March 22 has been designated World Water Day by the United Nations (UN) to draw attention to the millions of people around the world who still do not have access to clean, safe water. The UN launched the long-running campaign in 1993 to support their Sustainable Development Goals of safe access to clean water for everyone by the year 2030. 

We get asked a lot of questions – as I am sure you do during the course of your day. “What is the detection limit of Colilert?” (1 organism/100mL) “Why does Legiolert only test for Legionella pneumophila?” (Because it causes 97% of Legionnaires’ disease cases.) “Where are your tests manufactured?”  (proudly developed and manufactured in Westbrook, Maine, USA.)

But the one question that we are most familiar with is ‘what’s the difference between the Most Probable Number (MPN) and a Colony Forming Unit (CFU)?’
