| Title | Estimating the probability of elevated nitrate (NO2+NO3-N) concentrations in ground water in the Columbia Basin Ground Water Management Area, Washington |
| Creator | Frans, Lonna M. |
| Subject | Water quality; Groundwater; Nitrates; |
| Coverage | Columbia River; Washington; |
| Description | Logistic regression was used to relate anthropogenic and natural factors to the occurrence of elevated nitrate concentrations in the Columbia Basin GWMA and develop models that predict the probability that nitrate concentrations in ground water exceed either 3 mg/L or 10 mg/L. Explanatory variables that were considered for inclusion in the models included surficial geology, soils, ground-water recharge rates, land use, presence of canals near the well, presence of irrigation near the well,... |
