Contaminated water from the closed Fulton County Landfill is being treated at Pettisville, Ziad Musallam, director of public utilities for Fulton County, said last week.
The process has been going on for about 10 years.
The landfill, located on the southeastern corner of County Roads F and 9, was closed more than 30 years ago, but groundwater seeps into and out of the site.
The county installed a tile system around a portion of the landfill, which collects the contaminated water, now referred to as “leachate.”
That water, or leachate, is then “pumped to aerated lagoons located next to the landfill,” Musallam said in an email message.
“The pretreated leachate is then hauled to the Pettisville Wastewater Treatment Plant for additional treatment prior to final discharge into an unnamed tributary to Brush Creek.”
Musallam said the Pettisville wastewater treatment facility is one that was approved by the Ohio Environmental Protection Agency.
“We decided to use Pettisville as the most efficient method for leachate disposal,” he said.
The Pettisville wastewater facility design is based on the controlled-discharge concept.
Twice a year, in November and April, the lagoons at the Pettisville facility discharge treated wastewater, he said.
“The entire process has been permitted and monitored by the Ohio EPA through a discharge permit,” Musallam said.
At one time decades ago, the Archbold Water Treatment Plant used Brush Creek as a raw water source.
A raw water pumping station was built on the Tiffin River, and an underground pipeline was constructed to Archbold.
Today, the Brush Creek water intake is only used as an emergency backup supply.
The leachate is hauled from the pretreatment lagoons near the landfill to Pettisville in a county-owned truck, operated and driven by a county employee.
Private contractors are not used to haul leachate.
In addition, Musallam said no other waste is trucked to Pettisville: not industrial waste or waste pumped from septic tanks by private contractors.
Fulton County officials have discussed constructing their own wastewater treatment plant that would serve the Delta industrial corridor. It would also treat leachate from the county landfill.
In May 2013, the commissioners were considering a plant capable of treating 600,000 to 1 million gallons of wastewater per day.
By comparison, the Archbold Wastewater Treatment Plant is rated for 2.5 million gallons per day.
In 2013, the estimated cost of that plant was $7 million.
Musallam said the decision on whether or not to construct the plant is “subject to the availability of the necessary customer base.”
