Don't have the citations handy, but for this and many other chemicals
the runoff rates vary by orders of magnitude depending on soil type. I
reviewed the available literature pretty thoroughly in the early
eighties and that was clear then. Surely there is more research now.
There may also be effects from the "inert" ingredients on soil macro and
microorganisms (like the nitrogen fixing bacteria in clover and other
legumes). Also this study applies to surface water (usually streams,
rivers etc), and many chemicals adsorb to soil particles, especially the
very fine clays. If they reach bodies of water they are mostly in/on
sediments.
More basic research please....the perpetual plea....
