Physico-Chemical Properties of Different Water Bodies of Manipur

Abstract

Assessment of physico-chemical parameters were carried out during April 2016 to March 2017 from ten different sites viz. site I (Langol bore well), site II (Thangmeiband pond) from Imphal west district; site III (Loktak lake), site IV (Thongjaorok river) of Bishnupur district; site V (Maha river), VI (stream), VII (pond) of Chandel district; site VIII (stream), IX (chuya spring), and X (kulu canal) from Senapati district of Manipur, India. Water quality parameters such as Temperature, pH, Dissolved oxygen, Total alkalinity, Chloride and Nitrate were analyzed. The temperature ranged from 16-29oC showing higher in summer.The pH value was found to be ranged from 5.9 to 8.2. It’s indicating that pH is neutral to acidic in nature. The value of DO ranges from 3.2 to 12.8 ppm being highest in site ix (chuya spring of urkhul district). Total alkalinity was found to be higher in winter and low in summer season. The values of total Alkalinity range from 20 to 190 ppm. Chloride content varies from 10ppm-25ppm.The chloride content reached their maximum value during summer. Nitrate concentration range from 0.153-0.548 ppm due to run off water from agriculture field, municipal sewage from market place and other effluents containing nitrogen species. The results indicated that most of the physico-chemical parameters from ten different sites of Manipur districts were within the WHO limits for drinking water and, therefore may be suitable for domestic purposes. This conclusion is based on 6 parameters tested. It is possible that water quality would be worse if more parameters will be examined, eg. Bacteriology.
