Abstract
Multi-level sampling wells are installed to monitor the spatial and temporal changes in hydro-salinity in fresh-saline aquifer under different pumping regimes. Sampling wells consist of 5 mm diameter high density polyethylene tubes opened at different depths ranging from 5 to 75 m. Lower end of each tube is perforated to allow lateral entry of the water. Water samples are collected using suction bottles attached to each tube. The storage effect during sampling is minimised by disposing off the already existing water in each tube. The sampling well is cost effective, easy to install and is suitable for collecting unmixed water samples at different depths in unconfined sand aquifers.
