New Study of Toxicity Levels of pCBSA suggests lower screening thresholds

pCBSA (para-Chlorobenzene sulfonic acid) is one of the contaminants we have been following closely, and is a VOC resulting from DDT processing. We are particularly concerned with pCBSA in potential sources of drinking water, but very few studies have been conducted about protective screening levels for the toxin. See the most recent study of pCBSA toxicity levels conducted by US EPA, released January 2017:
