The United States Environmental Protection Agency (EPA) has lowered the screening level for lead in soil from 400 parts per million (ppm) to 100 ppm. This means that the agency now considers soil with lead levels at or above 100 ppm to be a potential health hazard.

Why Did the EPA Lower the Screening Level?

The EPA lowered the screening level for lead in soil based on new scientific evidence that shows that even low levels of lead can have harmful effects on children's health. Lead exposure can cause a range of health problems, including:

* Developmental delays

* Learning disabilities

* Attention deficit hyperactivity disorder (ADHD)

* Behavior problems

* Hearing loss

* Kidney damage

* Brain damage

What Does This Mean for Households Across the US?

The EPA's new screening level for lead in soil means that millions of homeowners across the US may have soil that is contaminated with lead. If you are concerned about the lead levels in your soil, you can have it tested by a qualified environmental professional.

What Can You Do if Your Soil is Contaminated with Lead?

If your soil is contaminated with lead, there are a number of things you can do to reduce your exposure to it. These include:

* Covering bare soil with grass or mulch

* Washing your hands frequently, especially after gardening or playing in the soil

* Cleaning your home regularly, especially areas where children play

* Using a water filter that removes lead

* Eating a healthy diet, including foods that are rich in iron and calcium

The EPA's new screening level for lead in soil is a significant change that will have a major impact on public health. By lowering the screening level, the EPA is sending a clear message that even low levels of lead can be harmful to children's health.
