What can result from improper sample handling?

Improper sample handling can lead to compromised integrity and contamination of samples, ultimately resulting in invalid test results. If samples are not collected, stored, or transported correctly, this can introduce variables that skew the data and lead to conclusions that do not accurately reflect the true conditions of the environment or system being tested. For example, exposure to light, temperature extremes, or even cross-contamination from other substances can alter the properties of the sample, leading to inaccurate readings during analysis.

In this context, invalid test results can affect decision-making processes, regulatory compliance, and even public health and safety, making proper sample handling crucial in the field. The accuracy of the data obtained from a sample is vital for maintaining the quality and reliability of procedures in water quality testing and other scientific analyses.
