Here are morgellons fibres for comparison
(these are the lesions associated with chemtrail residue exposure)
Surely, if these fibres are being sprayed accross the skies on a repetitive basis it is going to find its way into the water supply. In fact, im pretty sure that we can be definite about that considering that fact that it evades all known water filtration systems.
