History5
- 1843Village originally platted as 'Newton'; a post office had already operated under the name Pleasant Hill since 1839.
- 1866Village of Pleasant Hill formally incorporates.
- 1992Nitrate monitoring begins showing manmade-contaminant levels above the level of concern, recurring intermittently since (Below Detectable Limits up to 7.0 ppm against a 10 ppm MCL).
- 2003Village adopts a wellhead protection plan, endorsed by Ohio EPA, after a source-water assessment finds the aquifer 'high susceptibility to contamination.'
- 2023Ordinance 1130 (passed Dec. 19, 2022) sets the current bi-monthly water rate structure, effective with the billing period beginning January 1, 2023.
Treatment & pressure
How it is treated
Groundwater drawn from an aquifer along the Stillwater River, on village-owned property on the northwest side of the village, via three wells with 30-horsepower submersible pumps (290 gallons/minute combined). Chlorine is added to kill harmful bacteria before the water is pumped throughout the…

Supply stress
Ohio EPA's 2003 source water assessment rated the aquifer 'high susceptibility to contamination,' based on a relatively thin clay layer covering the aquifer, potential contaminant sources within the protection area, and manmade contaminants (nitrate) detected in treated water since 1992, ranging from below detectable limits up to 7.0 ppm…

Sewers
Sanitary
Water and sewer are billed together on a bi-monthly cycle; the village's Water & Sewer page states the flat capital-charge portion of the bill is '$15 water plus $22 sewer per billing cycle,' with a separate usage-based charge on top. The sewer treatment plant's name, capacity, and receiving stream were not confirmed in available sources.
Storm
