The Water Quality Research Foundation (WQRF) today announced the release of a new interactive online map that provides occurrence information on 57 contaminants in U.S. drinking water. The map includes 10 years of occurrence data provided by states and through EPA’s Fourth Unregulated Contaminant Monitoring Rule. It shows statistical summaries of all data -- not regulatory compliance. A video on the Contaminant Occurrence Map website provides an overview on how the map might be used by water professionals or consumers. Drinking water utilities may receive inquiries from media or consumers about water quality information included in the interactive map. Utilities with questions about the data can contact Kim Redden at WQRF. The Contaminant Occurrence Map was created as part of a WQRF-funded study led by Corona Environmental Consulting. According to WQRF’s announcement, the study “began as an inquiry of regulated contaminants for concentrations below the Maximum Contaminant Levels (MCL) and above the Maximum Contaminant Level Goal (MCLG), but the project quickly was recognized as an opportunity to include data for aesthetic contaminants that cause staining, taste and odor issues (i.e. chlorine, chloramine, iron and hardness) which has long been requested by the industry.” Other questions about this advisory can be directed to Greg Kail , AWWA’s director of communications.
