Assessment of Water quality in terms of physico – chemical parameters of East Godavari mangrove ecosystem (Coringa Wildlife Sanctuary) East Godavari, Andhra Pradesh, India.

Abstract

A study was conducted on physico-chemical parameters of water from the estuary region in Coringa Wildlife Sanctuary. Physico-chemical parameters play an important role in the structuring the fish species and other aquatic organisms in mangrove swamp, estuaries and coastal areas. The baseline study was carried out for two successive years that is from January 2015 to December 2016 respectively. Monthly water samples were collected and 10 water parameters were analyzed. Data on temperature and pH were obtained from the field using mercury-in-glass thermometer and portable pH pen. Dissolved Oxygen, Salinity, Alkalinity, Hardness, Calcium and Magnesium were analyzed by using the standard protocols. Temperature varied between 33.8-26; pH, 8.5-7.15; salinity 24-0; dissolved oxygen 7.8-4; Ammonia 1.2 -0.05; alkalinity, 340-80; Nitrite 1 – 0.01; Hardness 3500-110;Calcium 250-80; Magnesium 450-180. The water parameters favored the growth of the aquatic organisms. However, due to the ever increasing discharge of the effluents from the industries, municipality drainages and the aqua culture ponds contribute to the pollution of the estuarine ecosystems. This study is baseline data towards future ecological study, conservation and management of the resources in the East Godavari estuarine ecosystem. Copy Right, IJAR, 2016,. All rights reserved.
