EPA is announcing a major expansion and additional enhancement of the Water Contaminant Information Tool (WCIT). WCIT is a secure, online database profiling chemical, biological, and radiological contaminants of concern for drinking water and wastewater utilities. The agency has now added a compendium of 700 new contaminants with details on more than 212 analytical methods. EPA has also completed enhancements of the WCIT search feature. Expanding the range of data in WCIT enables water utilities, public health officials and federal, state and local agencies to better plan for and respond to an “all-hazards” contamination incident. Registering for WCIT is easy and free.
