Water and soil lab

The Water and Soil Lab at ATREE was established in April 2013.The Lab provides facilities to carry out research on water quality issues. The laboratory is well equipped to measure and quantify various physical, chemical and biological pollutants in water and soil. The lab consists of two units – Wet chemistry and Microbiology. In wet chemistry unit we measure physical and chemical contaminants present in water. In Microbiology unit, as the name suggest we carry out tests to quantify level of bacteriological contamination in water. This lab had helped in successful execution of three major projects and currently, two projects are being executed, which involve analysis of water and wastewater quality.
