California Farm Use Of Oilfield Waste Water Prompts Food-Safety Inquiry CBS San Francisco

Plants can probably grow using contaminated water, but I suspect some of the chemicals they use might find their way into the produce.

At the very least, it seems like injecting chemicals into the ground would damage ground water supplies.

Nearly all the chemicals used in fracking are biodegradable. The ones that are not (and many of the ones that are) are disposed of by other means, not just dumped into water supplies or the ground. There are tons of safety regulations which apply to oil and gas operations. If you have any specific questions about specific chemicals or processes, I can run them by my husband, who is an oil and gas engineer/consultant, and get some clarification for you.

It looks to me like the information is not yet in. I would not assume using the waste water is safe until testing has been done that is thorough and is done by a third party. The oil industry will say what ever it needs to if it will improve its bottom line. Personally, I would accept information only from non-interested third parties, not from anyone who receives payment from the industry. For now, I will not be buying any Halo tangerines.

Most oil field water goes to some sort of treatment plant such as a SWD plant where it is stratified, most contaminants removed then usually injected back into the ground into an old well. Some is poured into ponds and evaporated and some is used for growing crops. Its generally just water.

fracking compounds biodegradable? That's a new one, and defies reason because the composition of fracking fluid is trade secret, so the public can never know, and even one in the trade would only know a limited number of compositions.

We do know that oilfield waste, and fracking waste in particular, can be heavy metal contaminated, manganese loaded etc. These things are not biodegradable, and often are absorbed by plants. Agreed that the only way to know would be to test the water from a specific well, since well geology heavily influences the content of waste water.
