Wastewater Treatment Systems for Safety Rest Areas

Intra Government Purchase Order No. 4-1-0188Design guidelines for rest-area wastewater treatment systems that are capable of complying with the requirements of PL 92-500 are presented. Also presented is guidance for determining wastewater flow and constituent concentration. Each wastewater treatment system presented (septic tanks, lagoons, extended aeration package plants, trickling filters, rotating biological filters, land treatment systems, intermittent sand filter systems, and disinfection) includes a process description, a discussion of the performance, flexibility, reliability, and operational procedures, preliminary design formulations, and references and selected bibliography. Also included is a flow chart showing a general design procedure for new and existing rest areas with emphasis on water supply needs and wastewater treatment systems

Physical and chemical characteristics of the Yaquina Estuary, Oregon

"After a brief description of the setting of the Yaquina Estuary, estuarine dynamics and classification, and estuarine chemistry are presented. Then, temperature-salinity relations are reviewed using the Rattray-Officer model in simulating variable distributions reported by Callaway and Specht (1982) and Callaway (1991). Finally, the numerical models DynHyd and WASP are reviewed, some out put for each model are shown and the results discussed." (from the Introduction
