What should you do if a sample is contaminated during collection?

The most appropriate action when a sample is contaminated during collection is to discard the sample and collect a new one following proper procedures. This is essential because the integrity of the sample is crucial for obtaining accurate and reliable results. Contamination can introduce external substances that may compromise the validity of the analysis, leading to potentially inaccurate conclusions about the water quality.

By discarding the compromised sample, you ensure that any data obtained from the new sample reflects the true conditions of the water being tested. It is also necessary to strictly adhere to proper collection procedures during the new sampling to minimize the risk of contamination occurring again. This careful approach upholds the standards required for water sampling and analysis, ensuring that any findings are trustworthy and scientifically sound.
