The sample was collected on April 7. Eurofins issued its results on April 10. According to the lab report, the 24-hour composite found:

• 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
