How often to Acid Wash sampler hoses?
I was asked how often MUST you acid wash sampler hoses used to sample for metals for an NPDES Stormwater program. Can't say that I know any definitive answer based on Standard Methods or EPA documents. I do know that it is "painful" to remove and reinstall sampler hoses set up in manholes for stormwater sampling. Anyone willing to share their current practices on the matter? Thanks, Keith
