The Long-Term Consequences of Lead Exposure

Exposure to lead can cause devastating long-term health problems for you and your family.

Health Risks of Lead Exposure

Lead is a naturally occurring toxic metal that can cause serious health risks, including neurological, cardiovascular, kidney, and reproductive issues. Certain groups of people are especially vulnerable, including:
  • Children: Exposure can cause permanent cognitive damage, including lower IQ and behavioral problems.
  • Pregnant women and unborn babies: Lead moves through the placenta and can cause significant health risks for the fetus, including miscarriage, stillbirth, and brain damage.
  • Anyone with bone disease or bone injury: Anyone with bone disease or a broken bone can have additional lead released into the body as their body works to heal the bones.

Dust Wipe Samples

Used in Environmental Protection Agency (EPA) and Housing and Urban Development (HUD)-regulated inspections. Dust collected from required surfaces with a sterile wipe and placed into a sample container.

Icons 11

Paint Chip Sampling

Used in Occupational Safety and Health Administration (OSHA)-regulated testing and specific inspections. Clean utility knife used to remove all layers down to the bare substrate and sample sent to a lab for testing.

Common Lead
Exposure Sources

Lead-based paint & floor stains ( especially in homes built before 1978)

Soil contamination (particularly near airports or high-traffic areas)

Older plumbing (especially 1960s and prior)

Imported goods (ceramics, toys, jewelry)

Occupational exposure (brought home on clothes/tools) Stoves

Lead dust (Especially during Renovation, Repair and Painting, or RRP, in older homes)

Lead-Certified Pro Tip: In older homes, pay special attention to “mouthable surfaces” (window sills, banisters, stair treads, doors), where young kids are mostly likely to chew and be exposed to lead.

Common Misconceptions about Lead-Based Paint

“If my paint isn’t peeling it’s not a problem.”
 FALSE Lead-based paint can quickly become a problem if it’s disturbed in any way. Small actions like opening a window or walking on lead-based stained floors can disturb the paint and expose lead.
“My child looks fine, so they aren’t affected.”
 FALSE Lead poisoning can be asymptomatic for years.
“Dusting gets rid of lead.”
 FALSE While regular dusting is important, only HEPA vacuums and special detergents can eliminate lead dust.
“Painting over lead fixes it.”
 FALSE You must use proper encapsulation methods and approved products that won’t chip and re-expose the lead down the road.
“Any contractor can handle lead paint. ”
 FALSE Only lead-certified professionals can legally remove lead hazards. Someone who isn’t certified can actually increase contamination.

My heart goes out to anyone having to shop for post-disaster environmental testing, but I can enthusiastically recommend Jeanine and her team at M.A.R.S., especially to people dealing wildfire/WUI fire smoke damage.

Our house was in the heart of the Eaton Fire. It was left standing but smoke damaged. For four months, our insurer downplayed the health risks, offering to essentially wet wipe the walls and vacuum our bed after their own test found lead. They didn't address VOCs, SVOCs, heavy metals, though.

We knew that getting our own testing was the only way to push for a more thorough remediation. M.A.R.S came highly recommended by fire survivors in Colorado, also by local word of mouth, even by other industrial hygeniests and folks at United Policy Holders.

Jeanine fit us into one of the weekend trips she'd been doing to the Eaton Fire Scar this spring. And she tailored our tests to address our needs for our claim, and our financial limits. She asked for our prior test results so she could make sure she was only running tests we needed.

On the day, she showed up early. I was thrilled when she said we didn't need to enter the house. Also, her team wore protective gear. (For four months, everyone -- the insurance adjuster, other IH's, and others -- would enter the house casually, often with no masks or PPE, as if it were no big deal. I felt subtly peer-pressured to go in unmasked myself, to take and wash things, and now regret it.)

The results took a while, but the labs have been swamped, and M.A.R.S. was in touch. And when the results did come in, the level of detail and care with which Jeanine laid out her report was remarkable. And her explanations of results rigorously supported her recomendations. She included and referred to all the prior results. And she is up to date on current and emerging science and standards.

In many ways, the new results were bad news (the highest levels of Dioxins she'd seen in the area as well as Beryllium, which we're now learning has shown up in unprecedented levels in the Eaton Soot and Ash), but at least we are now armed with data.

I'm trying to think of constructive criticism, but I really just feel gratitude for Jeanine, Rebecca, and the whole team.

We're still going to have to fight to get the insurance to follow her recommendations so it's all still an ongoing nightmare. That said, the two moments of greatest relief I've felt since the fire were, first, when the M.A.R.S. team showed up at our house, and then later, when Jeannine sent our results. She's smart and talented, and I believe that she does this work because she genuinely cares about protecting people's health. She's a methodical hero :), a literal lifesaver!

Just hired MARS environmental to do a meth test for a home we have under contract. They got me setup with an appointment fast. The tester arrived on time, was friendly and explained everything. I recommend!
Rachel Courtney

I loved how responsive MARS was! I filled out the "contact us" form on their website and heard back via email within 24 hours. We scheduled a same-week appointment. I was emailed an estimate and invoice. They requested a deposit of $100 on a $400 invoice which seemed completely reasonable to me.
I received appointment reminders via text and email. The tester/employee showed up on time and I received a results phone call within 24 hours. I know I'll receive the emailed results within another work day, but they were able to call and give me the peace of mind sooner rather than later.
If you're looking for a quick and professional company, I'd highly recommend MARS Environmental.

Lead Testing FAQs

A: If your home or building was constructed before 1978, especially before 1960, there’s a high likelihood of lead-based paint. You should consider testing if:

  • You’re planning to renovate or remodel
  • There are young children or pregnant individuals present
  • You see chipping, peeling, or deteriorating paint
  • You’re planning to buy or rent an older home
  • Your property is near a high-risk area like an airport or major roadway
A: Lead-based paint in older homes and buildings is the most common source, but it can also come from drinking water, soil, imported items, and occupational exposure.
A: That depends on the inspection, but we’re always thorough and follow all state and federal regulations for our testing and remediation procedures. EPA & HUD guidelines require certain surfaces to be tested during inspection and require results to be at or below specific lead levels. These include floors (5 µg/ft²), interior windowsills (40 µg/ft²), window troughs (100 µg/ft²), exterior porches (40 µg/ft²), and exterior concrete (800 µg/ft²). Playground soil cannot exceed 400 µg/ft².
A: Yes, the Toxic Substances Control Act (TSCA), enacted to protect humans and the environment from toxic substances, mandates lead testing in any home that is occupied by the same child under 6 for 3+ hours/day, 6+ hours/week, or 60+ hours/year. Federal laws also require daycares be inspected and school drinking water tested.
A: Yes. M.A.R.S. uses one of the first HUD-approved XRF tube devices, which emits minimal radiation and does not damage surfaces or release lead from damaged paint. It’s fast, safe, and effective.

A: The most important thing you can do is get your home assessed and tested (especially if it was built before 1978) by a certified inspector. Other ways to reduce your risk include regularly dusting your home, removing shoes when you enter your home & changing your clothes if your occupation could expose you to lead, flushing your faucet before using it for food & drinks, and eating a healthy diet to reduce lead absorption.

A: This depends on the type of testing you want done, the size and age of your home, the distance from our office, and the number of potential exposure places.
  • Limited inspection: About 20 minutes
  • Full inspection: 1–2 hours
  • Multi-family or OSHA-compliant inspections may take multiple days
A: You’ll receive a detailed report explaining where testing occurred, who conducted it, what methods were used, and a breakdown of results. If lead is found, we’ll provide clear next steps for abatement (removal, enclosure, encapsulation, plumbing replacement, etc.) or mitigation.
A: Yes. We provide abatement recommendations tailored to your property. This could include removal, encapsulation, enclosure, or soil/plumbing remediation.
A: It’s important not to vacuum or dust before getting dust wipe sample testing. For XRF testing and paint testing, nothing needs to be done prior.

A: In October, 2024, the Biden-Harris administration passed stricter lead-based paint laws. This act established lead testing and removal requirements in certain facilities, including daycares, and declared that there’s no acceptable level of dust in clearance inspections.
