Secondary stage effluent may be taken for recharge inyo aquifers after ensuring that the water's - physical.chemical.micro-biological standard conform to municipal potable water standards.
The ground regime has a method of doing a process of treatment - SAT Soil Aquifer Treatment. This is very efficient the ground layers behave as filters.
But if these layers get contaminated with pollutants, it is very difficult to clean the regimes.
The above may be noted.
Well wishes.
