ASSESSMENT OF GROUND WATER QUALITY WITH SPECIAL REFERENCE TO TOTAL COLIFORM OF A RURAL AREA IN CHENGANNUR TALUK IN KERALA

摘要

Physico-chemical and bacteriological characteristics of quality of different ground waters in a rural area of Chengannur Taluk in Kerala were estimated in the laboratory, following methods of APHA 1992. A questionnaire was prepared based on the position and type of latrines, duration of use, number of persons using etc. and distributed in the area of study. Out of ten samples studied, all had some parameters above the permissible level. Microbial analyses revealed that some ground water was most contaminated than the rest. This is a cause for concern for those consuming the well water directly for drinking purpose.
