MEDIUM SUSCEPTIBILITY - Alluvium over Fall River Formation Susceptibility rating ranges between 14 to 27; range increases to 20 to 35 when fault is present. Unit is more susceptible if saturated
HIGH SUSCEPTIBILITY - Saturated Alluvium over Inyan Kara GroupSaturation increases susceptibility rating from of 20 to 34 for Lakota Formation and 14 to 27 for Fall River Formation to 26 to 42 and 20 to 35 respectively; highest saturation when overlying a fault
LOW SUSCEPTIBILITY - Gravels over Fall River FormationSusceptibility ratings range between 1 to 12; unit is more susceptible when saturated

Susceptibility Units
MEDIUM SUSCEPTIBILITY - Gravels over Lakota FormationSusceptibility ratings range between 7 to 19; unit is more susceptible when saturated
VERY HIGH SUSCEPTIBILITY - Highly Saturated Gravels over Lakota FormationWhen highly saturated, gravels overlying the Lakota Formation become extremely susceptible for accepting and transmitting potential contaminants
