Notice: Since this article was written, AnneLandmanBlog has found out from Colorado Department of Public Health and Environment (CDPHE)’s Hazardous Waste department expert in charge of dealing with closed firing ranges that Ascent contractor Vertex Companies of Denver utilized the wrong type of post-remediation testing technique for this facility, rendering the results in the report Ascent posted on August 11 invalid and essentially useless. Read more about it here.
The 8-page, post-lead remediation testing report that Ascent Classical Academy Grand Junction posted on its website August 11, 2023 (pdf) shows that 30 of the 66 sites tested for lead in the old Rocky Mountain Gun Club building at 545 31 Road, which is to serve as the new charter school, still have lead levels 5-23 times above HUD allowable limits.
And Ascent did not test the air inside the facility.
The post-remediation testing was performed by the Vertex Company, which included a disclaimer in the report that essentially says it wasn’t feasible to test all areas of the building, so there may still be areas where lead dust levels exceed HUD limits.
