AT&T May Have Nearly 200,000 Miles of Lead-Covered Phone Cables Across US (arstechnica.com) 103

An anonymous reader quotes a report from Ars Technica: AT&T's legacy telephone network may have nearly 200,000 miles of lead-covered cables, according to an estimate by AT&T submitted in a court filing. "Based on its records, AT&T estimates that lead-clad cables represent less than 10 percent of its copper footprint of roughly two million sheath miles of cable, the overwhelming majority of which remains in active service," AT&T wrote in a court filing yesterday in US District Court for the Eastern District of California. "More than two thirds of its lead-clad cabling is either buried or in conduit, followed by aerial cable, and with a very small portion running underwater. There are varying costs of installation, maintenance, and removal by cable type (aerial, buried, buried in conduit, underwater)."

Reacting to the court filing, financial analyst firm Raymond James & Associates wrote in a research note, "AT&T is telling us that the total exposure is 200,000 route miles or less." With about two-thirds of the lead cables either buried or installed inside conduit, "We believe the implication for AT&T's data is that the route miles that should be addressed most immediately is about 3.3 percent (or less)," the analyst firm wrote. AT&T's new court filing came in a case filed against AT&T subsidiary Pacific Bell by the California Sportfishing Protection Alliance (CSPA) in January 2021. The sportfishing group sued AT&T over cables that are allegedly "damaged and discharging lead into Lake Tahoe."

The two underwater cables run along the bottom of the western side of Lake Tahoe for a total of eight miles. AT&T "contends that it stopped using the Cables in or around the 1980s or earlier, that the Easements therefore have terminated, and that Defendant no longer owns the Cables," according to a November 2021 settlement. AT&T agreed in that settlement to remove the cables but now says it is at an "impasse" with the CSPA regarding removal. "In this matter, AT&T has always maintained that its lead-clad telecommunications cables pose no danger to those who work and play in the waters of Lake Tahoe, but in 2021, AT&T agreed to remove them simply to avoid the expense of litigation," an AT&T lawyer at the firm Paul Hastings wrote yesterday in a letter to the plaintiff that was attached to the court filing. [...]

AT&T's stance that it won't remove the Lake Tahoe cables any time soon is apparently a surprise to the plaintiff. The CSPA said in a court filing last week that in a Zoom meeting on July 10, "AT&T confirmed that it is prepared to commence the removal process on September 6, 2023, as long as the new permit request that AT&T submitted to State Parks in May is approved by State Park." AT&T's filing said the company never "confirmed" that it is prepared to start the cable removal process on September 6. The CSPA argues that the lead-covered cables "have leached, are leaching, and will continue to leach lead into the waters of Lake Tahoe, and that such leaching may present an imminent and substantial endangerment to human health or the environment."
Last week, the Wall Street Journal published an investigative report that found evidence of more than 2,000 lead-covered telephone cables installed across the U.S. Teleco stock prices plummeted as a result, since the remediation could cost the telecom industry $60 billion.

While members of Congress are putting pressure on telecom companies to act, AT&T does appear to be taking new actions as a result of the investigation. "AT&T is working with union partners to add a voluntary testing program for any employee who works with or has worked with lead-clad cables," which "expands on AT&T's previous practice of providing blood-lead testing for technicians involved in lead-clad cable removal," the company said in its letter to the plaintiff yesterday. AT&T said it is also conducting new testing and site visits at certain locations.

AT&T's stock slid to a 30-year low following the news.

          I'm actually hesitant to fine them for something that was perfectly legal when they did it. And while I'm a big believer in the leaded gasoline->crime theory, on the scale of things, leaded gasoline is a lot more dangerous because it's an inhalation hazard, then lead paint because kids can eat the chips, but this is apparently restricted to just around the cable, probably a couple feet down. We also don't know the levels.

          So yeah, not something to be allowing in installs now, but as you said, is it worth the extra exposure people will get from disturbing it, outside of specific situations. Something like "replace when found"?

    Nor will extracting damage$ on behalf of some possibly fictional victim of these lead sheathed cables.

    • The handling and exposure to actually extract, replace and dispose of the cable will likely be significantly more hazardous to those required to do the work than the potential impact to the environment which is limited to soil within a foot or so of the cables at most and is only at a level that would have negligible impact to the environment as a whole and is similar to the replacements cables made from copper and aluminium.

          As someone who deals with a lot of telcomm services from various providers, let me simplify and make more accurate your statement: ATT causes brain damage.

        • What's the ppm of lead contamination in the lake? How much worse is it going to get from leaving the cable there, and how much worse will it get from disturbing the cable during removal?

          What was the ppm of lead contamination before installation of the cable?

          Not saying you're wrong per se, but removal of the cable might not be the safest course of action.

          • No safe level of lead.
            How is leaving lead in place where it will continue to leach into water better than removing it?

            • The action level for drinking water is usually 15ppb in more than 10% of samples. If it isn't drinking water then natural sources of lead can push it higher without any relevant agency taking action. Plus there could be other man made contamination.

              It would help to know what additional contamination stems from the lead-clad cabling.

              Furthermore, that cable probably won't leech forever. It may have already reached chemical equilibrium with the environment to the point that it is now coated in a stable oxide

              • Yeah, so rodents, floods, earthquakes, digging for an independent reason, children playing, other animals etc. will NEVER disturb the existing homeostasis ?

                Not to mention disturbances in the air, causing acid rain, again further leaching the lead into the environment. NEVER is a long time.

        • Lead contamination spreads to the entire body of water and into drinking water.

      Because lead is one of the few things that works in those environments, it doesn’t leach like plastics and oils do, it doesn’t rust like steel or other metals do, it can handle different pH levels in the soil without needing to replace every so often.

      Lead is useful, yes, it contaminates the soil around it, but the leaching from lead into the environment is very slow over time (hence why we use it, because other metals and plastics degrade much quicker) but unless you EAT the dirt, you aren’t in any danger of lead poisoning (at which point you will probably have a ton of other health issues like tetanus, anthrax, valley fever or botulism).

      • Rats, no mod points. Oh well, yes metallic lead protects the wires inside the bundle very well. If some does corrode it doesn't go far the the soil, as soon as the lead finds a sulfate or sulfide ion it grabs it and now it's dirt again.

        Lead dissolves in nitric acid, acetic acid, a little in citric acid, and in hot hydrochloric acid. Otherwise it pretty much just sits there. Oh, and fluorosilicic acid will dissolve it too.

    I'm voting for a or c. I would bet large money that b never happens.

  • This is basic chemistry.

  • Even the ancient Greeks knew too much lead was bad. When were these cables laid? Who thought lead was a proper material to use in water? ATT is completely corrupt and incompetent. Short their stock and cut off the welfare checks.
  • Nuclear power pays a certain amount of kWh towards spent fuel fund as well as tearing down the power plant.
    America need to require that all businesses that are working in hazmat or putting anything on/in public land to put $ into a fund as they progress through sales.
    For example, each mine/oil well/gas station/utilities should be required to put into an individualized fund designed to close down the operation safely. For example, if ATT had contributed a .001/call to a fund to remove the cables when don

    "Socialize the negative externalities, privatize the profits (hallowed be their names). Screw you, plebs."

  • Yet another duplicate post. AT&T appears to be dire need of a bailout.
  • Post a map of the lead covered cables along with a note "Please don't steal this lead to cast your own bullets." It's not like they give away tire balancing weights anymore. Actually, scrap lead is ~$1/pound, about like aluminum and zinc. It's not close to copper, but not all meth heads can afford to be choosy.
  • the people that know how to maintain these have retired.

Think of it! With VLSI we can pack 100 ENIACs in 1 sq. cm.!
