When a storm system dumps water on the ground, the news usually stays on the headlines. In a report on the Four Corners region of the US south-west, The Guardian described the area as having endured "days of rain that forced evacuations", with more heavy showers and thunderstorms expected after that. For most city residents, a flood story like this sends the water question to the utility. If you run a private well, that question lands on your own doorstep.
You do not need to panic, and you do not need to drink or cook with water you have not checked. You need a short, ordered routine, and it starts with a walk outside.
Start Outside at the Wellhead
Walk to the well before you turn on a tap. Look at the well cap and the top of the casing. The cap should sit snugly, its seal should be intact, and any vent screen should be whole and free of nests or debris. Notice whether water has pooled around the wellhead, whether soil has washed away from the base, or whether the ground has shifted. Check the electrical box and pump wiring for water damage too, because a damaged pump circuit can turn a simple inspection into a safety problem.
If the wellhead has been under standing water, do not open it yourself or reach into it. Call a licensed well contractor. A visual check can tell you something useful, but it cannot tell you the water is safe to use.
Trace Where the Runoff Goes
Floodwater moves downhill, and it carries whatever it picks up. Think about the low spots on your lot, the driveway that channels rain toward a certain corner, the compost pile or animal pen that sits upslope, and the location of your septic system relative to the well. You cannot change the terrain, but you can note which features lie in the path. That list tells you what to ask a laboratory to check and what to watch over the coming weeks.
Test After the Water Recedes
A flood-season test is different from the routine test you may run once a year. Contact a state-certified laboratory and ask which analyses fit your situation. Bacteria testing is often a sensible starting point after heavy rain, because it helps show whether surface water may have reached the well. Ask the lab for sampling bottles, the proper handling steps, and the turnaround time before you collect anything. Follow the lab's instructions exactly, since a sample collected or stored poorly can give you a misleading result. Write down the date and time you collected the sample so the result can be matched to the conditions that existed then.
Follow Local Guidance Without Guessing
If your county or state health office issues a notice about water use, follow it as written. Do not rely on a neighbor's word or an old rule of thumb about how long a well stays affected. Notices can change as new results come in, so check for updates rather than assuming the first one still applies. If you are unsure whether guidance covers a private well, call the health office and ask directly. Office staff can tell you which parts of a notice apply to your property and which do not.
Hold the Filter Decision Until You Have Results
It is tempting to buy a filter as soon as the weather news turns serious. Resist that urge until the test tells you what you are treating. A filter sized for one problem can leave another untouched, and a disinfection step may matter more than a sediment cartridge after a flood. Match the equipment to the laboratory report, not to the storm headline, and keep the receipt and the report together so you can show exactly what the equipment was chosen to address.
Keep a Flood-Season Log
Write down the date of the storm, the condition of the wellhead, photos of any damage, the laboratory name, the sample date, and the results. Store the file where you can find it during an emergency. A plain notebook or a shared folder works well. When the next storm arrives, you will have a baseline instead of a guess, and you will be able to tell whether something has changed.
The forecast for the south-west will keep changing, and so will the weather where you live. Your well checklist does not have to change with it. Walk the wellhead, trace the runoff, test with a certified laboratory, follow official notices, and then decide what the water actually needs.
