Citation for safe level?
[edit]"Water that is being shock chlorinated should not be swum in or drunk until the sodium hypochlorite count in the water goes down to three ppm or less." is plainly absurd. The safe level for swimming and drinking is quite unlikely to be the same :) — Preceding unsigned comment added by Rob* (talk • contribs) 02:24, 25 June 2017 (UTC)
