The' unsampl eci' period assoCiated with a given composite analysis
con~ists of half the days in the unsampled periods inunediately prior
to or following that composite period.

tv - Cik:values for all days included in the analyzed composite period
~ are: set equal to Cia'
w
CD Method 2. - Category 1 chemical data, no daily specific conductance:

- Compute TDSa and Pi as in method 1.

- Compute solute concentrations for all days in the unsampled period

rosa
Cik = Pi s;- Sc

-,

where Sc'= specific conductance of composite sample including
. ' day k.

Uns,mpled periods are' associated with analyzed composites as in
method 1.

- Cik~values for all days included in the analyzed composite period
are'set equal to Cia'

Method 3, - Category 2 data:

- Cik,values for all days are set equal to Cia for the associated
composite.

Method 4, - Category 3 data with da4ly specific conductance:

- Compute rosa of the instantaneous sample (a) using measured solute
~oncentrations (Cia)'

- Compute mass fractions (Pi) for the six solutes.

_ Cia
Pi - TDSa

- Com.ute solute concentrations (Cik) for all days (including the
day of sample).
