Department of Biotechnology, St. Peter’s College, Kolenchery, has conducted a ‘water quality checking Campaign’ on well waters and other drinking water sources in the severely flood-affected area of Kadmattom Village. A team of M. Sc Biotechnology Students of 2017-2019 Batch, teachers and lab assistant of the Department visited 23 houses at kadamattom (a village on the bank of Muvattupuzha river), and collected drinking water samples from wells which were contaminated by the flood water. Analysis was done at the Microbiology lab. A report was prepared for each water sample that included total coliform count, pH, TDS, salinity and conductivity and organoleptic properties. Coliform count was found to be high at above the desirable limit in 17 wells. Chlorination was suggested for these wells and packets of bleaching powder were supplied. Students helped to chlorinate the well waters. Super chlorination was performed for three wells. As low acidity at undesirable levels was found in three wells, where hydrated lime treatment was recommended.
