LEGISLATION MANDATING PERCHLORATE MCL SEEN GARNERING LITTLE SUPPORT

A bill that would mandate a 6-part-per-billion (ppb) enforceable drinking water standard for the rocket fuel component perchlorate appears to have little support among affected stakeholders, who object to the measure on both procedural and substantive grounds.

PCL BILL MANDATING BORON PHG SEEN AS CHALLENGE TO DESALINATION

A bill sponsored by the Planning & Conservation League (PCL) requiring the state to set a drinking water limit for the element boron is seen as an effort to possibly hinder the development of desalination projects in the state, which the environmental group sees as a potential threat to the marine environment. Desalination industry representatives say boron does not pose a threat to the public or environment and that filtering the element to levels cited by the bill's proponents likely will be extremely costly and could stunt the technology's growth in the state.

EPA ADOPTION OF PERCHLORATE RISK LEVEL COULD BOOST DOD SITE STUDIES

EPA's adoption of a risk level for perchlorate, and the agency's inclusion of that level in its Integrated Risk Information System, could increase cleanups at military sites where the risk level would be used to develop site-specific cleanup goals, Defense Department (DOD) and other sources say.
