Joe Gurrieri

Joe Gurrieri is a hydrologist with the Reclamation Division of the Hard Rock Bureau of the DEQ.It is his responsibility , in that capacity , to review mining plans as they relate to hydrology.In that capacity he was familiar with the facts that pertained to SPJV's pump tests.Based on the data provided by SPJV he concluded that there was no beneficial use of water which would be interfered with by the proposed mixing zones and that neither the biological resources of the Blackfoot River nor recreational use of the river would be affected.He determined that by the end of the mixing zones , all constituents of the pumped water , including arsenic , would be below human health standards and would not present a problem in terms of toxicity.

Gurrieri calculated that the concentration of arsenic at a point 3000 feet down gradient from the Landers Fork infiltration gallery would be .008 mg/l and that the arsenic concentration 5000 feet down gradient from the Blackfoot infiltration gallery would be .009 mg/l.These concentrations are lower than the standards for groundwater or surface water but greater than the concentrations in the receiving water.
