Beginning February 1, 2019, instead of using the acronym “ND” for None Detected at or above the reporting limit, we are going to use the ‘less than’ symbol. Here’s what we mean. (Follow the red text):
|Found||RptLmt||Units||Vol (L)||Time (min)||Found||RptLmt||Units|
|Found||RptLmt||Units||Vol (L)||Time (min)||Found||Units|
Why make the change?
Customers have called us believing the RptLmt column in the Concentration section of the report is the regulatory limit. By only showing the reporting limit when the result is non-detectable, fewer customers will be alarmed when the result is detectable.
Here’s an example of how the reports will look.
