Shocking New Study Reveals That 25% of U.S. Yards Have Unsafe Levels of Lead

Nearly 40% of households may exceed safety recommendations due to multiple sources of lead exposure. Nationally, applying standard remediation techniques to address this could exceed costs of $1 trillion.
A new study reveals that approximately one in four U.S. households have soil that contains lead levels exceeding the U.S. Environmental Protection Agency’s updated screening threshold of 200 parts per million (ppm), a reduction from the previous limit of 400 ppm. Additionally, for households facing exposure from multiple sources, the EPA has further reduced the guideline to 100 ppm; the study found that nearly 40% of households surpass this stricter level.
