This article cites a study, which suggests that the movement of liquor constituents from animal-waste lagoons has the potential to degrade ground water quality. The depth of movement and concentrations of lagoon-liquor constituents in the soil underlying three cattle-waste retention lagoons and one swine-waste lagoon were determined. This study investigated the soil beneath four animal-waste lagoons located in Kansas. Results from soil samples collected from under three cattle-feedlot runoff retention lagoons and one swine-waste lagoon indicate the downward movement of lagoon-liquor constituents. Lagoons used to hold animal wastes are commonly constructed of differing sizes and are commonly managed under differing strategies. Given these two variables, lagoon liquor constituent concentrations may be vastly different between and within the same species type. Thus, caution should be used when soil-sampling results from one lagoon are extrapolated to other lagoons without past knowledge of lagoon design and construction, species type, lagoon liquor concentrations, and lagoon and animal management strategies. |
