Nasty stuff in the well in the 'Couv

A reader sends along a link to this unfavorable environmental report from just north of Vancouver in Clark County:

EPA’s 2011 Expanded Site Inspection confirmed the findings of earlier studies that found hazardous substance contamination of onsite ground water and soil at Camp Bonneville.

Perchlorate was found in ground water samples collected from the site at concentrations ranging from 0.60 micrograms per liter (ug/L) to 470 ug/L. Concentrations of RDX found in ground water samples collected from the site range from 2.6 ug/L to 59 ug/L. The Ecology Model Toxics Control Act (MTCA) cleanup levels for perchlorate and RDX in ground water are 11 ug/L and 0.8 ug/L, respectively.

A subsurface soil sample collected from along the bank of North Fork Lacamas Creek revealed the presence of RDX at a concentration of 250 micrograms per kilogram (ug/kg). To protect ground water to the Ecology MTCA level of 0.8 ug/L, the corresponding soil cleanup level for RDX would be 0.3 ug/kg.

The full bad news is here. But hey, no fluoride yet. That's a relief.

Sounds like explosives residue.
