Abstract: The primary polluter of the environment is the tannery industry and there is a strong possibility of water and soil pollution due to discharge of informal wastes.More than 250 chemicals are used in the production of leather and other toxins like toxic organic chlorinated phenols, toxic CrVI and other toxic pollutants such as sulphide, phenolic compound, magnesium, sodium, potassium, lead, zinc, pesticide residues, mineral salt, dye releases a complex mixture of pollutants. CrVI and chlorinated phenol toxic to human as well as biota or ecosystem or environment is the basic major sewage. Chromium is the most dangerous. It is very popular in the tanning industry because it strengthens leather. Its waste from is hexavalent chromium or CrVI- people have to face diseases like lung cancer, headache, dizziness, allergic reaction, asthma and liver failure etc.Tannery water contain hazardous pollutants with mainly dark brown colour, foul smell and dangerous pollution with some waste material and persistent organic compounds in various quantities. Excess amount of this water mix with the soil and has adverse effect on the plants and vegetables growing it. The waste material generated from tannery industries can be treated in many ways- there is a need to upgrade the CETP (common effluent treatment plant) in industrial area so that the higher quantity of effluents can be treated. CETP (common effluent treatment plant) plant should be checked monthly. Instead of giving the responsibility of monitoring the treatment plants to the water corporation, cooperative societies themselves should be formed and they can manage the process of sewage treatment. Most of the tanneries in industrial area are chrome tannery, hence chrome recovery plant should be set up.
