12. Did you perform any treatment on the water used for drinking or cooking?
This question also helps reveal the sanitary conditions of the household. The most common treatments to drinking and cooking water are: boiling it, using neutralizing pills, or having a filter. The most "artisanal" treatments (ex: having animals that eat insects in the tank), shouldn't be considered.
