Barry C. Poulton, Teresa J. Rasmussen, Casey J. Lee
2007, Fact Sheet 2007-3044
Johnson County is one of the fastest growing and most populated counties in Kansas. Urban development affects streams by altering stream hydrology, geomorphology, water chemistry, and habitat, which then can lead to adverse effects on fish and macroinvertebrate communities. In addition, increasing sources of contaminants in urbanizing streams results in...

A framework for assessing the sustainability of monitored natural attenuation
Francis H. Chapelle, John Novak, John Parker, Bruce G. Campbell, Mark A. Widdowson
2007, Circular 1303
The sustainability of monitored natural attenuation (MNA) over time depends upon (1) the presence of chemical/biochemical processes that transform wastes to innocuous byproducts, and (2) the availability of energy to drive these processes to completion. The presence or absence of contaminant-transforming chemical/biochemical processes can be determined by observing contaminant mass...
