Yes, I think it's really important for the committee to understand that the biggest misconception around safe drinking water is that you can define it by tables of numbers. This may seem counterintuitive. Safe drinking water ought to mean measuring all these things to give you safety. It's true that, if you could meet all those numbers and monitor all those things continuously, you could probably have safe water, but the fact is you can't. You can't measure in real time most of the things that matter. You can't get your results until long after people have drunk the water, so it's not a preventive approach. The focus has to be on the competence of the operations using processes that we know work for the things that make people sick. That's what keeps water safe.
What works in one place isn't necessarily going to work in another. It's not as simple as just promulgating a table of numbers, and if you exceed these numbers we'll send you to jail. That misconception blinds most people to what needs to be done.
