Atrazine In A Stream-Aquifer System: Transport Of Atrazine And Its Environmental Impact Near Ashland, Nebraska, Darryl A. Blum, James D. Carr, Ralph K. Davis, Darryll T. Pederson Jan 1993

Atrazine In A Stream-Aquifer System: Transport Of Atrazine And Its Environmental Impact Near Ashland, Nebraska, Darryl A. Blum, James D. Carr, Ralph K. Davis, Darryll T. Pederson

Nebraska Water Center: Faculty Publications

The municipal wellfield for Lincoln, Nebraska, consists of 44 wells located adjacent to the Platte River near Ashland, Nebraska. The herbicide atrazine was monitored in the river and two transects of monitoring wells. The amount of atrazine transported down the Platte River in 1989, 1990, and 1991 was shown to increase each year. Induced recharge from the Platte River results in movement of atrazine from the river into the aquifer. A 21-day lag time was determined for the movement of atrazine from the river to a transect of monitoring wells 10 feet west of the bank. The role that colloids …


G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin Jan 1993

G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is a glossary of water quantity, quality and human health related terms involving water. Terms are defined in contexts that could affect Nebraskans. We depend upon water for our very existence. The impact of water quality and quantity issues has never been greater. Yet the terminology used to describe the water we drink, the water we provide to plants and animals, the water stored underground, in lakes, rivers, and oceans, is not well understood by many Nebraskans. This listing of water-related terms is intended to reduce the potential for misunderstanding presentations made by elected officials, environmental agencies and …


G93-1128 Understanding Groundwater, William L. Kranz, Delynn Hay, James W. Goeke Jan 1993

G93-1128 Understanding Groundwater, William L. Kranz, Delynn Hay, James W. Goeke

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides information on how groundwater exists, where it exists, and how it moves. Key definitions are highlighted. Water is the life blood of every living creature on earth. Approximately 70 percent of the earth's surface is covered with water. Through the wonders of nature, water can take on many different forms, from the water we drink, to the ice we use to chill a glass of lemonade, to the water vapor used to steam clean equipment. It is easy to understand the significance water plays in our lives, but it may be much more difficult to understand the …


The Potential Effects Of Climate Change On Summer Season Dairy Cattle Milk Production And Reproduction, Peggy L. Klinedinst, Donald A. Wilhite, G. Leroy Hahn, Kenneth G. Hubbard Jan 1993

The Potential Effects Of Climate Change On Summer Season Dairy Cattle Milk Production And Reproduction, Peggy L. Klinedinst, Donald A. Wilhite, G. Leroy Hahn, Kenneth G. Hubbard

National Drought Mitigation Center: Faculty Publications

The potential direct effects of possible global warming on summer season dairy production and re-production were evaluated for the United States and Europe. Algorithms used for milk production and conception rate were previously developed and validated. Three widely known global circulation models (GISS, GFDL, and UKMO) were used to represent possible scenarios of future climate. Milk production and conception rate declines were highest under the UKMO model scenario and lowest under the GISS model scenario. Predicted declines for the GCM scenarios are generally higher than either “l year in 10” probability-based declines or declines based on the abnormally hot summer …

Estimation Of Relative Pesticide Leaching In Nebraska Soils, P. J. Shea, L. N. Mielke, W. D. Nettleton

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A computational procedure (RIPS, Relative Index for Pesticides and Soils) was developed as a conservative estimator of pesticide leaching and groundwater contamination based on soil and pesticide properties, and water table depth. RIPS values offer guidance in pesticide selection and identify situations where a detailed site-specific evaluation should be conducted.
