Re: Groundwater Sampling Requirements
Dear Mr. Downs:

Mr.
This letter is to confirm a phone conversation between
Shannon Storrud and Mr. Don Verbica on May 15, 1990.
In a letter dated February 28, 1989, Hercules was granted permission to
delete pesticides/herbicides, radiologics, and bacteriologies from the
monitoring program for wells GW-1 through GW-61. Permission was granted
based on the fact that these analytes have never been detected at the Bacchus
Works and that quarterly sampling for groundwater quality and drinking water
parameters had been completed for one year.
During the discussion, Mr. Verbica gave verbal permission to delete these
same parameters for wells GW-66 through GW-69 beginning second quarter 1990.
Wells GW-66 through GW-69 have been monitored for one year according to
Table 3 as outlined in the above referenced letter.
Mr. Storrud also requested permission to discontinue sampling GW-56. In
this particular well, the sampling equipment (i.e., purge pump) has continued
to get caught in a section of confined or irregular well casing and only
after considerable effort with varying amounts of equipment breakage is it
retrieved. GW-56 is in close proximity to many other wells in the east NIROP
area and does not contribute any additional significant information over
those surrounding wells.
