MCL vs. Guidance
Maximum Contaminant Levels (MCLs) are legally enforceable standards. Failure to comply can lead to fines, required remediation, and public health notices.
Action Levels / Guidance are non-enforceable health benchmarks that often trigger public notification or further investigation but do not (yet) mandate treatment by law.
Retail & Logistics Risk
For facilities like Distribution Centers and Retail Stores, the primary risk is "Facility-Owned Systems." If your warehouse uses a private well to provide water for >25 employees, you are likely classified as a Non-Transient Non-Community water system, making you directly responsible for testing and filtration.
