The short answer
Drinking Water Safety
Floodwater can carry bacteria, sewage, and chemicals into your water supply. If you rely on a private well, have the water tested for coliform bacteria, E. Coli, and nitrates. Boil water until the results come back clean.
Municipal water systems are typically treated and safe, but a flood can damage pipes. Your local water authority will issue advisories if needed. If you see discoloration or smell something odd, use bottled water until the system flushes out.
Well Water Testing
For well owners, testing after a flood is not optional. Floodwater can contaminate the well even if you see no damage. Contact a state laboratory to test for bacteria and chemical pollutants. The lab can guide you on what to sample.
You should also inspect the well cap and casing for cracks. If the well was submerged, assume contamination until tests say otherwise. Disinfect the well system with bleach and flush it before you take a final sample.
- Test for coliform bacteria and E. Coli
- Check for nitrates and chemical runoff
- Inspect well cap for damage
- Disinfect the well before retesting
- Follow local health department advice
Mold Testing in Your Home
Mold grows within 24 to 48 hours after water exposure. Testing for mold helps you know what kind is present and how widespread it is. You can buy a DIY kit, but a mold professional can take air and surface samples for a clearer picture.
Air sampling compares indoor spore levels to outdoor ones. Surface sampling identifies mold on walls, floors, and furniture. The results tell you if the mold is a health concern and guide the cleaning approach.
- Air samples for spore counts
- Surface samples to identify mold types
- Moisture readings in drywall and wood
- Check HVAC ducts for hidden growth
- Retest after cleanup to confirm success
Post-Remediation Clearance Testing
After the pros finish the cleanup, you should not assume the air is safe. Clearance testing checks that mold spore levels are back to normal and that moisture is under control. This step is especially important for homes with allergies or asthma.
A mold professional will take air samples and compare them to outdoor levels. They may also use moisture meters to ensure no hidden damp spots remain. If the test shows high levels, further cleaning is needed before you move back in.
When to Test
Test your drinking water as soon as possible after a flood, especially if you have a well. For mold, test within the first few days to catch early growth. Waiting too long can make the problem worse and harder to fix.
If you live in Euless, you know the humid climate can speed up mold growth. Act quickly to get samples taken. Your insurance company may require testing as part of your claim, so document everything with photos and receipts.
- Test well water within 48 hours
- Take mold samples before cleanup starts
- Retest after remediation is complete
- Keep records of all test results
- Check your policy for coverage details

Can I test for mold myself?
You can buy DIY mold test kits, but they often only tell you if mold is present, not the species or spore count. A mold professional can take air and surface samples for a more accurate assessment. For serious floods, professional testing is worth the cost.
How long does water testing take?
Bacterial tests for well water usually take 24 to 48 hours for results. Chemical tests may take longer. Mold air sampling results can come back in a few days, but lab analysis might take a week. Plan for a few days before you know the full picture.
Does my insurance cover water testing?
Policies vary, and your insurer decides what is covered. Flood damage is often excluded from standard homeowners policies, but if you have flood insurance, testing may be included. Check your policy and ask your insurance company about coverage for lab fees.
