This is the report from testing the water:

> Hexavalent chromium at 0.0104 milligrams per liter, just above the lab’s reporting limit of 0.01 mg/L. Hexavalent chromium is classified as a known human carcinogen by the US National Toxicology Program. It is the substance the Erin Brockovich case was built around.

> Arsenic at 0.0025 mg/L. That is below the federal drinking water standard of 0.01 mg/L, but present.

> Strontium at 1.17 mg/L. Mazloum’s technical report on the findings noted that long-term exposure can affect bone density and kidney function in humans and wildlife.

> Lithium and vanadium at concentrations Lazarte’s letter described as abnormally high relative to rainwater or normal groundwater.

> Elevated levels of manganese, iron, phosphorus, calcium, magnesium and potassium consistent with industrial discharge. Manganese, a battery process tracer, can have neurological effects at chronic doses. Excess phosphorus can cause algae blooms that strip oxygen from waterways.

> Ammonia in the form of nitrogen at 1.68 mg/L, amplifying the algae bloom risk.

Strip away the sensationalism, and it just doesn't seem like much? None of these levels seem to be high enough to impair health. The 1.68ppm of ammonia would likely contribute to algae growth, but not majorly, especially if properly diluted. Home aquariums regularly run between 0 and 0.25ppm of NH3 without major issues, so as long as this is diluted 6x it shouldn't impact things.

I hate elon as much as the next guy, and they should have disposed of the water properly, but it doesn't seem to be anything like them running their unpermitted power plants in Memphis.

This is an entire nothing burger. Levels are within limits and they have a permit, it was just not communicated between departments. It's a failure of the Texan democracy, not a failure of Musk.

Obviously, discharging "dark and murky" polluted water is bad. But some of the figures from the lab report don't seem that terrible:

* Hexavalent chromium at 0.0104 milligrams per liter, just above the lab’s reporting limit of 0.01 mg/L. Hexavalent chromium is classified as a known human carcinogen by the US National Toxicology Program. It is the substance the Erin Brockovich case was built around.

* Arsenic at 0.0025 mg/L. That is below the federal drinking water standard of 0.01 mg/L, but present.

The hexavalent chromium is also just barely above the California drinking water standard [1]

If I wanted to fall under that reporting limit, can I just dilute my wastewater a bit more?
cwal37•19m ago
The classic pre-EPA slogan comes to mind: "the solution to pollution is dilution".
munk-a•13m ago
The dosage makes the poison - but if it sticks around in the body dilution may slightly alleviate effects but at the cost of more widespread buildup. This is out of my field so I'm not certain if that's a concern here.
Terr_•13m ago
In some cases it still is, but it's also worth bearing in mind some of the notorious exceptions. For example, we can hardly "dilute" CFCs or CO2 any more than we did, and still suffered.
Zigurd•10m ago
Accumulation makes the... what rhymes here?
MisterTea•11m ago
That is how car manufacturers worked around the old tail pipe emission laws. They added air pumps plumbed to the exhaust manifold(s) to increase the exhaust mass diluting the stream enough to pass emissions tests. Problem solved!
SoftTalker•5m ago
Is that what a "smog pump" is? I had heard the term but never knew what it was.

Along the same lines then as other emissions equipment that reduced fuel economy but achieved the ppm criteria in the exhaust. Yes, let's address pollution by burning more fuel.

SilverElfin•24m ago
But does the amount per liter matter? The quantity matters too right? How much of these substances are being released in total? And since it’s into a drainage ditch that goes past what looks like farmland, does the higher local concentration cause more problems for the population in the area?
bayindirh•24m ago
So, it's fine as long as it's legal, then?

How about when it enters the food chain and starts to accumulate? Will the elements say that "we're under legal limits, and accumulate slowly, so we will act nice and don't poison the organism we're in?"

Love that way of thinking.

dvt•22m ago
> So, it's fine as long as it's legal, then?

> Love that way of thinking.

I mean.. yeah, kinda'? We live in a society made up of laws, that's kind of the premise. So if we don't think something is fine, we can make it illegal (and we often do).

It's a pretty good way of thinking methinks, what's your alternative?

fuzzy2•17m ago
Dunno, maybe strive to release no pollutants at all? Then we wouldn't need all the pesky big government overreach.
forshaper•12m ago
How would you do that, assuming you wanted to keep up the material standard of living that the people you care about are used to?
baggy_trough•11m ago
To exist is to pollute.
bayindirh•6m ago
But you can pollute sustainably. e.g.: Composting, biodegradable materials, etc.

or unsustainably: e.g.: PFAS. For bonus points you can do internal research and hide the reports detailing the effects accurately.

jakelsaunders94•8m ago
Taking this as a good faith engineering argument. What does that mean? What do you constitute a pollutant and how much is zero?

I guess as a contrived example your breath releases 40k PPM Co2. Have you tried aiming for no pollution?

The reality is we make things which involve pollutants, which we create laws to govern the safe disposal of. Engineers optimise for these constraints the same way you do. You wouldn’t have one k8s pod per request to ‘strive to keep the response times as low as possible’.

please stop please stop and educate yourself. I dislike that this is the top message in a forum where we’re supposed to dig deeper.

The US regulatory standards are terrible. https://www.loudounwater.org/information-hexavalent-chromium...

The actual limits are orders of magnitude lower. Educate yourself.

riversflow•15m ago
nah, there is no reason they should be discharging any hexavalent chromium, we have better, less insanely toxic ways of chroming things. trivalent chromium is much less toxic, hexavalent chromium should be banned world-wide.

what's more, i'm not finding a reason that tesla would need hexavalent chromium in battery production, which leads me to speculate that this is waste from one of their other car factories where they presumably have a hexavalent chrome line (it's a cheaper and more robust process than trivalent chrome) and they are mixing/discharging on purpose at the limit at this plant.

yaaaay hexavalent chromium and arsenic, the classics. Are they melting or plating something? Or is it just ores being ores?

Or how about clean air... who needs that?

nutjob2•20m ago
Yes, much better than ICE cars, by any measure.
cogman10•16m ago
It really is, particularly because of what it ends up replacing.

The alternative is burning and refining fossil fuels.

Louisiana has a large section of land referred to as "cancer alley". It's called that due to the released toxins from oil refining (most likely benzene).

The lithium extracted today will end up circulating in the supply chain for decades. Unlike the fossil fuels refined today which are burned tomorrow, fully releasing all their toxins.

Now, it could be cleaner. There's really no reason they couldn't distill the waste water and then reuse it.

munk-a•9m ago
I'm glad you're so forward thinking. It is a genuinely better alternative to ICE engines for numerous reasons.

The best world would be significantly lessening the need for cars but electric is a clear win over gas.

john_strinlai•28m ago
apparently, despite my thoughts going into this:

>Notably, no party has alleged that Tesla is in violation of any law. TCEQ [(Texas Commission on Environmental Quality)] has not found one. Tesla is operating under a permit the state agency issued. The dispute, instead, is about what the permit was supposed to cover, and what got left out of it.

tencentshill•20m ago
As we all know, laws as written are perfect and just, especially in Texas, especially in relation to the environment. They should stop looking into it at all, really.
john_strinlai•19m ago
that is a weird extrapolation from my comment. did you mean to reply to someone else?

i made no comment on whether the laws, as written, are appropriate or not. i just went into the article thinking that this wastewater drainage was completely off the books and was surprised to find no alleged law breaking.

rdtsc•28m ago
> Quality, the state environmental regulator known as TCEQ, had quietly issued Tesla a wastewater discharge permit on January 15, 2025.

Are permits issued loudly usually?

i think they just meant "quietly" as in not notifying the Nueces County drainage department that a permit was granted in their area.
rdtsc•8m ago
That must be it. I can see if they are normally published or announced publicly somewhere, then it makes sense but if it's not done for other permits then it's sounds like they are implying nefariousness.

aeternum•22m ago
A state investigator visited on February 12, sampled the water flowing from Tesla’s outfall pipe, ran the standard panel of conventional pollutants: dissolved solids, chlorides, sulfates, oil and grease, temperature, dissolved oxygen. Everything in that panel came back inside the bounds of Tesla’s permit. TCEQ approved its investigation report on March 20, finding no permit violation.

The article then proceeds to explain how they did all kinds of non-standard tests and still found nothing above the federal drinking water standard nor in violation of the permit. Yes Tesla is still evil and responsible because supposedly some nearby town is having a drought and people are "running out of water."

Shit like this and we wonder why the US is dependent on China for all rare earths.

> Ammonia in the form of nitrogen at 1.68 mg/L, amplifying the algae bloom risk.

If you're fear-mongering, then at least take care to fear-monger correctly. From the numbers they report, it seems like Tesla is doing a good job with wastewater treatment.

ex1fm3ta•21m ago
Lithium production produce lots of toxic material. That's why I was happy the chinese were doing it for a penny. Of course driving carbon neutral but releasing tons of poison in the nature is a questionnable equation.
tredre3•15m ago
Isn't China great? First we make them produce all our stuff, then we bash them for polluting slightly more than us westerners, who produces nothing.

We win political points for globalism, we win political points for lower cost goods, then we win political points by virtue signaling about the environment! So convenient.

My eyes glaze over any time an article uses the term "heavy metals" unironically.

This could be bad or it could not, but I simply can't take anything seriously that uses ambiguous terms so linked to woo.

nutjob2•15m ago
There is a reason China does so well refining metals like lithium and rare earths: it's difficult, resource intensive and polluting. They have about a 80% global share in lithium processing.

That doesn't matter under a communist dictatorship, but in more civilized countries people don't want it in their backyard.

what a coincidence, all they want to do is report negatively on anything that Tesla touches, I've grown skeptical on all these sort of reports, most likely other refineries have similar or worse track records, but that doesn't fit the narrative right?
TheJoeMan•12m ago
Jason Bevan, Senior Manager of Site Operations at the Robstown plant, said in a written statement that the company “routinely monitors and tests its permitted wastewater discharge” and “remains in complete compliance with all requirements of its state-issued wastewater discharge permit, including applicable water quality standards.”

What an awful character. I am thankful I don't have to deceive or tell half-truths for a paycheck. The dispute is that they are discharging things not listed in the permit, and their response is that they don't exceed the limits of the things that are listed in the permit.

I also fault the government employee who submits a sample for testing from a lithium plant and doesn't check a box "test for lithium".

I find it kinda worrying that so much of the legal weight of this case doesn't seem to be about the untreated wastewater discharge at all but only about the detail that they used a county-owned ditch to do so.

So if Tesla had dug their own ditch or built the pipe all the way to Petronila Creek, the discharge would have been no problem?

I wonder how many gallons of polluted wastewater are discharged per day by overseas refineries. Does anyone know where Tesla stacks up in the global list of lithium refiners?
