Quick Answer
To determine if your well water is safe to use, you'll need to test for bacteria, nitrates, and other contaminants that can affect health. You can hire a certified water testing lab to perform a comprehensive analysis, or use DIY test kits. If levels exceed the safe limits, you'll need to take corrective action.
Testing Your Well Water
The first step in determining the safety of your well water is to collect a water sample from your well. This typically involves using a sterile sample bottle and a submersible pump or a bucket to draw the water from the well. Once you have the sample, you can send it to a certified lab for analysis. The lab will test for a range of parameters, including bacteria such as E. coli, total coliform, and fecal coliform.
Understanding the Test Results
When you receive the test results, you’ll want to focus on the parameters that are most critical to health. For example, E. coli and total coliform bacteria can indicate the presence of human or animal waste in the water, while nitrates can be a sign of agricultural runoff. If the levels of any of these parameters exceed the safe limits, you’ll need to take action to correct the issue. For example, if the E. coli levels are too high, you may need to shock chlorinate the well to kill the bacteria.
Corrective Action
If your test results indicate that your well water is contaminated, you’ll need to take corrective action to make it safe to use. This may involve installing a new well casing or screen, or using a treatment system such as a reverse osmosis filter or an ultraviolet (UV) disinfection unit. It’s also a good idea to retest the water after any corrective action to ensure that the levels of contaminants have been reduced to safe levels. In some cases, you may need to hire a professional to inspect and repair your well.
