So what do the numbers mean, you ask. Following is a list of pertinent information.
- The units for measurement are MPNs (Most Probable Number) per 100ml
- Ent -> Enterococcus
- * next to the site name means the site is a freshwater site
- # At marine sites we only test for Enterococcus.
- N/S means there was no sample.
- A ! next to the same means there was an issue with the sample and an associated note will be included at the bottom of the page
