EPA Ecological Soil Screening Level (Eco-ESL) Guidance. The Eco-ESL guidance provides a set of risk-based soil screening levels (Eco-ESLs) for several soil contaminants that are frequently of ecological concern for terrestrial plants and animals at hazardous waste sites. It also describes the process used to derive these levels and provides guidance for their use. SADA version 4 does not include values from the draft guidance released in 2000; these values were included in SADA version 3. SADA version 4 only includes Eco-ESLs for chemicals addressed in the 2003 guidance.
Eco-ESL Avian . As of December 2003 avian Eco-ESLs were available for cadmium, cobalt, lead, and dieldrin. Eco-ESL Inverts. As of December 2003 soil invertebrate Eco-ESLs were available for antimony, barium, beryllium, cadmium, and lead.
Eco-ESL Mammalian. As of December 2003 mammalian Eco-ESLs were available for antimony, barium, beryllium, cadmium, cobalt, lead, and dieldrin.
Eco-ESL Plants. As of December 2003 terrestrial plant Eco-ESLs were available for cadmium, cobalt, and lead
Narrative statements are available for aluminum and iron, but no soil screening levels were developed.
