This resource contains two datasets. Both the dataset contains groundwater arsenic measurements (with geo coordinates) from Araihazar, Bangladesh. All arsenic concentration is in ppb (ug/L).
Dataset 1 contains paired measurements of arsenic in 950 groundwater wells. Arsenic was measured using a field kit and in the lab by inductively coupled plasma mass spectrometry (Van Geen et al., 2014).
Dataset 2 contains >6500 lab measured groundwater arsenic concentrations. The dataset was originally analyzed in van Geen et al., 2003.
