Brief Description (Abstract):

In accordance to environmental protocol to Antarctic treaty, monitoring of surface waters and wastewaters around Indian Antarctic station Maitri was carried out as a part of EI A studies during austral summer of 1993-94. Surface water sources like Zub lake, its feeding glacier waters, control lake and a seepage channel meeting to Zub lake were identified and samples were analysed for physical, inorganics (chloride, sulphate), nutrients (nitrate, phosphate), organics (TOC, hydrocarbon) and selective heavy metal levels. The results indicate that barring seepage water, all the samples possessed characteristics for drinking water qualities stipulated by WHO. However, glacier water at western side of the station showed an increasing trend of nutrients, dissolved solids, EC and heavy metals as compared to those to eastern side of the station. The above parameters increased substantially in seepage water indicating due attention to this channel of unknown origin.

Status: Completed

Purpose: The Indian permanent station Maitri is located at latitude 70?4553S &amp longitude 11?443E and situated on Schirmacher hills of East Antarctica. The station has been functioning smoothly since its commissioning in the austral summer of 1988-89 and has withstood the test of the time. While establishing this station, various environmental aspects had been taken into consideration to ensure that as little a damage to the environment is done. There are innumerable number of freshwater lakes in the Antarctic continent. The Zub lake, formally known as Priyadarshini lake, covering an area of approximately 0.35 sq km and located close to N-E side of Maitri station has been taken into consideration for its physico-chemical characteristics as it is the only source of drinking water to the inmates of Maitri station. The locations of summer camp urinal and bathroom near the lake and a seepage channel emerging at higher elevation close to wastewater ponds.
