Short summary
As groundwater serves as the principal source of water worldwide, its quality is of paramount importance. In this study, the evolution of groundwater quality in California is assessed using the Water Quality Index & Weighted Index Overlay Analysis methods. Several water quality parameters are considered for the analysis, and the results from both methods are compared. The study shows that in most parts of California, groundwater quality is potable, as per WHO guidelines, except in a few places.
