摘要

Studies resulting in high water quality of the Houghton Lake Wetland Treatment system are reported. This system successfully treated 65 million gallons of secondary wastewater in the summer of 1978 for use in irrigating the Porter Ranch wetland in Michigan. Field research at the wetland focused on: (1) Collection of data to establish a current picture of the ecosystem in the discharge area; (2) continuous monitoring of the response of the irrigation area to wastewater flow; and (3) continuation of fundamental field studies to better understand response mechanisms and wetland system limits. Specific aspects described include water chemistry, soil elevation and sampling, vegetation analysis, algae studies, nutrient sorption, bacteria and virus assays, and census of vertebrates and invertebrates. Laboratory studies were conducted to measure the rates and extent of physiochemical sorption of ammonia, nitrate, and phosphate.
