How lead is dispersed at shooting ranges (Georgia Dept. of Public Health/Seattle Times)
The Vertex Company LLC of Denver, which Ascent Classical Academy hired to test the old Rocky Mountain Gun Club building for lead contamination after the building was remediated, did the wrong kind of testing, says an specialist with Colorado Department of Public Health and Environment (CDPHE).
Caren Johannes of CDPHE’s Hazardous Materials and Waste Management Division Compliance Unit, who oversees closed shooting ranges, looked over online remediation report (pdf) that Ascent posted its website on August 11, 2023, and concluded that the Vertex Company did the wrong kind of testing for lead in the building, so their results will not be valid.
