Communities can protect water resources by instituting minimum requirements for organic matter in soil. Compost, much of which is generated locally, when incorporated into soil improves water holding capacity and soil quality. By incorporating compost into soil for establishment of lawns and landscape plantings, water used for irrigation is conserved and the potential for groundwater contamination is reduced.
