Accurate Testing for the
Most Hazardous Water Damage

Category 3 water damage, also known as black water contamination, involves water that is grossly unsanitary and poses significant health risks. Our certified professionals provide independent Category 3 water testing services across New Jersey, helping property owners, insurance adjusters, and contractors assess contamination and determine the appropriate course of action.

We do not perform water cleanup or restoration. Our focus is on unbiased, third-party testing and analysis you can trust.

What Is Category 3 Water?

Category 3 water includes severely contaminated water that may contain:

  • Sewage or toilet backflows

  • Floodwater from rivers, oceans, or streams

  • Standing water with bacterial growth

  • Water carrying hazardous chemicals, debris, or pathogens

This type of water can infiltrate structural materials, HVAC systems, and air spaces, potentially creating dangerous conditions long after the water itself is gone.

Why Testing Matters

Not all water damage is immediately visible — and not all damage is equally dangerous. Category 3 water can leave behind:

  • Harmful bacteria (e.g., E. coli, Salmonella)

  • Viruses (e.g., Norovirus, Hepatitis A)

  • Mold and fungal spores

  • Chemical contaminants

Proper testing is essential to confirm contamination levels, determine exposure risks, and guide safe cleanup or demolition efforts. Testing is often required for insurance claims, property transactions, and post-flood certifications.

When to Schedule Category 3 Water Testing

You may need testing if:

  • Your property experienced a sewage backup, overflow, or toilet discharge

  • There was flooding from an external source (river, storm, sea)

  • Standing water remained on the property for more than 24 hours

  • You're assessing post-flood safety or insurance documentation

  • A remediation contractor requests third-party verification
