Pesticides -- Environmental aspects; Groundwater -- Pollution; Soils -- Pesticide content; EM (Oregon State University. Extension Service)Author: E. Kerle, P. Vogue, J. Jenkins, J. Huddleston. The vulnerability of a ground-water resource to contamination depends on intrinsic suscep- tibility as well as the locations and types of sources of naturally occurring and anthropogenic contamination, relative locations of wells, and the fate and transport of the contaminant(s).File Size: 2MB.
The Attenuation Factor (AF), a screening model, was used to evaluate the relative degree of vulnerability of groundwater to pesticide contamination in Louisa County, Virginia. The purpose of assessing the vulnerability of groundwater to pesticide leaching might be to either identify active ingredients that pose a potential threat, for example in a regulatory setting (FOCUS, ) or to identify soils and regions where pesticide usage is more likely to have negative environmental effects onFile Size: KB.
in assessments of groundwater vulnerability to pollution chemical properties of pesticides play extremely important role. Introduction Land productivity was, and still is, improved by using pesticides. Progress towards effective and, especially safe agrochemicals was very slow until the pe-riod after the Second World : Ireneusz Kajewski.
A probabilistic approach for the groundwater vulnerability to contamination by pesticides: the VULPEST model. Ecol. Modelling, The quantitative evaluation of the groundwater vulnerability to contamination by pesti- cides is the most effective way to prevent the cases of non-point source contamination and to protect the groundwater Cited by: Groundwater vulnerability to nitrate and pesticide contamination was evaluated using the DRASTIC system and supporting data on DRASTIC factors obtained from the Economic Research Service, U.S.
Department of Agriculture. The DRASTIC system was developed by the EPA to assess an area's relative vulnerability to groundwater contamination from either. This paper presents a demonstration of an integrated risk assessment and site investigation for groundwater contamination through a case study, in which the geologic and hydrogeological feature of the site and the blueprint of the fossil power plant (FPP) were closely analyzed.
Predictions for groundwater contamination in case of accidents were performed by groundwater Cited by: Nonpoint sources are the dominant sources of pesticides found in streams and groundwater.
Nonpoint sources include runoff to streams from agricultural and urban land, seepage to ground water in areas where pesticides are used, and deposition of pesticides from the atmosphere. Potential point sources of pesticides include pesticide manufacturing plants, mixing-and-loading facilities, spills, waste water recharge facilities (wells or basins), waste disposal sites.
Moreover, researchers attempt to consider more impact factors during the risk assessment of groundwater pollution by pesticides. Early inM. Soutter and A. Musy respectively applied three leaching models (AF, LEACHM, and LEACHA), coupling 1D Monte-Carlo simulations and geostatistics to assess groundwater contamination risks by pesticides Site assessment for groundwater vulnerability to pesticide contamination book a part of the upper Cited by: Vulnerability assessment is an essential step in assessing groundwater contamination.
This approach provides a visual analysis for helping planners and decision makers to achieve the sustainable management of water resources.
Comparative studies are applying different methodologies to result in the basic evaluation of the groundwater : Rizka Maria. Abstract. Published January Please look for up-to-date information in the OSU Extension Catalog: Pesticides may have adverse environmental effects if they are transported to groundwater and surface waters.
The vulnerability of water resources to contamination of pesticides must therefore be evaluated. Different stakeholders, with different objectives and requirements, are interested in such vulnerability assessments. Various assessment methods have been Cited by: 2.
As the human population grows, groundwater pollution from human activity also increases. There are a number of possible sources that could lead to groundwater contamination. Such as crude oil leakage in oil production, organic waste discharge, spills and leaks from underground storage tank and so : Hongqi Wang, Shuyuan Liu, Shasha Du.
Pesticide Risk in Groundwater provides an overview of the main issues concerning pesticide pollution of groundwater worldwide. The book is divided into five sections. Section I reviews experimental data of groundwater monitoring to indicate the extent of the problem on a global basis.
Based on this evaluation, herbicides are examined in depth. Groundwater vulnerability is a central concept in pollution risk assessment, yet its estimation has been largely a matter of expert judgment.
This work applies a method for the direct calculation of vulnerability from monitoring well observations of pesticide by: The results of the vulnerability assessment followed directly from the method's assumptions and underlying principles.
In general, the thicker the overlay of clayey glacial drift or shale, the less susceptible are wells or aquifers to contamination. Where overlying materials are thin or sandy.

Summary - Development of a Simple and Practical Tool for the Evaluation of Groundwater Vulnerability to Contamination by Pesticides.
General guidance on data requirements to assess the fate and behaviour as well as environmental exposure of pesticides in Groundwater can be found on the FOCUS website. A number of environmental exposure modelling tools and guidance documents for use in the EU have been produced by the FOCUS initiative, (FOrum for the Co-ordination of Pesticide Fate.
The authors provide a comprehensive review of existing literature on the assessment of groundwater vulnerability and then describe an improved methodology, which is developed based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward.

As illustrated in Box the concept of ground water vulnerability to contamination has different meanings for different people. In its broadest context, ground water vulnerability refers to whether or not an underlying aquifer will become contaminated as a result of activities at the land surface.
higher the DRASTIC index, the greater the vulnerability of the aquifer to contamination. A site with a low DRASTIC index is not free from groundwater contamination, but it is less susceptible to contamination compared with the sites with high DRASTIC indices.
The method used in this study is called DRASTIC. Another DRASTIC method, called PesticideFile Size: 2MB.
Arid and semiarid areas face major challenges in the management of scarce groundwater. This valuable resource is under pressures of population, economic expansion, contamination and over-exploitation. This research investigates groundwater vulnerability to pesticide contamination in the Al-Kharj area of Saudi Arabia.
It explores the spatial distribution of pesticide Cited by: for contamination, mostly in areas where the slope of the land surface is more than 12 percent. Nearly all ﬁelds on the Navajo Indian Irrigation Project were assessed to have the most potential for contamination.

Groundwater contamination is a serious threat to water supply. Risk assessment of groundwater contamination is an effective way to protect the safety of groundwater resource.
Groundwater is a complex and fuzzy system with many uncertainties, which is impacted by different geological and hydrological by: 9. Prolonged exposure to pesticides can cause adverse effects to human health and the ecosystem. Spatial distribution maps of groundwater contamination were developed using GIS.
These maps will help risk managers identify vulnerable sources and provide a relative assessment of pesticide hazards to human health and the by: Author(s) V. Guinot, M. Vauclin, A. Aboujaoude & C. Freissinet Abstract. An operational definition of groundwater resource vulnerability to contamination by pesticides as well as a methodology to assess it, are presented in this : V.
Guinot, M. Vauclin, A. Aboujaoude, C. Freissinet. In the last decade, several authors have used this model to study the effect of different pesticides to groundwater vulnerability [,]. In other cases, a Bayesian methodology has been used to calculate the vulnerability of groundwater to pesticide contamination directly from monitoring by: 6.
Groundwater and Pesticides About 50 percent of the U.S. population relies on groundwater for drinking water. Rural populations utilizing groundwater for drinking water may reach 95 percent. Groundwater feeds drinking-water wells.
Because of the potential risk to human health, pesticide contamination of groundwater is a national topic.

Since this study employs a statistical approach to vulnerability assessment, the literature review emphasizes those studies that have applied statistical met hods to this problem.
In addition, the use of nitrate as an indicator of vulnerability to contamination by agricultural chemicals is discussed. Groundwater Vulnerability is a term used to represent the natural ground characteristics that determine the ease with which groundwater may be contaminated by human activities.
More scientifically, groundwater vulnerability embodies the characteristics of the intrinsic geological and hydrogeological features at a site that determine the ease of.
The purpose of vulnerability investigation is to protect groundwater quality through spotting the light on those vulnerable areas by decision makers. Groundwater vulnerability can be assessed throughout three different ways: (1) site-specific evaluation by hydrogeologists, (2) pesticide destiny, and (3) index methods .
The assessment of the vulnerability of soil and groundwater resources to pesticide contamination is important to reduce the risk of environmental pollution. The applicability of the expanded attenuation factor (EAF) to assess leaching potential of 30 pesticides was investigated under four recharge rates (– m d−1) in the arid environment of the Jazan watershed.

et al.,Groundwater vulnerability to pesticide contamination in the Assiniboine. Introduction. Groundwater is the most important water resource on earth (Villeneuve et al. ).Groundwater quality is under considerable threat of contamination especially in agriculture-dominated areas due to intense use of fertilizers and pesticides (Giambelluca et al.
; Soutter and Musy ; Lake et al. ; Thapinta and Hudak ; Chae et al. ).Cited by: Invarious UN organizations launched a collaborative effort to assess the vulnerability of groundwater in several African cities.
The project addressed the issue of aquifer vulnerability and the protection of groundwater quality. This book is a. Vulnerability is categorized into specific and intrinsic vulnerability. Specific vulnerability is the vulnerability of groundwater to a contaminant and is a function of pollutant properties, anthropogenic activities, and physical parameters (Babiker et al.
).Intrinsic vulnerability refers to the ease with which a contaminant is added to the ground surface and Cited by: 5.
