Abstract
A data summary was prepared to assess the quality of ground water and surface water in the Warwick aquifer area. During 1967-93, a total of 205 samples were collected from 61 wells and 18 surface-water locations, and the samples were analyzed for various water-quality constituents. Overall, the quality of ground water in the Warwick aquifer is within the selected drinking water guidelines for North Dakota, and the quality of water from wells less than or equal to 25 feet deep and wells greater than 25 feet deep is similar. Only a few water-quality constituents had concentrations that exceeded the selected drinking water guidelines for North Dakota. Arsenic concentrations neared or exceeded North Dakota drinking water standards in samples collected from two wells greater than 133 feet deep located within the production well field area. Thus, arsenic may be a concern in deeper portions of the aquifer. The quality of the surface water in the Warwick aquifer area was similar to the quality of the ground water in the aquifer. However, specific conductance, pH values, and concentrations of common agricultural pesticides generally are greater in the surface water than in the ground water.
