Final drinking water monitoring rule set for June

Article Abstract:

The EPA will promulgate a final rule requiring public water systems to examine drinking water for the presence of microbes and disinfection byproducts in Jun. 1995. Under the new regulations, water systems which provide 10,000-100,000 people with surface water or surface water-influenced ground water are required to analyze their source water for the presence of Cryptosporidium, Giardia, fecal coliforms and total coliforms. Those which serve over 100,000 people, on the other hand, should not only test for these pathogens but also look for other culturable viruses.

Would less frequent pesticide monitoring be better?

Article Abstract:

Studies conducted by the US Geological Service show that sampling of rivers for concentration levels of atrazine and other herbicides once every quarter could lead to underestimation of herbicide levels. Herbicides do not always show up in each sampling period because their concentrations exhibit strong seasonality. Thus, sampling once a year during specific months could lead to better estimates of herbicide levels.

EPA considering quick action on Cryptosporidium

Article Abstract:

The EPA is planning to enhance the surface water treatment rule (SWTR) contained in the Safe Drinking Water Act to address the problem of Cryptosporidium contamination. EPA officials believe the move is necessary, following several reports of contamination in 1993 which affected thousands of people. Under the proposed enhanced SWTR, the maximum contaminant level goal for the microbe will be set to zero.
