      The LOAD keyword is used to compute stream loadings for selected
 parameters.  A flow parameter must be present within the retrieved
 sample in order to perform the loading calculation for other parameters
 within the same sample.  LOAD applies to each parameter (P=) keyword it
 follows, and may be specified as many times as desired within a
 retrieval request.  The following formula is used when calculating
 loadings.

                                PV * FV * PC
                     LOADING = --------------
                                     FC



 Where:

       PV = parameter value (concentration)
       FV = flow value
       PC = parameter unit conversion factor; this value
            is used to convert the stored units for the
            concerned parameter to the loading units,
            according to the following table -

            Stored Unit                    Loading Unit
            -----------                    ------------
            milligrams/liter (mg/l)        lbs/day
            micrograms/liter (ug/l)        lbs/day
            pico curies/liter (pc/l)       pc/day
            number/100 milliliter          number/day

       FC = flow unit conversion factor; this value is
            used to convert the flow value units to cubic
            feet per second (CFS)
