I am seeing some news about the water contamination in the portal https://www.fs.usda.gov/detail/inyo/news-events/?cid=FSEPRD555445.

Does this mean the water availability along the trail is contaminated as well? if so., is the filter and water purification tablets enough to purify and that water can be used. I am wondering whether we will end up in carrying water for the entire 22 miles.

Input on this is appreciated.

Thanks
