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.
Pharma Pushes Back on State PFAS Regulations
Drugmakers claim that broad state PFAS laws are overly burdensome. But environmental health experts aren’t convinced.
