To validate the event mean concentrations, flow data was obtained by a flow meter that measured gallons used in the entire boat wash area. The flow meter allowed use to accurately determine the amount of wash water flowing into the Modular Wetlands Device. The flow meter was not installed until approximately July 3 so no flow data was available prior to the installation.

Bacteria was not anticipated to be effected until the plants roots had extended to the bottom of.
