Licensed Oversight For Public Water Systems

Franklin County Lab provides operator services for public water systems serving 15 or more connections or 25 or more individuals daily. As Missouri DNR enforcement has become more active, system owners are expected to maintain licensed oversight and keep reporting current.


We help keep operator responsibilities organized and documented. That includes inspections, required sampling, and official correspondence so your system records stay in order and your reporting stays on track.

Monthly BacT Sampling And DNR Reporting

We complete the required Monthly BacT sample draws and ensure results are processed and reported in line with Missouri requirements. Along with sampling, we inspect systems, review operational integrity, and manage documentation supporting DNR reporting.



If your system has received a notice or is at risk of falling out of compliance, we can help you identify what needs to be corrected and what should be submitted next. The focus is on practical follow-through so your system can return to good standing and maintain consistent service for the people you serve.

Advanced Licensing And Field Expertise

Our operator team includes advanced Missouri credentials, including Drinking Water Treatment B, along with leadership that understands water systems and field work. That background supports stronger decision-making when system mechanics, chlorination processes, or infrastructure concerns affect sampling outcomes and compliance steps.



We also work with lab standards and reporting expectations, which helps connect what the system is doing with what the documentation needs to show.

A Compliance Partner, Not Just A Contractor

Public water supply owners are legally responsible and expected to maintain clear records. We support that work through a structured service that includes inspections, special sample draws when required, and ongoing documentation help.



The goal is to make regulatory tasks easier to manage over time by establishing a repeatable process and clear next steps when something changes.
