How To Know If Your Well Is Running Dry: The Warning Signs

Always having clean cool water from a well is usually taken for granted. Until one day it changes.

It doesn’t seem possible to run out of water from a well, but it does happen. When it happens it is never overnight, however.

There are always warning signs that it is about to run dry. If you are aware of the signs, then you will recognize in advance that it is about to happen.

In this article, I will go over those signs to watch for and also what could be confused for a dry well. Nothing is ever cut and dry so read on to see if your well is actually running out of water. Then, a few thoughts on how to fix a dry well.

Signs that you’re running out of water

You could be just having a problem with the pump, or the casing leaking. I’ll talk more about that later in the article, but for now, take a look at these signs of a well running dry and see if any of them are familiar.

The Well is Pumping Air

If you turn on a fixture like a faucet or a shower and it blasts air, then something is wrong.

It’s likely that the water level has dropped and there is air getting pumped in with the water.

This is not a sure sign as it can be a faulty pump, but it is something to set the alarm bells ringing and needs to be checked out.

Your Water Is Sandy Or Muddy

When the water sputters out of the tap and also looks like it has some sediment, then it could mean that your well is about to run dry.

Some wells have sediment even when they aren’t running dry. Many people use a sediment filter for their well water since a pump is usually located near the bottom of the well. 

Murky or sandy water on its own is not a sure sign. However, if you have a filter and it still has lots of sand and you’re seeing some of these other signs, then it is time to be concerned. 

If you don’t see any other signs besides this one and don’t have a sand and sediment trapper, then this is a good time to get one.

The Pump Is Always Running

As your water level gets lower, the pump will struggle to build up enough pressure to get the water out. You’ll hear the pump on for much longer than it used to.

Another sign is the pump switching on and off continuously. Usually, the pump is deep under the water, but when the level drops, it is always trying to get that water into the pressure tank.

Water Tastes and Smells Funny

The bottom of your well is a murky place. If your water is low, then the sediment gets kicked up and swirls around the pump. Ordinarily, this would be undisturbed at the bottom of the well and the pump would have plenty of clean, fresh water to pump.

If the water looks yellowish, then this usually means that there are some organic particles suspended in the water. Water level dropping to the bottom can cause this to happen.

White or cloudy water means essentially the same thing but it can also include non organic sediment.

This can be caused by agricultural contamination. If you have a farm nearby then this could also be the cause of your well running dry since there will be more pressure on the water table.

Neighbors Also Report The Same Problems

If any of these issues start to happen out of the blue then ask around your neighborhood. If your neighbors are also well owners then they will have the same issues. They are accessing the same water after all.

If they have the same problems then chances are it is a problem with the aquifer.

You’ll need to check your water level to see what you are looking at. 

How To Check Your Well Water Level

Don’t use the ice cube trick! Let me get that out of the way. Some people will tell you to drop an ice cube down the well and count how long it takes to hit the water as a well water level indicator.

Not only is this method not accurate, but you risk contaminating your well. Ice cubes, especially from an ice cube machine on your fridge, are notorious for containing bacteria and mold.

Instead, use a water level meter to accurately test it. Solinst make the most reliable ones and can be purchased from Amazon. I think every well owner should have one as you never know when you will need it.

Checking the water level is the first thing you should do when you see any of these signs. If your level is low, then your well is running dry.

If your water level is fine then read the next section as it details what the issues might be.

Why would a well stop working?

If your well has suddenly stopped working, then that is due to a mechanical issue and not that your well has run dry.

You’ll see all or most of those signs I listed above when your well is running out of water. It can happen quickly, but not suddenly and without any warning signs.

Sometimes people think that their well has run out of water when the problem is actually a faulty well pump. It could be that the pump is broken or clogged. Another possibility is that your pressure tank is too small for your water demand.

The first thing to figure out if you are not getting any water is if those are factors. Check to make sure that your pump and tank are working properly and have power.

What to do when water well runs dry?

Before you make any decisions, contact a well professional in your area. They will give you the best advice based on your unique situation.

Here are some things that you’ll likely have to decide after consulting with a pro:

• Cleaning the sediment – Over the years, your sediment at the bottom of the well builds up. If it has accumulated to the point that your well is shallower than ever then you can have it cleaned. 
• Lower the pump – If you have a lot of new neighbors that also have well, or a new business that uses lots of water, then your aquifer may be stressed. In this case, you may be able to solve the problem just by dropping the pump down lower into the well.
• Deepen the well – You may need to dig down further to access more of the water table.
• Dig a new well – There could be another spot on your property that allows easier access to the aquifer underneath. We had three wells dug before we got the right spot that gave us enough water. You may be running out of water because of the location. If your well is relatively new then this is probably the issue.
• Hydrofracking – The worst case scenario is that the water is blocked in the rocks and fracking is needed to open them up. For about the same cost as digging a new well, you can hydrofrac instead. It may not be an option in the area where you live, however.

Why do wells go dry?

If your well goes dry, it doesn’t mean that you will never have water in it again. The recharge frequency depends on a few things, so you may have to wait it out.

Here are some issues that cause wells to run out of water, even if only temporarily.

Drought

Wells are not underground lakes. A well is just an opening in the rocks or soil that collects water that is underground. As such, it is highly dependant on precipitation.

Drought conditions will impact the well water level. How quickly it replenishes after it rains or snows depends on the material where your well is located.

Too much pressure

If there is some new construction nearby and lots of people are drawing water out of the same aquifer, then this puts too much pressure on the water table. It can take a while for the water to recharge in your well depending on how many people are now using it. 

If a new farm started operating since you got your well, then this will have a major impact.

A new housing development in your area that uses well water will also impact how much water is in the aquifer. 

Environmental changes

This ties in with drought, in a way. A drought may temporarily affect your well if it doesn’t last long. When the overall environment changes, it may not allow the well to replenish the water. 

The environment may be permanently in a drought phase due to climate change, a river being dammed or diverted, over-irrigation for agriculture, or some other reason. Once the aquifer is depleted, it may not make a comeback.

A demographic shift could also be to blame if a city grows too quickly.
