Testing dataset for independent analysis of New Hampshire arsenic model

Existing multivariate logistic regression models that predict the probabilities of arsenic concentrations at 1, 5, and 10 micrograms per liter in bedrock aquifers of New Hampshire were tested using bedrock wells not included in the model development. This data release contains a table of measured arsenic concentrations and associated model input variables for the model testing dataset. Location data are censored to the county level.
