Your diesel fuel will be tested for water and microbial contaminants...

fuel testing-diesel

Upon any tank integrity test a fuel sample will be taken for testing.

A simple scheduled 3 test will show water, fungal and bacterial contamination, moisture content and clarity. A comprehensive scheduled 3 can confirm the complete quality of the diesel. This will then indicate if it requires further attention.

Upon receiving your Tank Integrity Certificate you will also be provided with the complete breakdown on all fuel results taken from the fuel samples.
