RE: REQUEST FOR TIME COMPOSITE SAMPLING
Dear Mr. Gleason:

The Town of Maiden is requesting approval to collect samples on a •-=4
time basis rather than flow proportional sampling. The Wastewater
Plants influent pumps operate on a intermitting frequency instead
of a continuous one. Presently, our samplers collect 100 mL's
every 20 minutes. This sampling frequency yields approximately 8
Liters of sample daily. I discussed this matter with John Lesley
on December 18, 1995.
If there are any questions concerning this matter, give me a call
at [phone].
Best regards,
