Interpretation
Inorganics/water chemistry
All of the water constituents are considered to determine water chemistry
problems due to mineral precipitate, corrosion, etc. If a customer does
not have any idea of whats causing well problems, this can look
at both the mineral and biological aspects.
Organics
Five 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. Microscopic Analysis which is a filtered sample that includes
ID of any iron bacteria present along with any iron oxides from decaying
organisms, and 5. Notes which allows some other points of chemical interest.
