Proper use and handling of agricultural chemicals, such as back-siphoning prevention , can greatly reduce the chances of water contamination. Although agricultural chemicals and fertilizers are potential sources of groundwater contamination, proper management can minimize the risk of contamination. Proper timing and application of agricultural chemicals greatly reduces the chance of groundwater contamination. Proper farmstead design and layout can significantly reduce the chance of well contamination. Surface runoff should not be allowed to pond near the surface of wells.
Animal waste is one of the greatest contributors to water quality problems in Indiana.
Proper management and application of animal wastes can minimize potential problems. For additional information concerning agricultural practices to reduce the risk of water contamination, contact the Cooperative Extension Service at Purdue University.
