Available in PDF, EPUB and Kindle. Book excerpt: This new book focuses on sampling and analysis, radon and radium in water supply wells, predictive models, geologic and hydrogeologic controls that influence radon occurrence, monitoring radon and other radioactivity from geologic sources and mining impacts on occurrence of radioactivity in ground water. Also discussed are occurrence, testing, treatment, and reduction of radon from groundwater. Because the most severe health hazard from indoor radioactivity results from inhalation of short-lived radioactive decay products of radon, the EPA scheduled a major conference early in 1987 on Radon, Radium, and Other Radioactivity in Ground Water-Hydrogeologic Impact and Application to Indoor Airborne Contamination. The result is this book.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Midwestern Cambrian-Ordovician aquifer system (MCOAS) is a valuable source of drinking water in the North Central United States, but can contain elevated levels of naturally occurring radium (Ra). Long-term consumption of Ra in drinking water is linked to an increased risk of bone cancer, and is therefore federally regulated in the U.S. at 185 millibecquerels per liter (mBq/L) or 5 picocuries per liter (pCi/L) for the total of 226Ra and 228Ra. While the hydrogeochemical conditions associated with elevated activity Ra in the MCOAS are well documented, less is known about how Ra occurrence is affected due to hydrogeochemical changes initiated by natural and anthropogenic aspects. This dissertation uses field and modeling studies to explore Ra occurrence when hydrogeochemical change is instigated by factors including natural hydrogeologic conditions, release of organic contaminants to the subsurface, and well field management. Radium activity increases as groundwater evolves along a regional flow path and approaches the boundary of the Maquoketa shale, a regional confining unit; here, the aquifer becomes locally confined and groundwater is older with geochemical conditions conducive to Ra mobility, including low dissolved oxygen and elevated total dissolved solids (TDS). A complex organic chemical mixture released to the subsurface alters aquifer pH, redox, and TDS conditions, resulting in elevated Ra activity within the dissolved phase plume that highlights the importance of characterizing Ra at hydrocarbon-contaminated sites. As demonstrated by groundwater flow modeling, well construction and pumping rates can alter hydraulic gradients that enhance groundwater exchange between units of different geochemistry and modify the contribution of groundwater from stratigraphic units with different Ra activity to wells. Overall, this dissertation provides insight into how environmental and anthropogenic factors influence hydrogeochemical conditions and Ra occurrence in groundwater, and can help guide long-term groundwater management strategies for mitigating Ra activity in groundwater pumped from the MCOAS.
