1 SOURCE WATER ASSESSMENT SUMMARY BROCHURE PP&L TOKETEE VILLAGE PWS # WHAT IS A SOURCE WATER ASSESSMENT? The Source Water Assessment was recently completed by the Department of Environmental Quality (DEQ) and the Oregon Health Division (OHD) to identify the surface areas (and/or subsurface areas) that supply water to PP&L Toketee Village s public water system intake and to inventory the potential contaminant sources that may impact the water supply. WHY WAS IT COMPLETED? The Source Water Assessment was completed to provide information so that PP&L Toketee Village s public water system staff/operator, consumers, and community citizens can begin developing strategies to protect the source of their drinking water, and to minimize future public expenditures for drinking water treatment. The assessment was prepared under the requirements and guidelines of the Federal Safe Drinking Water Act (SDWA). WHAT AREAS ARE INCLUDED IN PP&L TOKETEE VILLAGE S DRINKING WATER PROTECTION AREA? The drinking water for PP&L Toketee Village is supplied by an intake on Toketee Lake. This public water system serves approximately 25 citizens. The intake is located in the Fish Creek Watershed in the North Umpqua Sub-Basin of the Southern Oregon Coastal Basin. The geographic area providing water to PP&L Toketee Village s intake (the drinking water protection area) extends upstream approximately 0.12 stream miles and includes 84 acres of lakes. The protection area encompasses a total area of 351 square miles. The boundaries of the Drinking Water Protection Area are illustrated on the figure attached to this summary. There are three drinking water intakes on the North Umpqua River downstream of the PP&L Toketee Village intake including the intakes for the Glide, Roseburg and the Umpqua Basin Water Association. Activities and impacts in the Toketee Village drinking water protection area have the potential to also impact downstream users. WHAT ARE THE POTENTIAL SOURCES OF CONTAMINATION TO PP&L TOKETEE VILLAGE S PUBLIC DRINKING WATER SUPPLY? The primary intent of this inventory was to identify and locate significant potential sources of contaminants of concern. The delineated drinking water protection area is primarily dominated by managed forestlands. The potential contaminant sources identified in the watershed include Diamond Lake Resort, Lemolo Lake Resort, Toketee Campground, clear cut forestlands, road density, upstream dams/reservoirs, stream crossings, Toketee Ranger Station, Clearwater Village, Pacific Power & Light Control Center, Pacific Power and Light Hydro Project, two transportation corridors, areas of high density housing, and a transfer station. This provides a quick look at the existing potential sources of contamination that could, if improperly managed or released, impact the water quality in the watershed. WHAT ARE THE RISKS FOR OUR SYSTEM? A total of fifteen (15) potential contaminant sources were identified in PP&L Toketee Village s drinking water protection area. All of these are located in the sensitive areas and are high- to moderate-risk sources within sensitive areas. The sensitive areas within the PP&L Toketee Village drinking water protection area include areas with high soil permeability, high soil erosion potential, high runoff potential and areas within 1000 from the river/streams. The sensitive areas are those where the potential contamination sources, if present, have a greater potential to impact the water supply. The information in this assessment provides a basis for prioritizing areas in and around our community that are most vulnerable to potential impacts and can be used by the PP&L Toketee Village community to develop a voluntary Drinking Water Protection Plan. NEED MORE INFORMATION? PP&L Toketee Village s Source Water Assessment Report provides additional details on the methodology and results of this assessment. The full report is available for review at: Contact PP&L Toketee Village staff if you would like additional information on these Source Water Assessment results.
