| Abstract |
The document represents a summary of available information and served as a basis for designating the North Florence Dunal Aquifer as a sole source aquifer. The North Florence Dunal Aquifer, located along the south-central Oregon coastline, encompasses the entire continuous body of sand located north of the Siuslaw River and east of the Pacific Ocean. Approximately 8,500 people reside in the 19 square mile area overlying the aquifer; nearly 4,500 within the city of Florence. The aquifer directly supplies about 68 percent of the drinking water consumed in the area. Additionally, the aquifer partly supplies the only surface water source presently used in the area. At this time, the water is of high quality from a human health standpoint. However, rapid infiltration rates into the sand cover combined with a shallow water table make the aquifer highly susceptible to contamination from surface activity. |
