An Assessment Of Water Quality In Ensign Hollow, Clayton And Fayette Counties, In Northeast Iowa, Rick Klann, Jaime Platts
An Assessment Of Water Quality In Ensign Hollow, Clayton And Fayette Counties, In Northeast Iowa, Rick Klann, Jaime Platts
Journal of the Iowa Academy of Science: JIAS
Water quality and benthic invertebrates in the Ensign Hollow watershed, southwestern Clayton County and southeastern Fayette County, Iowa, were monitored from 2000 to 2001. Measurements of physical and chemical parameters of water quality, as well as analysis of benthic invertebrates, all indicated that streams of the Ensign Hollow watershed were exposed to slight organic pollution. Furthermore, the greatest threat to this watershed appeared to be sedimentation introduced through runoff.
Hydrogeology Of The Devonian-Silurian Carbonate Aquifer, Northern Cedar Rapids, Iowa, Keith E. Schilling
Hydrogeology Of The Devonian-Silurian Carbonate Aquifer, Northern Cedar Rapids, Iowa, Keith E. Schilling
Journal of the Iowa Academy of Science: JIAS
The hydrogeology of the Devonian-Silurian carbonate aquifer was investigated at a hazardous waste site in northern Cedar Rapids, Iowa. Data collected at the project site included bedrock cores, specific capacity measurements in discrete packer intervals and monitoring wells, hydraulic-head measurements and groundwater samples collected from select Devonian and Silurian wells.
Ecoregions And Subregions Of Iowa: A Framework For Water Quality Assessment And Management, Glenn E. Griffith, James M. Omernik, Thomas F. Wilton, Suzanne M. Pierson
Ecoregions And Subregions Of Iowa: A Framework For Water Quality Assessment And Management, Glenn E. Griffith, James M. Omernik, Thomas F. Wilton, Suzanne M. Pierson
Journal of the Iowa Academy of Science: JIAS
Ecoregion frameworks are valuable tools for inventorying and assessing environmental resources, for setting resource management goals, and for developing biological criteria and water quality standards. In a collaborative project between the Iowa Department of Natural Resources (DNR) and the U.S. Environmental Protection Agency (EPA), we have refined boundaries of the EPA's five ecological regions of Iowa and defined six subregions of the Western Corn Belt Plains ecoregion within the state. Lists of candidate stream reference sites have been developed to date for the seven largest regions, and the sites were visited and evaluated by Iowa DNR and U.S. EPA personnel …
