In order to restore Virginia waterways to health, the Virginia Department of Environmental Quality (VADEQ) issues pollution diets setting limits on the amount of bacteria that can enter County waterways with documented high bacteria pollution. These limits are known as Total Maximum Daily Loads (TMDLs).
James City County is required to have a Virginia Stormwater Management Program (VSMP) permit to discharge stormwater into local waterways. The specific permit is referred to as the Municipal Separate Storm Sewer System (MS4) General permit.
The Division has been working with citizen monitors to sample streams in the County. There are 2 programs volunteers are involved with - bacteria testing, and stream insect collection and identification.
