The effectiveness of water-treatment systems for arsenic used in 11 homes in Southwestern and Central Ohio, 2013

Abstract

Temperature in degrees Celsius (°C) may be converted to degrees Fahrenheit (°F) as °F = (1.8 × °C) + 32. Specific conductance is given in microsiemens per centimeter at 25 degrees Celsius (µS/cm at 25 °C).

Hydrogeology and water quality of sand and gravel aquifers in McHenry County, Illinois, 2009–14, and comparison to conditions in 1979

“…Drinking-water sources tapped by residential supply wells could be at risk where those wells are located near monitoring wells with elevated arsenic levels (fig, 27). Effective treatment methods for supply wells are available, including filtration, ion-exchange systems, and reverse-osmosis systems that can be used to reduce arsenic levels in drinking water (Thomas and Eckberg, 2015). Aluminum concentrations ranged from 1.7 to 38.9 µg/L, with the highest concentration detected at well 13-NUN-D ( fig.…”

“…Iron concentrations in excess of 300 µg/L can affect taste and cause staining of fabrics and household fixtures such as plumbing (National Ground Water Association, 2010). Like arsenic concentrations, iron concentrations also can be substantially reduced in drinking water through various water treatment methods (Thomas and Eckberg, 2015).…”

Water quality of sand and gravel aquifers in McHenry County, Illinois, 2020 and comparisons to conditions in 2010

“…In general, the groundwater in McHenry County is suitable for drinking water, and some of the aesthetic issues could be mitigated with home water-treatment systems such as water softeners. The concentrations of many of these constituents could also be reduced with an at-home water-treatment system such as a carbon filtration, ion-exchange systems, and reverse-osmosis systems (Thomas and Eckberg, 2015).…”

Science to support the understanding of Ohio's water resources, 2016-17

“…Three types of systems were investigated and the results varied widely, ranging from 2-to 90-percent removal. In general, the effectiveness of arsenic removal was related to the chemical characteristics of the raw water and to maintenance of the treatment equipment (Thomas and Ekberg, 2016).…”
