US Wildfire Suppressants Rife With Toxic Heavy Metals, Study Finds 69
A new study reveals that widely used pink wildfire suppressants contain high levels of toxic heavy metals like cadmium, arsenic, and chromium, with concentrations up to 3,000 times above drinking water limits. While the government and chemical makers have long concealed up to 20% of the suppressants' ingredients as "trade secrets," researchers have confirmed their role in environmental pollution, raising concerns over their extensive use in residential areas. The Guardian reports: The suppressants are a mix of water, fertilizer, and undisclosed ingredients, while the pink color comes from added dye to show firefighters where it has been sprayed. Metals are likely used as anti-corrosion agents to prevent the plane's tankers from disintegrating, they authors wrote. The mix works by coating vegetation and lowering the amount of oxygen that could fuel the fire. The substance was dropped by as many as 25 aircraft daily to contain the devastating Los Angeles wildfires, and photos from it vividly convey the trade off, showing homes and property covered in hot pink suppression.
The metal levels in the suppressants meet federal guidelines and the authors were initially most worried about environmental contamination, but the heavy use in residential areas this year raises a new set of concerns, Daniel McCurry, one of the study's co-authors, told the Guardian. "Are the hazardous waste thresholds the appropriate bar for these to clear, or, if they're being used in a massive scale in populated neighborhoods, do we need to get stricter on permissible concentrations of toxic compounds?" McCurry asked. [...] The producer of one of the suppressants has said a new generation of the product is "greener," McCurry said, but he added "until we are able to come across some of this material and test it, we really don't know."

Any price and consequence are perfectly acceptable in order to save the Californian common smelt fish found everywhere on the planet, we humans are the parasite apparently so we deserve to burn according to some people: https://en.wikipedia.org/wiki/...

Those fish, or at least what was done to protect them, had exactly nothing to do with the fires (*). The reservoir wasn't empty because of water flow restrictions; it was empty because of repairs. The reservoirs that got slightly less water because of the smelt were in northern California, not southern California where the fires are.
For folks who don't have a concept of just how big California is, that's roughly the difference between Nashville and New Orleans. Nobody in his or her right mind would fly helicopters all the way from New Orleans to put out fires in Nashville, yet that's what our President apparently believes would have saved lives. There's really not enough crack in the world for that to make sense.
SMH.
* To be overly pedantic, the fish and the fires do have one thing in common — inadequate rainfall caused by climate change. But good luck trying to get a modern-day Republican to acknowledge that.

No disrespect intended, but California realized a very long time ago the issues you are highlighting and actually does have an interconnected water system. It's just not a pipeline. It is the California Aqueduct system (Info here: https://education.nationalgeog... [nationalgeographic.org] ). Because it is an open canal system, it very admittedly suffers from evaporation issues (which a pipeline would not suffer from). Some solutions to the evaporation problem are currently being tested, the best one (IMHO) being to shield the open canals with solar panels that would be connected to the grid.
Your call for desalination plants was also acted upon in certain regions, specifically San Diego. The largest desalination plant in the western hemisphere was constructed in Carlsbad at the cost of approximately $1 Billion Dollars and feeds into the San Diego Country Water system. It provides approximately 7% of the counties needs. ( https://en.wikipedia.org/wiki/... [wikipedia.org] )

There was never any widespread shortage of water in southern California. There was a nearby reservoir that was drained for repairs, and that may have slightly impacted things, but not much, because the helicopters couldn't fly on at least one of those first couple of days, so the dry reservoir was moot. And of course, once the helicopters were cleared to fly, they could use booms in the ocean and just dump seawater if necessary, so it's not as if they didn't have other options.

To be fair, you've got to be more precise about the "inadequate rainfall", as California has a long time (not just a few centuries) history of long periods of droughts. Population plays a part in the "inadequate", and so does the rising temperatures (hot places evaporate more quickly), but to demonstrate that a current drought is caused by climate change is difficult. This link https://water.ca.gov/drought#:... [ca.gov]. understates the case as the cycle of droughts goes back to before humans showed up.

Sure it would be better not use heavy metals to fight fires. However if you read you'd understand that those chemicals are present to among other things protect the aircraft and tanks from corrosion. Maybe you have not looked lately but large aircraft capable to disusing huge volumes of liquid over fires are not exactly cheap.
The only reason we have enough of these things is because we have built a fleet of them over years and maintained them, as well as chosen suppressants that don't destroy them. Sure we could probably find some alternatives that are more green at dramatically higher cost, we could skip the anti-corrosives and have to retire the planes and equipment sooner again at great cost or a reduced capacity.
Finally we could tax everyone more so some of our richest citizens can enjoy security security they have now and not have a little less worry about contamination from fire suppressants. We could keep taxes where they are reduce other activities. - These are policy choices and they don't get made in a vacuum.
