Contents Notes
"Operational characteristics and overall acceptability were determined for popular models of biological toilets and a few select grey water systems. A field observation scheme was devised to take advantage of in-use sites throughout the State of California. Field performance was recorded monthly on forms developed to record site conditions such as pile temperatures, odors, and vector observations. Samples of the decomposition chamber pile and the end products were taken for laboratory analyses that included both physical and microbiological parameters. Grey water influent and effluent were also analyzed. A health risk assessment was performed concurrently using environmental health experts to estimate the probability of a significant failure for a particular onsite waste treatment and disposal system. The health experts used an objective decision-making technique that may be used by regulatory officials to evaluate new technologies where there is an absence of definitive test information. This assessment results in a probability that is expressed in relation to the estimated risk of a known system, the septic tank/soil absorption system. Model frameworks for education and surveillance monitoring are presented. Since the user may need guidance during siting and operation and in the event of system failures, third-party management is strongly advised."
