Bioremediation Of Contaminated Surface Soils, J. L. Sims, R. C. Sims, J. E. Matthews
Bioremediation Of Contaminated Surface Soils, J. L. Sims, R. C. Sims, J. E. Matthews
Reports
Biological remediation of soils contaminated with organic chemicals is an alternative treatment technology that can often meet the goal of achieving a permanent clean-up remedy at hazardous waste sites, as encouraged by the U.S. Environmental Protection Agency (U.S. EPA) for implementation of The Superfund Amendments and Authorization Act (SARA) of 1986. Bioremediation is consistent with the philosophical thrust of SARA, for it involves the use of naturally occurring microorganisms to degrade and/or detoxify hazardous constituents in the soil at a contaminated slip to protect public health and the environment.Bioremediation of contaminated soils, including applications and limitations, has been addressed.

Introduction: The application of mulch during or immediately following seeding provides the minimum following advantages: energy dissipation of falling raindrops which decreases or eliminates erosion, prevention of surface-soil crusting, decreased water loss, and surface temperature modification. To better hold mulch in place, chemical binders are addd to it during munufacture or just before it is applied to the soil. Sometimes a binder is applied as an oversptray after the mulch is in place. (This overspray is generally referred to as a tackifier.) Algea Produkter A/S, Drammen, Norway, produces a product called ALGROW which may habe utility as a mulch binder …

Toxicity And Environmental Health Hazards Of Petroleum Products In Wells Used For Drinking Water In The Intermountain West, Robert D.R. Parker, Raghubir P. Sharma, R. Ryan Dupont, Gin-Chang Hsieh
Reports
Introduction: Groundwater is aprimary source of drinking water for about 50 percent of the population in the U.S. This source of drinking water has been generally regarded as safe from contamination. Several papers indicate that numerous underground storage tanks containing petroleum products may be leaking and contaminating public water supply wells across the U.S. (Matis, 1971; Ferguson, 1979; Woodhull, 1981; Burmaster and Harris, 1982; Lehman, 1984; Dowd, 1984; OTA, 1984). A study conducted by the Utah Cureau of Solid and Hazardous Wastes in 1985 concluded that there are at least 2,314 underground steel tanks, most of which are used to …

Soil Phase Photodegradation Of Toxic Organics At Contaminated Disposal Sites For Soil Renovation And Groundwater Quality Protection, W. M. Moore, R. Ryan Dupont, J. E. Mclean
Soil Phase Photodegradation Of Toxic Organics At Contaminated Disposal Sites For Soil Renovation And Groundwater Quality Protection, W. M. Moore, R. Ryan Dupont, J. E. Mclean
Reports
Accurate assessment of the potential for contaminated soil remediation requires detailed knowledge of the fate of waste constituents within the soil environment. For many non-biodegradable organics compounds, photochemical degradation may provide a potential pathway for the removal of such compounds from soil surfaces. A study was conducted to evaluate the rate of photodegradation of ten hazardous organic compounds from three soils, silica gel, and four soil minerals (kaolinite, montmorillonite, illite, and calcite) under conditions of controlled irradiation. In addition, the effect of siz amendment treatments (methylene blue, riboflavin, hydrogen peroxide, diethylamine, peat moss, and silica gel) on the rates of …
