I am concerned about fish going into the compost bin since it is known to have mercury. How can Cedar Grove be sure there are no metals coming in?
Cedar Grove tests all batches of compost for 14 metals prior to sale, to ensure compliance with Washington State regulations (for 9 metals plus other contaminants) and voluntary compliance with the US Composting Council Seal of Testing assurance program. Cedar Grove Compost is consistently well below the safe limits for metals set by Washington Department of Ecology and the USEPA. The USEPA standards are set to protect children who eat soil, and WDOE’s standards are even more restrictive. A recent review of test results from the past four years showed that Mercury has not been detected at any level in Cedar Grove Compost during that period.
