FACTOR 4: Public Health Impact
Is there a public ddnking water supply located within SO miles downstream of the effluent discharge (this Includes any body of
water to which the receiving water Is a tdbutary)? A public drinking water supply may include InRltradon galleries, or other
methods of conveyance that ultimately get water from the above referenced supply.
❑ YES (if yes, check toxicity potential number below)
❑ NO (If no, go to Factor 5)
Determine the human heakh toxicity potential from Appendix A. Use the same SIC code and subcategory reference as In Factor 1. (Be
sure to use the human health toxicity group column — check one below)
