Heavy metals of concern b/c are potential toxicity to humans and aquatic organisms
Several reasons for testing:

(
point to site map for LG!)
:
concerns of abandoned camps and possibility of improper chemical storage causing leaching into water
Spot Site 9 (point to LG site map!):
Bob Hubbard expressed concern that arsenic was present in the well overflow that was entering the lake

*Spot Site 9 - 0.2 ppm
compare to new proposal for 0.01ppm - our value 20 times higher than this value therefore not advisable
