Summary

This dataset includes data collected to validate a method of analysis for arsenic species As(III), As(V), dimethylarsinate (DMA), and monomethylarsonate (MMA) in surface water and groundwater samples. It also includes site information and water chemistry for samples used in the validation and used for other studies of arsenic species in groundwater. It includes speciation data measured at multiple time points to establish or verify hold times and stability of As species in surface water and groundwater samples.

Purpose

The data were collected for a fourfold purpose: 1)To assess the validity of an LC/ICP-MS/MS method for the determination of As(III), As(V), DMA, and MMA in surface water and groundwater samples and establish figures of merit; 2) to verify stability, preservation, and holding times for As(III), As(V), DMA, and MMA in environmental samples and laboratory standards under varied collection, preservation, and storage conditions; 3) to study the behavior of dissolved arsenic and As(III) and As(V) as redox conditions change with flow in commercial and private drinking water wells in New Hampshire; and 4) to evaluate the performance of a commercial field sensor for the determination of As(III) and total arsenic, in cooperation with the Environmental Health Mission Area of the US Geological Survey.
