It seems like you're trying to categorize or organize terms related to water regulation and quality. Here's how you could classify them based on their relevant acts and areas of concern:
Clean Water Act (CWA)
- Surface water quality
- Wastewater management
Safe Drinking Water Act (SDWA)
- Groundwater contamination

If you meant to do something different with these terms, let me know!
