Allow chlorinated water to stand in the well and pipes for at least 8 hours (preferably 12 to 24 hours). Run water from outdoor faucets to waste (away from desirable vegetation) until the chlorine odor is slight or not detected at each faucet. Then run indoor faucets until there is no chlorine odor.
How long does it take to chlorinate a well?
A very shallow well can flush in as little as 30 minutes, while deep wells can take up to 24 hours. During shock chlorination, the chlorine will also pass through a home's entire plumbing system.
How long does it take to flush out a shocked well?
It will usually take 4 to 8 hours to flush the well after a standard well chlorination. The water may become discolored during flushing because the chlorine may have loosened the hard water deposits in the plumbing. Caution: The chlorine must be completely flushed from plumbing system.
How long after shocking a well can you drink the water?
Wait one to two weeks after shock chlorinating the water supply system to retest for total coliform and E. coli bacteria. Follow sample collection instructions carefully. If the test results show the absence of coliform bacteria, the water is safe to drink.
What is the best way to treat well water?
Yes, boiling is the surest way to kill bacteria, viruses, and parasites in the well water. To boil the water so it will be safe, heat it to a full swirling boil. Keep the swirling boil going for at least one minute before you use the water. Store the boiled water in a clean, covered container in the fridge.
Can you shower after chlorinating well?
Keep in mind that doing laundry and taking a shower cannot be done for at least 24 hours with a chlorinated well. Waiting a few days to do these is a good idea. We recommend using unscented bleach for this process and using a chlorine test kit from your local supply store.
How much does it cost to chlorinate a well?
To disinfect your well and eliminate the bacteria, you should chlorinate the well. You can hire a company that services wells to do the chlorinating. The cost ranges from $80 - $200. You can also perform the task yourself.
Why does my well water turn brown when I add bleach?
The brown is the iron in the water that has oxidized as a result of the chlorination. Normally, the iron in water is in ion form and does not display itself until it combines with oxygen and forms common rust which turns the water reddish-brown.
What happens if you put too much bleach in well?
According to AskingLot, if you put too much bleach in your well, it can destroy the good bacteria found in the well, which can be a significant problem! The company also says that you should dilute the bleach with water so the pipes do not get ruined.
What does it mean when your well water turns brown?
When water collects and remains in iron pipes too long, it can create what is known as iron water. A proliferation of iron causes water, sink, and clothing stains and impacts your water's taste, smell, and appearance. One form of iron water is manganese, which causes brown or black tints to water and a bitter taste.
Is it safe to put bleach in well water?
You can disinfect your well with household chlorine bleach such as Clorox, Purex or a generic brand. The chlorine in the bleach kills bacteria. Note that it may take more than one chlorination for your well to return a satisfactory test.

Can wells be used in the future?
Wells that are not currently being used, but might be used in the future, must be continuously maintained like a working well.
How long does a well last?
In sum, there is no simple short reliable answer to how long a water well will continue to give good quality and acceptable quantity of water, but our experience is that driven point wells have minimum flow and shortest life in many areas as the well point clogs, and driven point or drilled wells into bedrock in areas of very high mineral content water may begin to show clogging and reduced water flow in as little as a decade.
What are the features of a well?
Mineral level and type of minerals in water supply, or amount of sediment in the water supply are important features in the life expectancy of a water well. In areas of hard water, minerals in the water tend to clog the rock fissures through which water flows into the well - harder water clogs the fissures faster, reducing well output.
What is a well casing?
Well casings: modern drilled wells for residential use typically include a 6" diameter steel casing which is inserted into the drilled well and down into bedrock. The casing is sealed around its exterior to keep (often unsanitary) surface runoff or surface contaminants out of the well interior.
What causes a well to stop delivering water?
Air leaks: Well piping or equipment can develop an air or water leak and stop delivering water or reduce water delivery at any time.
What equipment is used to get water out of the ground?
First let's make clear that we're talking about the well itself, the hole in the ground and its ability to give an adequate quantity and flow rate of drinking water, not the equipment used to get water out of the ground, such as the water piping, water pump, pump controls, water tank or valves.
Can a well be used for drinking water?
The issue of water potability - can it be used for drinking - is separate from the ability of the well to deliver water at all, but beware: a well with a good flow rate and good potability can change in both of those factors.
Can copper be used inside a well?
Copper water piping is not usually used inside of a well nor between a well and the building but is commonly used for in-home water piping. The corrosivity and mineral content can affect the life of copper piping as can the quality and thickness of the copper itself.

Why do wells need maintenance?
Water wells require regular maintenance to ensure adequate water flow and optimum water quality. As a water well ages, the rate at which water may be pumped (commonly referred to as the well yield, flow or performance) tends to decrease, especially in wells that were not properly developed when first drilled.
What is the purpose of a well rehabilitation?
A successful well rehabilitation will maximize the flow of water from the well. The chances for successful rehabilitation are dependent on the cause (s) of poor well performance and the degree to which the problem has progressed.
What is the principal means used for rehabilitation of chemical incrustation problems?
The principal means used for rehabilitation of chemical incrustation problems involves the use of strong acid solutions to dissolve incrusting materials.
How to detect deterioration of well performance?
To detect deterioration of well performance, you must have a point of reference. Often this reference is the original well construction and pump test data which are normally supplied to you by the well driller on a well completion report or well log when the well is installed. However, even if you do not have this information, significant changes in your well are also a warning sign. Major changes in any of the following well characteristics is an indication that your well or pump is in need of attention:
What information should be included in a water well completion report?
Water well completion report or log (if you have it) which should include information such as water well depth, date drilled, construction (including casing specifications, grouting and screen), and water well yield or flow rate in gallons per minute (gpm)
What does a decrease in well yield mean?
Generally, a decrease of 25% or more in well yield indicates that rehabilitation is in order. Delaying rehabilitation procedures can significantly increase costs and in some cases make rehabilitation impossible. To detect deterioration of well performance, you must have a point of reference.
Why does water flow decrease as wells age?
As a water well ages, the rate at which water may be pumped (commonly referred to as the well yield, flow or performance) tends to decrease, especially in wells that were not properly developed when first drilled. A drop or complete loss of water production from a well can sometimes occur even in relatively new wells due to a lowered water level from persistent drought or over-pumping of the well which can dewater the water-bearing zones. More often, reduced well yield over time can be related to changes in the water well itself including:
How long do well pumps last?
Typically, well pumps can last between 8 and 15 years.
How does a pump affect its lifespan?
Aside from the quality of the actual pump, the pump’s power supply can also affect how long the pump will last. Too high or too low voltages can reduce a pump’s lifespan and even destroy it. Phase imbalances or loss can have a similar detrimental effect.
What are the different types of well pumps?
If you’re in the process of buying a well pump, or you already own a well pump but don’t know much about it, there are three common types of well pumps you’re likely to come across in the US: centrifugal well pumps, submersible well pumps, and jet well pumps.
What is the most efficient well pump?
A submersible well pump is considered the most efficient type of well pump, and, for that reason, the most popular. A submersible pump operates only when needed, rather than constantly drawing water into the home. Submersible pumps use a spinning impeller to draw water into the pump and through to the surface. You can use submersible pumps in shallow and deep well applications.
How deep can a well pump be?
Commonly combined with a pressure tank, jet well pumps can be used to obtain water from deep and shallow wells. The design of jet pumps depends on the well in question – while a shallow well of around 25 feet will use a single pipe to draw water, a deep well will require a two-pipe system. Two-pipe jet well pumps are capable of drawing water from more than 100 feet below ground level.
What causes well water to wear out?
Sediment and sand are commonly found in well water. The more sediment in your water, the faster the pump’s internal components, including the well pump motor, will wear out. High mineral content can also cause wear and tear to the well water system, and can even end up clogging the pipes, chambers and ports.
What happens if you cut corners on a well?
Cutting corners or missing out on important aspects of installation might result in premature pump failure, so it’s very important to find a qualified contractor who knows the ins and outs of well system installation.
How long does a well pump last?
You should expect a good well pump to last 8-15 years if it’s maintained correctly. The exact lifespan of the well pump depends on the factors listed above and how well you look after the device. A submersible pump should last longer than a non-submersible because there is less impact on the device. This reduces the wear and tear and makes it less likely the pump will stop working prematurely.
How much does it cost to replace a well pump?
It will typically cost between $500 and $2000 to fully replace your well pump and pressure tank, depending on the exact size and specifications.
What is the difference between a 2 wire and a 3 wire well pump?
2-Wire well pumps have all the wiring within the pump itself , whereas 3 wire well pumps need a separate control box for the pump to operate. This means if the pump stops working, it's a lot easier to troubleshoot with the 3 wire because it's separate from the pump, but with a 2 wire, you'll need to take the whole pump up and check it all over.
Why is it important to install a well pump?
How your well pump is installed is as important as the pump itself. If it’s not installed correctly and doesn’t have the correct valves, or proper electricals in the right place, then it won't function correctly. This will lead to the well pump breaking down a lot sooner than usual.
How to check if a well pump is working?
The easiest way to check a deep well pump is to use an Ohm meter to make sure electricity is running as it should. This video shows you how.
Do well pumps last forever?
There are jet pumps for deep wells and non-submersible pumps for shallow wells. However, even the best well pumps won’t last forever, and it’s important to know what to realistically expect from yours.
Can sediment build up in a well pump?
Trace amounts of sediment can be found in most water, and over time it will build up within the well pump. Sand can have a significant impact on your well pump because of its abrasive qualities. It can damage your motor, the components and everything within the pump.
How long should you leave chlorine solution in a well?

How long does chlorine kill bacteria?
Chlorine should have enough contact time to kill the bacteria. Make sure that no one in your home uses the water for any purpose during the 12 to 24 hour treatment. Preventing electric shock from the water pump. Before removing the well cap or cover, turn the pump circuit breaker off.
How long after shock chlorination can you drink water?
Wait one to two weeks after shock chlorinating the water supply system to retest for total coliform and E. coli bacteria. Follow sample collection instructions carefully. If the test results show the absence of coliform bacteria, the water is safe to drink.
What is an improper well location?
an improper well location. absence of a well cap or an improperly placed or loose well cap. inadequate grouting or other faults during well construction. a cracked well casing. Shock chlorination is NOT a recommended method for treating recurring bacteria problems.
Why is my well water cloudy?
whenever the well is surrounded by flood waters (standing water around or covering the well casing) if well water becomes muddy or cloudy after a rain. if the well has iron bacteria or sulfur-reducing bacteria symptoms like slime (biofilm) or odor.
