The WSERU laboratory is responsible for:
- Collection of rainfall;
- Collection of water samples;
- Analysis of samples for a range HCO3-of physical, chemical and biological parameters (including pH, EC, D0, temperature, major cations and anions (Ca+2, Mg+2,,Na+ and K+ HCO3-,CO3-,SO4-2Cl- ,NO3-,F- ,Br-,I-,PO4-3 ,SiO2), Total and Faecal Coliform and heavy metals (Fe, Cu, Mn, Pb, Cd, Zn). Monitoring of rainfall data, within the context of historical records available and continuous updating from laboratory gauges and other stations in the Southern West Bank; and
- Evaluation of data to determine water quality and the cause and source of any pollution observed.
The samples were analyzed according to the standard methods for the examination of water and wastewater of the American Health Association (1995).
In addition, direct measurements were made at each site with the WSERU field system, a Mettler Toledo set of probes, giving readings for temperature, electrical conductivity (EC), total dissolved solids (TDS) and pH.
