Why E. coli Testing Matters

E. coli is a key indicator of fecal contamination in water systems. Its presence can indicate a risk of exposure to harmful pathogens. Whether you’re testing potable water, cooling towers, or conducting post-flood assessments, fast and accurate E. coli testing is critical for:

  • Public health protection

  • Regulatory compliance (EPA, NJDEP, CDC)

  • Environmental inspection reports and client safety assurance
