Nitrate and pesticide transport under pear production in clay and sandy soil

Creator:: Cao, Weidong
Abstract:: Groundwater contamination on irrigated land is of concern in this nation and around the world. In order to reduce the potential of groundwater contamination by agricultural practices such as irrigation, fertilizer and pesticide application, vadose-zone monitoring and sampling are needed. The main objective of this study was to evaluate impacts...

Remediation of heavy-metal contaminated soils using succinic acid

Creator:: Kaul, Arvind
Abstract:: Succinic acid, a low molecular weight dicarboxylic acid was used to leach out heavy metals from Willamette Valley soil (contaminated separately with lead, copper, and zinc) in form of water-soluble organo-metal complexes. The research tasks included developing synthetic contaminated soils representative of those found at Superfund sites and making heavy...

Nitrate and water under terraced dryland wheat production in Oregon

Creator:: Strock, Jeffrey S.
Abstract:: Dry land agriculture using summer fallow is a common crop production practice in the Columbia Plateau region of eastern Oregon. Farmed-over level terraces are used to control surface water runoff and soil erosion. More than 70 percent of the average annual precipitation around Pendleton, Oregon (350 - 400 mm) falls...

How soil properties affect groundwater vulnerability to pesticide contamination

Creator:: Huddleston, J. H. (James Herbert), 1942- and Oregon State University. Extension Service
Abstract:: Four factors govern the potential for groundwater contamination by pesticides passing through the soil: • Properties of the soil • Properties of the pesticide • Hydraulic loading on the soil • Crop management practices

Soil column desorption studies on a chromium contaminated soil

Creator:: Ball, Bruce L.
Abstract:: Soil column studies were performed on a chromium contaminated soil from the United Chrome Products Superfund Site currently undergoing a pump-and-treat cleanup process. The goal of the research was to provide insight into the feasibility of chemically changing the injection fluid of the pump-and-treat system to enhance hexavalent chromium (Cr(VI))...

An overview of the Oregon Water Quality Decision Aid (OWQDA) : a tool for assessing groundwater contamination risk from specific soil-pesticide combinations

Creator:: Huddleston, J. H. (James Herbert), 1942- and Oregon State University. Extension Service
Abstract:: The Oregon Water Quality Decision Aid (OWQDA) is a first-tier screening tool that allows you to make a broad determination of the likelihood that a specific chemical, when applied to a specific Oregon soil, will move through the soil and contaminate groundwater. This determination is called the groundwater vulnerability rating.
