How you test for lead in your water depends on the source of your home's water supply. If you have municipal water, your local water system may offer to test the water for free or may connect you to a lab that will perform the testing.

If you have a private well that provides drinking water, you are responsible for testing it for lead. Look for a lab that is accredited by your state's Department of Environmental Protection to perform the test.

“Testing” can start with your senses: Assessing your water’s appearance, taste, and smell can all be good first steps. The best way to know for sure what’s going on with your water is to use a well water testing kit, which can tell you about the specific levels of bacteria, dissolved solids, and hardness of your water with precision. Have a pro test your well water at least once per year.

The average cost of a lead paint inspection is about $600, but it can cost as low as $150 or as much as $800, depending on the size of the area, geographic location, and the inspection methods. Some of the most common lead paint inspection methods include:

• Visual inspection: $150–$400

• Paint sampling: $200–$600

• X-ray fluorescence (XRF): $250–$700

• Risk assessment: $300–$800

You do not have to remove lead paint if the surface is not chipping or peeling or if there are no pregnant people or children under the age of six who live in or regularly visit your home. Lead paint is a particular risk for young children whose brains and bodies are not fully developed. Experts strongly recommend that you call a pro to remove lead paint if it’s peeling or flaking, no matter who lives in the home. You can experience lead poisoning by breathing in or ingesting just a small amount of it.
