“…† These four metals were present in both the coking wastewater and in the water following biological treatment, such that adsorption results are applicable to treating both pre-and post-biologically treated samples. Metals detected here were also found in varying concentrations across coal wastewater and contaminated water streams, including: CW samples from Shanxi Province, 65 water contaminated from coal slurry in the United States, 66 water sampled from coal mines in India, 67 and in water eluted through in situ gasied coal mines in Poland. 68 As such, while there is considerably heterogeneity in all waste systems, the four metals used in this study represent a cross-section of industrial coal waste systems.…”

“…Averages of Cr in WDS, PP and HWT were 0.60-0.63, 0.56-0.57 and 0.68-0.79 μg/L respectively. Higher Cr in HWT can be partially attributed to increased reaction with the wall and deposits in the HWT (Wigginton et al 2007). The averages of As, Fe and Zn were higher in HWT than WDS (p-value ¼ 0.002).…”

Supply water is an important source of human exposure to heavy metals through the oral pathway. Due to stagnation of water in plumbing systems, exposure concentrations of heavy metals from tap water can be higher than water distribution systems (WDS), which is often ignored by the regulatory agencies. In this study, concentrations of a few heavy metals (arsenic (As), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), magnesium (Mg), zinc (Zn) and iron (Fe)) and water quality parameters were monitored in WDS, plumbing pipe (PP) and hot water tanks (HWT). Multiple models were trained for predicting metal concentrations in PP and HWT, which were validated. Heavy metal concentrations in HWT were 1.2–8.1 and 1.4–6.7 times the concentrations in WDS and PP respectively. Concentrations of As, Cr, Cu, Hg and Zn were in the increasing order of WDS, PP and HWT. Concentrations of Cr and Fe were higher during summer while Cu and Zn were higher in winter. The models showed variable performances for PP and HWT (R2: PP = 0.61–0.99; HWT = 0.71–0.99). The validation data demonstrated variable correlation coefficients (r: PP = 0.45–0.99; HWT = 0.83–0.99). Few models can be used for predicting heavy metals in tap water to reduce the cost of expensive sampling and analysis.

“…For example, crises such as the Martin County coal sludge disaster resulted in approximately 300 million gallons of toxic waste and heavy metals released into the waterways (Scott etal. 2005, 2012, 2016; McSpirit, Hardesty, and Welch 2002; Shiber 2005; Wigginton, McSpirit, and Sims 2007). Therefore, in this article, we explore patterns of water insecurity in Appalachian Kentucky.…”

Water insecurity is a condition when affordability, reliability, adequacy, or safety of water is significantly reduced or unattainable resulting in jeopardized well‐being. Water insecurity co‐occurs with poverty and social and economic exclusion. It is gaining increasing attention from the scholarly community, but most work has focused on low‐ and middle‐income countries. In this article, we explore water insecurity in Appalachian Kentucky. Throughout the Appalachia region, water access and quality are compromised as a result of contamination from extractive industries (such as coal mining) and failure of infrastructure investment. The water problems have been reported by journalists, activists, and social and natural scientists who describe a reliance on discolored, sulfuric, and sometimes toxic water to meet household needs. In this article, we build upon applied anthropology studies of human–environment interaction to answer the exploratory question: “Do patterns about water acquisition and consumption exist in Appalachian Kentucky?” Our methodologies included participant observation and informal go‐along interviews at three sites based on convenience. The results are presented with rich ethnographic description, and reveal that preferences are influenced by the costs of water, the availability of water from different sources (wells, taps, mines, rain capture, etc.), and historic use patterns. We call for a culturally and historically informed approach to understand and measure water insecurity and water improvement efforts in Appalachia. Our ability to characterize water insecurity in low‐resource settings in the United States will allow for better understanding and visibility of the water‐related experiences of marginalized communities and serve as powerful policy inputs.
