FACTOR 4: Public Health Impact
Is there a public drinking water supply located within 50 miles downstream of the effluent discharge (this Includes any body of
water to which the receiving water Is a trlbutary)t A public drinking water supply may include InRltredon galleries, or other
methods of conveyance that ultimately get water from the above referenced supply.
ES (If yes, check toxicity potential number below)
❑,NO (if no, go to Factor S)
Determine the human health toxicity potential from AppwWlx A. Use the same SIC code and subcategory reference as In Factor 1. (Be
sure to use the hip health toxicity group column — check one below)
