Technical report for the alkali lake ecological assessment, phase 1 reconnaissance (FY 91 and FY 92)
The report summarizes the results of three field survey trips (June and September 1991, May 1992) taken to investigate the ecological effects associated with the release of over a million gallons of hazardous waste from herbicide production on the Alkali Lake playa. Sampling of soil, sediment, groundwater, soil-dwelling invertebrates and vegetation confirmed that hazardous materials from the waste disposal area are migrating westerly within the shallow aquifer to West Alkali Lake. Two areas of dead vegetation were identified and permanently marked to determine if these areas are changing in size and location. Preliminary calculations using a linear food-chain model suggested that small mammalian herbivores would probably not display adverse effects due to dietary exposures to the contaminants. However, nestling shorebirds may be exposed to concentrations potentially associated with adverse biological effects.
