A short primer on plastics:
Many single compound plastics are very inert and do not add detectable amounts of contaminants to water: polyethylene (PEX and rotomolded tanks) and rigid PVC (used in home piping).
Other plastcs either release a bit of the compound from which they are made- polycarbonate releases a little BPA or flexible PVC which blends a bit of phthalates with the PVC to make it flexible and a little of the phthalate gets released.
If a plastic releases anything into the water, I wouldn't use it.
