The water deluge system has been in operation for all launches save the first and has been functioning well, protecting the pad from damage. It uses drinking-quality water and outflow has been sampled after each launch, with negligible traces of contaminants detected.
There was a disagreement between the Texas Commission on Environmental Quality and the US EPA about the specific type of permit that SpaceX needed from TCEQ for the deluge system but that was a paperwork/documentation issue only.
