The laboratory staff collect and analyze samples to determine compliance with permit limitations. After the samples are collected, they are returned to the laboratory and checked in. The pertinent sampling information is documented and the sample is preserved, if necessary, to ensure the quality of the sample is maintained.
The data generated to determine compliance with permit limitations is compiled and reported monthly to the South Dakota Department of Natural Resources. The operations staff uses the performance data to make operational decisions. The laboratory analyzes for approximately 20 different pollutants.
