Spatial Inference of Nitrate Concentrations in Groundwater
We develop a method for multi-scale estimation of pollutant concentrations, based on a nonparametric spatial statistical model. We apply this method to estimate nitrate concentrations in groundwater over the mid-Atlantic states, using measurements gathered during a period of ten years. A map of the fine-scale estimated nitrate concentration is obtained, as well as maps of the estimated county-l...
متن کاملGeostatistical Methods for Mapping Groundwater Nitrate Concentrations
The purpose of this study is to evaluate the spatial changes of groundwater nitrate concentrations by using geostatistical methods based on data from 119 groundwater wells. Geostatistical methods have been used widely as a convenient tool to make decision on the management of behavior of hydrochemical parameters in groundwater. To evaluate the spatial changes nitrate concentrations in groundwat...

متن کاملVulnerability of Recently Recharged Groundwater in Principle Aquifers of the United States To Nitrate Contamination
Recently recharged water (defined here as <60 years old) is generally the most vulnerable part of a groundwater resource to nonpoint-source nitrate contamination. Understanding at the appropriate scale the interactions of natural and anthropogenic controlling factors that influence nitrate occurrence in recently recharged groundwater is critical to support best management and policy decisions t...
