Biotransformations Under Denitrifying Conditions

Risk of Waterborne Infectious Illness Associated with Diving in the Point Loma Kelp Beds, San Diego, CA
There is considerable interest in estimating the risk of bacterial and viral illness (i.e., disease, infection) associated with scuba diving in the Point Loma kelp beds located within...

Fate and Effect of Carbon Tetrochloride and O-Xylene on Anaerobic Systems with Sulfate Reducing Bacteria
The fate and effects of o-xylene and carbon tetrachloride on methanogens and sulfate reducing bacteria were investigated using serum bottles. Up to 750 mg/1 of o-xylene did not cause any...

Anaerobic Biological Reduction of Selenate
When soils with high concentrations of naturally-occuring selenium are irrigated and drained, selenium is leached from the soil and appears in the drainage water. Selenium has caused death...

Research Needs Concerning Biological Agents in the Marine Environment

Health Effects of Ground Water Recharge
A five year multidisciplinary research project was conducted to evaluate the health significance of using treated wastewater for ground water replenishment. The focus of the study was...

Bacterial Fingerprinting to Trace Source of Coliform Bacteria During Artificial Recharge
This report describes the use of a bacterial 'fingerprint' technique to determine if treated effluent from infiltration beds was the source of coliform bacteria...

Is It Safe to Eat the Seafood?
The issue of bacterial, viral and chemical contamination of Puget Sound seafood and its consequent impact on human health has been of concern for some time. This paper discusses potential...

Nitrification in a Salt Wedge Estuary
Autotrophic nitrifying bacterial activity and numbers were measured in a salt wedge estuary receiving ammonium-rich effluent from a municipal secondary wastewater treatment facility. Instream...

Monitoring for Indicator Bacteria in Small Water Systems

Strategy to Improve Drinking Water Quality in Small Water Systems in Puerto Rico

Field Study of Specialized Bacteria for Nitrification
A full scale field study using specialized bacteria was conducted to determine its effectiveness in achieving nitrification while quantifying dosage rates. A side-by-side comparison of...

Low Head Filtration Removal Efficiencies of Giardia Cysts, Coliform Bacteria, and Turbidity From Low Turbidity Water
The removal of Giardia cysts from low turbidity waters is of great concern in many areas of the United States. A pilot program was undertaken to determine if an established low head filtration...

Leaching Characteristics of Metal Finishing Sludges
The purpose of this research was to study the feasibility of biodegrading phenolics to methane by thermophilic anaerobic treatment. The study was a feasibility level assessment which examined...
