Water from this reservoir will be used more extensively by the city, so we are developing methods of assessing the water quality in real time by measuring characteristics of stream flow that correlate with important water quality data.
The area contributing recharge to this aquifer is undergoing rapid growth, generating more wastewater. We found that nitrate, a major component of wastewater and a nutrient that can degrade water quality, has increased in the creeks in this area.
Overview of microbiology projects related to water quality investigating bacteria, viral and protozoan pathogens and indicators in the environment with links to publications, analytical and field methods, laboratory, and current projects.
Sulfate deposition to high-elevation areas has decreased here as a result of reductions in SO2 emissions. Nitrate deposition did not change, whereas ammonium deposition increased, particularly at sites near urban and agricultural areas.
