I understand that Water Bottles expire due only to the fact that the plastic can degrade over time and leach into the water making the water's taste not as desirable as the manufacturer might intend.
Does anyone happen to know the degradation rate/expiration for #4 LDPE? I'm using a plastic water storage vessel for long term water storage in m emergency preparedness supplies and would like to make sure the plastic doesn't leach. Please let me know! Thanks!
