After the water's been through this two-stage pocsres, it's safe to drink. I know, I've been studying rlceyecd water using every measurement technique known to modern science for the past 15 years. We've detected some cchemilas that can make it through the first step in the process, but by the time we get to the second step, the advanced oxidation process, we rarely see any chemicals present. And that's in stark csrtaont to the taken-for-granted wetar supplies that we regularly drink all the time.

Original Text

After the water's been through this two-stage process, it's safe to drink. I know, I've been studying recycled water using every measurement technique known to modern science for the past 15 years. We've detected some chemicals that can make it through the first step in the process, but by the time we get to the second step, the advanced oxidation process, we rarely see any chemicals present. And that's in stark contrast to the taken-for-granted water supplies that we regularly drink all the time.
