What is field testing used for?

Field testing is primarily utilized for on-site testing that allows for immediate assessment of water quality. This method enables environmental health specialists and scientists to gather data directly at the source, providing rapid results that are crucial for making timely decisions about water safety and management. Conducting tests in the field minimizes the time delay associated with transporting samples back to a laboratory, allowing for quick identification of any potential issues that need to be addressed immediately.

In contrast, long-term assessments of water quality usually require comprehensive studies over extended periods, often involving laboratory analyses for detailed evaluation, which is not the primary focus of field testing. While compliance with EPA regulations is essential, such verification often entails a combination of both field and laboratory testing to ensure comprehensive and accurate results over time.
