Why Is My Water Cloudy After it Rains?

Florida has had a rainy, rainy year this time around. Bay County alone has had its wettest year in over two decades. After all that flooding in October, you might have questions about your well during heavy rain. If you have standing water on your lawn after a rainstorm, that’s usually not something to worry about. After all, that’s how rainwater enters your aquifer and provides you with water in the first place. Your home water supply may become cloudy after heavy rain if you have a well, though.

Water that is clear every other time but becomes cloudy after rainfall can cause serious problems. Usually, this will be a problem with your well or septic system. Since both are essential, you need to have this problem checked immediately.

Rusty plumbing can also cause cloudy water, especially brown or reddish water. Rainwater can enter your well and create cloudy water if your well leaks. The most dangerous color may be brown or grayish, which could show a septic contamination issue. There might not always be a bad smell or taste, but it’s more common with septic issues.

This is why a color change necessitates that you take it seriously.

What Do I Do About Cloudy Water After Rain?

Before doing anything else, rule out problems that aren’t related to your well. For example, check the plumbing to ensure that the plumbing rusting over isn’t the problem. If both hot and cold water runs brown, that can signify rust in the pipes. If you have CPVC pipes and the whole house still produces brown water, it may be a well issue.

Potential Causes


When surface water moves along the natural runoffs on your property, it can reach the well. If there’s a break in the seal or a leak at the pipe or wellhead, your water can become contaminated. If you have an opening in your wellhead, you’re at serious risk of getting sick. When rainwater enters your well, it carries bacteria, nitrates, and fertilizer into your water. You may as well be drinking water off your lawn at this point!

Septic Contamination

Suppose somebody near your well uses a septic tank; whether you or a neighbor, it might be compromised. We’re sure you can imagine how bad this can be for your health. So you will want a bacterial test to measure what’s in your water.

Fecal coliform, e-coli, and other bacteria will indicate the need for a septic professional. Call them and arrange a full system-wide test. If you can take care of this early, you can prevent serious issues.

What Next?

Test Your Water

No matter the cause, if the color isn’t from the plumbing system, you need to test your water. The risk presented by a leaky septic system is so grave you need to rule it out or address it. Complete water profile tests will tell you exactly what’s in your water. Whether it’s e-coli, mineral content, dissolved solvents, or other contaminants, a test will find it.

Check Your Wellhead

While you’re at it, make sure to examine your wellhead. Be sure the well cap is flush with the casing and that the seals are tight. You should also check the visible well casing for cracks. Grout can also allow water runoff into the well, so be sure everything is fresh and well maintained.
