Your water category can tell you a lot about your health risks.

Category 1 water originates from a sanitary water source and does not pose substantial risk from dermal, ingestion, or inhalation exposure. Simply let Envirogyn review the water sources, like a broken supply line, and we can make a category determination in just 30 minutes. Categories that are not type 1 can indicate whether your health at home is at risks of infection - a serious problem from other categories of water - or require a review by medical personnel, which means you may consider probiotics, vitamin prevention, and more.

Category 1 water can deteriorate to Category 2 or 3.

Category 1 water that flows into an uncontaminated building does not constitute an immediate change in the category. However, Category 1 water that flows into a contaminated building can constitute an immediate change in the category.

Microorganism Growth Curve

Once microorganisms become wet from the water intrusion, depending upon the length of time that they remain wet and the temperature, they can begin to grow in numbers and can change the category of the water. Odors can indicate that Category 1 water has deteriorated.

Category 2 contains the beginning of pains.

Each area of Category 2 water contains a potential for sickness and discomfort. With Category 2 water, Envirogyn can navigate and record potentially unsafe levels of microorganisms or nutrients for microorganisms, as well as other organic or inorganic matter (chemical or biological). If consumed by humans, this classification, and any notes provide can be provided to your Health professional. You can share the information with your doctor and have a better-informed conversation about your health.

We have your health in mind.

Unusually high or low health risks and ingestion of Category 2 water could be signs of a serious condition. Examples of Category 2 water can include discharge from dishwashers or washing machines and overflows from toilet bowls.

But many people don’t recognize the risks, so the underlying health causes go undiagnosed. Once microorganisms become wet from the water intrusion, depending upon the length of time that they remain wet and the temperature, they can begin to grow in numbers and can change the category of the water and cause Category 2 water can deteriorate to Category 3. Envirogyn regularly checks the water penetrance and alerts you to these irregularities — so you can take action and consult your doctor.

Category 3: Grossly contaminated water all in one place.

All your water cleanup needs, as well as information from your health and prevention, is provided by Envirogyn during a Category 3 Water cleanup. Pathogenic, Toxigenic, and other harmful agents can cause significant adverse reactions to humans if contacted or consumed.

Examples of Category 3 water can include, but are not limited to: sewage, wind-driven rain from hurricanes, tropical storms, or other weather-related events if they carry trace levels of contaminants (e.g., pesticides, or organic substances).

Regulated Hazardous Materials

If a regulated or hazardous material is part of a water damage restoration project, then a Envirogyn will acquire any specialized experts to assist in damage assessment for you. Envirogyn does comply with applicable federal, state, provincial, and local laws and regulations. Identification of regulated materials posing potential or recognized health risks can include, but are not limited to: arsenic, mercury, lead, asbestos, polychlorinated biphenyls (PCBs), bulk or regulated use pesticides, fuels, solvents, caustic chemicals, and radiological residues. Our Board Certified Scientists make a priority out of identification.


For situations involving visible or suspected mold, Envirogyn maintains a Board Certified Mycologist on staff and utilizes the IICRC Standard and Reference Guide for Professional Mold Remediation. The presence of any of these substances does not constitute a change in category; but our qualified persons can abate regulated materials and can remediate mold prior to drying.

1. Determinations of projects are objective and vary.
2. Water intrusion classes based on evaporation and penetration materials are standard under IICRC S500. This means that materials may be subjective for different areas like granite counter tops or formica countertops. However, wet materials should not be taken as definitive without removal activities.
3. Class 3 water generally requires a natural disaster or major plumbing or sewage rupture.
