Abstract

Perchlorate has been increasingly reported in ground waters of industrial Kerala. The Perchlorate (ClO4–), is a manufactured chemical used as the main ingredient of rocket fuel, safety flares, matches, fireworks, batteries and vehicle air bags. Presence of perchlorate in drinking water may damage the thyroid gland, which controls growth and metabolism. The objectives identified are to study the temporal variation of Perchlorate in ground waters of industrial areas in Kerala, variation in shallow and deep aquifers, aerial distribution of Perchlorate in ground waters of industrial areas in Kerala, find out the suitability of Perchlorate containing ground water in the area for various purposes and to compile the base line information on perchlorate in ground waters of all industrial areas in Kerala.
