A Texas drainage district discovered an unidentified pipe discharging dark wastewater from Tesla's $1 billion lithium refinery into a public ditch in January 2026, with independent testing revealing hexavalent chromium, arsenic, and other heavy metals not monitored in Tesla's state discharge permit. The TCEQ investigation found no violations based on limited testing, but the drainage district's own lab analysis identified carcinogens and contaminants absent from the permitted pollutants list.
