Gabor , Rachel 1 ; McKnight , Diane 2 1 University of Colorado-Â鶹ӰԺ 2 University of Colorado-Â鶹ӰԺ The increasing concentrations of dissolved organic matter observed in many northern latitude regions have potentially significant effects on both ecosystem dynamics and water treatment processes. Many hypotheses for the cause of this change...

Ebert , Jessica L 1 ; Driscoll , Charles T 2 1 University of Colorado at Â鶹ӰԺ 2 Syracuse University Urban stormwater runoff is a critical water quality problem for older cities in the Northeast, including Syracuse NY. In this study we examined the response of Onondaga Creek to high...

Dittrich , Timothy M 1 ; Ryan , Joseph N 2 1 University of Colorado-Â鶹ӰԺ 2 University of Colorado-Â鶹ӰԺ The presence of small particles (colloids) in natural soil and groundwater systems has been well established. Under certain environmental conditions, the sorption of contaminants to mobile colloids can increase transport in...

Cullis , James D 1 1 Civil Environmental and Architectural Engineering (CEAE) and Institute for Arctic and Alpine Research (INSTAAR) Didymosphenia geminata (didymo) was introduced into a New Zealand river in 2004, and since then has dramatically spread to cover the beds of many rivers with extremely dense and extensive...

Casetllani , Benjamin B 1 1 Univeristy of Colorado at Â鶹ӰԺ As a result of increasing anthropogenic emissions of pollutants, tropospheric ozone levels are projected to rise 40 to 60 percent by the year 2100 (IPCC 2007). This study focuses on the effect that this increase would have on the...
