EPA Defends Draft Water Criteria For Beaches From Waxman's Criticisms

摘要

Epa is defending its recently released draft water quality criteria for protecting against human health risks associated with bacterial contamination at beaches from criticisms leveled by Rep. Henry Waxman (D-CA) and environmentalists who charged the agency had failed to use recent epidemiological data that they say suggests the need for stricter limits than what the agency proposed. In a Jan. 12 letter to Waxman, acting EPA water chief Nancy Stoner says the draft revised criteria is based on the best available data at the time of developing the document, including recent epidemiological studies, new water quality indicators and analytical methods, approaches to quantitative microbial risk assessment (QMRA) predictive modeling and microbial source tracking.
