Are there metals in biosolids?
Yes. Some metals, such as nickel, zinc and copper can be found in biosolids. Many of the trace metals in biosolids serve as micronutrients that are essential for healthy plant growth. EBMUD regularly monitors and tests our biosolids to ensure they meet all regulatory and/or quality standards for their intended use. We also have strict pre-treatment and monitoring requirements for industrial and commercial facilities so that metals and other pollutants are reduced or removed before the wastewater is discharged to EBMUDs treatment plant.
