Wastewater is pumped from South Ditch into Company Lake and discharges to the Columbia River via the outfall ditch. Much of the waste at the site has been removed, and removal actions are continuing. Studies are currently underway to determine the extent of environmental contamination and subsequent clean-up efforts which will be required. People may be exposed to contaminated soils and sediments in the area bordering the Columbia and Sandy rivers. This area is accessible by both boat and car.
People often enter the area for recreational purposes and to pick blackberries that grow there.
The area north of the dike has warning signs at access points to the North Landfill and Company Lake. Contamination at the site may have contributed to contamination of fish in the Columbia River, although it is difficult to determine what effect the site may have. Levels of PCBs in Columbia River fish are similar to levels which are seen nationwide. Workers at the Reynolds site may also be exposed to contaminated soils and sediments, particularly those workers who are involved in outdoor activities. They may be exposed to significant amounts of fluoride by accidentally ingesting small amounts of the contaminated soils and sediments.
