Phytoremediation—The Natural Pump-and-Treat and Hydraulic Barrier System
(American Society of Civil Engineers, 2000)The use of “water-loving” trees as a supplemental remedy to conventional ground-water “pump-and-treat” systems was employed at a chemical manufacturing site in Texas. The approach entailed taking advantage of the extensive ... -
Nitrogen Mass Balance for Municipal Wastewater
(American Society of Civil Engineers, 2000)Nitrate pollution of ground water is a serious problem in many areas of the United States. One source of nitrate contamination is municipal wastewater effluent. The practice of reusing treated sewage effluent is becoming ... -
Pilot Study Evaluation of Pulsed Plasma Arc Ground-Water Treatment
(American Society of Civil Engineers, 1999)Pilot-scale ground-water treatability studies were performed at the former Nebraska Ordnance Plant site near Mead, Nebr. Ground water at the former Nebraska Ordnance Plant is contaminated by trichloroethene (TCE) and ... -
Remediation of Chromium-Contaminated Soils— Pilot-Scale Investigation
(American Society of Civil Engineers, 2000)This paper describes the results from the pilot-scale demonstration study performed to remediate chromium-contaminated soil by Cold Top ex situ vitrification. Demonstration tests were performed on soils from two sites, ... -
Engineering Reliability Assessment of Contaminant Removal by Pneumatic Fracturing
(American Society of Civil Engineers, 2000)Pneumatic fracturing is a new enhancement process that has been accepted and recognized as a cost-effective technology in removing contaminants from polluted sites. This paper presents an engineering reliability assessment ... -
Effect of SRT on Nutrient Removal in SBR System
(American Society of Civil Engineers, 1999)The effect of solids retention time (SRT) on chemical oxygen demand (COD) degradation and nutrients removal was studied in a sequencing batch reactor (SBR). SRT of 10, 15, 20, 25, and 30 days was studied. A laboratory ... -
Stability of Metal-Arsenic Solids in Drinking Water Systems
(American Society of Civil Engineers, 2000)The solubility of arsenic solids is of importance in public health, water treatment, and geochemistry. This work focuses on copper-arsenic and barium-arsenic solids. Experiments were conducted at conditions typical of water ... -
Effects of Amorphous Iron on Extraction of Lead-Contaminated Soil with EDTA
(American Society of Civil Engineers, 2000)Ethylenediaminetetraacetic acid (EDTA) is one of the more common chelating agents used in the extraction of heavy metals from soil. For soil extraction processes to be economically competitive with other remedial technologies, ... -

Depleted Uranium Disposal Options
(American Society of Civil Engineers, 2000)Depleted uranium hexafluoride (UF -
Recommended Readings for Environmental Site Investigators
(American Society of Civil Engineers, 2000)A large body of literature related to environmental site investigations is described in this article. A narrative describing the type and changing scope of the literature is followed by a bibliography organized into six ... -
Remediation of Chromium-Contaminated Soils: Bench-Scale Investigation
(American Society of Civil Engineers, 1999)A feasibility study was performed to remediate chromium-contaminated soil by cold top ex situ vitrification. This paper describes the initial conceptualization of the research demonstration and the results from the bench-scale ... -
Use of Diesel-Contaminated Soil in Recycled Cold-Mix Pavement
(American Society of Civil Engineers, 1999)The United States military, working with the state and the EPA, combined a contaminated asphalt cement and a reclaimed asphalt pavement (RAP) to produce an asphalt paving material suitable for containing diesel-contaminated ... -
Temperature Properties of Polyester Mortar Using Fly Ash Waste
(American Society of Civil Engineers, 1999)This paper reports on the effect of temperature on the relaxation behavior and the tensile properties (tensile modulus, tensile strength, and ultimate strain) of an unsaturated polyester resin using fly ash waste as a ... -

Development of Background Values for Inorganics in Ground Water
(American Society of Civil Engineers, 1999)Background inorganic concentrations were developed for ground water at the former Naval Construction Battalion Center Davisville, a National Priorities List site, to establish remediation criteria. A multiparty team has ... -
Atrazine Removal through Biofiltration
(American Society of Civil Engineers, 1999)Atrazine is a common contaminant of many surface-water supplies in Missouri and other areas in the midwestern United States. It is classified by the Environmental Protection Agency as a group C–possible human carcinogen, ... -
