Many organic contaminants in the air and in drinking water need to be detected at very low-level concentrations. Research published by the laboratory of Prashant V. Kamat, the John A. Zahm Professor of Science at the University of Notre Dame, could be beneficial in detecting those contaminants. ... read more >>

Baby mice have severe growth problems when their mothers were given water containing arsenic – at levels considered safe for humans – when they were pregnant and lactating. Arsenic in drinking water has been linked to many health problems. The US Environmental Protection Agency (EPA) states that water containing up to 10 parts per billion (ppb) of arsenic is safe. ... read more >>

Measuring the benefits and costs of an improvement in water quality is often difficult. First, for a complete analysis, all relevant benefits and costs have to be measured. If some consequences cannot be monetized, then analysis becomes more complex, though feasible. The effects on all parties concerned have to be taken into account. Second, the physical benefits and costs have to be measured in ... read more >>
