Summary
This dataset reports total arsenic (AsTot) results analyzed using an in-field biosensor system, Field-Ready Electrochemical Detector for Arsenic (FRED-Arsenic), developed by FREDsense Technologies Corp., Calgary, Alberta, Canada. Samples were collected from two public-supply wells (NH-SGW 93 and NH-SGW 65) and one private well (NH-KFW 87). NH-SGW 93 and NH-KFW 87 both withdraw water from a crystalline-rock aquifer. NH-SGW 65 withdraws water from a glacial sand and gravel aquifer. Twelve samples for NH-KFW 87 were collected and analyzed on May 14, 2019 with sample times ranging from 0730 to 1800, and 12 samples were collected and analyzed on August 20, 2019 with sample times ranging from 0830 to 1320. Eleven samples for NH-SGW 93 were [...]

Eleven samples for NH-SGW 93 were collected and analyzed on May 15, 2019 with sample times ranging from 0838 to 1437, with the last sample collected when the pump was turned off; 12 sampled were collected and analyzed on August 21, 2019 with sample times ranging from 0807 to 1159. Twelve samples for NH-SGW 65 were collected and analyzed on May 16, 2019 with sample times ranging from 0931 to 1400; 12 samples were collected and analyzed on August 22, 2019 with sample times ranging from 0813 to 1057.

To assess variations in arsenic concentrations as a result of redox-related conditions in three drinking-water wells in New Hampshire, water-quality samples were collected hourly, under pumping conditions, at three sites on two separate days in May and August, 2019. These samples were analyzed in the field using a novel integrated biosensor system created by FREDsense Technologies (Calgary, Alberta, Canada), to assess the utility of using a field sensor to monitor and manage arsenic exposures in near real-time. The FRED-Arsenic system was used to analyze 72 individual samples for arsenic (AsTot). For comparison, samples also were collected and analyzed in a laboratory setting, those results can be found in Degnan and others, 2020, Lindsey and Johnson, 2018, and Levitt and others, 2019 (see cross reference section of this metadata for full citation information).
