Bridger Analytical Lab, INC. [BAL] is a water testing laboratory in Bozeman, Montana. Our lab focuses on microbiological and inorganic analysis. The lab offers complete water testing support.

The most common tests are Bacteria ( total & fecal coliform) and Nitrates. Examples of other tests that are routinely performed in
suspected areas are conductivity, pH, hardness, fluoride, chloride, phosphate, and sulfate.

For sample bottles and instructions, call the lab or stop in to pickup the appropriate containers with directions for appropriate sample collection.

Our hours are 8:30 AM to 5:00 PM, Monday thru Friday. We are located in Four Corners, directly behind Pure Water Technologies.


Currently MT State Certified for: Bacteria & Nitrates, Conductivity, pH, Chloride, Fluoride, & Sulfate

What Services does BAL offer?

Established in 2007, Bridger Analytical Lab, Inc. provides independent, quality controlled confidential analytical services in public and domestic water testing. Our Bozeman, Montana laboratory specializes in inorganic and microbiological analysis of water. The most common test are Bacteria (total & fecal Coliform) and Nitrates. The lab offers complete water testing support.

Certification: Bridger Analytical Lab, Inc. is certified by the State of Montana's Environmental Laboratory to analyze samples from public drinking water systems. The certification applies to the analysis of a variety of parameters. Our analysts are certified by the Montana Department of Health and Human Services to provide analysis of Microbiological contaminants. Our staff can recommend necessary testing for your particular well or drinking water, help you interpret the results of the testing, and assist you in finding solutions to correct problems indenitified through our test results.

All Public drinking water results are reported to the State via EDI as per State Regulations.

Inorganic


Nitrate+Nitrite
Can be naturally occurring, but often is associated with contamination from septic systems, animal corrals or feedlots, or runoff from fertilizers. The EPA has established a max contaminant level for Nitrate of 10 mg/L & for Nitrite of 1mg/L.

Conductivity
Provides an estimate of the amount of minerals dissolved in the water - high conductivity indicates a large amount of dissolved minerals, which could adversely affect the quality of the water.

Fluoride
Concentrations greater than 2.0 mg/L can produce florosis (Mottling of the teeth) in children under the age of nine. EPA has set a drinking water limit for fluoride at 4mg/L.

PH
Indicates how acidic or basic the water is EPA recommends drinking water have a pH between 6.5 to 8.5 units.

Sulfate
Concentrations above 250mg/L can have a laxative effect for those not used to drinking the water.

Microbiological


Total Coliform Bacteria/E. coli (fecal coliform)
Are naturally present in the environment and are used as a indicator that other, possibly harmful bacteria may also be present. E. coli bacteria are an indication of human or animal fecal contamination.

IRB (Iron Related Bacteria)
More common than sulfur bacteria because iron is abundant in ground water. Iron levels above 0.3 mg/L may support the growth of iron bacteria, which may form a reddish brown or yellow slime that can coat well screens and clog plumbing. These bacteria may cause an odor simlar to fuel oil, cucumbers or sewage.

SRB (Sulfate Reducing Bacteria)
Break down sulfur compounds producing hydrogen sulfide gas in the process. Hydrogen sulfide gas is foul smelling and highly corrosive. The most obvious sign of a sulfur bacteria problem is the distinctive "rotten egg" odor of hydrogen sulfide gas, blackening of water or dark slime coating the inside of toilet tank may also indicate a sulfur bacteria problem.

Slyme Forming Bacteria
Is the name given to bacteria that are able to produce copious amounts of slime. This slime can contribute to plugging, loss in efficiency of heat exchangers, clouding, taste and odor problems.

HPC (Heterotrophic Plate Count)
A procedure used to estimate the number of live heterotrophic bacteria that are present in a water sample. EPA guidelines recommend that HPC levels should not exceed 500 bacteria / ml. Results exceeding 500 bacteria / ml are an indicator of deteriorating water quality.
