What is the reporting limit (RL)?
The laboratory reporting limit is the lowest concentration of a specific chemical that the laboratory can accurately measure, within specified limits of precision and accuracy. Most reporting limits for VOCs are of 1 part per billion (0.5 ug/l) or 500 parts per trillion. In the case of EDB, the reporting limit is 1/100 part per billion (0.01 ug/l) or 10 parts per trillion. Q: What does ug/l mean? A: The term ug/l refers to micrograms per liter and is a measure of a concentration. It is more commonly known as parts per billion (ppb). One part per billion equals 1 part in 1,000,000,000 parts. An analogy for parts per billion is looking for one drop in 22,000 gallons (similar to one drop in an Olympic-sized swimming pool).
