What is the reporting limit for all regulated volatile organic compounds (VOCs)?

0.001 mg/L
0.0005 mg/L
0.01 mg/L
0.1 mg/L

The correct answer is: 0.0005 mg/L

The reporting limit for regulated volatile organic compounds (VOCs) is commonly set at 0.0005 mg/L. This limit is important because it signifies the minimum concentration at which these compounds can be reliably detected and quantified in water samples. Regulated VOCs include a variety of chemicals that can have significant health effects if present in drinking water, so stringent standards are enforced to protect public health. Setting the reporting limit at this level ensures that even trace amounts of hazardous substances can be monitored, allowing for adequate risk assessment and management of water quality. This practice helps in identifying and addressing contamination issues, ensuring safe drinking water supply. Understanding the reporting limits for VOCs is crucial for compliance with regulatory standards and for the effective monitoring of water resources.
