Testing For Lead In Soil

 Dirt PictureThe soil in the City of Minneapolis typically has high concentrations of lead due to the use of leaded gasoline before 1979. Residents interested in finding out the concentration of lead in their soil may submit samples to be analyzed.

Procedures for soil sampling: Collect one soil sample near the foundation of your house; placing it in a clean zip lock baggie. The sample size should be about 5 tablespoons from the top half inch of bare soil as this is the soil that is most accessible to children.

Collect a second sample from the yard; placing it in a separate zip lock baggie. Label the baggies "foundation," "yard," or "garden" when submitting them for analysis.

Sample Analysis: Samples will be analyzed using an x-ray fluorescence machine (XRF). Soil with over 100 parts per million (ppm) of lead is considered a hazard to children and should be covered with an appropriate material such as grass, rock, wood chips, concrete, etc. The results of the soil sampling will be accurate to plus or minus 50 ppm.

Sample Results: You can generally expect to receive your sample results within two weeks. This analysis is a free service provided by the City of Minneapolis. Private environmental laboratories can provide a more accurate soil result for a small fee.

Please mail your soil samples to:
