There are many reasons to test your water. Columbia Labs empowers companies to effectively monitor the environment with results they can trust.

1. Screening for contaminants:

Test water sources before using in your production system.

  • Organics
  • Microbiology- E. Coli, Listeria, Salmonella
  • Nutrients
  • Suspended and Dissolved Solids

2. NPDES Permit Compliance:

  • Wastewater
    • Use water in your process.
    • Must be treated before used again or returned to source.
  • Stormwater

3. Drinking Water (not permitted, but a good idea)
