numerical format. When results are below the applicable limits, they must be reported in the format. "<XX ma/L". where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L. Conversely, where fecal coliform results exceed the dilution upper limit, report the result as ">W.
