EPA Re-Evaluates the Risk from Fluoride Exposure

There has long been a debate about the use of fluoride in drinking water, pitting those who strongly believe in the benefits of fluoride to dental hygiene against those who even believe that there is no safe exposure level for fluoride. Recent EPA risk analyses of fluoride in groundwater will likely result in lower drinking water standards for fluoride. While the major impacts of these efforts will likely be to drinking water fluoridation and the use of fluoride-based insecticides in agriculture, industries with environmental issues that include fluoride will also feel the backlash, resulting in greater investigation and remediation costs.

Will EPA Meet Its 2020 Goals for the RCRA Corrective Action Program?

EPA recently reported in its annual performance report for 2010 that remedy construction has been completed at 37 percent of the 3,746 facilities on the RCRA Corrective Action 2020 baseline. To meet the goal of the 2020 Initiative, EPA and authorized states need to have achieved remedy construction status at 95 percent of the baseline facilities by the year 2020. With only nine years to go, what are the chances of meeting this ambitious goal?

EPA Considers Establishing an Enforceable MCL for Hexavalent Chromium

Since 2008, EPA has been re-evaluating its 20-year old drinking water standard for total chromium with respect to the carcinogenicity of orally ingested hexavalent chromium (chromium-6), the more toxic species of the metal. EPA is being pressured about the findings of a draft assessment of chromium-6 by both industry (claiming overestimate of risk) and environmental groups (claiming underestimate of risk). Whatever the outcome of the argument, EPA is likely to establish a chromium-6 MCL that is significantly lower than the current total chromium standard. This will have major implications for sites investigating, monitoring, or remediating media impacted by chromium-6, as well as for our nation's municipal drinking water supply systems.

Ohio EPA Issues Latest Version of Draft 506 Rules (Multi-Program Groundwater Monitoring Rules)

Ohio EPA's first draft of the multi-program groundwater monitoring rules (OAC 3745-506), issued in 2006, was met with substantial comment from stakeholders and interested parties.
