Site Summary

The Alkali Lake Chemical Waste Disposal site is in Lake County, Oregon, about 60 miles north of Lakeview.  The main disposal area occupies about 10 acres just west of Alkali Lake.  Alkali Lake is dry most of the year, as are most surface water bodies in this area.  About 25,000 drums of pesticide manufacturing waste were disposed of here in the late 1960s and early 1970s.  In 1976, the drums were crushed and buried in place in shallow trenches.  Despite the large quantity of toxic materials, it does not present a significant risk to the public or the environment because the waste has been buried and fenced, and the site's location is about 35 miles from the nearest town.
