Groundwater geochemical data from two sites in Cambodia, southeast of Phnom Penh, 2019 - 2020
These are groundwater geochemical data taken from two sites in the Kien Svay district of northern Kandal Province, Cambodia, southeast of Phnom Penh. These sites are referred to as “clay-dominated” and “sand-dominated” in reference to the known lithology and are known for high arsenic concentrations (Richards et al., 2017). Each site contained four 18 m boreholes installed in January 2019 using manual drilling described in Richards et al (2015), spaced evenly about ~1.5 m apart. The boreholes that were located at the clay-dominated site are referred to NB01, NB02, NB03 and NB04. The boreholes that were located at the sand-dominated site are referred to as NB05, NB06, NB07 and NB08. Two sampling campaigns were carried out: 6th-12th May 2019 (pre-monsoon season), and 27th-31st January 2020 (post-monsoon season). References: Richards, L.

Groundwater sample collection began upon stabilization of the ORP (which was typically after about 120 L, or 6 - 7 borehole volumes, of water had been removed from the boreholes). Surface water samples were collected from wetland/pond near the clay-dominated site. In each sampling campaign, duplicate samples were taken from each borehole, by filtration through 0.45 µm glass microfiber syringe filters (Whatman/GE Healthcare, UK), stored in acid-washed and furnaced 100 mL glass serum bottles, sealed with rubber butyl stoppers secured with an aluminium crimp, kept stored at 4°C until analysis, within 4 weeks of collection. Subsamples were acidified to pH 2 using trace grade nitric acid (BDH Aristar, UK) for elemental analysis using inductively coupled plasma atomic emission spectrometry (Perkin-Elmer Optima 5300 dual view; iron) and/or inductively coupled plasma-mass spectrometry (Agilent 7500cx; arsenic). Subsamples were used to measure dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC) using the high-temperature catalytic oxidation method as described previously (Nixon et al., 2018). All the geochemical measurements were done at the Manchester Analytical Geochemistry Unit at The University of Manchester. References: Nixon, S. L.; van Dongen, B. E.; Boothman, C.; Small, J.
