Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about a time you worked with a state drinking water program on a permit or compliance issue. How did that go?

What they are checking: Whether they can build working relationships with regulators instead of treating them as opponents.

Tell me about a time you caught a compliance gap before it became a violation.

What they are checking: Whether they review records closely enough to spot problems early, which is the core value of this role.

This role is remote. How do you stay organized and responsive when your customers, labs and agencies are all in different places?

What they are checking: Whether they can work independently and keep many parties coordinated without someone checking on them.

What would you do

A lab result comes back over the MCL for one of your assigned systems. What happens next, step by step?

What they are checking: Whether they know the confirmation sampling, notification and public notice steps and treat public health as urgent.

How would you explain the Lead and Copper Rule changes to a customer who runs a small system and isn't a regulatory expert?

What they are checking: Whether they can make complex rules clear to customers without talking down to them or oversimplifying.

A lab misses a sampling holding time and the deadline to report is tomorrow. What do you do?

What they are checking: Whether they stay honest with regulators and act quickly to fix the gap instead of hiding it.

An internal team wants to change a treatment process at a customer site. What regulatory questions do you raise before they start?

What they are checking: Whether they know treatment changes often need state approval and can flag that before work begins.

About the work

Walk me through the main monitoring and reporting requirements a public water system has under the Safe Drinking Water Act.

What they are checking: Whether they know the SDWA rules well enough to keep a system compliant without having to look up the basics.

You're managing systems across several states with different rules. How do you keep track of who needs what, and when?

What they are checking: Whether they have a reliable system for deadlines across jurisdictions, since one missed report can mean a violation.

What's your experience with Consumer Confidence Reports? What makes one good?

What they are checking: Whether they understand that the report is both a legal requirement and a public communication tool.
