Updated Source Water Assessment Breitenbush Hot Springs PWS #4193461 December 2018 Prepared for: Breitenbush Hot Springs Prepared by: Department of Environmental Quality Agency Headquarters 700 NE Multnomah Street, Suite 600 Kate Brown, Governor Portland, OR 97232 (503) 229-5696 FAX (503) 229-6124 TTY 711 December 20, 2018 Brad Cleary, System Operator Breitenbush Hot Springs PO Box 578 Detroit, OR 97342 Re: Updated Source Water Assessment for PWS # 4193461 Dear Mr. Cleary, On behalf of the Oregon Health Authority (OHA), the Oregon Department of Environmental Quality (DEQ) is pleased to provide your community with important information in this Updated Source Water Assessment. The updated assessment is intended to provide information and resources to assist you and your community to implement local drinking water protection efforts. Since the first source water assessments were completed in 2005, state agencies have significantly expanded analytical capabilities, including more detailed data for analyzing natural characteristics and potential pollutant sources. DEQ is currently completing the updated assessments for surface water systems and OHA is updating the groundwater system assessments. As you know, assuring safe drinking water depends on public water suppliers implementing multiple successful practices. First, protect the drinking water source. Second, practice effective water treatment. Third, conduct regular monitoring for contaminants to assure safety. Fourth, protect the distribution system piping and finished water storage from recontamination. Finally, practice competent water system operation, maintenance, and construction. These practices are collectively called “multiple barrier public health protection”. Source water protection is an important first step because starting with the best possible quality source water helps assure that water treatment can be effective at all times. Source water protection is accomplished by effective state public health programs, environmental protection, land use policies, pro-active land stewardship, and by implementation of local drinking water protection efforts. The susceptibility of the public drinking water system source depends on both the natural conditions in the watershed as well as the anthropogenic activities in the watershed. This letter, with attached figures and technical information, constitutes your Updated Source Water Assessment. It supplements your original Source Water Assessment (link here: http://www.deq.state.or.us/wq/dwp/swrpts.asp ). One of the most important assets a public water system can have is accurate source water area mapping and visual resources to share with the community citizens and officials. The figures include a new regional map view of your watershed, topographic basemap with the source area delineated, and maps with natural characteristics, anthropogenic land uses, potential sources of pollutants, and historic landslides. Information on anthropogenic land uses in a drinking water source area is important for evaluating potential pollutant sources and working with stakeholders upstream. Tables are provided that include a summary of the types of potential pollutant sources present in your drinking water source area. There are also a variety of resources included in this document to assist you with drinking water source protection efforts. Appendix #1 provides a summary of how to use the information provided in the assessment to move forward to develop and implement source water protection. Appendix #3 lists websites and resources available to public water systems and community members seeking technical assistance for work on watershed protection. Appendix #4 provides brief descriptions and contact information for grants and loans to fund both drinking water infrastructure and source protection projects. State agency resources are available to help you with mapping and information needs. Larger sizes of the source area maps and more details of landslide potential and other natural characteristics are available for you upon request (contact Julie Harvey at 503-229-5664). DEQ is currently developing “Resource Guides” with more extensive information to assist public water systems in protecting their source waters. The Surface Water Resource Guide is posted at http://www.oregon.gov/deq/wq/programs/Pages/dwp.aspx. For direct assistance and/or additional information regarding watershed protection, call Julie Harvey at DEQ (503-229-5664). For more information on drinking water policies and procedures, call Casey Lyon at OHA (541-726-2587).
