a   Soil Saturation Limits calculated using an foc of 0.006 g/g and a system temperature of 25°C.

 

b   Soil Saturation Limits calculated using an foc of 0.002 g/g and a system temperature of 25°C.

 

c    Csat for pH of 6.8.  If soil pH is other than 6.8, a site-specific Csat should be calculated using equations S19 and S29 and the pH-specific Koc values in Appendix C, Table I.
