Dave,

My company specializes in constructed wetland bioremediation systems that have proven to be highly effective at removing the metals your are interested in.  The systems use no or very limited chemical reagents (non-toxic coagulants are sometimes required to facilitate gravity settling of ultrafine Fe/Al hydroxides, but this is not required on most sites) and operate on gravity flow with minimal maintenance and oversight.  Our "latest and greatest" system is located in Southwest Colorado and has been written about in local media there:

Typical removal rates for As, Cu, ​Fe, Mn, Al, and Zn at that system are 90-99% and meet Colorado's stringent water quality standards for public drinking water supplies and cold water fisheries.  Take a read through those articles and if your are interested in hearing more you can email me at dan@rmc-ut.com or call at 801-255-2626.

I am definitely interested in hearing more about the water source you are hoping to treat.
