SEMS Search User Guide

SEMS bannersems imageSEMS is the official repository for site and non-site specific Superfund data in support of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). It contains information on hazardous waste site assessment and remediation from 1983 to the present.

This is a brief user's guide to the SEMS Search. Select from a variety of different search options and output options as detailed below. Contact us if you have any suggestions for improvements to these pages.

Select more than one search option at a time to speed up the search and make the retrieval more focused. Only those facilities matching all specified criteria will be retrieved.

Information in the SEMS database can be freely accessed through the use of this search. The complexity of the search is up to the user.

Develop searches that return small batches of data and terminate the session as soon as the searches have been executed, so that others can access the database.
