State law requires that each individual well be encased in multiple layers of protective, industrial-grade steel casing, which is surrounded by cement to ensure groundwater remains safe during fracking. (Rule 317, COGCC).
Here are a few other regulations that keep Colorado’s groundwater safe:
- Companies must conduct mandatory integrity tests and keep detailed logs to provide evidence that steel and cement well casings are working properly. (Rules 317 and 326, COGCC)
- Colorado is the only state that requires groundwater sampling before and after drilling operations, holding producers accountable. (Rules 608, 609 and 318A.e.(4), COGCC)
