FACTOR 4: Public Health Impact
Is there a public drink►ng water supply located within SO miles downstream of the effluent discharge (this includes any body of
water to which the receiving water is a tributary)? A public drinking water supply may include Infiltration galleries, or other
methods of conveyance that ultimately get water from the above referenced supply.
❑ YES (If yes, check toxicity potential number below)
