     "text": "Arsenic is a naturally occurring element commonly associated with volcanic rocks and the soils/sediments derived from them (Welch and others, 1988; USEPA 2000). Human related activities, such as mining, irrigation, and the use of phosphate containing fertilizers, can influence the concentration of arsenic in groundwater (Welch and others, 1988; Campos, 2002; Busbee and others 2009; Lin and others, 2016). As groundwater moves through an aquifer with volcanic rocks and associated soils/sediments, it can mobilize arsenic contained in them (Cherry and others, 1979; USEPA, 2000). Consumption of water with arsenic concentrations exceeding the maximum contaminant level (MCL) has been associated with incidences of cardiovascular, liver, and neurological disease and certain cancers, including but not limited to, blood, lung, skin, kidney, and prostate (Agency for Toxic Substances and Disease Registry, 2014). In 2001, the U.S. Environmental Protection Agency (USEPA) lowered the MCL for arsenic in drinking water from 50 to 10 \u00b5g/L (USEPA, 2001). Using a statistical modeling approach to evaluate the regional occurrence of arsenic in basin-fill aquifers throughout the southwestern United States, Anning and others (2012) showed that much of Nevada\u2019s groundwater resources likely contain arsenic. A study published in 2022 on the occurrence of arsenic in groundwater used for domestic supply in Nevada showed that 22 percent of samples collected from 174 domestic wells exceeded the 10 \u00b5g/L drinking water criterion (Arienzo and others, 2022). While the form arsenic takes (speciation) isn\u2019t commonly evaluated as part of arsenic occurrence surveys, arsenic speciation is important to consider when treating drinking water for arsenic (Kanel and others, 2023). Generally, arsenate is more effectively removed from water than is arsenite (USEPA, 2001; Walker and others, 2008; Paul and others, 2010)."

A total of 190 groundwater samples were collected from wells and springs throughout Nevada. Concentrations of arsenic ranged from <1.6 to 2,408 micrograms per liter (\u00b5g/L); in most cases, arsenate was the dominant species. All arsenic data collected as part of this collaborative effort are available through the Water Quality Portal."
