Precipitation was sampled for one year, 2/82 until 2/83 at four sites west of the Cascade Mountains in the state of Washington. Wet samples of one week duration were analyzed for sulfate, nitrate, ammonium, chloride, calcium, sodium, potassium, magnesium, arsenic, lead, zinc, cadmium, copper and phosphate. Measurements were also made of pH, conductivity and rain volume. The precipitation was found to be acidified with the acidification more closely associated with sulfate than nitrate. The volume weighted conductivity of precipitation concentrations of arsenic, potassium, copper, zinc, and cadmium each averaged less than 6 micro-grams per liter but results showed poor reproducibility.
