1 SOURCE WATER ASSESSMENT SUMMARY BROCHURE CITY OF ROSEBURG 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 City of Roseburg s public water system intake and to inventory the potential contaminant sources that may impact the water WHY WAS IT COMPLETED? The Source Water Assessment was completed to provide information so that City of Roseburg 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 CITY OF ROSEBURG S DRINKING WATER PROTECTION AREA? The drinking water for City of Roseburg is supplied by an intake located near Winchester on the North Umpqua River. This public water system serves approximately 30,000 citizens. The intake is located in the Lower North Umpqua River/Little River Watershed in the North Umpqua Sub-Basin of the Southern Oregon Coastal Basin. The drinking water intake for Glide Water Association (City of Glide), the PP&L Toketee Village, and USFS Wolf Creek Job Corps public water systems are also located on the North Umpqua River or the Little River upstream of the Roseburg intake. This source water assessment addresses the geographic area providing water to Roseburg s intake (Roseburg s portion of the drinking water protection area) between Roseburg s intake and the upstream intake for Glide and USFS Wolf Creek Job Corps. Information on the Roseburg s protection area upstream of these intakes is summarized in the Roseburg Source Water Assessment. In addition, there is one drinking water intake (for the Umpqua Basin Water Association) on the North Umpqua River downstream of Roseburg s intake. Activities and impacts in the Roseburg, Glide, Toketee Village, and Wolf Creek Job Corps drinking water protection area have the potential to also impact downstream users. A schematic figure showing the drinking water intakes and protection areas within the North Umpqua Sub- Basin is provided in this summary brochure. The geographic area providing water to Roseburg s portion of the drinking water protection area extends upstream approximately miles in an easterly direction and encompasses a total area of square miles. Included in this area are a number of tributaries to the main stem, including Cooper, Huntley, Dixon, Clover, Oak, Buckhorn Creeks and the Little River and its tributaries. The boundaries of the Drinking Water Protection Area are illustrated on the figure attached to this summary. WHAT ARE THE POTENTIAL SOURCES OF CONTAMINATION TO CITY OF ROSEBURG 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 dominated by commercial, residential/municipal, and agricultural land uses. The potential contaminant sources identified in the watershed that relate to commercial land uses include an electronics manufacturer, a metal fabrication company, a bathroom manufacturer, a trucking company, two gas stations, and an auto repair shop. The potential contaminant sources within the drinking water protection area that are related to residential/municipal land uses include six schools, a wastewater treatment plant, two water treatment plants, a transfer station, parks, a fire station, a substation, three transportation corridors, and a ranger station. The potential contaminant sources within the drinking water protection area that are related to agricultural land uses include grazing animals, irrigated

2 crops, and clear-cuts. In addition an industrial area located just outside the drinking water protection and north of the intake was included in this inventory because of the potential risk to the drinking water. This provides a 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 twenty-nine (29) potential contaminant sources were identified in City of Roseburg s drinking water protection area. Twenty-seven (27) of these are located in the sensitive areas and are high- to moderate-risk sources within sensitive areas. The sensitive areas within the City of Roseburg portion of the 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 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 City of Roseburg community to develop a voluntary Drinking Water Protection Plan. NEED MORE INFORMATION? City of Roseburg 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 the City Public Works staff if you would like additional information on City of Roseburg s Source Water Assessment results.
