Water Quality Analytics

The water quality analytics (WQA) group of the clean water program (CWP) is tasked to carry out laboratory analyses of physical, chemical and microbiological parameters that indicate the quality of water pre- and post- aquifer recharge. Apart from general water quality parameters (i.e. temperature, pH, conductivity etc), target monitoring parameters were set based on the objective to assess the effectiveness of aquifer storage as a means of reducing possible traces of contaminants in the recharged water. In addition to using standard methods recommended by the American Public Health Association (APHA) and the United States Environmental Protection Agency (USEPA), various chemical and microbiological methods are also being developed to improve the efficiency and quality of analyses. These include the use of HPLC/MS-MS techniques to detect organics at trace levels, as well as flow cytometry for rapid detection and enumeration of microorganisms.
