How long do samples need to be analyzed after collection?

Samples collected for testing in the context of heating oil tanks typically need to be analyzed within 14 days to ensure the accuracy and reliability of the results. This timeframe allows for the preservation of the sample’s integrity, as various chemical and biological processes can alter the sample if it is not analyzed promptly. Analyzing the samples within this period helps in obtaining relevant data for assessing the condition of the heating oil, determining contamination levels, or planning further actions such as remediation. The 14-day window is generally accepted in industry standards to balance timeliness and practical laboratory capabilities.
