The document discusses groundwater quality analysis in Penumuru Mandal, Chittoor District, Andhra Pradesh, India. 20 water samples were collected from bore wells and analyzed. Parameters like pH, EC, TH, DO, Na, K, and alkalinity were within permissible limits except for total hardness, sodium, and alkalinity which were higher. The study concluded that groundwater quality is suitable for domestic use but not industrial use due to hardness. Excessive pumping has led to overexploitation of groundwater resources in some areas. Artificial recharge and awareness programs were recommended for sustainable groundwater management.
