A Study on Water Quality Parameters of Water Supply in Sylhet City Corporation Area

Abstract

An investigation was carried out to assess the water quality parameters of water supplied by Sylhet City Corporation (SCC).The supplied water quality is at risk to deteriorate during its flow through the delivery system and/or due to the possibility of high elemental concentration in ground water. In SCC, there are 23 pumps available that continually supply water for city dwellers. The parameter analyzed are like pH, turbidity, hardness, chloride, TDS (Total dissolved solid), arsenic, iron, FC (Fecal Coliform) and TC (Total Coliform). All results are compared with the World Health Organization (WHO), Bangladesh Standard (BD) and the Indian Standard Institute (ISI).The investigation discovers that the value of turbidity and iron in the location of Christian Mission designated by S-11 crosses the all three standard. The measurement of TDS and chloride shows that the values are within the safe limit. Analysis of arsenic and FC water quality parameter revealed that there are no arsenic and fecal coliform contamination. The water treatment facilities of SCC have to be enhanced; necessary steps should be taken to reduce the contamination and adequate treatment facility should be promoted.
