How should used foam solution or wash water be disposed of?

• A. Discharged to stormwater after filtration.
• B. Poured into the sanitary sewer.
• C. Stored on site for reuse without treatment.
• D. Collected and disposed through approved wastewater treatment or hazardous waste channels; do not discharge to stormwater.

Answer: (D)

Used foam solution and wash water contain contaminants such as PFAS that can harm the environment, so they must be treated and disposed of through approved channels rather than released untreated. Discharging to stormwater is not allowed because storm drains lead directly to surface waters without treatment. Pouring into the sanitary sewer is not universally permitted and may be restricted, since facilities may not remove these contaminants effectively or could violate local rules. Storing on site for reuse without proper treatment risks spreading contamination. The juiste approach is to collect the used foam solution and wash water and dispose of it through approved wastewater treatment or hazardous waste channels, following regulations and the facility’s procedures.
