How can you test for lead in drinking water?

2 How to collect samples?

To test for lead in drinking water, you need to collect samples from different locations and times of the day. You should follow the instructions provided by your local health department or a certified laboratory that can analyze your samples. Generally, you should collect at least two samples: one from the first draw in the morning, and one after flushing the water for a few minutes. The first draw sample represents the water that has been sitting in the pipes overnight, and may have higher levels of lead. The flushed sample represents the water that comes from the main source, and may have lower levels of lead.

3 How to store and send samples?

After collecting the samples, you should store them in clean, plastic bottles that are labeled with your name, address, date, and time of collection. You should also fill out a form that provides information about your water system, plumbing materials, and any symptoms or concerns you have. You should send the samples and the form to a certified laboratory as soon as possible, preferably within 24 hours. You should avoid exposing the samples to heat, sunlight, or contamination.

4 How to interpret results?

The laboratory will measure the amount of lead in your samples and send you a report with the results. The results will be expressed in parts per billion (ppb), which is a unit of concentration that indicates how many micrograms of lead are in one liter of water. The Environmental Protection Agency (EPA) has set an action level of 15 ppb for lead in drinking water, which means that if more than 10% of the samples exceed this level, the water system must take steps to reduce the lead levels. However, there is no safe level of lead exposure, so you should aim for the lowest possible level in your water.

5 How to reduce exposure?

If your test results show high levels of lead in your drinking water, you should take immediate action to reduce your exposure and consult your doctor. To do so, use cold water for drinking, cooking, and preparing baby formula since hot water can dissolve more lead from the pipes. Additionally, run the water for 15 to 30 seconds before using it, especially if it has been sitting for several hours. You should also consider installing a filter that is certified to remove lead from your faucet and replacing it regularly according to the manufacturer's instructions. Furthermore, you should replace any lead pipes, faucets, or fixtures in your plumbing system with lead-free materials or hire a licensed plumber to do so. Finally, contact your water provider or health department to find out if they offer any programs or assistance to reduce lead in drinking water.

6 How to monitor lead levels?

You should test for lead in drinking water at least once a year, or more frequently if you have made any changes to your plumbing system or water source. You should also keep track of your test results and compare them over time to see if there are any changes or trends. You should also be aware of any notices or advisories from your water provider or health department regarding lead in drinking water, and follow their recommendations. By testing, reducing, and monitoring lead in drinking water, you can protect yourself and your family from its harmful effects.
