predominately pool-riffle character. The results seem fairly
reasonable. The reach with the most c han ne I -con t r o I character
should probably be the Forest Grove to LaVista; the fact that A
exceeds 1.0 and B is negative for this reach indicates that the
river may flow abnormally fast through this stretch. The reach
With the most pool-riffle character would certainly be Petty Or
to Forest Grove, which includes Alberton Gorge.
The values for A and B were rounded off to the common fractions
which are shown in the "Used" columns. The determination of
travel-times at other flows was done by the following procedure
1. divide the river from below Milltown to above Thompson
Falls into reaches;
2. determine the flow at USGS gauge below Missoula;
3. estimate the flow for the other reaches;
4. calculate V and V for each reach followed by
estimates of V using Tne equations given above;
m
5. using the estimates of V calculate the travel time for
each reach and keep a cumulative total.

For the synoptic sampling runs the "Hour" column in the above
table was used to determine when to sample at each station,
"window" of + or - 5% of the cumulative hour was allowed,
example, at 3000 cfs the sampling schedule allowed for the
station at Superior to be sampled anytime from 38.1 to 42.1
hours after the start of the sampling run below Milltown.
Although an attempt was being made to track a slug of water,
actuality the slug disperses greatly as it moves downstream
This was noted in the dye-study and justifies the + or - 5%

SAMPLE PRESERVATION
Complete and unequivocal preservation of samples, either domestic sewage, industrial wastes, or
natural waters, is a practical impossibility. Regardless of the nature of the sample, complete stability
for every constituent can never be achieved. At best, preservation techniques can only retard the
chemical and biological changes that inevitably continue after the sample is removed from the parent
source. The changes that take place in a sample are either chemical or biological. In the former case,
certain changes occur in the chemical structure of the constituents that are a function of physical
cc editions. Metal cations may precipitate as hydroxides or form complexes with other constituents;
cations or anions may change valence states under certain reducing or oxidizing conditions; other
constituents may dissolve or volatilize with the passage of time. Metal cations may also adsorb onto
surfaces (glass, plastic, quartz, etc.), such as, iron and lead. Biological changes taking place in a
sample may change the valence of an element or a radical to a different valence. Soluble constituents
may be converted to organically bound materials in cell structures, or cell lysis may result in release
of cellular material into solution. The well known nitrogen and phosphorus cycles are examples of
biological influence on sample composition. Therefore, as a general rule, it is best to analyze the
samples as soon as possible after collection. This is especially true when the analyte concentration is
expected to be in the low ug/1 range.
Methods of preservation are relatively Umited and are intended generally to (1) retard biological
action, (2) retard hydrolysis of chemical compounds and complexes, (3) reduce volatility of
constituents, and (4) reduce absorption effects. Preservation methods are generally limited to pH
control, chemical addition, refrigeration, and freezing.
The recommended preservative for various constituents is given in Table 1 . These choices are based
on the accompanying references and on information supplied by various Quality Assurance
Coordinators. As more data become available, these recommended holding times will be adjusted to
reflect new information. Other information provided in the table is an estimation of the volume of
sample required for the analysis, the suggested type of container, and the maximum recommended
holding times for samples properly preserved.

1. More specific instructions for preservation and sampling are found with each procedure as
detailed in this manual. A general discussion on sampling waicr and mdustrial wastewater may
be found in ASTM, Part 31, p. 72-82 (1976) Method D-3370.
2. Plastic (?) or Glass (G). For metals, polyethylene with a polypropylene cap (no liner) is
preferred.
3. Sample preservation should be performed immediately upon simple collection. For
composite samples each aliquot should be preserved at i lie time ot collection. When use of
an automated sampler makes it impossible to preserve each aliquot, then samples may be
preserved by maintaining at 4°C until compositing and sample splitting is completed.
4. When any sample is to be shipped by common carrier or sent through the United States
Mails, it must comply with the Department of Transportation Hazardous Materials
Regulations (49 CFR Part 172). The person offering such material for transportation is
responsible for ensuring such compliance. For the preservation requirements of Fable 1 ,
the Office of Hazardous Materials, Materials Transportation Bureau, Department of
Transportation has determined that the Hazardous Materials Regulations do not apj)ly to
the following materials: Hydrochloric acid (HCl) in water solutions at concentrations of
0.04% by weight or less (pH about 1 .96 or greater); Nitric acid ( HNO3) in water solutions at
concentrations of 0. 1 5% by weight or less (pH about 1 .62 or greater); Sulfuric acid ( 1 1 2S04)
in water solutions at concentrations of 0.35% by weight or less (pH about l.l.'j or greater);
Sodium hydroxide (NaOH) in water solutions at concentrations of 0.080% by weight or
less (pH about 12.30 or less).
5. Samples should be analyzed as soon as possible after collection. The times listed are the
maximum times that samples may be held before analysis and still considered valid.
Samples may be held for longer periods only if the permittee, or monitoring laboratory,
has data on file to show that the specific types of sample under study are stable for the
longer time, and has received a variance from the Regional Administrator. Some samples
may not be stable for the maximum time period given in the table. A permittee, or
monitoring laboratory, is obligated to hold the sample for a shorter time if knowledge
exists to show this is necessary to maintain sample stability.
6. Should only be used in the presence of residual chlorine.
