Enclosed are the original and a copy of the stormwater monitoring results for the first half of
2021 for our Willow Springs Lane facility. Our four stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.
Sincerely,
Mount Vernon Chemicals, LLC/Apollo Chemical
