Learn MoreDroughts, seasonal variations in rainfall, and pumping affect the height of the under groundwater levels. If a well is pumped at a faster rate than the aquifer around it is recharged by precipitation or other underground flow, then water levels in the well can be lowered. This can happen during drought, due to the extreme deficit of rain.
