Soil Screening

A soilSHOP soil screener wearing gloves while showing soil sample.

soilSHOP events are free and generally operate on a first-come, first-served basis. Residents can bring in several samples of soil from their yards and provide information about their soil sample on a Log-In Form. Event staff will screen soil on site and provide same-day results to event participants.

Trained technicians usually conduct soil screening at soilSHOP events. Soil screening volunteers are asked to:

  • become familiar with the soilSHOP process and soil screening guidance,
  • know how to use x-ray fluorescence (XRF) instruments,
  • screen soil samples at the event, and
  • wear personal protective equipment.
