Removal Responses

Removal responses are common at Superfund Sites when the contamination poses an immediate threat to human health and the environment. Removals are classified as either time-critical or non-time-critical depending on the extent and type of contamination. Site managers have many logistical considerations to balance under high time constraints. The documents below are a partial list of EPA's guidance for removals. The remainder are available through the EPA Removal Team.
