Short Description

The state of Washington adopted new Water Quality Standards for dissolved metals in 1992. These changes in standards, combined with the lack of compatible data, resulted in the removal of 48 of the 61 locations considered for listing in the draft 1994 303(d) list. Follow-up low-level metals information collected in May and September of 1994 at these 48 locations showed their removal is supported by in-stream metals concentrations. However, five locations did have metals concentrations that were more than one-third the chronic criteria.

Abstract

Long Description

These five locations were: Juanita Creek, Fairweather Bay tributary, Little Bear Creek, Fife Ditch, and Salzer Creek. Only one of the five, Fife Ditch, should be considered for continued metals monitoring. This recommendation is based on: (1) the elevated arsenic concentration in May 1994 that was more than one-half the chronic criteria, and (2) the proximity of this location to a potential source.
