Groundwater Recharge using Stormwater

I need advice on recharging #Groundwater  with #Stormwater

What is the most efficient technology for artificially moving the surface water down to groundwater?

Is there a risk of polluting the groundwater resources?  

Is there a technology that removes Total Suspended Solids (TSS) and dissolved harmful constituents such as oil, heavy metals and other contaminants which are part of the  #Stormwater Runoff  while recharging? 

How can Low-impact development (LID) best be implemented in groundwater recharge?
