“…The lower pH values have a tendency to make water corrosive, and higher pH value leads to taste grievance and harmful impact on the eyes and skin (Ravikumar et al 2013). pH value in groundwater samples ranging from 7.29 to 8.17, 7.33-8.45, and 6.29-7.20 during pre-monsoon, monsoon, and post-monsoon seasons, respectively, indicates the alkaline nature and slightly acidic in post-monsoon season.…”

“…Total dissolved solids indicate the various types of minerals present in water in dissolved form consisting of calcium, magnesium, sodium, potassium, carbonates, bicarbonates, chlorides, sulfate, phosphate, silica, iron, and small amounts of organic matters (Gnanachandrasamy et al 2014;Ravikumar et al 2013). TDS in the study area varies from 817 to 4340 mg/L (pre-monsoon), 915 to 4243 mg/L (monsoon), and 1094 to 4346 mg/L (postmonsoon).…”

The hydrochemical study of groundwater in Karur district of the Amaravathi River basin has been carried out to assess the major ion chemistry and groundwater quality for domestic and drinking purposes. Twenty-four groundwater samples were collected, processed, and analyzed for various physico-chemical parameters such as pH; electrical conductivity; total dissolved solids; total hardness; cations such as calcium, magnesium, sodium, and potassium; anions such as bicarbonate, chloride, sulfate, fluoride, nitrate, and phosphate in the laboratory using the standard methods given by the American Public Health Association (Standard methods for the examination of water and wastewater, 21st edn. American Public Health Association, Washington DC, 2005). For quality assessment, the results were compared with water quality standards prescribed by the Bureau of Indian standards (Indian standards specification for drinking water 15:10500. Bureau of Indian Standards, New Delhi, 2003) Concerning water for irrigation purposes, parameters such as percent sodium (% Na), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), chloro-alkaline indices (CAI I and CAI II), permeability index (PI), magnesium hazard (MH), Kelley's ratio (KR), USSL diagram, Gibbs' ratio (GR), and Wilcox diagram were calculated on the basis of chemical data to evaluate the current status of groundwater in the Amaravathi River basin. Parameters like MH (74 %), KR (75 %), RSC (95 %), and PI (69 %) in all three seasons indicate that the samples are suitable for irrigation and remaining are unsuitable. From USSL diagram, the result reveals that the samples fall in C3-S1 and C4-S1 indicate high to very high-salinity and lowsodium hazards. Wilcox diagram revealed out of 24 samples, sample no. 7, 8, and 11 in pre-monsoon, monsoon, and postmonsoon seasons fall under doubtful to unsuitable and 9 fall under unsuitable zone. The positive CAI values in 66 % samples in all three seasons indicate reverse ion exchange mechanism. The present study may be helpful for further studies concerning water quality issues in this area, where groundwater is a vital for drinking and other activities.

“…Selvam et al (37) evaluated the water quality index of groundwater resources around the coastal city of Tuticorin in southern India and concluded that the groundwater quality was impaired by man-made activities. Ravikumar et al studied the water quality index to determine the quality of surface water of Mallathahalli Lake in India and showed that the lake water fell into the poor water category (38).…”

Background: Internal corrosion and the formation of scale in water distribution pipes are the most important problems for an urban water distribution system. Physical, chemical, or biological factors can lead to these two processes. Internal corrosion and scale formation can impact health, economy, and aesthetics. This study assessed the physicochemical quality parameters and evaluated the potential for corrosion and scale formation in drinking water at the distribution systems of 5 selected cities in Bushehr province (Kangan, Dashtestan, Dashti, Bushehr, and Ganaveh) from 2009-2012. Methods: This study was carried out based on laboratory data collected from monthly samplings of tap water in the Water and Wastewater Company of Bushehr province during the years 2009-2012. Internal corrosion and scale formation rates were calculated using the Ryznar, Langelier, Aggressive, and Puckorius indices. Results:The results of the Ryznar, Puckorius, Aggressive and Langelier indices indicated that the drinking water in the 5 selected cities of Bushehr province was corrosive. Moreover, the majority of parameters used to determine water quality exceeded Iran's national standards. Conclusion: It is concluded that there is problem of water corrosion and scaling in drinking water of distribution systems in selected cities.

“…They regulate the urban climate (Benjamin, 1996) and also have a prominent effect on ground water quality and ground water table (Ravikumar, 2013). Lakes have environmental significance as sources of surface and ground water recharge, maintain nutrient and energy exchange with watersheds and air sheds and support diversified aquatic life.…”
