When the water in your tap becomes contaminated, the American Water Supply Association recommends that you test for contaminants and follow the instructions for testing at your local water treatment plant.
The American Water Treatment Association (AWTA) offers a detailed guide to testing your water, but if you’re unsure about your drinking-water treatment plant, here are some things to consider.

The American Public Health Association recommends testing for contaminants at home, as well.
In addition to your tap, a few other places you can get tested for harmful contaminants include: home-based wells (such as wells near your home), plumbing fixtures, outdoor faucets, and even the roof of your home.
If you can’t locate the source of your contamination, you can ask your doctor or other health professional for guidance on how to test for the presence of harmful contaminants.
What can I test for?
To find out how much of your tap is affected by harmful contaminants, you should test for several different contaminants.
There are two types of contaminants you should be looking for: contaminants that cause illness or injury to people, such as viruses and bacteria, or contaminants that don’t cause illness, such “other” contaminants that are more toxic or carcinogenic, such nitrates, perfluorocarbons, and polychlorinated biphenyls (PCBs).
You should also test for water quality (water hardness) and other environmental pollutants that can affect water quality.

There’s no way to do all the tests and tests on your own, and the time required to test each sample varies depending on the type of contaminant, the time of year, and your location.
You can’t always rely on testing kits from your water supplier or other third-party companies, so if you have questions about testing your tap water, ask your water supply company.
How to test your water at home: If you don’t have a local water supply or don’t know the source, your local public water supplier will test your tap for contaminants.
The water in a well or well-treatment plant can be contaminated by harmful bacteria, viruses, and other pollutants.
The well or treatment plant should test every 3 months, to ensure your water has been tested every month.
You should test your drinking and other tap water at least once a year.
If your water source tests positive for a harmful contaminant and you suspect a contamination has been occurring, you may need to test more frequently.
The EPA recommends testing every two weeks to ensure that your tap has been cleaned of harmful contamination.
In some cases, the testing may be delayed for a week or more.
The treatment plant may also test your well water for harmful contamination every three to four months.
How do I test my tap water?
You can test your taps by using a test kit from a water supplier, or you can buy one yourself.

To test your home-basin well water, you’ll need a test filter.
You may be able to buy one online, but many water filtration systems use expensive cartridges, which can be expensive.
You’ll also need to have a well-filter on hand to filter the water.
To use a test bottle to test the water, place the filter inside the bottle and put the water sample into the test tube.
If the water comes back positive for any harmful contaminants, you’re likely to need to re-test your tap and/or well water at your tap.
What if I need to change my water?
Depending on where you live and what you’ve installed, your tap might be clean for only a few days or weeks, or it may take a few months or years for your tap to be clean.
Read our article Testing the water at the source and using a tap test kit can help ensure your tap isn’t contaminated.
You might also be able.
Some contaminants may be more easily washed out than others, and that’s why it’s important to test frequently to make sure your tap remains clean.
If it’s possible to test by home, it’s a good idea to do so because a tap will be cleaner when the water is tested by the home-testing lab.
How often should I test?
Your water test results are sent to the treatment plant or water treatment facility where you install your tap system.
When the treatment facility tests your tap in the coming months, it’ll determine how many samples it needs to test.
Some companies, such for example, water purifiers, will test at your home when they install your water treatment system.
Others, such in your local home, may test once or twice a year at your water plant.
How long will the testing take?
The treatment facility will send the results of your water test to the EPA for processing and distribution.
The process is known as sampling.
