Water Contaminant Information Tool (WCIT) Update
What is WCIT and who will use it?
The Water Contaminant Information Tool (WCIT) is a secure, online database under development by the
U.S. EPA that will provide information on contaminants of concern for water security. As a planning tool,
WCIT can be used to help create and update vulnerability assessments, emergency response plans, and
site-specific response guidelines. As a response tool, WCIT can be used to provide real-time data on water
contaminants to help first responders (including utilities) make better decisions. In addition, WCIT will
assist EPA to determine what information about priority contaminants is missing, which will direct future
research efforts.
WCIT users will include EPA Program Offices and Regions, other Federal
organizations, drinking water and wastewater utilities of all sizes, State drinking
water and wastewater programs, public health officials, environmental laboratories,
emergency first responders, and technical assistance providers.
                  What kind of information will I be able to find on WCIT?
                  WCIT will contain the most up-to-date information on water contaminants from peer-
                  reviewed sources and research.  It will include data on contaminant names, contaminant
                  availability, fate and transport, health effects and toxicity, medical information, drinking
                  water treatment effectiveness, potential water quality and environmental indicators,
                  sampling and analysis, and helpful response advice for utilities. Initially, only
                  drinking water information will be contained in WCIT. However, the process to gather
                  wastewater information has begun and these data will be added to WCIT later.

                  Who is helping EPA to design WCIT?
                  EPA established a User Workgroup to provide guidance on WCIT's design and
                  functionality. The membership of this workgroup includes representatives from those
                  agencies and groups (such as water utilities) who will be the ultimate users of WCIT.
                  EPA also established an Expert Workgroup to conduct initial and ongoing reviews of
                  the technical information contained in WCIT. These workgroup members are experts
                  on chemical or pathogen properties, fate and transport, contaminant monitoring, health
                  effects, or comprehensive contaminant data compilation and management procedures.
                                When will I be able to access and use WCIT?
                                Initial testing (also known as "beta" testing) of WCIT is complete, and
                                the first version of WCIT will be available in the early fall of 2005.
                                Currently, information for 16 contaminants has been entered into WCIT.
                                It will contain information for a total of 45 contaminants when it is
