influent

The new study is unusual in that it calculated the mass of microplastics in landfill leachate and wastewater influent and effluent.

The facility also has most of its influent pumps running again, after Tropical Storm Hilary broke five of six.

“We looked at the entire treatment process, which included the influent and effluent,” he said.

Funding includes $100,000 for Marquette County to replace influent pumps at a wastewater treatment facility.

The latter system is intact, but it is offline to protect microorganisms from ingesting influent too dirty for them from the damaged primary-treatment system.
