1. Home*A*Syst Site Assessment

2.  Started in 1993  Funded through tonnage fees applied to pesticides and fertilizers sold in Michigan.  Program objective is to educate the public on the importance of groundwater protection  Teach individuals what they can do at their own homes to reduce the risk of groundwater contamination

3. Site Assessment Why Is It Important?

4. Water, Water Everywhere, But NOT All Drops To Drink!

5. Watershed Land area that contributes water to a specific surface water body, such as a pond, lake, wetland, river or bay

6. What Affects Water Quality?  Risks to groundwater and surface water  Soil type  Soil depth  Bedrock depth  Water table depth

7. Groundwater

8. Soil, Bedrock and Water Table  Permeability (penetrable)  Soil Type (based on particle size)  Soil Depth  Bedrock  Water Table (boundary between saturated and unsaturated soil)

9. Home Site Assessment 1. Low Risk /Recommended 2. Medium Risk/ Potential Hazard 3. High Risk/ Unsafe Situation Your Risk Runoff risks to lakes, rivers, wetlands, or other surface water due to soil type Sand/gravel (large particles) Silt/loam (midsize particles) Clay (very tiny particles) Risk to groundwater due to soil type Clay (very tiny particles) Silt/loam (midsize particles) Sand/gravel (large particles) Soil depth Deep (over 12 feet)Moderate depth (3 to 12 feet) Shallow (less than 3 feet) Bedrock Solid, not permeable or fractured Solid limestone or sandstone, or fractured granite or shale Fractured limestone or sandstone Depth to water table Over 20 feet10 to 20 feetLess than 10 feet Nearness to surface water Over 100 feet25 to 100 feetLess than 25 feet
