Easy and Reliable Test for Citizen Scientists


No labs required. Conduct on-site testing yourself.

Citizen Science Water Quality Monitoring


Everyone’s life is affected by water quality and access to safe water. In many countries, drinking and recreational waters are monitored by national, state and local governments. They are assisted by universities, research institutes and government-funded scientists.

However, these organizations do not have enough resources to monitor water quality in every river and watershed. Volunteer citizen scientists are a valuable asset for open collaboration with government agencies to help maintain biological, chemical and physical water quality standards.

Citizen Science Water Quality Tests


The CBT EC+TC MPN Kit and GEL EC CFU Kit are excellent tools for biological water quality testing by citizen scientists:


  • Lab-free and electricity-free
  • Easy to use with little training
  • Lets you self-test in the field and test waters not near a lab
  • Eliminates sending samples to a lab
  • More cost effective than lab testing
  • Generates comparable test results to gold standard testing methods

Surface and Recreational Waters


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

This is accomplished by a simple 1:10 dilution of 100 mL samples. CBT samples also can analyze wastewater samples with 1:100 dilutions or more.
