The Modular Wetlands device to be tested is located in a non typical situation. Unlike a storm event that typically contains higher concentration during the first 2 hours our site has a fairly consistent flow of wash water that is estimated to be consistent through out the day. For this reason, composite samples were taken over a two hour period. The intent of the sampling was to establish a composite pollutant sample. This was done by dividing all of the containers and bottles to be filled for testing into ten equal parts. The grab sample was taken.
