Summary

To help characterize the groundwater system at Homestake Mining Company Superfund Site near Milan, New Mexico, the U.S. Geological Survey collected borehole geophysical and groundwater-quality data in cooperation with the U.S. Environmental Protection Agency during July–October 2016. The following borehole geophysical data were collected from wells at or near the Homestake Mining Company Superfund Site: induction, fluid resistivity, natural gamma, spectral gamma, fluid temperature, caliper, casing collar locator, optical televiewer, and electromagnetic flow meter logging (ambient and stressed). The geophysical data were used to evaluate well construction, stratigraphy, distribution of potassium, uranium, and thorium, locations of [...]

Purpose

The purpose of this data release is to document geophysical and water-quality data collected during July–October 2016 at or near the Homestake Mining Company Superfund Site near Milan, New Mexico. Data were collected to help identify differences in chemical signatures from groundwater of the alluvial and Chinle aquifers in the San Mateo Basin at or near the Homestake Mining Company, Superfund Site near Milan, New Mexico. Each type of data helps contribute to identifying the source of groundwater to a particular well. For instance, major ions can be used in a piper diagram to visualize the major chemistry signatures of waters while uranium isotope ratios identify natural versus anthropogenic input of uranium (U). Age-dating tracers, such as chlorofluorocarbons (CFCs) or Tritium (H3), help to identify when aquifers were recharged and can aid in calculating groundwater flow rates and residence times of groundwater. A primary objective of collecting these data is to help differentiate chemical signatures from the three main types of water in the alluvium and Chinle aquifers at or near the superfund site. The three main types of the groundwater are: (1) waters unaffected by local or regional tailing operations, (2) waters affected by local tailing operations, and (3) waters affected by regional, upgradient tailing operations in the San Mateo Basin. The second objective of collecting these data is to identify anthropogenic and background water chemistry of U at selected specific well locations at or near the Homestake Mill Site for the alluvium and Chinle aquifers.
