EPA Biosolids Screening Tool
EPA's Biosolids Program is working on finalizing the Biosolids Screening Tool (formerly referred to as the BCRAM screening tool). It has been scientifically peer reviewed and still needs to go through public review. Once completed and publicly reviewed, risk screening can begin (anticipated 2020). Based on the three EPA national sewage sludge surveys and the biennial review process, over 350 pollutants have been found in biosolids and need to be screened provided there are sufficient data.
