Proximity to Water
Section 560
Section 560.203 Proximity to
Water
Livestock waste should not be
applied within 200 feet of surface water unless the water is upgrade or there
is adequate diking. There should be a vegetative strip between the application
area and any surface water. Waste should not be applied within 150 feet of any
water well. Conservative loading rates should be used in the case of a high
water table or shallow earth cover to fractured bedrock. Caution should be
exercised in applying wastes, particularly on porous soils, so as not to cause
nitrate or bacteria contamination of ground waters. Such shallow ground waters
are often the source of private wells in rural areas.
