Comparative Study of Water Quality Parameters along NH, SH and Link Road of Shivalik Foothills in Himachal Pradesh

A study was conducted to evaluate the spatial and seasonal variation in quality of surface water sources along national highway, state highway link road. Physicochemical properties were estimated using samples collected during pre-monsoon, monsoon, post-monsoon seasons year 2018 2019. The parameters (pH, EC, Turbidity, TDS, BOD, COD, Cl-, NO3- heavy metals) calculated. investigation revealed that pH (6.91-7.35), EC (0.17-0.29 dS m-1), TDS (140.12-175.54 mg l-1), Turbidity (2.34-3.87 NTU), BOD (2.25-2.89 COD (13.49-20.19 Cl- (14.36-30.15 (3.12-4.89 l-1) various metals within permissible limits varied significantly (p<0.05) on variations. Maximum effects vehicular emissions roadside bodies observed at NH followed by SH minimum noticed LR. Among seasons, maximum values pre-monsoon season monsoon then post-monsoon.
