Physico-chemical characteristics of the ground water table after monsoon: a case study at central Travancore in Kerala

Abstract

Water quality plays an important role in maintaining plant and animal life. Lack of good quality drinking water and water for sanitation cause health problems. Water quality characteristics arise from a group of physical, chemical and biological factors. The dynamic balance of the aquatic system can be destroyed by human activities resulting in water pollution.Well water has traditionally considered as a safe resource of water for consumption without treatment and extensively used for individual water supply in rural and many urban areas.In this paper a preliminary analysis is done to explore the water quality of selected wells in order to correlate the effect of pollution on water quality at these locations. Water samples are collected from different regions of Vazhappally area located on central travancore of Kerala. These sites are important because people depend only on well water for drinking purpose. The samples are collected from ten locations and analyzed for chemical parameters such as pH, conductivity, salinity, turbidity, acidity, alkainity, hardness, total phosphates, dissolved oxygen, biological oxygen demand, total dissolved solids and Iron content. Samples are also analysed for coliform bacteria which cause pathogenic diseases. Remarkable differences are observed mainly in biological oxygen demand, acidity and hardness. Finally, an attempt has been done to correlate the observed chemical parameters and the waterquality standards.

Assessment of surface water quality using hierarchical cluster analysis

“…So instead of monitoring ten sites, only three sites could be selected in future spatial sampling strategy without affecting the result. The reduction in sampling sites in the monitoring network will be more economical without losing any significance of the outcome (Bajpai et al, 2013;Vishnu et al, 2014;Sreenivasulu et al, 2014).…”

“…In many cases, water is usually drawn from aquifers through wells, and has traditionally been considered safe for use. Vishnu, et al (2014) describe how the dynamic balance of an aquatic system can be seriously affected by human activities. They analyze the water quality from a rural area of the state of Kerala in India for different physiochemical properties, and evaluate them against existing water quality parameters and standards.…”
