Note
Estimated concentrations of chemicals with Koc values greater than 9995 ml g-1are beyond thescope of the regression data used in SCI-GROW development. If there are concerns for such chemicals, a higher tier groundwater exposure assessment should be considered, regardless of the concentration returned by SCI-GROW
