This is the 2025 Annual Biosolids Report for the South Bay International Wastewater Treatment Plant (SBIWTP), prepared by Veolia Water and submitted by Plant Superintendent Jacob Schmidt on February 10, 2026.

The report documents biosolids disposal activities to Mexico throughout 2025, with comprehensive monthly and daily data presented across all twelve months. Daily records track pH levels and total solids percentages for stabilized biosolids, dried sludge, and USST raw sludge, providing granular operational metrics. Monthly sampling data includes extensive chemical analysis of stabilized biosolids using EPA-approved test methods, measuring concentrations of metals (arsenic, barium, cadmium, chromium, copper, lead, nickel, zinc), nutrients (potassium, magnesium, calcium), and trace elements. Notable findings include detection of pesticides and volatile organic compounds in July samples, with Bis(2-Ethylhexyl)Phthalate identified at levels of 2.84 to 41 mg/kg and toluene detected at 680–110 μg/kg. The report also documents total solids disposal volumes by month, ranging from approximately 890 metric tons in December to 1,063 metric tons in December, with annual disposal totaling 13,641.8 metric tons. All chemical analyses include Standard Toxicity Leaching Characteristics (STLC) testing to ensure regulatory compliance, with most parameters showing non-detectable (ND) results, indicating acceptable environmental and safety standards for biosolids disposition.
