Utility Lab

The primary mission of the Marion Utilities lab is to monitor the final effluent of the plant and report the results of our analysis in order that we can maintain compliance with our NPDES permit.  We also analyze samples from other stages and processes of treatment to determine how the plant is operating and to maintain optimum efficiency.

We analyze industrial effluent samples collected through our pre-treatment program to monitor and ensure compliance with our sewer ordinance statue.

The Marion Utilities Lab is certified by the Indiana State Department of Health for the bacteriological examination of public waters for the detection of Total coliforms and Escherichia coli in drinking water using the Colilert & Colisure methods. 

Our lab is also certified to perform compliance testing on public swimming pools.

We are also certified to perform heterotrophic plate count and coliform presence/absence using Colilert & Colisure on public swimming pools, as outlined in the 18th edition of Standard Methods for the Examination of Water and Wastewater.

As the only state-approved water laboratory in Grant County, we offer a local laboratory choice for all public water systems that are required to perform weekly, monthly or quarterly drinking water bacteria tests.  Boil order and system check testing is also available.

As a service to the public, we also offer private well water testing for the presence of total coliform and E.coli bacteria.  

The Marion Utilities Laboratory accepts samples for testing Monday through Thursday from 7:00 AM to 3:00 PM.    We are located at 1540 N. Washington Street in Marion, in the Marion Utilities Administration building.

Please stop in or call our Lab at 765-664-2391, ext 120, Monday through Friday from 7:00 AM to 3:00 PM for more information.
