How do you convince regulators that sampling methods are appropriate
How do you convince state regulators that low flow and no flow sampling methods are appropriate?
Provide a number of peer-reviewed and published studies that have been done on these different methodologies. If you are trying to get them to accept the idea of low flow purging and sampling which has been very well documented and very well studied over nearly 20 years, there are plenty of published peer-review studies that support its use for the widest range of analytes, just about anything you can imagine, inorganics, organics, radionuclides, biologicals, and others. If you are talking about passive and no-purge sampling, it could be a little bit trickier. There are fewer published and peer-reviewed studies on this topic and the comparisons in those don’t always correlate. But, use the scientific literature as a means of convincing the regulators. Also, use the ASTM standards. For example, ASTM standard D6771 on low flow purging and sampling is in essence a consensus standard. A law signed back in 1993 states that federal regulatory agencies are supposed to adopt consensus standards where they exist. So use ASTM standards, use published literature, and if you have trouble locating either of those QED is happy to help as resource.
