WebSample processing time 1 hour. Recommended sample volumes to be diluted to 100 mL and filtered, according to water type, are: 100 mL lakes, reservoirs, wells, springs; 50 mL … WebThe method has a 10 ppb detection level listed, but it is such an old method that the validation data are difficult to track down, but ostensibly came from Hach originally. Labs using the method in NJ are unable to get down to a 10 ppb MDL, but changing that to 20 ppb (achievable) is a technical change, so we need data.
