And on background: Under EPA's Lead and Copper Rule, compliance monitoring for lead is specific to "total lead", which includes all forms of lead potentially in the sample (dissolved and particulate, i.e. undissolved scale.) Tests that only evaluate dissolved lead may not accurately reflect total lead present. Additional factors are sensitivity, precision (reproducibility) and accuracy.

I work in the research department at the CBS Evening News. I'm hoping someone can help me with the following question: On average, how long would it take for a labratory to process the results of a water sample? Is it accurate to say that it can take multiple days for a test to be processed? Thanks in advance for your help. My deadline is 5:30 EST. Best, Sierra Club v.
