Book Description
This survey report was prepared to assess the role of Corps of Engineers recreation area sewage lagoons in light of recent technology and current and future Corps problems and needs. A review of the literature was conducted to identify design, operation, and upgrading methods that may be applicable to the special loading problems and other circumstances characteristic of recreation area lagoons. Concurrently, a survey was conducted to establish the geographic distribution and the design and performance successes and failures of the more than 200 Corps recreation area lagoons nationwide. Steps are recommended for improving lagoon waste treatment at recreation areas based on current knowledge, and areas of needed research are identified. (Author).

Book Description
The purpose of this study is to develop methods for rapidly and economically increasing the capacity of complete retention and/or intermittently discharging wastewater stabilization lagoons located at Corps of Engineers recreational sites through in situ application of chemical coagulating agents. Alum was chosen as the coagulant in this study because it is relatively inexpensive and readily available. Application and mixing techniques were optimized using a 14-ft boat and small outboard motor. Analyses were performed to determine treatment efficiencies for biochemical oxygen demand (BOD5), chemical oxygen demand (COD), suspended solids, total phosphates and orthophosphates. Algae enumerations were also performed. The study took place over an entire year with three coagulant applications performed to study the long-term effects of in situ alum addition. In situ alum addition consistently produced effluents with phosphate concentrations below 1.0 mg/alum. Removal rates for BOD and COD were approximately 80 percent with suspended solids being removed at rates as high as 95 percent. Algae removal rates were as high as 95 percent. No adverse effects were seen in either lagoon performance or in spraying the effluents on vegetation as a result of alum addition. Sludge accumulations of 0.1 to 0.2 in. per chemical application were measured. Repeated applications of alum did not result in significant increases in the sludge thickness, and no long-term adverse effect on lagoon performance is expected.
