The objectives were to define basic waste characteristics from recreation areas, evaluate existing treatment processes and to develop a guide for the planning and design of wastewater treatment facilities at recreation areas. The two winter recreation areas included Timberline Lodge on Mt. Hood, approximately 50 miles east of Portland, Oregon, and Crystal Mountain Ski Area near Mt. Rainier National Park, approximately 50 miles east of Tacoma, Washington. The two summer areas included Sunset Bay State Park, also on the Oregon coast, approximately five miles north of Bandon. The problems of designing these systems is discussed. Such factors as variations in pH ad flow present design difficulties. (Author)
