I think BLAST stated that you would have to EAT seven of the older Nalgene bottles a day for a year to reach the levels of BPA that was used in these studies.It is a shame that Nalgene and other companies were singled out on this.The older Nalgenes would bounce off rocks /pavement. The newer ones not so much.Frozen solid filled with water,older nalgenes were good to go.I have even used a Nalgene as a wheel chock on a hill for a full size truck.Hmmmm any one have the old style Nalgenes they want to get rid of......
