| Sample
Number N/A Bacterial Identification, Counts, & Information Time N/A |
|
| Nutrient plate count | 1370 colonies per milliliter |
| Bacterial Identification | Commamonas testosteroni |
| ATP count | 1.8 million cells per milliliter |
| Sulfate Reducing Bacteria | Positive |
| Anaerobic Growth | 45% |
| Microscopic analysis | Massive decaying bacterial debris, large Gallionella presence |
| Notes | Iron 6.5 ppm, TDS 412 ppm, pH 7.2, phosphates .2 ppm |
| Coliform Bacterial | Negative |
| Fecal Coliform | Negative |
Interpretation
Nine separate observations are used to identify bacterial problems, 1
& 2. Nutrient plate which includes identification and colony counts
of aerobic bacteria, 3. ATP which is a separate count of all living organisms
in water, 4. Sulfate Reducing Bacteria which is a specific ID and severity,
5. Anaerobic Growth which includes a subjective percentage of all bacteria,
6. Microscopic Analysis which is a filtered sample that includes ID of
any iron bacteria present along with any iron oxides from decaying organisms,
and 7. Notes which allows some other points of chemical interest.
