Department of botany analysed the water quality of Sasthamcotta lake under the supervision of Ms.Lekshmy Sreekumar . Eight students from the department of botany participated in thwe study, conducted on 11-02-2018.Samples from different localities of Sasthamkotta Panchayath and different parts of the lake was analyzed for coliform bacteria. Altogether twenty samples were analyzed for preliminary screening. The result indicated that the water tested was contaminated highly with fecal materials.Water pollution caused by fecal contamination is a serious problem due to the potential for contracting diseases from pathogens. The presence of pathogens is determined with indirect evidence by testing for an “indicator” organism such as coliform bacteria. Coliforms are easy to identify, are usually present in larger numbers . As a result, testing for coliform bacteria can be a reasonable indication of whether other pathogenic bacteria are present.
Thus, the public people around the locality were advised to take proper measures to solve the coliform problem. It can sometimes be solved with relatively simple actions like chlorination, boiling, and adding disinfectants. Thus awareness programs were conducted to revive the quality of Sasthamcotta lake.
