|
Aquifer Susceptibility Map
- Represents the natural susceptibility of near surface geological materials.
- Includes Conduits representing wells that may increases the natural susceptibility of the aquifer if poorly constructed
- Ratings are scaled (1-10)
|
|
Hazard Threat of Pathogens
- Based on Land Use Type - includes septic sources and farmland
- Ratings are scaled (1-10)
|
|
Vulnerability Map
- Includes both Susceptibility and Hazard Potential
- Ratings are scaled (1-10)
|
|
Total Loss Map
- Considers cost to the public health care system if people get sick from gastrointestinal illness
- Ratings are scaled (1-10)
|
|
Final Risk Map
- A product of Vulnerability and Loss
- Ratings are scaled (1-10)
