Puget Sound Boatyards: Zinc, Copper, Lead, and Hardness Concentrations in Receiving Waters
Puget Sound Boatyards: Zinc, Copper, Lead, and Hardness Concentrations in Receiving Waters (Number of pages: 51) (Publication Size: 2MB)

|Description||The Boatyard General Permit (BGP) includes numeric benchmarks for copper that apply to stormwater runoff from boatyards. The BGP uses copper as an indicator parameter for zinc and lead, also associated with boatyard runoff.
In response to a ruling by the Pollution Control Hearings Board, the Department of Ecology conducted a receiving water study to obtain data to verify or modify the metals translator and hardness assumptions used to develop the benchmarks in the BGP. Surface water samples were collected at five locations in the vicinity of Puget Sound boatyards in September 2008 and January and May 2009. The samples were analyzed for total recoverable and dissolved copper, lead, and zinc; hardness (freshwater); and total suspended solids and salinity (marine water).
