This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater from the High Plains aquifer is vital for food production and a growing human population in the Great Plains region of the United States. Understanding how groundwater quality is changing in response to anthropogenic and natural processes is critical to effectively managing this resource. Our study considers variation in groundwater geochemistry in the Great Bend Prairie aquifer, a portion of the High Plains aquifer in southcentral Kansas. We collected samples during summer 2016 from 24 monitoring wells and compared our results to data collected previously from the same wells from 1979 to 1987. We sampled 13 wells screened in the upper portion of the aquifer (avg. depth 72 ft), 10 wells screened near the aquifer base (avg. depth 141 ft), and one well screened in underlying bedrock. Compared to initial samples, samples we collected tended to have higher total dissolved solids (TDS) and nitrate content, particularly those we collected from the upper aquifer. Compared to initial samples, TDS was 78 mg/L higher in samples we collected from the upper aquifer and 373 mg/L lower in samples we collected from the aquifer base on average. Nitrate exceeded the U.S. standard for public supplies of drinking water (10 mg/L as N) in seven of the samples we collected, compared to only two samples collected previously. Compared to previous samples, nitrate concentrations were 9.5 and 3.9 mg/L as N higher on average in samples collected from the upper aquifer and aquifer base, respectively. Based on a mixing analysis, variation in the salinity of our samples primarily reflects the dilution of natural Permian brines by freshwater recharge throughout the area. However, salinity decreases observed in four samples reflects flushing of initial oil brine contamination over time, salinity increases in two samples may be due to evapotranspiration, and salinity increases in two samples may reflect migration of oil-brine contamination towards the site. Stable nitrogen (15N/14N) and oxygen (18O/16O) isotope ratios in our samples primarily fall within the range typical of nitrification of ammonium-based fertilizers with potential contributions from manure or sewage. In our analysis of the microbial community, we observed groups capable of denitrification, including genera within Nitrospirae, Firmicutes, and Proteobacteria. Despite their presence, our results demonstrate that water quality in the aquifer has degraded over the past 30 to 40 years due to nitrate accumulation.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The High Plains aquifer supplies nearly one-third of the irrigation water used in the U.S. and drinking water for millions of people, making it a critical groundwater resource. Recent research indicates that nitrate accumulation is degrading groundwater quality in the Great Bend Prairie Aquifer, a portion of the High Plains Aquifer in south-central Kansas. However, little is known about the extent of the problem for domestic (i.e., private) wells, which are used by >30,000 people in the area. To fill this knowledge gap, we collected and geochemically analyzed groundwater samples from 63 domestic wells in the aquifer and combined our results with data collected in 2016 from 23 monitoring wells. We characterized water quality relative to standards for drinking water and used our results in mixing and geospatial calculations to better understand sources of salinity and relationships to land use, respectively. In the private well samples, nitrate as N concentrations averaged 11.2 mg/L as N and exceeded the U.S. Environmental Protection Agency maximum contaminant level for public water supplies (10 mg/L as N) in 28 of 63 samples. Chloride, and sulfate concentrations exceeded the standards in five private water samples. We found that nitrate and uranium concentrations significantly correlate, consistent with studies that have found that nitrate contamination can trigger uranium release from sediments. Using 10 different land use/land cover classes and buffer zones of different radii around each well, we evaluated correlations between nitrate contamination and land use. Primarily, we found negative relationships between the occurrence of nitrate and the urban land use/land cover class. We used a mixing analysis to evaluate the impact on salinity from nearby oil and gas development, evapotranspiration, and natural brine contribution from geological formations underlying the aquifer. Agreeing with previous findings, our results demonstrate that the main contributor of salinity in the aquifer is Permian saltwater, although some data points show influence from evapotranspiration and contamination from oil and gas brine. We expect that these results will better define the scale of the nitrate contamination and general water quality concerns and their links to land use in the study region.
