Setback Distances Not Sufficient Interestingly, there is no national regulation in place for how close wells can be built to residential structures or schools. This is known as a setback distance and is commonly regulated at the state level. Pennsylvania does not regulate the water quality of private well water.

But what if we told you that most air regulators are fighting air pollution with one hand tied behind their back, unnecessarily? Indirect source rules, known as ISRs, are robust but underutilized regulations that can reduce the indirect air pollution spewed around big facilities like warehouses, logistics centers, or ports.
