Aquifers have a natural recharge rate. However, some aquifers rely on fossil water for their primary (or even sole) water supply. When water in a well is pulled from these aquifers faster than they can replenish, the level drops and they eventually "dry up" (or the water table drops below the bottom of the well, at least). In the case of aquifers with no recharge, such as fossil water, it seems that the water could literally be used up so that the aquifer becomes completely dry.
For these fossil water aquifers, is there any known technique to recharge them? Since they're labelled as a non-renewable resource, I presume the answer is "no", but I'd like to get a better understanding of this.
For aquifers with a low recharge rate and a severly dropped water table, is there any known way to increase their recharge rate?
