Soil Analysis

  • Sludge Sites
  • Sandblasting Sites

Sludge disposal sites must have their soil analyzed for various parameters, so loading rates can be determined and use/non-use criteria can be evaluated. Typically, fields are to be tested every three years. Davy Laboratories provides the analytical results, along with crop planting guidelines and interpretation of soil characteristics (in relation to the nutrients found). Over time, this information becomes more valuable when determining nitrogen, phosphorus, and potassium loading rates.

Monitoring sand from sandblasting operations, along with analyzing soil samples collected downwind of a site, is often required for paint-removal projects or demolition.
