Samsung Spilled Up To 763K Gallons of Sulfuric Acid Waste Into Austin Tributary (kxan.com) 56

New submitter blackprint writes: The City of Austin released a memo saying that Samsung released as much as 763,000 gallons of sulfuric acid waste into a Northeast Austin creek over a period as long as 106 days. They confirmed the leak has stopped, but no fish or macro invertebrates survived in the impacted area. They don't know if there are any long-term impacts, but pH levels in the area have returned close to normal. According to the memo, "Public access to this area is limited, and there are no nearby parks."

They have not stated the cause of the spill. "Spill investigators and scientists took a look at the area Jan. 18-19 and saw iron staining in the tributary channel consistent with a low pH environment," reports local news station KXAN, citing the memo. "WPD says it was in this tributary stretch from the Samsung plant to the main branch of Harris Branch Creek that WPD staff found no surviving aquatic life, including fish."

    According to Samsung’s report to TCEQ, the discharge stemmed from “a leak in a sump underneath a subfloor.”

      That's actually pretty a common failure. Low pH water like this would need to be contained in a sump lined with acid brick or some kind of acid resistant polymer. If it wasn't regularly inspected (most aren't), a leak will quickly eat away the concrete and find itself a way out. I've seen it before, although the leak was just into the surrounding soil and not a waterway (and also not the worst thing to ever leak out).

      1. 763k gallons over 106 days = 5 gpm, not a trivial leak but also not a flood. This is probably a swag from some poor engineer at Samsung who got a panic call when they found it because the math works out to almost precisely 5gpm. It's 200 gallons shy of 5gpm, so I bet the actual report was for 763,200. You can look them up on the TCEQ site if you're that interested.
      2. Because it is a strong, diprotic acid, a pH of 3-4 for sulfuric acid is actually a very low concentration, between 0.0005 and 0.00005 molar, or about 0.005-0.0005 wt% (molecular weight of sulfuric is close to 100g/mol). This is approximately 0.0027 mL of acid in one liter of water (gravity of 98% sulfuric is ~1.84) .... A drop of water is usually considered about 0.05 cc, so 1/18th of a drop in a liter of water. You could probably safely drink it in small quantities, even if it tasted like shit.

      While immediately bad for the aquatic life, and a complete fuckup by Samsung to not notice for this long (usually you are required have pH monitoring on outfalls to detect these kind of leaks), it is also not a long-term problem and will quickly return to normal because that's just how chemistry works.

      Now if the waste had some persistent pollutants, that's a much bigger problem because they accumulate rather than neutralize.

        Definitely a f-up by Samsung and I'd expect a review to be done by the authorities of the plant in general to see if there are more infractions coming up.

            Could still be a federal issue and not a state issue if the EPA gets involved.

      • It was wastewater, not merely diluted sulfuric acid. So the question becomes what other shit was in the wastewater and whether that will have long term effects on the tributary itself. Probably not as there was no significant effect seen in the main creek branch. Also, the leakage that made it into the tributary was probably much less than 763k gallons, as that was largely what was caught in the stormwater pond itself.

        O.o
         
        No, the dead ecosystem will not "quickly" return to normal. It will take years, if not decades... If it ever does return to normal.

      Hopefully, they will get a multimillion dollar fine, but I am not holding my breath. There is no excuse for this sort of thing. They should be monitoring the pH of their waste streams in real time. It is very easy to do, all you need is a pH meter and an alarm and you would know immediately. The plant manager should be fired and in a perfect world sent to jail.

        This is Texas, the reason companies are coming here is precisely because the government will be doing nothing. If the average joe funds it via taxes AND those taxes can't be siphoned off by the state government somehow, it can happen, but applying a regulation? Nope.

          How much involvement have you had with industrial regulatory agencies in Texas?

          I've started up 3 factories in the last 4 years in Texas. The requirements to do so weren't significantly more lax than those I started up in Illinios, Wisconsin, Indiana, and Maine in the same period.

          Texas is actually tougher in water quality than all of the states I listed, which is relevant here. For air permitting they are more likely than average to allow "de minimus" provisions but average or better after that. Waste-

          This is disingenuous. It's not just a "leaky pipe": it's what the pipe contained. You could argue that Bhopal was just a "leaky pipe" and only some gas escaped. The content of the pipes is why we have safety standards; and when those standards are violated, someone should be held accountable.
          • In this case the safety standards, specifically the stormwater pond on the property, caught most of the leak, with significantly less entering the tributary. Which is why no difference was seen in the health of the creek the tributary fed into. Indeed, the memo explicitly states as much but the idiots at kxan apparently couldn't be bothered to even read the thing,

      Pretend you didn't notice or they will raise our entertainment tax and blame it on hippy sanctions.

    • Perhaps a fine from the EPA for involuntary chemical release? Article says they found the leak during unrelated construction works so seems accidental. Court enforceable order to repopulate the creek and install monitoring equipment perhaps. Have to wonder if they audit or monitor any of their chemical processes if you cant tell your pumping several thousand gallons more of sulfuric acid into your process today than yesterday or last year. Also unclear what level of site monitoring or waste water managem

      While it's good that according to the article, "It is good that Samsung has clearly started that effort in terms of notifying all the appropriate authorities and trying to figure out what the next steps on remediation are", it doesn't forgive them that they didn't notice this over a time period of over 106 days. While most companies tend to try to hide and cover up these issues, it doesn't mean Samsung is in the complete good because some type of auditing for safety eithe

    Ok... Now I'm not, and never will claim to be, a PROFESSIONAL waste materials handler, but how in the flying fark do you -NOT- notice that more that three quarters of a MILLION GALLONS of something goes missing in your process inventories? That's almost all of one of those 50' around and 35' high tanks.

    I've worked at more responsible companies what stored waste liquids and not only did everything nasty had secondary containment (Leaks are a "when", not an "if"), there were pretty friggin' strict inspection schedules and routines, usually monthly, but some were more often.

    You're telling me that not one single person thought to themselves "huh, that tank doesn't seem to be filling up as fast as normal", or there wasn't regular enough inspections to notice the level dropping in a longer term store?

    Either I call bullshit on this being an accident, or someone needs to have their ass held accountable for gross negligence.

      Maybe they didn't do anything to comply and now they're being investigated by the regulators.

      Or perhaps their ad revenue depends on storing customer data. No point serving the page to someone if they can't make any money from them.

      It is very simple, in order to comply they have to not sell customer data. Assuming they won't sell just EU customer data to keep their regular revenue stream, then they don't have any financial motive of paying the development costs to make the change, as they won't be making money off of EU visitors.
