After floodwater enters a home, do not assume it is safe to clean just because it looks clear or the water has receded. The water source matters: Washington State Department of Health (DOH) guidance classifies floodwater from rivers or lakes as “black water,” which may contain human or animal waste. The EPA also warns that floodwater can contain bacteria, chemicals, or other hazards. If you are uncertain what the water touched, describe that uncertainty before cleanup begins.
Flood exposure is not the same at every address. Cowlitz County’s Comprehensive Flood Hazard Management Plan evaluates flood risk and vulnerability and identifies community mitigation actions. It is countywide planning context, not a statement that every property has the same risk.
Make safety the first decision
Follow local emergency alerts and instructions before returning to a flooded property. DOH advises never turning electrical power on or off while standing in water, and says electrical systems should be inspected by a qualified electrician before power is restored. If you smell gas, leave the area and notify emergency authorities. If you use a fuel-powered generator after a power outage, EPA says it must be outside and at least 20 feet from buildings—never inside a home or garage.
Keep children and pets out of areas affected by contaminated floodwater. Flood cleanup can involve hazards that are not obvious from a quick look; EPA recommends experienced, qualified help when cleanup is difficult or dangerous. If there is immediate danger, call 911.
Why the water source changes cleanup
DOH distinguishes clear water such as tap or rainwater, gray water from sinks, showers, tubs, or washers, and black water contaminated with human or animal waste. Its guidance treats floodwater from rivers or lakes as black water. The label is about the source and possible contamination—not just the water’s appearance.
EPA’s flood-cleanup guidance is written for flood events. It notes that water damage from a pipe leak or rainwater intrusion typically involves fewer hazards and a smaller affected area than hurricane or flood damage. That is why it is useful to explain whether water came from outside flooding, a plumbing leak, or another source rather than assuming all water losses call for the same cleanup.
Do not mix cleaning products. Both EPA and DOH warn against mixing bleach with other chemicals or cleaners. If you are unsure how to handle affected materials or whether it is safe to enter, pause and follow official safety guidance rather than disturbing the area.
What to share when you ask about mitigation
Once it is safe, note which rooms were affected and what you know about the water source. Tell the person you contact if water may have come from a river, lake, sewage, a plumbing fixture, or rain entering the building. Mention whether the water is still present and whether building materials or belongings were touched. You do not need to determine the exact contamination level or diagnose mold on your own.

Once the property is safe to approach, Pacific Restoration can discuss water mitigation and drying options.
Frequently asked questions
Is floodwater from a river or lake safe to clean up?
Do not assume it is safe. Washington DOH classifies river- or lake-origin floodwater as black water because it may be contaminated with human or animal waste. Follow official cleanup guidance and keep people and pets out of affected areas until cleanup is complete.
Does every property in Cowlitz County have the same flood risk?
No. The county’s flood plan evaluates risk and vulnerability and identifies mitigation actions, but that does not mean every address has the same exposure. Use county information for local context and follow current emergency notices for immediate conditions.
Can I switch the power back on after a flood?
Do not stand in water to operate electrical equipment. DOH says electrical systems should be inspected by a qualified electrician before power is restored. If there is an immediate electrical or structural danger, stay away and call emergency services.
Is cleanup after a burst pipe the same as cleanup after river flooding?
Not necessarily. EPA notes that pipe leaks or rainwater intrusion typically involve fewer hazards and a smaller affected area than major flood events. Tell the mitigation professional where the water came from so the next steps can reflect the actual conditions.
What should I do if water is still coming in?
If it is safe to call, contact Pacific Restoration at (360) 327-8778. For a plumbing-source leak, the company will coordinate a plumber to stop the source before mitigation or drying and does not perform plumbing repair. If floodwater is rising or evacuation is necessary, follow emergency instructions first.
