If you’ve experienced flooding, your first thought might not be your well water contamination after a flood. But honestly, it should be. Floodwater and well safety concerns are critical because floodwaters carry all sorts of things—chemicals, bacteria, and even sewage. Once these contaminants get into your well, the water you depend on might not be safe. So, how do you know if your well water is still good to drink? What happens to well water after flooding? Let’s talk about it.
Flooding doesn’t just cause visible damage to your yard or home. It seeps deep into places like your well. And that’s where the real trouble starts.
Do you know how floodwaters can carry debris, dirt, and sometimes much worse? Imagine all that seeping into your well. Wells, even sealed ones, aren’t invincible. The water flowing in can pull in bacteria, viruses, and chemicals that don’t belong there. And it only takes a little contamination to turn your water from safe to dangerous.
Here’s the thing: contaminants like E. coli, nitrates, and other bacteria can enter through cracks, or if floodwaters rise above the wellhead. That’s why your wellhead should be at least 18 inches above ground and fully sealed. But if the floodwaters go higher, you’re playing with fire.
So, how can you tell if your well water has been compromised? Sometimes it’s obvious, like muddy or cloudy water. Other times, it’s more subtle.
These signs tell you something’s off, but they can’t tell you what exactly. You’ll need a test for that. But let me explain how to get that done.
Testing your well water is the only way to know for sure what’s going on. And you can’t just eyeball this one. You need a certified lab test for well water to check for harmful bacteria in well water after a flood and chemicals.
Start by taking a water sample for well testing. It’s best to let a professional handle this, but if you’re doing it yourself, make sure the container you use is sterile. A sterile container for water sampling ensures you don’t introduce anything new into the sample that might give you a false result.
Then, take that sample to a certified lab for water testing. They’ll test for things like E. coli and well water contamination, nitrates, and chemicals. These are the usual culprits that cause issues after a flood, often leading to contaminated well water after flooding.
If bacteria in well water after a flood are found, your well may need to be chlorinated (shocking a well) to get it back to safe levels. Chlorinating a well after a flood kills off most of the harmful stuff. It’s a process you can DIY, but honestly, it’s easier and more effective when done by a pro like Four Seasons Plumbing. They’ve got the expertise to get it right the first time when dealing with well water safety after a flood.
Let’s say your test results show contamination—now what?
You’ve got a few options. The quickest fix for bacterial contamination is chlorination. Essentially, this process flushes chlorine through the well system, killing bacteria. But there are other steps you might need to take too, depending on the contaminants found.
Luckily, Four Seasons Plumbing can help you with all of these. They install filtration systems and can perform chlorination treatments to get your water back to being safe.
We’ve talked about the dangers, the signs, and how to treat contamination, but let’s not stop there. You can take steps to protect your well in the future. Here’s how.
Four Seasons Plumbing offers well-maintenance services to keep your system running smoothly, whether you’re dealing with a flood or just want peace of mind. They’ll handle inspections, water testing, and any necessary repairs to keep your water safe.
Here’s the bottom line: If your well water looks, smells, or tastes off—or if there’s even a small chance it’s been contaminated—you need to act fast. Don’t take any chances. Get it tested.
If you’ve already had a flood, you might be thinking, “Well, my water looks fine, so it’s probably okay.” But the truth is, you can’t always see contamination. That’s why testing is critical. Even if everything seems normal, contaminants like bacteria don’t always make themselves known immediately.
Call Four Seasons Plumbing. They offer professional well water testing and can treat any issues that come up. Whether it’s chlorination, filtration installation, or simply a routine inspection, they’ll make sure your water is safe for your family.
If you’ve experienced flooding, it’s important to make sure your well water is safe after a flood. In our area, wellheads should be at least 18 inches above the ground and fully sealed. However, if floodwaters have risen above the wellhead or there’s a chance that contaminants may have entered the system, it’s time to get your water tested.
Take a sample to a certified lab to check for bacteria or other pollutants in well water. If bacteria are found in well water, your well may need to be chlorinated (also known as shocking a well). Another option to keep your water free from harmful bacteria is installing a UV light filter for well water purification.
So, don’t take any chances—get your well water tested today to ensure it’s safe for your family. Call Four Seasons Plumbing to schedule a professional well water test and protect your water supply after the flood. Safe drinking water post-flood is vital for your health and well-being.
