This animal waste management self-assessment is an important part of the Farm-A-Syst program. This voluntary program helps you evaluate activities and conditions on your farm that could be a threat to your drinking water and to water quality in nearby lakes or streams. This introductory information will help you understand the importance of managing animal wastes, from water quality, health, and environmental perspectives. Read it carefully before completing this self-assessment.
This self-assessment is one in a series of voluntary environmental self-assessments in the Farm-A-Syst program. For a complete picture of all activities or conditions on your farm that could affect water quality, review and complete the other Farm-A-Syst environmental self-assessments available from the Extension Energy Center. You also are encouraged to review and complete other self-assessments in the companion Home-A-Syst program, available at your county Extension office.
Your responses to this self-assessment are for your use. Although completing this self-assessment is voluntary, taking a few minutes to respond to it may help you identify potential areas on your farm that could lead to water quality problems. You may find it useful to involve your spouse and/or children in completing your self-assessment. If you need other help or follow-up information, contact your county Extension office.
Why You Should Be Concerned About Animal Wastes
If not managed properly, animal wastes from concentrated hog, beef, dairy, and poultry operations can affect your health, water quality, and the water quality and health of others. Bacteria in animal wastes can contaminate drinking water and may cause potentially serious illnesses. High levels of nitrates, a form of nitrogen that develops naturally in animal wastes, in drinking water may particularly harm unborn or young infants and young livestock. Nutrients in animal wastes that enter streams also may lower oxygen levels and kill fish and other wildlife. Odors from animal operations may cause problems with neighbors and create a negative public perception of agriculture.
Proper animal waste management reduces these concerns. Animal wastes also are an important source of plant nutrients for crop production. Other aspects of animal production, such as how animal carcasses are disposed of and silage storage methods, also may contaminate water by introducing bacteria or nitrates. For these reasons, silage storage and animal carcass disposal are included in this self-assessment.
To protect water quality, your animal waste management system should be properly designed, built, and maintained. At a minimum, your animal waste lagoon, animal waste storage area, or animal waste land application area should be at least 100 feet from a private well or other water source, and preferably farther away if possible. You should also apply animal wastes to growing crops or pastures when possible and according to approved application rates. Animal waste land applications also should be 1,000 feet or farther from other residences. Cover any animal wastes transported on public roads to avoid possible pollution.
A Word About Regulations
For your information, some activities in this self-assessment are listed in bold type to indicate they could violate state water quality, health, or environmental laws. These regulations concern the potential of animal wastes to contaminate your own water supply, the water supply of others, or any designated state waters such as a lake, stream, and other water sources.
Always keep in mind that although regulatory considerations are important, they should not be the only factor in your animal waste management decisions. Many unregulated activities on your farm can affect water quality. Consider required distances between animal wastes and a water source as minimum safe distances and try to maintain farther distances if possible.
If you need more information about these regulations, contact the Mississippi Department of Environmental Quality, Mississippi State Department of Health, your county health department, or the Mississippi Board of Animal Health. For information on designing, building, and maintaining an animal waste management system, contact your county Soil Conservation Service office or county Extension office. See the bottom of this publication for information on how to contact these agencies.
Understanding Your Self-Assessment
Your drinking water and other water supplies are least likely to be contaminated by animal wastes if you use as many of the low-risk practices listed in this self-assessment as you can reasonably follow. You may not be able to use all low-risk practices, but use as many as practical to protect your water quality, health, and the water quality and health of others.
As you complete your self-assessment, do not be alarmed if you check several or even many high-risk statements. This does not automatically mean your farm has water quality problems. It could, however, tell you that your attention may be needed to avoid potential problems. A score sheet is included to help you better understand your completed self-assessment. If you need additional help, contact your Extension office.
Directions
This self-assessment is a series of three-part statements, each with a low, medium, and high ranking. This ranking relates to the level of risk to your drinking water quality or other environmental risks associated with that activity or condition. First, read all statements in each set; then check the ranking that best describes conditions on your farm. Some parts of this self-assessment may not apply to you; read all parts and respond to those that do. Remember, this self-assessment is for your information, and your goal is to apply as many low-risk practices as you can.

Bold type means, in addition to being a high-risk practice, this activity violates Mississippi water quality or health laws.
This score sheet helps you understand your self-assessment by letting you compare your low, medium, and high risk activities and conditions. To do your score sheet, use a pocket calculator and follow these steps:
- First, count your answers for each level of risk in your self-assessment. Write these numbers in the three spaces in the left part of the chart below.
- Second, add these numbers to give your total number of answers. Write this number in each of the three spaces to the right of the divided sign in the chart. You'll use this same number each time to figure a percentage.
- Third, divide your number of answers in each level of risk by your total number of answers. Multiply your answer each time by 100 to convert this number to a percent.
