Ground Water Quality Evaluation of Karkala Town
Ground Water Quality Evaluation of Karkala Town Water Quality Index (WQI) computed on the basis of certain hydrogeochemical parameters is one of the most effective tools for understanding the overall quality and suitability of water for drinking, irrigation and industrial purposes. The same spatial variation can demonstrate the percentage of pollution in an area.
Groundwater is the major source for drinking, irrigation, and industrial purposes in many parts of the world. Safe drinking water is now only a dream for all human beings. Hydrogeochemical analysis of groundwater has become more essential due to the recent development in urbanization, industrialization and modern agricultural practices.
According to the Water-Aid works of the British Geological Survey (2000), southern India’s groundwater quality is heavily dependent on rock geology and climate, but can also be affected by pollution in parts, particularly from agricultural and industrial sources.
Anthropogenic activity, viz. Agriculture, industry, urban development, increased use of water resources and atmospheric input also influence groundwater quality. In developing countries, infant mortality is mostly caused by drinking contaminated water.
The Water Quality Index computed for the study area shows that for drinking purposes the groundwater quality in the area is of poor to very poor quality. Quality degradation indicates the pollution caused by the trend in urbanization and the area’s improper development.
To solve this area’s water quality problem, it is necessary to have a proper sustainable water quality management plan for the study area. Unless proper management techniques are adopted to improve groundwater quality, the aquifers in this area will continue to be degraded.
