Engineering Aspects of Point Versus Nonpoint Sources of Groundwater Pollution
Pollution of groundwater may occur due to a number of sources. These may be categorized into point and nonpoint sources of contamination. The purpose of this paper is to explore the issues...
Survey of Groundwater Contamination in Massachusetts
Public water supplies in Massachusetts have been contaminated or threatened from a number of sources. The purpose of this paper is to outline the nature of groundwater contamination and...
Synthetic Organic Contaminants and Pesticides in Groundwater
For decades, the groundwater of Suffolk County, New York, has been bacteriologically and chemically of superior quality despite the high iron and manganese occasionally encountered in...
Technical Issues of Ground Water Data
Three fundamental issues to be considered in the design of ground water monitoring programs are 1) choice of parameters for characterizing contaminant sources, 2) determining the areal...
Managing Ground Water Data
Decisions concerning ground water protection and public health should be based on all relevant data, measured and analyzed with technically valid techniques. In areas where ground water...
Some Problems in the Engineering of Ground Water Cleanup
The problems facing engineers, often civil engineers, in addressing ground water contamination are both exotic and mundane, but all are critical to success. The paper provides a brief...
Control of Groundwater Contamination: Case Studies
Engineered solutions to groundwater contamination problems are being proposed at many hazardous waste sites, yet the effectiveness and long-term reliability of many of these proposed solutions...
Best Management Practices for Point and Nonpoint Sources of Groundwater Contamination
Management strategies have included regulations to guide or limit development in aquifer recharge areas and in the capture zones of public wellfields, engineering requirements to minimize...
The Delineation and Management of Wellhead Protection Areas
The delineation and protection of a management zone around specific wells or wellfields will undoubtedly become more common as the 1986 Amendments to the Safe Drinking Water Act are implemented...
Biological Treatment of Trichloroethylene
Trichloroethylene and related compounds such as cis- and trans-1,2-dichloroethylene and vinyl chloride are common contaminants of ground water in industrial areas. In oxygenated ground...
Physical and Chemical Treatment of Contaminated Groundwater at Hazardous Waste Sites
In selecting an appropriate groundwater treatment system, three steps are normally followed. 1. A groundwater investigation is performed to determine the types and concentrations of contaminants...
The Impacts of CERCLA, RCRA and State Programs on Site Remediation: A Case Study
The major federal programs requiring ground water remedial response actions include RCRA and CERCLA. On the state level New Jersey law makers have enacted a number of statutes which regulate...
Agriculture or Industry? Greenhouse Development in Carpinteria, California
During the past decade, Santa Barbara County, California has witnessed the rapid conversion of orchard and open field agriculture in the Carpinteria Valley to large commercial greenhouse...
Coastal Groundwater Outflow: Solution to a Dynamic Problem
The pattern of fresh groundwater outflow at the coastal margin of a phreatic aquifer can be approximated by a quasi-transient analytical model. The suggested procedure includes transformation...
Movement of Nonaqueous Liquids in Groundwater
Evidence from field sites indicates that when nonaqueous liquids, such as organic solvents and gasoline, are released into the subsurface environment they tend to remain as a separate...
Containment of Low-Level Radioactive Material
The U. S. Department of Energy has completed a short term storage site for the containment of low-level radioactive residues and contaminated soil near Lewiston, New York. The site, known...
Waste Concentration Effects of Grout Barriers
Great concern has developed over hazardous waste sites, particularly in the leaching of the hazardous wastes into groundwater supplies. Many sites that are considered contaminated and...
Flow and Mass Transport for Hazardous Waste Liners
Certain aspects of flow and contaminant migration of hazardous liquids through soils are addressed. A fine-grained soil and fluids commonly encountered in hazardous sites, were considered....
Hydrogeologic Investigations at a Superfund Site in Wisconsin
An estimated 10,000 drums of volatile organic wastes from a nearby manufacturing plant were dumped at a landfill site in southern Wisconsin. Chemicals released from these drums have contaminated...
Conversion of a Reservoir Into a Landfill Site
The Writer is acting as a geotechnical consultant during the conversion of a disused water reservoir into a landfill site for domestic and industrial refuse. The site developer had no...
