You can use your in-house treated lake water to do dishes, laundry and to shower, providing there's no odour or discolouration. But do NOT ingest it in any way, including teeth brushing, ice cubes, etc. See the important notice from Mrs. Agnès Grondin, Biologist and Environmental Advisor at the MRC of Argenteuil which follows.
