Cincinnati Water Works uses granular activated carbon filtration already, and plans to shut the Ohio River water intakes during the period of maximum contamination (anticipated some time next week). Given that water demand is below peak in the winter (nobody watering yards or washing cars etc), the water in towers and reservoirs will likely be enough to last through the worst part of the plume. I believe they have 3 days of water during peak times, so likely more like 5. Source: chatting with a waterworks engineer after a tour of antique steam engine water pumps.
