  1. Protecting Our Shared Water Resources Based on a national program, adapted and field-tested in Pennsylvania since 1992, the first part of this system focuses on top priority water quality issues around farmsteads. Additional farmstead issues and possibly field-based materials will be developed as resources are available.

  2. Farmsteads are extremely busy places. Livestock buildings and barnyards, chemical storage and mixing, as well as homes and septic systems are concentrated on a few acres.

  3. More than 95 percent of our nation’s rural residents depend on groundwater for their water needs. Surface water streams and ponds also play an important role in the work and recreation of farm families. Groundwater moving underneath and surface water flowing through farms is affected by what happens along the way and carries the results downstream.

  4. Somewhere in the midst of the farmstead there is usually one or more wells supplying the water needs for the livestock and the people. Many of the activities around the well head can potentially contaminate the groundwater.

  5. It was once thought that soil was a perfect filter, magically removing contaminants before they reached our wells. Unfortunately, soil cannot filter out all contaminants. Pollution prevention is the key to maintaining a safe water supply.

  6. Activities around farmsteads can also affect surface water. Pesticides, bacteria, nitrogen, and phosphorus are major pollutants that can move from farmsteads directly into streams.

  7. Is an educational tool • Promotes water quality awareness • Can recognize environmentally courteous farmers The Pennsylvania Farm*A*Syst – Farm Evaluation System – is an educational tool about the relationship of farm conditions and management to water quality. It can promote an awareness of how specific features around a farm affect water quality. It can also be used to recognize farmers who invest the extra effort to protect water quality.

Site Identification #1. The farm evaluation system is a scorecard approach to compare conditions and management on individual farms to the best current standards for water quality protection.

  9. It can be used as a self-evaluation or in cooperation with a technical advisor.

  10. A cooperative effort among: • Penn State Cooperative Extension • Pennsylvania Association of Conservation Districts • Pennsylvania Department of Agriculture • Pennsylvania Department of Environmental Protection • USDA Natural Resources Conservation Service

  11. System Includes: • Introduction • Farmstead Map • PreliminaryScreening Quiz • Worksheets • Wrap-up Activities

  12. Preliminary Screening Quiz: • Short series of questions for each worksheet • Quickly target the most appropriate worksheets for a more detailed evaluation

  13. Farmstead Map: • Sketch of farmstead/farm to locate significant features related to water quality • Source of useful information for completing worksheets or as a record for changes that are made

  14. Farmstead Map The maps do not need to be fancy. They are intended to show relationships around the farmstead. Specific measurements can be added to the sketch from field notes as needed.

  15. The current program focuses on ten priority areas around the farmstead. Additional worksheets are planned for other areas of the farmstead and for field activities.

  16. Worksheets: • 1. Water Well Condition and Construction • 2. Pesticide and Fertilizer Storage and Handling • 3. Household Wastewater Treatment System • 4. Barnyard Conditions and Management • 5. Milkhouse Waste Management • Stream and Drainageway Management • Petroleum Storage and Handling • Silage Storage Management • Animal Waste Storage and Management • Animal Waste Land Application Management

  17. Each worksheet follows the same format so the topics and sequence are the same for each category. • Worksheet Contents: • Why be concerned? • How to rank groundwater and surface water protection using this worksheet • How to complete the worksheet • Ranking matrix • How to use these ranks • Glossary • Acknowledgements

  18. Wrap-up Activities: • Overall Farm Ranking— evaluation of conditions and options for improvement • Post-Evaluation Survey— to be used as part of an educational program

  19. The condition and construction of wells on the farmstead is the focus for worksheet number one. The area immediately surrounding the well is critical to the water quality of the well.

  20. Wells should be located uphill or far away from contamination sources. Surface water should be diverted away from the wellhead.

  21. Septic Tanks 50 feet Septic Leach Fields 100 feet Barnyards 300 feet Separation Distances Well Contamination sources such as septic system drainfields, barnyards, and fuel tanks should be located as far from the wellhead as possible – preferably greater than 300 feet.

  22. Well caps and casings should have no visible cracks or holes. Well caps should always be firmly secured over the well casing.

  23. Casing Height Well casings should be at least 8 – 12 inches above the ground to prevent water from running down the side. 1 foot

  24. Dug wells are much more susceptible to contamination than drilled wells. Abandoned dug wells are like sinkholes, serving as a direct conduit to groundwater. These wells should be adequately sealed to reduce the risk of pollutants directly entering the shallow groundwater.

  25. Well Condition and Construction The condition of every well on the farm can be scored on each of these features. • Type of well • Age of well • Position • Separation distances • Condition of casing and cap • Well sealing • Casing depth • Casing height • Backflow • Abandoned wells

  26. Pesticide and fertilizer storage and handling is the focus of worksheet number two. Dry pesticide formulations are easier to manage safely and are less likely to accidentally contaminate groundwater than liquid materials.

  27. The amount of pesticides and fertilizers should be kept to a minimum. Accidental leakage of pesticides should be avoided and floors in the storage area should be impermeable so that spills can be cleaned up before the pesticides can leach away.

  28. Pesticides should be securely locked away at all times and stored in their original containers with the original labels. They should be kept away from busy areas where they may be bumped or damaged.

  29. Water well 300 feet minimum separation distance Storage & Handling Area Storage & Handling Area Pesticide storage and mixing areas should be at least 300 feet from the wellhead.

  30. Properly constructed pesticide and fertilizer mixing pads can prevent spills and rinse water from getting into streams or groundwater.

  31. A backflow prevention device provides an air gap between the water supply and the sprayer tank that helps to avoid backsiphoning of pesticides directly into the water.

  32. Keeping an eye on a spray tank the whole time it is being filled will reduce the risk of accidents that could contaminate groundwater or nearby streams.

  33. Cleaning by triple rinsing and proper disposal of pesticide containers at a pesticide container recycling site or an approved landfill helps to avoid the small spills and leaks or unintentional contamination.

  34. Rinsing sprayers and applying the rinsate on a field as recommended on the pesticide label keeps the extra pesticide away from critical areas around the farmstead where safe handling may be more difficult.

  35. Pesticide and Fertilizer Storage and Handling Pesticide and fertilizer storage and handling can be ranked on each of these categories. • Location • Geologic materials • Amounts and types • Length of storage • Clean-up • Security of storage • Containers • Mixing areas • Water source • Backflow prevention • Supervision • Container disposal • Clean-up

  36. Household wastewater management is the focus of worksheet number three. Nearly one-third of Pennsylvania homes, mostly in rural areas including farms and rural residences, rely on septic systems. Malfunctioning systems are common and can be a source of groundwater or even surface water contamination.

  37. Pumping septic tanks on a regular basis helps the bacteria in them working effectively and prolongs the useful life of the absorption field. The recommended frequency depends on the size of the tank and the number of people using the system.

  38. Septage can be conveniently handled at a traditional sewage treatment plant. Other options are possible, but they generally require careful management and following detailed guidelines.

  39. Wellhead 100 feet separation distance Septic system drain field Wells should be located at least 100 feet from the septic drain field.

  40. Septic systems that have been in place for more than 15 years should be regularly inspected for leaks.

  41. Household Wastewater Household wastewater management can be ranked on each of these features. • Age of system • Separation distances • Quality and quantity • Treatment system • Septic tank pumping • Disposal of septage

  42. Barnyard management is the focus of worksheet number four. Exercise lots, feedlots, and barnyards are often areas with a high density of livestock. They require effective management to minimize potential pollution.

  43. Keeping clean water clean is an essential feature of successful barnyard management. Rain spouting that collects roof water and channels it away from the barnyard reduces the amount of water that can pick up pollutants from the barnyard.

  44. Upslope diversions that keep runoff from cutting through the barnyard will also reduce the barnyard runoff to be managed.

  45. Treating any contaminated water leaving the barnyard can be done by directing runoff into a manure pit or across a filter strip. A well-designed filter strip with rapidly growing vegetation removes sediment and absorbs nutrients.

  46. Regular cleaning and scraping reduces the amount of manure leaving the barnyard.

  47. Barnyard 100 feet minimum separation distance Water well Barnyards located at least 100 feet from the nearest well are less likely to pollute groundwater.

  48. Grassed exercise areas for cattle not only keep them healthier, but the vegetative cover reduces runoff as compared to a bare earthen exercise area.

  49. BarnyardManagement Barnyard management can be ranked on each of these features. • Separation distances • Clean water management • Runoff control • Scraping practices • Vegetative cover • Animal access • Animal density/size

  50. Milkhouse wastewater management is the focus of worksheet number five. Because milkhouse wastewater usually contains milk solids, fat, manure, and soil, it can overload normal disposal systems and be a source of water pollution.
