Population of West Virginia ~ 1.8 million with ~ 1.4 million served by Public Water Supplies. Public water systems include the following: Community water systems Non-community non-transient water systems Non-community transient water systems Community Systems – 329 184 Groundwater 128 Surface Water (~76% of population) 17 GWUDI Non-Community System – 641 619 Groundwater 14 Surface Water 8 GWUDI
Drinking Water Watch will provide online information on the quality of water produced by community water supplies in West Virginia. The Drinking Water Watch Web Portal will allow citizens to directly access drinking water monitoring data and other information for community water systems in West Virginia. The information is of interest not only to consumers of the water supply but nearby private well owners can also quickly check on potential contamination threats. Although water supplies are required to directly notify customers of any violations of federal drinking water standards and provide an annual Consumer Confidence Report, the web site increases the accessibility of information to the public.
