Our water resources are of major environmental, social, health and economic value. The health of these resources, which is closely linked to the surrounding environment and is determined by the quality of waters. Water quality often declines where there is excessive use of land and water resources. Moreover, the pollutions from urban regions, industries, recreational purpose, spiritual purpose, and agriculture lead to a decline in the quality of water. The poor quality of water can have a serious effect on the health of people and the ecosystem as a whole. In order to prevent problems, one needs to understand how human activities affect these water resources.
VNC plays a lead role important role in monitoring the quality of drinking water in urban areas. We have also begun to assess the health of wetlands and understand the impacts of invasive species like Water hyacinth on water quality and aquatic ecosystem. These approaches would support water managers and other agencies to manage potential impacts on water sources.
