Rapid changes in dissolved humic substances in Spirit Lake and South Fork Castle Lake, Washington

January 1, 1988

One major effect of the eruption of Mount St. Helens, Washington, was a large increase of dissolved organic material in the lakes of the area devastated near the volcano. Much of this material was aquatic fulvic acid derived from plants and soils from the surrounding watershed. During the 3 yr after the eruption, substantial chemical changes occurred in the aquatic fulvic acid. -from Authors
