Acronyms and Footnotes to Table 6
* Indicates dissolved metal criterion; others are total recoverable metals. Each listed dissolved criterion in Table 6 is equal to the corresponding total recoverable criterion before rounding (from the EPA National Ambient Water Quality Criteria Documents) multiplied by the conversion factor (from the Conversion Factors Table); a criterion that is expressed as a hardness (H)-based equation is shown in Table 6 as the conversion factor (listed) multiplied by the hardness criterion equation; an example criterion at hardness=100mg/L is included.
CAS-Chemical Abstract Service number
CRL-Cancer risk level at 1 x 10-6
H-Threshold effect human health criterion; incorporates additional uncertainty factor for some Group C carcinogens.
ln [H]-Natural Logarithm of the Hardness of stream as mg/l CaCO3
ug/L-Micrograms per liter
N/A-Criterion not developed
PP NO-Priority Pollutant Number
