The Sustainable Groundwater Management Act of 2014 significantly changes groundwater law and management in a variety of ways, but also retains some elements of groundwater law and management that existed prior to SGMA.

In one paragraph each, please describe:

1. One principle or practice that changed; and
2. One principle or practice that stayed the same.

For each, describe the nature of the principle or practice with as much specificity as possible, and give your opinion about the change or non-change.
