Strong winds will push water to the east end of Lake Erie, causing up to a 6 foot rise in water levels.
There could be some pockets of flooding near Buffalo.

Good news: World’s largest chemicals group, BASF, will phase out #PFAS by '28. US-based Ecolab will exit PFAS by '26 -nervous investors & financial risk after 3M fiasco. Chemours & Solvay closed plants this year in France, but not in U.S. (Chemours trying to expand in NC)

World's biggest chemicals group to exit PFAS 'forever chemicals'
BASF will phase out PFAS by 2028. This decision signals a new trend among chemical giants to phase out “forever chemicals".

Whoa. Looks like greater than 4 ft water level rise at the east end of Lake Erie at Buffalo today. Winds are blowing east-northeast parallel to the long axis of the lake. See news stories in replies.

Rochester is receiving $14 million to replace lead pipes and help ensure its drinking water is safe and clean. But New York can do more and we urge state leaders to get all the lead out of our water.

Boohoo- such a 'burden' of reporting the presence of #PFAS so consumers & agencies identify sources of harmful chemicals & reduce exposures. What about the body burden?!! "Pushback may not only be about compliance issues but also about strategically avoiding PFAS regulations" - boom.
Pharmaceutical companies lobby against state PFAS regulations claiming compliance chaos. Environmental advocates say most state laws align, the real issue is companies don't want transparency about forever chemicals in medications.

Drugmakers claim that broad state PFAS laws are overly burdensome. But environmental health experts aren’t convinced.
