Arsenic in groundwater at construction site

[iheartwater]

My boss just told me that there are high amounts of arsenic in the groundwater at one of our construction sites and wants me to research other construction projects that faced similar issues.
We are not building anything residential, the the grounndwater does not need to be permanently treated we just can't allow arsenic infected water to the surface and we are constructing a pipe through the area.
Any suggestions ON where in the web I could find examples of similar situations?
or any suggestions on affordable means of temporary groundwater treatment?

The meaning depends on whether there is an industrial source or whether the arsenic is consistent with natural levels. Just because the water table has arsenic over some drainking water threashold, doesn't mean it's "contamination" - it could be just the way it is.

Not sure of the best way to remediate arsenic, but if it's natural, I'd try to reinject outboard of the dewatering wells.

f-d

You should get a copy of your discharge permit and your water analysis. These documents will tell you the extent of your problem.

Filtration of the runoff will remove the arsenic.
