Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

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.

You should ask a few questions to ensure that your potential lead removal professional is experienced and qualified to handle lead-paint abatement safely, legally, and properly.

• What are your qualifications and experience removing lead-based paint?

• Are you licensed and certified to remove lead-based paint?

• How do you test for lead paint?

• What methods do you use for lead-based paint abatement?

• What do you plan to do with the hazardous material when you remove it from the home?

• Do you do replacement and painting work or removal only?

Results from professional lead testing are typically available within a few days to a week (2-7 days), depending on factors like laboratory processing times and the volume of samples being analyzed. Expedited services may also be available for urgent situations.
