Odor and Taste Contaminants(Geosmin and 2-Methylisoborneol 2-MIB)

Geosmin and 2-MIB (methyl isoborneol) are the two most commonly tested taste and odor compounds in drinking water. These compounds are responsible for the earthy, musty odor and taste in water and are caused by algal blooms.  AEL can provide routine testing for these compounds in response to customer complaints.  AEL has been performing this analysis for municipalities across the United States for over 11 years.  We are close to receiving samples from all lower 48 states.  Some waters have breakouts of geosmin/2-MIB in the spring and summer time, while other locations around the United States see a spike during winter months. Several techniques are being used by municipalities to combat the two compounds.  AEL provides accurate quick results so adjustments can be made to your system in a timely manner.  If you are trying to decide which carbon is best for you, we can help with that too.

AEL performs analysis for Food & Beverage industry as well.  We have performed taste and odor testing for the USDA.  We can test your product as well to see what impact geosmin / 2-MIB may be having.

We follow SM 6040D SPME by GCMS
