Water Sources Water in reservoirs and water plants can come from several different areas. Some types of water bubble up from springs, but most is piped up from deep underground reserves using pumps and wells that reach down to the water table. This water is usually rain water that fell at nearby mountains or hills, then ran down under the force of gravity until it seeped underground. Along the way, this water picks up dirt and minerals from many different places, and when humans pump the water up or catch it in reservoirs for their own uses, the minerals are carried with it. Groundwater already pooled below the soil can gather more minerals through the new runoffs that bring many different kinds of chemicals and particles to add to the mix.
