Number of Samples Exceeded
From the help published with Drinking Water Watch 3.5, reproduced as delivered.
The number of samples exceeded is the number of samples beyond or outside of the level set in the Facility Analyte Level (FANL) for this analyte and water system facility (WSF). For instance if the level set in a FANL is a minimum, this field records the number of samples below the minimum level. Likewise if the level set in the FANL is a maximum, this field records the number of samples above the maximum level.
