Cover Story: We investigated groundwater nitrate contamination in the Central Valley aquifer, California, USA, in relation to the source variables, aquifer characteristics, and geochemical conditions using three different statistical methods: Geodetector (GED), Principal Component Analysis (PCA) and Geographically Weighted Regression (GWR). Our comparative analysis of the three methods showed that GED was more advantageous, because it was less restrictive on input data, its output was more intuitive to interpret, and it captured all aspects of what the other two methods did. GED detected precipitation, fertilizer, manure, elevation, and clay as significant variables in controlling the spatial distribution of groundwater contamination in the Central Valley aquifer. San Joaquin Basin and Tulare Basin were identified as vulnerable regions with a higher percent of wells containing above 5 mg/L of nitrate. View the paper
