2 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 2 Mission To protect the health of the people of Washington State by ensuring safe and reliable drinking water.

3 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 3 Source Water Protection Outline  Regulatory framework  Planning  Implementation  Case studies

4 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 4 Public Water System Classification  Group A – 4,000 (serve 98% of WA)  15 or more connections  25 or more people per day for 60 or more days per year  Group B – 13,000 (serve 2% of WA)  Less than 15 connections  Serve water less than 60 days per year  Private wells – individual wells

5 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 5 Group A Public Water Systems  Regulated by  Federal Safe Drinking Water Act  State Drinking Water Regulations  DOH Office of Drinking Water (ODW)  Implements and enforces regulations  Provides technical assistance  Source Water Protection  Required for all Group A systems

6 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 6 Group B Public Water Systems  Not subject to Federal regulations  ODW has agreements with many county health departments to regulate Group B systems  Source Water Protection  100 ft radius sanitary control area  Identify potential contaminant sources within 600 ft of source

7 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 7 Private Water Systems  Individual wells serving one residence  Not subject to State regulations  Regulated at the local level e.g., building permits

8 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Relationship Between Group A’s and Group B’s  Group B and individual wells represent a potential source of contamination for Group A aquifers and should be considered in any protection strategy  Group A source water protection will likely protect some Group B and individual wells 8

9 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Source Water Protection Regulations for Group A systems  Federal: Safe Drinking Water Act  Wellhead Protection Program  1996 amendments - Source Water Assessment Program (SWAP)  State: Chapter WAC  Source approval  Planning 9

10 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 10 Source Water Protection Source Approval  For new Group A sources, both wells and surface water, WAC requires basic source water protection elements for source approval

11 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water 11 Source Water Protection Planning Requirements  Required to prepare:  Water System Plan or  Small Water System Management Program &  Source Water Protection Plan A source water protection plan is either…  included in the WSP or SWSMP  a separate plan

12 Public Health - Always Working for a Safer and Healthier Washington Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Source Water Protection WAC  Groundwater WAC (2&3)  Sanitary control area  Susceptibility assessment  Wellhead protection areas (time of travel zones)  Contaminant inventory  Notification to contaminant source owner/operators, regulatory agencies, and emergency responders  Contingency plan  Update every two years 12
