SOURCE WATER ASSESSMENT SUMMARY BROCHURE

CITY OF ROGUE RIVER

PWS # 4100712 WHAT IS A SOURCE WATER ASSESSMENT? The Source Water Assessment was recently completed by the Department of Environmental Quality (DEQ) and the Oregon Department of Human Services (DHS) to identify the surface areas (and/or subsurface areas) that supply water to City of Rogue River’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 Rogue River’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 ROGUE RIVER’S DRINKING WATER PROTECTION AREA? The drinking water for the City of Rogue River is supplied by an intake on the Rogue River. This public water system serves approximately 2,000 citizens. The intake is located in the Rogue River/Savage Creek/Evans Creek Watershed in the Middle Rogue Subbasin of the Southern Oregon Coastal Basin. In addition, Rogue River uses groundwater wells for drinking water supply. The Source Water Assessment addresses only the surface water component of Rogue River’s drinking water supply. The groundwater supply will be addressed separately.

The drinking water intakes for the City of Gold Hill, Medford Water Commission, Country View Mobile Home Estates, and Ashland Water Department public water systems are also located on the Rogue River (or its tributaries) upstream of the City of Rogue River intake. The boundaries of Rogue River’s portion of the Drinking Water Protection Area (the area between Rogue River’s intake and Gold Hill’s intake) and a schematic of the portions of the protection area upstream of the Gold Hill intake are illustrated on the figures attached to this summary. In addition, the City of Grants Pass has a drinking water intake on the Rogue River downstream of City of Rogue River’s intake. Activities and impacts in the Rogue River drinking water protection area have the potential to also impact downstream users. We encourage other water providers in the Subbasin to work together as you move forward with developing a protection plan or strategies for your drinking water supply. The geographic area providing water to Rogue River’s intake (Rogue River’s portion of the drinking water protection area) extends upstream approximately 119 miles (2,492 stream miles including the area upstream of the Gold Hill intake) and encompasses a total area of 107 square miles (total of 2,187 square miles including the area upstream of the Gold Hill intake). Included in the Rogue River portion of the delineation are a number of tributaries to the Rogue River, including Ward, Foots, Galls, Sardine, and Kane Creeks. The protection area within an 8-hour travel time from the intake extends approximately 16 miles upstream of the Rogue River intake. It is recommended that the water systems and community consider increased protection within an 8-hour travel time from the intake since eight hours should provide adequate response time to protect the integrity of the public water system intake should a spill or release occur at any crossing or discharge point to the stream. The Rogue River intake is located at an approximate elevation of 1,000 feet and the upper edge of the watershed is located at an elevation of approximately 4,494 feet at Mt. Isabelle.

WHAT ARE THE POTENTIAL SOURCES OF CONTAMINATION TO ROGUE RIVER’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 residential and agricultural land uses. The potential contaminant sources identified in the Rogue River’s portion of the protection area include four transportation corridors, sewer lines, high density housing, rural homesteads, grazing animals, non-irrigated crops, irrigated crops, forest harvest units, two automobile repair shops, a shopping mall, a wood products mill, wastewater treatment plant, two water treatment plant, gravel pit, fire station, two metal fabrication companies, and one state park. The potential contaminant sources within the drinking water protection area all pose a relatively higher to moderate risk to the drinking water supply with the exception of non-irrigated crops, storage units and the fire station, which presents a lower risk. 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 30 potential contamination sources were identified within the Rogue River portion of the drinking water protection area. An additional 254 potential sources were identified upstream of the Gold Hill intake. Of the 30 potential sources identified in Rogue River’s portion of the protection area, 28 are located in the sensitive areas and 25 are high- to moderate-risk sources within “sensitive areas”. The sensitive areas within the City of Rogue River 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 City of Rogue River community to develop a voluntary Drinking Water Protection Plan. NEED MORE INFORMATION? City of Rogue River’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 of Rogue River’s staff if you would like additional information on these Source Water Assessment results.
