The City of Portland, Oregon, is approximately 50 miles from Mt. St. Helens, and the City's Bureau of Water Works was warned that an eruption of the volcano could have serious effects on water supply in the area. The city's emergency plan included preparations for caustic soda addition to adjust pH, for increased chlorination if turbidity increased, for possible bypass of open distribution reservoirs, and for ash collection and rain sampling stations to determine composition and quantity of ash fallout in the watershed. The eruptions' impacts on the City of Yakima are discussed as well.
