Wellhead Protection Area Predictions and Implications for the Biscayne Aquifer in Miami, Florida
The need to protect groundwater supplies from sources of contamination is of particular relevance to densely populated urban areas, such as Dade County (Greater Miami), in South Florida....
Juvenile Fish Separator Design
Separation by size of downstream migrant juvenile salmonids at hydroelectric projects in the Columbia River basin is an integral part of transportation and bypass programs. However, separation...
Effect of Surface Water and Ground Water Interaction on Atrazine Transport to Pumping Wells
High concentrations of agricultural chemicals in flood waters have been reported in many Midwestern rivers and streams. The public water supply wells of a number of riparian communities...
Use of Artificial Neural Networks for Agricultural Chemical Assessment of Rural Private Wells
The detection of agricultural chemicals in rural private wells has prompted for numerous studies at regional, state, and national levels. A principal concern arises from the fact that...
Simulation of Unsaturated Zone Virus Transport Adjacent to Municipal Wells
The EPA proposed groundwater disinfection rule for municipal wells would allow exemptions if, among other options, the necessary virus source setback distance could be maintained to provide...
Beneficial Aspects of Flood and Rain in Countries Where the Drinking Water is Naturally Contaminated with Fluoride Where Fluorosis is a Major Public Health Problem
Floods, although considered destructive, have beneficial aspects too. This report is about one such instance where flood waters are considered extremely beneficial in countries where drinking...
Effects of Ignoring Well Losses on the Specific Capacity Function
This paper combines these equations with the traditional step-drawdown equation to generate a more realistic relationship among discharge, specific capacity, and drawdown. Under both confined...
Conjunctive Water Use Transforms a California Desert
An area doing multi-billion dollar recreational and agricultural business in the Southern California Sonoran desert owes its existence and well being to two things?wise water planning...
Use of ??8O and ?D to Define Seawater Intrusion
On the basis of previous studies, more than 60 km? of upper aquifer system underlying the Oxnard Plain was believed to be intruded by seawater. Recent work has shown that there are sources...
Economic Impact of Managing Sea Water Intrusion
Sea water intrusion into a coastal aquifer may result from continued over extraction of the aquifer. In many coastal communities, sea water intrusion has led to artificial recharge programs...
Operation and Maintenance of Ground Water Facilities
The objective of this manual,
Mapping History
Difficult, environmentally sensitive terrain combined with the fact that Canadian Western Natural Gas's new Banff pipeline will be laid in archaeologically rich ground posed a challenge...
Water Quality Regs: Staying Ahead
After a century in which water utilities could stay well ahead of most regulations simply by being responsible, professional organizations, they now seem to be playing catchup in a game...
Columbus Clear Wells
At an average of 8 million gal. each, six new clear wells at the Hap Cremean Water Plant in Columbus, Ohio represent the largest post-tensioned, reinforced concrete noncircular tanks ever...
Bioremediation Comes of Age
Only five years ago engineers and scientists met with EPA officials to weigh the merits of bioremediation as a hazwaste cleanup tool. Now bioremediation has become an accepted effective...
Lunar ISRU: An Evolutionary Approach
The goal of this paper is to provide the reader with a vision of the individual steps required to bring ISRU from the current technological readiness level of lab experimentation, to large...
Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...
Rehabbing for Remediation
Workers for Moses Lake detected trichloroethylene (TCE) in three of the city's water wells. The concentrations were low, around 5 to 15 parts per billion, just above the maximum...
Buoy Directional Wave Measurements Using Magnetic Field Components
Directional wave data can be estimated using the heave, pitch and roll motion of a discus buoy, which are conventionally measured by a pitch-roll sensor. To reduce the size and cost, this...
A Method for Locating Spikes in a Measured Time Series
Raw directional wave sample time series are frequently contaminated with spikes from various sources. The standard procedure in correctly editing these time series includes locating and...
