Trace Metals results pending
Samples are analyzed in order of arrival with priority
given to analyses with shorter holding times. Trace metals have
the longest holding time (6 months), are performed by complex instrumentation
analyses, and have no analyst's time solely dedicated to their
analysis due to current staff workload. The results for trace metals
will most often be the last entered. |
Bacteria Monitoring
As of June 2002, a new test method was used to evaluate bacteria in the untreated
waters of the reservoir. The IDEXX “Quantitray MPN Method” measures Escherichia
coli colony forming units per volume; whereas the “MFC Membrane Filter
Method” measures fecal coliforms colony forming units per volume (using an Escherichia
coli Medium for growth). The methods are relatively comparable in numbers,
however the Quantitray method provides a lower detection limit. |
