Abstract:

In this study the hydrochemical characteristics of the Manchalapur tank water or lake was analysed for its suitability for domestic, fish rearing and irrigation purposes. A total of 10 water samples each were drawn from the inlet, outlet and two other locations in the water spread area of the tank and analysed for TDS, pH, EC, BOD5, COD, major ions, detergent and pathogen contamination in three distinct seasons, viz. pre-monsoon, monsoon and post-monsoon, based on standard methods. The concentration of pollutants had varied within these seasons with TDS, pH, EC, COD, and the major ions measuring the highest in the pre-monsoon season when tank had received undiluted sewage from the Raichur city. The order of dominance of ions in water samples of this study area is Na+> Ca2+> Mg2+> K+ and Cl-> SO¬42-> Nitrate > PO43->HCO3->CO32- as estimated in the pre-monsoon season, and Na+> Ca2+> K+>Mg2+ and Cl-> SO¬42-> Nitrate > PO43->HCO3->CO32- in both the monsoon and post-monsoon seasons. According to pH values, tank water is alkaline during all three sampling seasons. The weighted water quality index was used to assess the suitability of tank water for domestic purposes. The ∑WQI was estimated as 24, 30 and 26 in the pre-monsoon, monsoon and post-monsoon seasons respectively, indicating a critical water quality condition and thus raising high objection against the use of the tank water for drinking purpose. However, the tank water was found most suitable for irrigation in the monsoon season as compared to other seasons since it poses no or limited salinity and sodium hazards. This is corroborated by TDS, EC, major ions, SAR and Na% values measured in the monsoon season which are all within permissible limits. On the other hand, high BOD5, COD, excess in NPK present in water system, surfactants and pathogen contamination rendered tank water unsupportive for fish and thus may impair aquatic life. Hence, other than irrigation (even that only in the monsoon season), the Manchalapur tank water is unsuitable for drinking and fish propagation.
