Sources Of Groundwater:-- 1.Meteoric water is the water derived from precipitation (snow and rain). This includes water from lakes, rivers, and icemelts, which all originate from precipitation indirectly. 2. Connate water is the water that were trapped in the pores of sedimentary rocks as they were deposited. These liquids are largely composed of water, but also contain many mineral components as ions in solution. 3.Magmatic water or juvenile water is water that exists within, and in equilibrium with, a magma or water-rich volatile fluids that are derived from a magma. This magmatic water is released to the atmosphere during a volcanic eruption. & The study of water flow in aquifers and the characterization of aquifers is called hydrogeology Aquifers is defined as a pores or permeable geological formation in which we can stored water and yield the water in sufficient quantity when we required. An aquitard is a zone within the earth that restricts the flow of groundwater from one aquifer to another. Aquiclude is defined as a pores or permeable geological formation in which we can store water but we can yield when we required. Aquifuge is also a geological formation in which we neither store nor yield water when we required.
