Chemical & Environmental Testing
 
COD (Chemical Oxygen Demand) Test
 
Provision of tests required for environmental baseline study and the on-going monitoring of environmental impact during site activities
 
FT Laboratories team of chemists provides chemical analysis for a wide range of materials. All tests are carried out to the relevant ASTM (American Society for Testing and materials), APHA (American Public Health Association), and BS (British Standard) standards.

FT’s environmental monitoring team is able to monitor environmental parameters as defined in the EM&A Manual.
Benefits of using FT's service
 
. Chemical testing compliments our other services, all testing can be carried out by one laboratory.
. FT is continually expanding the number of chemical and environmental tests performed.
