In addition to drinking water quality testing, our customers also use the Aquagenx CBT EC+TC Kit for water quality testing of streams, rivers, marine/sea waters and even waste water. 

The CBT EC+TC MPN Kit is easily adapted for more contaminated waters with higher concentrations of bacteria and for waters with higher allowable limits of bacteria.

This is accomplished by diluting CBT samples using 10 mL samples and 90 mL of diluent.

Any dilution beyond 1:100 that still gives all positive (blue) compartments in the Aquagenx Compartment Bag means the water is very high risk and is not suitable for drinking without treatment to eliminate the presence of E. coli, or to reduce E. coli to very low numbers.
