The Ohio Environmental Protection Agency received more than 440 reports of chemical spills and releases between January 2012 and mid-May 2017.
Some reports were about minor spills. Some were false alarms.
But at least a few calls were dangerous, involving large amounts of chemicals seeping into the ground in sensitive areas that feed into the aquifer. More than 3 million people rely on the aquifer for clean water.
A Dayton Daily New investigation on Sunday will look at the dangers that could have an affect on the region’s water supply.
Here’s three spills that happened in the area last year. This information comes from Ohio EPA investigation reports, memos and other documents and correspondence.
On Feb. 1, 2017, a waste disposal company in Dayton reported that one of its trucks had a 50-gallon hydraulic fluid release on Logan Avenue in southeastern part of the city.
A mechanical failure caused the hydraulic line to rupture.
But the spill occurred on the roadway, and no soils, drains or waterways were impacted, the report states.
The fluid was recovered using granular absorbents and absorbent pads.
On Feb. 26, 2017, a tractor trailer that visited a truck stop in Vandalia spilled about 150 gallons of diesel fuel on the ground.
The spill, which was caused by a saddle tank rupture, did not impact any catch basins, waterways or soils, because the fuel was contained on the pavement with granular sorbent.
On March 3, 2017, there was a fire at KM Walker Truck & Trailer Repair at 2149 Valley St. in Dayton, which is in the city of Dayton’s well-field protection area.
Containers with many gallons of used and new motor oil and transmission fluid were stored at the facility, and about 100 to 200 gallons of oily firefighting water migrated from the facility to the surrounding soil, according to an Ohio EPA report.
Oil was observed in a downspout drainage tile.
KW Walker hired an environmental remediation company to vacuum the oil. The Dayton Fire Department applied sorbent pads to try to contain the released oil. Clean-up crews removed puddled water and surface soil.
The property is located within Dayton’s five-year time of travel to the source water protection area. The soil and ground water was sampled and there was no evidence the hazardous fluids infiltrated to the water table, the report states.
March 24, 2017, the Ohio EPA responded to a report of oily run-off at an old quarry at 2401 Valley St., which came from the fire a few weeks earlier at KM Walker.
Crews found oily water behind a concrete weir in the quarry. The oil, which was on the surface of the water, did not pose a threat to the drinking water, officials said.
The oily water traveled nearly half a mile in the storm sewer from the automotive facility. Oily soil was removed and the storm water sewer was flushed.
