Abstract
An environmental investigation on a 100 ton/day anaerobic digestion plant has been conducted. All input and output streams were analyzed for physical, chemical and microbiological impact. Some mutagenic studies were also conducted. Numerous samples were analyzed over a period of three years for variables of regulatory concern. A few samples were intensively analyzed for trace and ultratrace compounds in the USEPA priority pollutant list. Some batch leaching tests were conducted to estimate the impact of liquid effluents on local soils.
