Abstract: A flow limiting inlet structure is designed to collect water or other fluids in a pool above grade, and to provide improved capture of sediments and surface pollutants such as oils and greases in the pool, while regulating the flow of water or other fluids during discharge into an outlet pipe. In a conventional storm water detention basin a vertical cylindrical discharge structure can be used to regulate the basin water depth and discharge flow rate of storm water out of the detention basin, in conjunction with the use of a specially designed baffle system that prevents the release of any greases or oils floating on the water surface while capturing any floating trash or debris.

Abstract: The invention provides methods and microbial cultures for the bioremediation of organic halide contaminated groundwater contaminated with organic halides, such as di- and trichloroethene. The methods involve adding, in situ to organic halide-contaminated groundwater a carbohydrate and one or more reductive dehalogenation factors, usually in the form of a nutrient extract, both in amounts sufficient to permit in situ reductive dehalogenation of the organic halide by a microbial population. The microbial population may be endogenous to the ground water or added exogenously. The nutrient-enriched ground water is then maintained in situ under reducing conditions to reductively dehalogenate the contaminating organic halide. Enriched bioremediation cultures are produced by adding to organic halide contaminated groundwater which comprises an endogenous microbial population capable of reductive dehalogenation of the organic halide a carbohydrate and frequently, one or more reductive dehalogenation factors.
