How long do laboratories have to analyze water samples for coliform bacteria monitoring?

Laboratories have a maximum time of 30 hours to analyze water samples for the presence of coliform bacteria to ensure that the results are timely and reliable. This timeframe is critical because coliform bacteria can multiply if samples are not analyzed promptly, potentially leading to inaccurate results that could misrepresent the safety of the water supply. By adhering to this 30-hour limit, laboratory technicians can provide an accurate assessment of water quality and help maintain public health standards, enabling quick responses in case of contamination. This requirement aligns with regulatory guidelines intended to safeguard water safety and quality.
