(adapted from

U.S. EPA 1994)

a Values expressed as mg/L, except for pH, which is unitless and total and fecal coliforms which are no./100 mL b The data presented in this table were complied from many sour

ces. The inconsistency of individual date sets results in some sk

ewing of the data

and discrepancies when individual parameters are compar

ed. This is taken into account in offering suggested design value
