The EPA proposed approving another pesticide containing forever chemicals for crops such as canola, corn, soybeans, and wheat.

This study provides the first retrospective analysis of the causal impacts of the 2001 US Safe Drinking Water Act (SDWA) Arsenic Rule on arsenic (As) occurrence in public drinking water systems. Using publicly available SDWA compliance data, we employ a difference-in-differences strategy that compares As concentrations before and after the promulgation of the rule for treatment relative to control water systems, defining treatment based on whether a water system had ever sampled As concentrations above the rule’s 10 μg per liter (μg/L) threshold before the Rule was published. We find that annual mean As concentrations in treatment systems fell by almost 5 μg/L (p < 0.01) after 2001 relative to control systems, representing a decrease of about 38% compared to pretreatment levels. In light of the Rule’s projected net costs at the time it was promulgated, assessment of the Rule’s realized impacts using actual measured As concentrations from a nationwide sample is an important first step in retrospective benefit–cost analysis.

The Department of Defense has recently delayed the cleanup of PFAS chemicals at more than 100 military bases.

One expert told Newsweek that while the findings are "not surprising," the scope and scale of these chemicals is "concerning."

In a letter to EPA Chief Lee Zeldin, Rep. Chellie Pingree, D-Maine, cited a recent ProPublica story that quoted government scientists saying a yet-to-be-released report on the toxicity of PFNA was rea...
