This Survey assesses the risk to water quality posed by discharge of milking center wastewater. Please answer all questions for a fair evaluation.

Location and Site Characteristics:

1. Is the milkhouse more than 50 feet from a water well?

Yes
No
Corresponding magnitude of risk

2. Is the wastewater settling tank or septic tank at least 50 feet from a well?

Yes
No
Corresponding magnitude of risk

Answer Question 3 if you use a settling tank prior to discharge, otherwise go on to the next question.

3. Is the wastewater discharge area at least 500 feet from the well ?

Yes
No
Corresponding magnitude of risk
 

Answer Question 4 if you use a septic tank prior to discharge, otherwise go on to the next question.

4. Is the septic absorption field at least 100 feet from the well?  

Yes
No
Corresponding magnitude of risk

In Questions 5 through 9, "discharge area" refers to either a surface infiltration area or a septic absorption field.

5. How far is the discharge area from the nearest:

a) surface water
Less than 100 feet
100 to 200 feet
More than 200 feet
Corresponding magnitude of risk

b) tile inlet
Less than 100 feet
100 to 200 feet
More than 200 feet
Corresponding magnitude of risk

6. Is the discharge area downslope from?

a) well?
Yes
No
Corresponding magnitude of risk

b) surface water?
Yes
No
Corresponding magnitude of risk

c) tile inlet?
Yes
No
Corresponding magnitude of risk

7. What is the texture of the soil in the discharge area?

Clay
Loam
Sand
Corresponding magnitude of risk

8. Describe the soil drainage at the discharge area.

Poor
Good/Moderate
Excessive
Corresponding magnitude of risk

9. How deep is the soil layer above the top of the water table of fractured bedrock?

Less than 3 feet
4 to 10 feet
More than 10 feet
Corresponding magnitude of risk
 

Wastewater Tank Maintenance:

10. Does the wastewater settling tank or septic tank have any leaks?

Yes
No
Corresponding magnitude of risk

11. How many times a year do you clean out your settling tank or septic tank?  

At least 3 times field
Twice
Once or fewer
Corresponding magnitude of risk

Milkhouse Cleanup:

12. What percentage of waste milk is poured down the drain?

Less than 10%
11 to 50%
More than 50%
Corresponding magnitude of risk

13. Do you remove manure and excess feed prior to washdown ?

Yes
No
Corresponding magnitude of risk

14. Is the first pipeline rinse captured and added to the barn manure?

Yes
No
Corresponding magnitude of risk
