- akiselev 10y agoChromium, strontium, and vanadium can enter groundwater from many different sources including water seeping through concentrated deposits and industrial pollution. It's the molybdenum concentration that caught my eye because it is unusually rare due to mineral insolubility. It's only when high pressure fracing chemicals oxidize molybdenum does it become readily soluble in untapped deposits, causing it to seep down.
