Some of the latest research conducted utilizing the boundaries collected through ICE and uploaded to the California Department of Public Health Environmental Health Tracking Program or CEHTP, the CDPH entity behind the creation of the online geographic tool.
The Information Center for the Environment (ICE) has enjoyed a long, lustrous relationship with the California Department of Public Health, (CDPH). One of our latest projects involves collecting drinking water service area boundaries for the state of California and creating a geospatial statewide dataset for CDPH use. Recently, the project has also caught the eye of CalWARN, a Wastewater Agency Response Network who is interested in the collection for emergency purposes. For example, in the event California experiences a Hurricane Katrina type catastrophe, this data will direct us to the most vulnerable water systems and cut off their distribution to prevent water supply contamination. However, California's drinking water systems come in a variety of categories.
