Worried about lead contamination and health hazards?
Adviro provides lead testing for screenings of potentially contaminated dust, soil and/or water:
Dust wipe sampling — We test dust for lead hazard contamination from questionable renovation/demolition work, deterioration of building materials, or a lead-based paint abatement clearance. Testing can provide family safety before moving into your home post renovation, or simply moving in an old-style Victorian home, having alleviated any lead-hazard concerns.
Soil sampling — We test your site’s surrounding soil for lead hazard contamination due to previous or current renovation/demolition work. Testing can provide peace of mind for a vegetable garden or children’s play area.
Water sampling — Our testing for lead in residential drinking water is recommended for pre-1978 homes with original water piping. These pipes can contain lead in the soldering which our first draw water testing method analyzes. With passing results, you can confidently drink your tap water knowing it’s lead-free.
Lead Testing and Reporting Process
When contacting us, we’ll discuss your needs and explain how we can help. Additionally, we’ll include an itemized proposal of our lead services.
Once you choose to work with Adviro by signing the proposal, we’ll immediately contact you to schedule your appointment.
Our certified lead technician will visit your property for environmental sampling, material identification and documenting the process. They will take non-invasive wipe samples, soil samples, and water samples to identify the lead content. These samples will be prepared for independent laboratory analysis. Plus, we use X-ray fluorescence (XRF) technology, providing on-site results for lead based paint.
Once all results are gathered, we’ll deliver clear, concise and detailed reports with pictures, diagrams, certifications and documentation compliant for regulatory agencies. The detailed information provided in our reports delivers and shows due diligence for compliance as well as any possible future litigation.
Please review your report.
Our consultants/technicians are available or will contact you for further review of any specific details related to your project. At this point, with the specific details, we can consult regarding potential strategies for your next course of action.

Lead Water Testing for Child Care Centers in California (as of 2026) – Assembly Bill 2370 (AB 2370)
Lead exposure continues to be one of the most serious environmental risks for young children. According to the Environmental Protection Agency, drinking water can contribute up to 20% of a child’s total exposure to lead—a neurotoxin that can affect brain development, learning ability, and behavior.
LEAD FAQS
What is lead?
According to the EPA, lead is a naturally occurring element found in small amounts in the earth’s crust. While it has some beneficial uses, it can be toxic to humans and animals, causing health effects.
Where is lead found?
The EPA says lead can be found in all parts of our environment – the air, the soil, the water, and even inside our homes. Much of our exposure comes from human activities including the use of fossil fuels, past use of leaded gasoline, some types of industrial facilities and past use of lead-based paint in homes. Lead and lead compounds have been used in a wide variety of products found in and around our homes, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition and cosmetics.
Lead may enter the environment from these past and current uses. Lead can also be emitted into the environment from industrial sources and contaminated sites, such as former lead smelters. While natural levels of lead in soil range between 50 and 400 parts per million, mining, smelting and refining activities have resulted in substantial increases in lead levels in the environment, especially near mining and smelting sites.
When lead is released to the air from industrial sources or spark-ignition engine aircraft, it may travel long distances before settling to the ground, where it usually sticks to soil particles. Lead may move from soil into ground water depending on the type of lead compound and the characteristics of the soil.
Federal and state regulatory standards have helped to reduce the amount of lead in air, drinking water, soil, consumer products, food, and occupational settings.
When was lead paint banned?
Lead-based paint was banned for consumer use in 1978 by the federal government — and some states banned it even earlier. Today, lead-based paint is still present in millions of homes, typically under layers of newer paint. If the paint is in good shape, the lead-based paint may not be a problem, but it is always good to check it out with testing.
What is the difference between a lead survey and lead screening?
A lead survey is typically a survey of potentially hazardous materials that may contain lead in a home. It is often done before demolition or renovation for health and safety reasons.
A lead screening is a more comprehensive testing of everything from the air to the water inside a home as well as the materials that the building is made of. It is typically required when the purpose is primarily to uncover health hazards.
When you come to an environmental testing company like Adviro, we can help you determine which type ot lead testing is best for you.
What does lead paint look like?
Two physical clues may indicate that you have lead-based paint. The first one is “alligatoring” which is when the paint looks like the scales pattern of an alligator, which happens when the paint starts to crack and wrinkle. The second indication you have lead is the appearance of chalky residue when the paint rubs off.
Who is at risk for lead poisoning?
Children
Lead is particularly dangerous to children because their growing bodies absorb more lead than adults do and their brains and nervous systems are more sensitive to the damaging effects of lead. Babies and young children can also be more highly exposed to lead because they often put their hands and other objects that can have lead from dust or soil on them into their mouths. Children may also be exposed to lead by eating and drinking food or water containing lead or from dishes or glasses that contain lead, inhaling lead dust from lead-based paint or lead-contaminated soil or from playing with toys with lead-based paint.
Adults, Including Pregnant Women
Adults may be exposed to lead by eating and drinking food or water containing lead or from dishes or glasses that contain lead. They may also breath lead dust by spending time in areas where lead-based paint is deteriorating, and during renovation or repair work that disturbs painted surfaces in older homes and buildings. Working in a job or engaging in hobbies where lead is used, such as making stained glass, can increase exposure as can certain folk remedies containing lead. A pregnant woman’s exposure to lead from these sources is of particular concern because it can result in exposure to her developing baby.

What are the health effects of Lead?
Lead can affect almost every organ and system in your body. Children six years old and younger are most susceptible to its effects.
For children, even low levels of lead in the blood can result in:
Behavior and learning problems
Lower IQ and Hyperactivity
Slowed growth
Hearing Problems
Anemia
In rare cases, ingestion of lead can cause seizures, coma and even death.
Lead can accumulate in our bodies over time. During a pregnancy, lead is released from the mother’s bones and can pass from the mother exposing the fetus or the breastfeeding infant to lead. This can result in serious health issues such as premature birth, learning and behavorial problems, the possibility of a miscarriage and more.
Adults exposed to lead can suffer from: Cardiovascular effects, increased blood pressure and incidence of hypertension, decreased kidney function, and reproductive problems (in both men and women).
How many homes still contain lead-based paint?
The Department of Housing and Urban Development’s (HUD) National Survey of Lead and Allergens in Housing estimated that 38 million permanently occupied housing units (40% of all housing units) in the United States contain some lead-based paint that was applied before the residential use of lead-based paint was banned in 1978.
“Housing units” include single-family homes, manufactured housing, and multi-unit dwellings like apartments. Vacant housing, group quarters (e.g., prisons, hospitals, and dormitories), hotels, motels, military bases, and housing where children are not permitted to live (e.g., housing designated exclusively for the elderly and those with zero-bedroom units) are not included in this number. More information on these statistics is available from HUD.
How can I tell if my home contains lead-based paint?
According to the EPA, the older your home, the more likely it contains lead-based paint. For example, 87% of homes built before 1940 have some lead-based paint, while 24% of homes built between 1960 and 1978 have some lead-based paint. Lead-based paint may be present in private single-family homes or apartments, government-assisted, or public housing, and in urban, suburban, or rural settings. Assume your home contains lead-based paint and take the appropriate precautions. In pre-1978 homes and buildings, this is the simplest and safest approach.
What should I do if I think my home has lead paint or lead fixtures?
Hire a certified professional to check for lead-based paint. A certified lead-based paint inspector or risk assessor can conduct an inspection to determine whether your home or a portion of your home has lead-based paint and where it is located. This will tell you the areas in your home where lead-safe work practices should be used for renovation, repair, or painting jobs. A certified risk assessor can conduct a risk assessment telling you whether your home currently has any lead hazards from lead in paint, dust, or soil. The risk assessor can also tell you what actions to take to address any hazards. For help finding a certified risk assessor or inspector, call the National Lead Information Center at 1-800-424-LEAD (5323).
