Water quality, compliance, and health outcomes among utilities implementing Water Safety Plans in France and Spain

Water safety plans (WSPs) are a preventive risk assessment approach used to manage drinking water hazards from catchment to consumer. Despite the WSP goal of reducing water contamination events, only one study has demonstrated WSP effectiveness at decreasing drinking water pathogen or chemical exposure and corresponding health improvements. We assessed the effect of WSP implementation on drinking water quality, compliance, and health outcomes at five locations in France and Spain. We found improved compliance, unchanged or improved water quality at all locations, and one utility showed a 4% reduction in acute gastroenteritis incidence. Our results suggest that WSP implementation provides quantifiable compliance and health benefits, and may benefit other high-income nations.
