Monitoring Water Quality and Use in Colorado
This paper presents the results of a two year study on the impact of irrigation water use on water quality near Greeley, CO. Data on irrigation application efficiency, deep percolation,...
Statewide Consumptive Use Estimates
Methodology for estimating consumptive use and consumptive irrigation requirements on a statewide basis is summarized. The methodolgy has been used to update monthly and seasonal consumptive...
Surface Water Withdrawal Permits Programs for Humid Regions
In humid regions of the U.S., where control of surface water withdrawal is traditionally under the riparian doctrine, there are few strong regulatory programs to restrict water use. In...
Wetland Loss Rates and Agricultural Drainage
The current paper uses National Resources Inventory data to document the relation between private on-farm agricultural drainage investment activity and wetlands loss. The paper presents...
Surface Water Quality Modeling in the Rio Grande
The City of Albuquerque (City) in New Mexico owns and operates the Southside Water Reclamation Plant (SWRP), which discharges an average of 200623 m3/d...
Wastewater Reclamation at Davenport, Washington
The City of Davenport, Washington went through an extended process to update their undersized wastewater treatment and irrigation reclamation systems for municipal wastewater. The process...
Recommendations for Standards in Hydraulics
Prepared by the Task Committee on Recommendations for Standards in Hydraulics of the Hydraulics Division of ASCE. This report investigates whether...
Application of a Geographic Information System to Evaluate Environmental Hazards
The development of a Geographic Information System (GIS) application to evaluate potential environmental hazards within the Bushkill watershed in Northampton County, Pennsylvania, is described...
Water Infrastructure Risk Ranking and Filtering Method
The availability of water distribution infrastructure is critical to the sustained support and growth of society. Water infrastructure consists of systems that carry water (pipe and irrigation...
Environment-Irrigation Trade-Offs and Risks
Allocation of scarce water resources between environmental and commercial uses is an extremely important problem in many parts of the world. A study is under way in Australia to examine...
Treatment of Oil in Water Emulsions by Ceramic-Supported Polymeric Membranes
A novel membrane was developed by growing polymer chains from the surface of a porous ceramic support, resulting in a composite membrane which combines the mechanical properties of the...
Assessing Roughing Filtration Design Variables
Rural communities are affected by the surface water treatment rule and are looking for inexpensive filtration options which are easy to operate and maintain. This paper evaluates roughing...
Biodegradation of Phenanthrene in Sand Columns in the Presence of Nonionic Surfactants
The effects of three nonionic surfactants on phenanthrene (C14H10) removal and mineralization by aerobic bacteria...
Artificial Recharge of Aquifers
Artificial groundwater recharge is a means of replenishing groundwater supplies with surface water which might otherwise be lost. Artificial groundwater recharge has also been used to...
Ozonation as an Alternative to Mandatory Filtration
The increased levels of required disinfection along with more stringent disinfection by product control as outlined in the Surface Water Treatment Rule and the Disinfectant-Disinfection...
Treatment of Drinking Water Containing Bromate and Bromide Ions
Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate...
A Gap in the Surface Water Treatment Rule: The Watersheds
Watershed control is required by the Surface Water Treatment Rule of the 1986 Amendments to the Safe Drinking Water Act for systems that do not provide filtration. Where filtration is...
Activated Carbon as a Catalyst for Polymerization of Phenolic Compounds
Previous studies by the principal investigator showed that the increase in the adsorptive capacity of activated carbon for phenolic compounds can be attributed to polymerization (oxidative...
Predicting the Impact from Significant Storm Events on a Hazardous Waste Site
The Stringfellow Hazardous Waste Site is a former Class I industrial waste disposal facility located near the community of Glen Avon in southern California. In response to community concerns...
A New Set of Equations for Very Shallow Water and Partially Dry Areas Suitable to 2D Numerical Models
When a 2D model is used to compute the flood propagation over an initially dry area some difficulties arise due to the changes in the computational domain as large parts of it are flooded...
