choeller Diagram with Samples from NWC Wellschoeller Diagram with Samples from NWC Wells
bout 28 samples are displayed on this cumulative diagram. It shows the range of values (in parts per million) for major ions. The National Water Commission (NWC) wells are used for water supply (drinking and domestic) of villages and towns. The comparison between maximum field values and maximum permissible concentrations (by WHO standards) is shown in table below.
While sulphates are not a problem, the chloride content is higher than permissible in three wells used for water supply. The location of these wells is shown in the map below.
