Indiana Farmstead Assessment for Drinking Water Protection

Livestock Waste Storage

Use this survey to assess the risk to water quality posed by your livestock waste storage. Circle the answer that best describes your situation. At the end of each section sum the numbers that correspond to each answer for the section. When you have completed the survey sum the section totals for the risk assessment score. Refer to Fact Sheet 7 for more information on livestock waste storage.

For each question, a (1) represents a higher risk to drinking water than a (3).

What is the soil texture at the site of your manure storage structure? clay (3) loam (2) sand (1) 4. Is the water table or fractured bedrock layer more than 20 feet below the bottom of the manure storage structure? Yes (3) No (2) 5. Is the seasonal high water table ever within 3 feet of the bottom of the manure storage structure? Yes (2) No (3) Location section total __________
