Physical properties of soil & sediment

Physical properties of soil and sediment can be an integral part of environmental investigations. Typically, this information is used to decide mobility of contaminants and will impact remediation strategies.

The ALS difference

Knowing that our clients will need to assess the physical properties of soil and sediment as a part of their environmental investigation, ALS has decided to incorporate such testing as a standard part of our laboratory capabilities. The testing is performed within our environmental laboratories providing clients with a one-stop-shop.

Quality Testing. Quality Results.

All geotechnical analytical methods are performed by ALS ISO 17025 accredited laboratories. Where accreditation/certification is available specific methods will be accredited.

As with all methods performed by ALS, method development and validation follow the same protocol as for accredited methods guaranteeing the quality of results provided.
