| Description |
Grays Harbor is a large estuary in southwest Washington in Water Resource Inventory Area 22. Grays Harbor was on the list of impaired waters (303(d) list) for fecal coliform (FC) bacteria in 1996. Ecology’s Environmental Assessment Program conducted a Total Maximum Daily Load (TMDL) study during March 1997 – April 1998. Samples from the storm drains were taken February through April 1998. The overall goal of the 2010/2011 monitoring project was to characterize FC bacteria concentrations in urban stormwater drains in the cities of Aberdeen, Hoquiam, and Cosmopolis during the wet season of 2010/2011. All 16 urban drain sites and both stream sites exceeded the bacteria water quality criterion. Efforts should be made by all three cities to reduce sources of bacteria to the stormwater systems. |
