Groundwater Data Exchange – Sharing Environmental and Public Health Information


The New York State Department of Health (DOH) and New York State Department of Environmental Conservation (DEC) received funding under the EPA Exchange Network Grant program to develop a Groundwater Data Exchange (GWDX).  The objective of the GWDX project is to increase the effectiveness of the New York State Brownfield and Groundwater GIS program, which supports and enhances the remediation, protection and management of groundwater resources in the State of New York.  Multiple new Exchange Network data exchanges were developed to provide program staff in each agency with greater access to the information they need to coordinate environmental and public health program efforts to protect resources and respond to contamination..

Through the GWDX project, DEC and DOH designed and developed several innovative new data flows over the Exchange Network.  Data exchanges from DOH to DEC include drinking water quality information and geospatial public water supply area locations, while data exchanges from DEC to DOH include regulated facility details, remediation sites, and hazardous materials spill information.  Most of these new data flows were designed and built from scratch including the development of new XML schema, flow configuration specifications, and the necessary data service components implemented on each organization’s Network Nodes.  The data flows between the two agencies will be used to improve program effectiveness by increasing the speed, timeliness, and efficiency of data use between partner programs, as well as to increase data use, integration, and access across institutional boundaries.


The project is unique in many respects:

  • Exchanges data supporting both environmental and public health objectives.
  • Introduces multiple new data flows.
  • Establishes bidirectional data flows between the two organizations providing close to real-time data synchronization.
  • Reuses existing Facility Registry System data flow.
  • Includes geospatial data expressed and transported using GML.
  • Integrates with existing or creates new application databases using common architecture.

This project also included upgrading the existing DEC Network Node to Windsor’s latest open-source solution, OpenNode2, and implementing OpenNode2 at DOH, thereby establishing the organization as a presence on the Exchange Network.
