The document outlines Utah's Drinking Water Source Protection Program, which aims to protect drinking water sources from contamination. It discusses the history and requirements of wellhead and source water protection in Utah. Source protection plans require delineating groundwater and surface water protection zones, inventorying potential contamination sources, and developing management programs to control risks. While source protection is mandatory for public water systems, local land use control requires cooperation from counties and municipalities through ordinances.

- 2. History of Drinking Water Source Protection in Utah Wellhead Protection Program – 1986 amendments to SDWA. “Drinking Water Source Protection” program because we include springs and tunnels. Source Water Assessment Program - 1996 amendments to SDWA. Added surface-water sources and existing sources in transient non-community systems.

- 4. Source Protection Plans Delineate protection zones PCS Inventory and Assessment of Controls Management Program for Existing and Future PCSs
- 5. Ground-Water Protection Zones Zone 1 – 100-foot radius Zone 2 – 250-day ground-water time of travel (TOT), boundary of aquifer or ground-water divide, whichever is closer Zone 3 – 3-year TOT… Zone 4 – 15-year TOT… Critical area Well Bacteria Waivers Chemicals and Planning
- 7. Surface-Water Zones Zone 1 – ½ mile from HWM, 100 ft down-stream to 15 miles upstream, limit of watershed or state line Zone 2 – 1000 ft from HWM, additional 50 miles upstream… Zone 3 – 500 ft from HWM… Zone 4 – remainder of watershed or state line
- 8. Potential Contamination Source Inventory and Assessment of Controls Inventory and prioritize all PCSs in protection zones Identify and Assess Current Controls
- 9. Management Programs Developed at the local level by the public water system. Land use authority is held by counties and incorporated cities and towns. Land management strategies may be regulatory or non-regulatory.
- 10. Local Ordinances 10 counties now have ordinances. 27 communities have ordinances. All Counties with populations >125,000 have adopted source protection ordinances.
