Land's Formula Individual Well UCL Calculation
Land's Formula Individual Well UCL Calculation
Description:
This method uses the same formulas as the Land's Formula UCL calculated from background. Instead of a compliance-background comparison, this method calculates the UCL for all sampling locations based on the samples collected from only those locations (for a single parameter). No comparisons so there is no determination of statistical significance. This method is recommended for naturally log-transformed data. UCL can be calculated upward or downward at the 95% confidence level or two-tailed at the 90% confidence level.
This method is for scenarios where only a UCL value is desired without an assessment of contamination.
