Frequent Questions

How many liters should I collect for my Crypto samples?

Systems must analyze at least a 10 liter sample for Cryptosporidium, or a packed pellet volume of at least 2 mL as generated by Method 1623.  Systems unable to process a 10 liter sample (due to high turbidity) must analyze as much sample volume as can be filtered by two filters approved by EPA for Method 1623 (141.704 (a)(1)).
