What should be done regarding soaps, solvents, or detergents used in vehicle washing?

Soaps, solvents, and detergents used in vehicle washing can contain harmful substances such as phosphates, heavy metals, and petroleum products, which can adversely affect water quality and aquatic life. By containing these materials and preventing their discharge into stormwater systems, we can help mitigate pollution and protect water resources. This practice is critical for compliance with environmental regulations aimed at minimizing the negative impacts of industrial and urban runoff on water bodies.

The other choices either misrepresent the safety of discharging these materials into stormwater or promote irresponsible usage. It's essential to manage these substances properly rather than disregarding their potential environmental harm. Implementing containment measures ensures that any pollutants can be treated before entering waterways, thereby contributing to effective stormwater management and ecological conservation.
