Water is prime natural resources fulfilling our needs in a precious assets. We must act to preserve and utilize every drop of water. Water resources can be assessed on the basis of surface and subsurface water bodies. The impact of climate change on ground water has been studied much less than the impact on surface waters. Ground water reacts to climate change mainly due to change in ground water recharge, but also change in river level in response to increase in mean Temperature, precipitation, variability and sea level as mean precipitations. Changing land use pattern, due to increasing, urbanization, industrialization and agriculture activities are serious issues that causing increase ground water withdrawal resulting in depletion of ground water resources and mining of ground water resources, along with deterioration of water quality. Rainfall is highly irregular and erratic and declining year to year due to change climatic conditions, as a result of serious deforestation, global warming, etc. Human health is affected by the change in biodiversity and ecosystem. Keywords: climate change, heat waves, water quality, human health.
