Hydrograph Decomposition: Using a Technical Database
Trouble shooting for infiltration/inflow (I/I) problems in a sewer system is made much easier with the aid of a computerized hydrograph decomposition methodology. A methodology has been...

Conjunctive Use/Sustained Groundwater Yield Design
Assuring the sustained availability of groundwater from all parts of an aquifer system is analagous to assuring that the potentiometric surface does not change over the long term. Such...

Regional Target Level Modification for Groundwater Quality
A procedure for modifying an optimal regional potentiometric surface designed solely on the basis of quantitative considerations, is described. These modifications are based on quality...

Well Rehabilitation Using Decision Tree Analysis
The decision tree concept of decision analysis theory can be easily adapted to the water and wastewater industry in making spending decisions for rehabilitation programs, renewal and replacement...

Predicting Areas of Groundwater Contamination
Logistic regression has been used to estimate the probability that a metropolitan area will contain one or more water supply sites with contamination by one or more of six frequently occurring...

Development of a Demand Management Plan for Greater Boston
The Metropolitan District Commission (MDC) in Boston is preparing a long-term water supply plan for its present and potential service area. The MDC is committed to a program of water conservation...

Prototype Laser Fluorescence/Fiber Optics Groundwater Contaminant Detector
Laboratory testing of a prototype field-portable instrument for in-situ laser fluorescence analysis of groundwater contaminants using fiber optics is discussed. Gasoline, gasoline components,...

Nitrate Analysis Utilizing Groundwater Modeling
Groundwater is the sole source of potable water for the Town of Barnstable, Massachusetts. It is, therefore, of paramount importance to maintain the overall quality within acceptable drinking...

Ground Water Quality Assessment Using Unsaturated and Saturated Zone Models
The modeling work described here provides an assessment of the migration and fate of the pesticide aldicarb in typical Florida citrus applications with emphasis on the potential for leaching...

A Case Study of Ground Water Quality Protection in California
Incidents of ground water contamination from improper disposal of industrial wastewater have been widespread throughout California. In late 1984 the State Water Resources Control Board...

Modeling Aromatic Compound Transport in Groundwater
Research results are presented from an ongoing study directed at obtaining a better understanding of the factors affecting the binding characteristics of organic chemicals to ground water...

Groundwater Studies for Land Treatment Facility
A wastewater treatment facility currently under construction in Falmouth, Massachusetts, features a dual disposal method for land application of effluent. As the effluent disposal site...

Potential for Nitrate Removal from Groundwater Supplies Using Biological Deintrification
Nitrate concentrations in groundwater supplies have been increasing over the years throughout many areas in the U. S. to the point of posing potential health dangers to a multitude of...

Simplified Methods to Predict the Fate of Metals in Rives
Heavy metal contamination of rivers is of increasing concern to society. To help predict the fate of metals in rivers, researchers have developed computer models to simulate speciation...

Direct Filtration of Colored Water Supplies
The effects of raw water quality, chemical treatment, and filtration variables on the performance of direct filtration are examined. Cationic polyelectrolytes as sole coagulants are effective...

Maintenance Management for a Large Urban Waterworks System
The Boston Water and Sewer Commission (BWSC) owns and operates a water distribution system consisting of 86,000 customer accounts and 1,100 miles of water mains. In 1984, BWSC initiated...

Relating Water Treatment Problems to O & M Factors
The author discusses the operations and maintenance factors that must be considered in dealing with water treatment problems....

Environmental Infrastructure: Does Civil Engineering Education Meet the Challenge?
The author explores some avenues for re-direction of the civil engineering education process to become more responsive to the needs of infrastructure re-development in the areas of water...

Microcomputer Methods for Toxicants in Ground Waters and Rivers
This paper describes a program written for the IBM personal computers to assess the fate of toxicants in ground waters and in rivers. The algorithms in the program were selected from a...

Underground Oil Lens Management at John F. Kennedy International Airport
Observation wells plumbed using a water surface detector and standard topographic interpolation techniques were used to establish the hydraulic gradient of the groundwater and the presence...
