Crossbow Herbicide does contain an active ingredient that has soil residual. Per the product label: "This chemical has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination."
If you are applying the product as directed to apply to fresh cut stumps, then there should not be a risk of contamination in most circumstances. However, this product is not labeled for use around aquatic areas or where there is risk of flooding.
