Who monitors the quantity and quality of ground water
Answers
Knowing the groundwater level is important for several reasons, including understanding aquifer levels under static conditions and pumping conditions, determining how the levels interact with local surface water sources, and understanding how surface development has impacted the aquifer.
Groundwater extraction from pumping
Pumping groundwater for surface use has the greatest effect on the amount of groundwater stored in an aquifer and the rate at which it refills or recharges. The most severe consequence of excessive groundwater pumping is that the water table can be lowered. It is important to monitor and understand the groundwater levels prior to drilling any wells which will have significant drawdown of the aquifer because the water table levels will give a good idea of the impact of the new well. For water to be withdrawn from the ground, water must be pumped from a well that reaches below the water table. The data collected by monitoring groundwater can be used to determine the amount of groundwater that can safely be withdrawn before no more water can be pumped. In this way, local water managers can prevent wells from going dry and prevent the movement of poorer quality groundwater into the aquifer. If groundwater levels decline too far, then the well owner might have to deepen the well, drill a new well, or, at least, attempt to lower the pump which could become very expensive for the owner. In addition to the cost of increasing the depth of the well, drilling a new well, or moving the pump down as the depth to water increases, the water must now be lifted higher to reach the surface. If pumps are used to lift the water (as opposed to artesian wells), more energy is required to drive the pump which results in more expensive water. Eventually a deep well could become prohibitively expensive to pump water from.
