A Study of the Physiochemical Parameters of Two Lakes in Vellore District, Tamilnadu State, India

Abstract

A comparative analysis was carried out from January 2019 to December 2019, to examine the seasonal changes in two lakes. The study focused on several parameters, including Color, odour, turbidity, electrical conductivity, pH, alkalinity, total hardness, calcium, magnesium, ammonia, nitrite, nitrate, chloride, fluoride, sulfate, phosphate, BOD, and COD. During the study, it was observed that Vanderthangal Lake had higher concentrations of ammonia, fluoride, and phosphate compared to Dharapadavedu Lake, indicating that it was more polluted. The findings also revealed that the ammonia, fluoride, and phosphate levels in Vanderthangal exceeded the standard limits. Furthermore, there was significant seasonal variation in the physicochemical parameters throughout the entire study period
