PHYSICOCHEMICAL CHARACTERISTICS OF GROUND WATER OF DEOLALI PRAVARA AREA, DISTRICT AHMEDNAGAR, MAHARASHTRA

摘要

In the present investigation attempts has been made to study physicochemical characteristics of ground water of Deolali Pravara area. Ground water is no more considered to be non-polluted. The investigation was highlighted and to assess the suitability of water for drinking. The water samples were collected from three wells. The samples were analyzed for pH, temperature (degrees C), electrical conductance (EC), total alkalinity (TA), total hardness(TH), calcium(Ca++), magnesium(Mg+), chloride (Cl-), sodium (Na+), potassium (K+), sulphide (So(4)(-)) and nitrates (No-3(-))etc. The average value of pH was ranged 6.0 to 7.0, Temperature 15.33 to 16.30, electrical conductivity (EC) 650.00 to 855.32 mu mho/cm, total alkalinity (TA) 49.10 to 55.13 mg/L, total hardness (TH) 23.5 to 23.33, calcium(Ca++) 8.2 to 16.5 mg/L, magnesium (Mg+) 4.99 to 8.16 mg/L, chloride (Cl-) 106 to 232 mg/L, Sodium (Na+) 2.9 to 4.63, potassium (K+) 4.46 to 4.76, sulphide (SO4-) 2.43 to 3.00 and nitrates (NO3-) 1.55 to 1.66 etc. They were compared with standard value of APHA and WHO and classified according to Durfer and Beker's method. The results show that, water of Deolali Pravara area is within permissible limit according to observations.
