Chemical Contamination of Water in West Virginia

Apparently no treatment regimen exists. Time and dilution to safe(er) levels are the order of the day.

Chemical contamination obviously presents a problem. Living in an area rife with old mines I'v always been concerned when pulling water out of creeks when camping/backpacking. Standard methods of disenfecting (boiling, treating) are good against natural contaminants but there is always still the risk of problems such as this.
