These chemicals must never be dumped on the ground, in a hole, down a drain, or anywhere except at an authorized hazardous waste collection center. These centers also accept used motor oil and antifreeze. Check your local newspaper for information on a household waste collection day and call auto parts stores for the location of nearby collection centers. A good rule is to keep as much filtering vegetation as possible between animals or animal wastes and any water body. Never locate high-use areas adjacent to creeks, streams, or wet areas.
Pollution is difficult to control from bare, trampled soil.
Pasture units should not contain a creek or other water body. Allowing livestock unlimited access to the creek will break down the streambank and deposit waste directly into the water. Ensure that animal holding areas slope away from nearby water bodies to reduce the risk of water runoff pollution. A berm around paddocks is sometimes useful for rerouting water flows. The general rules above apply to all creeks, ponds, and wet areas.
