Interactive Map of Thorium Survey Reports

EPA has agreed to host a web-based repository of radiation testing reports and other technical documents for the benefit of those conducting work within the rights-of way. These reports allow private utilities companies and city departments to easily check to see if an area has already been tested and determined to be clear of contamination, or if the area has never been investigated and still needs to be tested.

All links below and within interactive map are PDF files.
