out" hole adjacent to a
stormdrainplace where the integrity of the stormwater drain
appeared to be impaired. Work notification has been submitted
and project isis being developed for repairs. This should eliminate
the red clay
suspended solids.

At the time of this sampling event, several temporary storage tanks
were delivered to the site and were found to not be "clean" as
requested. While awaiting for the rental company to come and
remove, a rain event occurred and SW monitoring occurred with no
realization that such an event would exceed or reach benchmarks.
No other activities were underway to have such an impact, thus
these tanks were removed and the next sampling event showed
normal.
