theory: set up collection points along the AT where hikers that use only ceramic filters can have their ceramic filters cleaned out by specially trained laboratory personnel. The contents of the clean-out can then be examined for Giardia Lambia and other microbes.
The ceramic filters will concentrate contaminants on the surface of the ceramic. The contaminants will be from a far ranging number of water sources along the trail. Hikers who participate would be instructed in advance to not open their filters on their own. Only lab personnel will open the filters.
The advantage of this approach is that the hikers are the ones doing the walking and collecting. The lab people who do the testing never need to go outside. That's what makes this approach so practical.
This test should tell you if there is Giardia Lambia in water sources along the trail, and how much of it there is. It won't tell you exactly where is is though.
