DRINKING WATER QUALITY
At present, the standard for treated drinking water is that less than 1% of the samples will be positive for coliform organisms. In most years there are 20 to 30 incidents in which at least two people become ill from the same water source, and the total number of illnesses is annually 2000 to 3000.
Water quality has a significant impact on water supply and oftentimes determines supply options.
Poor quality of water is one of the main factors turning good soil into saline or sodic. High subsoil water table, aridity, seepage from canals, poor drainage, back water flow, intrusion of sea water also leads to salinity and sodicity.
