Samples were collected using High-Density Polyethylene (HDPE) amber bottles, and filtered in the field laboratory by vaccum filtration (polysulphone apparatus) and 0.22 μm Polyvinylidene difluoride (PVDF) membrane. The filtration unit was triple rinsed with Deionized (DI) water and sample for each use. Two 25 ml polyethylene scintillation vials were filled for each sample and kept refrigerated until analysis. Samples were analysed for cations (Na+, K+, NH4+, Ca2+, and Mg2+) and anions (Cl-, Br-, NO2-, SO42-, NO3-, PO43-) by liquid ion chromatography with a Dionex ICS-5000 system. The ion chromatograph was equipped with an ASRS Ultra suppressor and AS18 analytical column for anions, and a CSRS Ultra suppressor and CS12A analytical column for cations.
Concentrations are in ppm, n.a. indicates values below detection.
