Avoiding Bisphenol A leach in oboard water tanks?

[pskhaat]

Are you concerned with BPA leaching from plastic water tanks (either fixed or portable)?

Seems like a bigger risk with tanks than Nalgenes

I am concerned with any plastic used in potable water tanks. There is an approved type of PVC, but I prefer welded white poly such as the material used in many RV tanks.

Another reason I only drink beer.

In the reading that I done on the topic, the only polymer mentioned has been polycarbonate. Most drinking water containers used in overlanding are made from polyethylene (PE), which I've not seen mentioned as having BPA used in it's manufacture. The typical Nalgene bottle of the past is made from PE.
