Enclosed are the original and a copy of the stormwater monitoring results for the first half of
2019 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,

Attached is the Rainfall record for the Burlington Airport for the Storm Water Monitoring Sample
collected on June 20, 2019, collected from 2:15pm—2:30pm. The rain gauge at the Apollo Chemical
Burlington Facility measured the even to be 0.14 inches at the time of collection.
The pH of each sample was measured using a calibrated electrode using buffer 4, buffer 7, and buffer
10. The samples were equilibrated to a temperature of 20.3°C prior to sampling.
