Numerous approaches have been used or proposed for assessing ground water vulnerability. They range from sophisticated models of the physical, chemical, and biological processes occurring in the vadose zone and ground water regime, to models that weight critical factors affecting vulnerability through either statistical methods or expert judgment.

The Pesticide Root Zone Model Groundwater Aquifer vulnerability analysis using the pesticide root-zone model book was developed as a regulatory model to estimate pesticide concentrations in vulnerable groundwater sources as part of a North American Free Trade Agreement (NAFTA) to develop a harmonized groundwater modeling protocol.

Faisal Anwar* and Lawrence Anak Saing Department of Civil Engineering, Curtin University of Technology, GPO Box U, Perth WA(AUSTRALIA) Received Febru Accepted Aug ABSTRACT. Adsorption, degradation, and movement are the key processes conditioning the behavior and fate of pesticides in the soil.

Six processes that can move pesticides are leaching, diffusion, volatilization, erosion and run-off, assimilation by microorganisms, and plant uptake.

Leaching is the vertical downward displacement of pesticides through the soil profile and the unsaturated zone, and finally Cited by: 6. Aquifer vulnerability analysis using the pesticide root-zone model book, the vulnerability of groundwater to pesticide leaching may be evaluated by indices and overlay-based methods, by statistical analyses of monitoring data, or by using process-based models of pesticide fate.

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 developed in the by: 2.

A groundwater risk assessment was carried out for 30 potable water supply systems under a framework of protecting drinking water quality across South Australia. A semi-quantitative Groundwater Risk Assessment Model (GRAM) was developed based on a “multi-barrier” approach using likelihood of release, contaminant pathway and consequence by: As part of a process to improve confidence in the results of regulatory modeling, predictions of pesticide root zone model (PRZM) were compared with measured data collected in nine different runoff field studies.

This comparison shows that PRZM provides a reasonable estimate of Cited by: survey report for your area, the OSU Extension Pesticide Properties Database (EM ), and the OSU Extension Soil Sensitivity Database.

A quantitative approach to aquifer vulnerability mapping. derived from a series of analytical and semi-analytical solutions to the advection–dispersion equation that include root zone and unsaturated water movement effects on the transport process. model results will be approximate and more sensitive modelling procedures will be Cited by: eb - Protecting Groundwater from Pesticide Contamination The pesticide's fate depends on the cumulative effects of pesticide and soil properties, application methods, and site conditions.

Several factors that affect pesticide movement are discussed below. The importance of these factors to leaching varies with each situation. Pesticides are widely used all over the world to protect crops in agricultural fields. Uncontrolled and improper pesticide applications have led to their presence in the environment exceeding permissible limits [1,2,3,4].It has been observed that groundwater is most affected by pesticide applications in agricultural fields [5,6,7,8,9].The pesticide contamination of groundwater is generally.

The model can objectively assess the groundwater vulnerability of different areas, and its assumption that all regions of the aquifer has a uniform trend. But all the geological, hydrogeological and other conditions are different, and the model calculations defect, the DRASTIC method has some : Hongqi Wang, Shuyuan Liu, Shasha Du.

About PRZM_SW General InformationPRZM (Pesticide Root Zone Model) is a one-dimensional non-deterministic compartmental model for the prediction of chemical movement in unsaturated soils by vertical chromatographic leaching.

As a consequence, there is a strong social demand for designing safe cropping systems with less or no hazardous pesticides.

The vadose zone (often called the unsaturated zone) is commonly defined as the geologic media spanning from the land surface to the groundwater table of the first unconfined aquifer (Stephens ).The vadose zone is known to play a critical role within the biosphere: (1) as a storage medium to supply water to the plants and atmosphere, and (2) as a controlling agent in the transmission of Cited by: 1.

If the first tier model suggests that pesticide levels in water may be unacceptably high, a more refined model is used as a second tier assessment. The second tier model is actually a combination of two models: the Pesticide Root Zone Model (PRZM) and the Exposure Analysis Model System (EXAMS).
