Proper sample preservation in temporary or remote applications is very difficult to achieve
without incurring costs to wire in AC power or to visit the sites frequently. Many watershed
assessment projects are prolonged or compromised because samples are not preserved properly.
Improperly preserved samples should be discarded, but may also end up in the lab resulting in
either wasted analytical time and cost, or faulty data.
