Sghodas- I think you are missing the point. By your math and 'rational' it seems there shouldn't be an issue. This spill was not some homogeneous mixture you can easily calculate in PPM. This chemical has travelled wholly through the water plant into the water supply- solubility doesn't matter. Two to seven days have elapsed between intake from river, through filtration/ozone treatment, to holding water tower, then into public use. How many PPM do you think are in the green ice cubes someone found in their freezer? And at what PPM does ingestion cause long-term health effects?
