Every state suffers from early industrialization and lingering pollution, not just CO2.
Maine, my favorite place has naturally occurring arsenic in the well water as does north Jersey. EPA raises the level of acceptable arsenic levels in water that people have been living and thiving on for centuries. Sometimes the technology is so sensitive, measurements can be taken to a finer level than ever before. So in a way the EPA creates new pollution with finer detection capability.
VT for instance, nice place, fresh air..has pretty much the same fish consumption advisory as NJ. In their moose hunting guide they caution against eating organ meats due to the accumulation of cadmium.

More concerned about the NJ EPA. Give them a chance and NJ will be off bounds to people. The EPA is good for the state and country but the current crop of bureaucrats have become overzealous and need to be reined in. CO2 a pollutant? only in a bureaucrats dreams of federal grants to earn a career and degree by supporting the fantasy of human caused global warming.
