Discharge was required due to numerous smaller <br />storm events. A pump was used to discharge the water in <br />order to maintain the 10 year-24 hour storm event retention <br />volume. It did not occur as a result of a 10 year-24 hour <br />storm. <br />The results of sampling are described on the attachment. All <br />samples were collected as grab samples from the surface of <br />the pond at approximately 3:00 P.M. on the date specified <br />above. The pH of the discharge was measured at 7.8 in the <br />field using a colormetric wheel. <br />If any additional information is required, please don't <br />hesitate to contact us. <br />/~Gl~6G( ~!!i~ <br />Rade H.
