What is the reporting limit for all regulated VOC's?

• A. 0.5 mg/L
• B. 0.005 mg/L
• C. 0.00005 mg/L
• D. 0.0005 mg/L

Answer: (D)

The key idea is the lab’s reporting limit for regulated VOCs—the smallest concentration that must be reported with quantitative value. For VOCs in many drinking water programs, this reporting limit is 0.5 micrograms per liter, which is 0.0005 mg/L. In other words, labs report VOCs down to 0.0005 mg/L because that’s the practical lower quantifiable level for these analyses with standard methods. The other numbers represent much higher limits and aren’t used as the standard reporting threshold for regulated VOCs. Therefore, the reporting limit for all regulated VOCs is 0.0005 mg/L.
