In most industrial waste products that contain the toxic chemical XTX, the concentration of this chemical is approximately 1,000 parts per million. A federal law intended to reduce the harm that can result from the introduction of XTX into the environment permits a company to dispose of these waste products in a dump for hazardous waste, but only if the concentration of XTX is below 500 parts per million. Waste products with concentrations above that level must be destroyed by incineration. The law further specifies that manufacturers may not dilute XTX-containing waste products to bring their concentration of XTX down to a permissible level for dumping.

Which one of the following, if true, argues most strongly for the inclusion of the antidilution provision of the law?
