Watercooler parts could be a source of organophosphate ester exposure

Watercoolers have become a staple in homes, offices and schools, but their tanks and parts are made of materials that could release unwanted or potentially harmful compounds into drinking water. In a preliminary study, researchers report that organophosphate esters (OPEs) were found in water dispensed from these systems, but they estimated that daily consumption would be far below the levels associated with health problems.
