Title

SPATIAL ANALYSIS OF THREE AGRICHEMICALS IN GROUNDWATER OF ISFAHAN USING GS+

Pages

  71-80

Abstract

 The purpose of this study was to undertake a spatial analysis of TOTAL ORGANIC CARBON, ELECTRICAL CONDUCTIVITY and NITRATE, in order to produce a pollution dispersion and prediction map for the investigated area in the province of Isfahan in Iran. The groundwater samples were collected from a zone as a pilot study area of 80 km2, including 25 water wells, based on the criteria of vulnerability assessment projects, that is, about one well per 3 km2, during four seasons in 2008-09. In order to make any inferences about the areas that did not have well data, a statistical relationship between explanatory TOTAL ORGANIC CARBON, ELECTRICAL CONDUCTIVITY and NITRATE variables related to well coordination was developed. The probability of the presence of elevated levels of the three compounds in the groundwater was predicted using the best-fit VARIOGRAM model. According to spatial analysis, the highest R2=0.789 achieved was related to ELECTRICAL CONDUCTIVITY and followed the exponential model with 0.266 for NO3- (spherical model) and 0.322 for TOTAL ORGANIC CARBON (exponential model) in the spring 2009. This showed the high confidence level for ELECTRICAL CONDUCTIVITY dataset and forecasted trends. The results of the spatial analysis demonstrated that the transfer trends of ELECTRICAL CONDUCTIVITY in the groundwater resources followed the route of groundwater movement in all seasons. However, for NITRATE and TOTAL ORGANIC CARBON, a definite trend was not obtained and pollution dispersion depended on many parameters.
