Determining if your water main contains lead involves a few steps. First, check the age of your property, as homes built before the 1980s might have lead pipes. Contact your water utility company for information on your service line material. Then, you can hire a professional plumber to conduct an inspection or use a lead testing kit to analyze water from the main line.

According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

No, a standard home inspection includes the basics and does not offer lead paint testing. Professional lead paint inspectors need specific licenses to perform these inspections, which not all home inspectors have. If you suspect lead paint in the home you are about to purchase, you will need to pay separately to have that done. If the findings come back positive, you may be able to negotiate with the buyer to cover the cost of the removal.
