Ordinance could allow use of sewage treatment byproduct for fertilizer and composting.
County leaders are considering a new ordinance that would allow the use of sewage sludge on agricultural land.
Sewage sludge is the solid byproduct of sewage treatment plants. Also called biosolids, sludge can be used as fertilizer and in composting but it also often contains lead, mercury and other toxic heavy metals.
The draft ordinance would replace the county’s interim rules on biosolids that have all but eliminated their use.
