More recent recommendation from DOH is to NOT drink catchment, regardless of treatment methods. Too many hazardous substances being spewed by the volcano.

"In areas affected by volcanic emissions, catchment systems collect very acidic water that can leach harmful contaminants such as lead from roofing and plumbing materials. Volcanic ash can also get into the water, cause contamination, and interfere with common water treatment methods such as filtration and chlorination.
Even when there is no volcanic activity, extra care should be taken when using water from rainwater catchment systems. For health and safety reasons, homeowners should NOT use catchment water for drinking or preparing food. County water spigots should be used instead as a safer water supply."
