What types of parameters are included in the EPA 500 Series of test methods?

The EPA 500 Series of test methods specifically focuses on the analysis of organic compounds in drinking water. This series includes methods for measuring various volatile organic compounds (VOCs) and some semi-volatile organic compounds, which are of significant concern due to their potential adverse health effects when present in drinking water supplies.

The inclusion of these compounds is crucial for ensuring the safety and quality of drinking water, as many organic contaminants can come from industrial discharges, agricultural runoff, and domestic sources. Being part of federal guidelines, the methods in the 500 Series provide the protocols needed to reliably detect and quantify these compounds, supporting regulatory compliance and public health protection.

While the other choices refer to important aspects of water testing, they do not fall under the specific focus of the EPA 500 Series. The EPA has other series and methods that address those parameters, but the essence of the 500 Series is its emphasis on organic contaminants relevant to drinking water.
