CalEPA NEIEN Water-related Data Exchange

Water TowerCalEPA National Environmental Information Exchange Network (NEIEN) Water-related Data Exchange Projects

CalEPA is either participating or acting in a project oversight role on several projects related to water. These projects are organized as follows:

  • State Water Resources Control Board
    The SWRCB completed a beach water quality monitoring NEIEN project. The project was developed to demonstrate the sharing of beach water quality/public health data and public warning information among local, state, and federal involved parties. http://beachwatch.waterboards.ca.gov/BeachWatch/
  • State Water Resources Control Board
    The SWRCB completed the first phase of the California Integrated Water Quality System (CIWQS) NEIEN project. CIWQS is a computer system used by the State and Regional Water Quality Control Boards to track information about places of environmental interest, manage permits and other orders, track inspections, and manage violations and enforcement activities. CIWQS also allows online submittal of information by Permittees within certain programs and makes data available to the public through reports. http://www.waterboards.ca.gov/water_issues/programs/ciwqs/
  • Department of Water Resources
    DWR has a Surface Water Ambient Monitoring Program (SWAMP) NEIEN project underway. This project collects and exchanges water quality data as part of the Bay Delta and Tributary (BDAT) project. http://bdat.ca.gov/index.html
  • Safe Drinking Water Information System (SDWIS)
  • Within the Division of Drinking Water and Environmental Management in the California Department of Public Health (formerly known as the Department of Health Services), there exists the Public Drinking Water Systems program which regulates public water systems; oversees water recycling projects; permits water treatment devices; certifies drinking water treatment and distribution operators; and supports and promotes water system security. As part of this program, information is provided to the US EPA’s Safe Drinking Water Information System (SDWIS).
  • SDWIS Data Exchange Node Project
    As part of a grant project being jointly conducted by the California Department of Public Health [CDPH], University of California at Davis (Information Center for the Environment [UCD-ICE], and the CalEPA, the CDPH Public Drinking Water Program is providing SDWIS data on drinking water wells to the CalEPA via an Exchange Node interchange between CalEPA and UCD/ICE. This project demonstrates the use of this technology for exchange of regulatory data.
