Much of the oil- and gas-bearing shale found in the San Juan Basin is absent in the Rio Chama Watershed.
As oil- and gas-producing strata above the Mancos were stripped and flushed by repeated glaciation and melt, the Mancos, too, was ground, out-gassed, and flushed “from oil to soil”, to provide “groundwater” and now recharge.
Drilling and fracking invariably dislodges even more toxins, carcinogens and radionucleotides from substrata.
Neutron well-logging of fertile substrata Uranium risks creating even more toxic and carcinogenic Plutonium.
Such contamination puts millions downstream at risk.
