When would you check "special sample" on the microbiological sample form?

Checking "special sample" on the microbiological sample form is necessary when collecting samples for non-compliance reasons. This label is used to indicate that the sample is being taken under circumstances that differ from routine compliance sampling. Non-compliance reasons might include situations where there is an indication of contamination, unusual events, or specific concerns raised about water quality that require closer examination. By marking the sample as "special," it clarifies to the laboratory and regulatory bodies that this sample should be analyzed with consideration of the context in which it was collected, ensuring appropriate handling and scrutiny. This designation helps in tracking the effectiveness of corrective measures or responses to contamination reports, facilitating a thorough investigation into water quality issues.
