Assessing the Lead Solubility Potential of Untreated Groundwater of the United States.
TL;DR: A geochemical reaction model was developed that included pure Pb minerals and solid solutions of calcite and apatite to estimate the lead solubility potential (LSP) for over 8300 untreated groundwater samples collected from domestic and public-supply sites between 2000 and 2016 in the U.S.

TL;DR: Results of this preliminary study indicate that effective national or regional assessments of BGW resources should include geochemical characterizations that are guided in part by specific use and treatment requirements.
Journal ArticleDOI
Gross-beta activity in ground water: natural sources and artifacts of sampling and laboratory analysis
TL;DR: In this article, the authors analyzed about 800 ground-water samples from 5 groundwater regions of the United States to evaluate the utility of the gross-beta activity measurement and found that the contribution from long-lived radionuclides in ground water, and ingrowth of beta-emitting radions during holding times between collection of samples and laboratory measurements, can contribute to the observed gross-β activity.
Journal ArticleDOI
AMDTreat 5.0+ with PHREEQC titration module to compute caustic chemical quantity, effluent quality, and sludge volume
TL;DR: In this paper, a geochemical program PHREEQC has been incorporated with AMDTreat 5.0+ to estimate the quantity and cost of caustic chemicals to attain a target pH, the chemical composition of the treated effluent, and the volume of sludge produced by the treatment.
