Abstract
The present paper includes an assessment of the quality ofPechiparai dam situated in Kanyakumari district.The quality water affects the human health.The dam water is used for irrigation drinking and fishing .The dam provides water for more than 50% population for agriculture and other activities.The analysis givesus a knowledge on quality of water. The water samples were analysed from 2010 June to May 2011. Water is analyzed for seasonal variation in temperature,pH,electrical conductivity,dissolved oxygen,chloride,total hardness, total alkalinity, biochemical oxygen demand, total dissolved solids, chemical oxygen demand.The results reveal that .The range of seasonal variation in different parameters was temperature 27o C to 30.2oC, Ph 6.99 to7.68, electrical conductivity 25 to 84 (μmho/cm),total hardness 8.0 to 22 mg/lit. Dissolved oxygen 5.20 mg/lit to 6.29 mg/lit. Biochemical oxygen demand 4.54 to 5.65 mg/lit.Chloride 3mg/lit to 5mg/lit. Total alkalinity 9 mg/lit to 16mg/lit. Total dissolved solids 20 to 33 mg/lit. chemical oxygen demand 9to 19 mg/lit. All the parameters are within the permissible limit recommended by WHO.
