About this area's water

Did you know
- Greenfield publishes essentially nothing about its water system: no consumer confidence report, no water department page, and no water projects on the village's own current-projects page. Almost everything verifiable…
- EPA's administrative contact for the village water system is Jeremiah Oyer at policechief@greenfieldohio.net - the town's police chief is the person on file for the drinking water system.
- In 1988 the village bought the 29.5-mile rail line linking it to the national network for $2.4 million rather than lose freight service, making it the smallest municipality in the country to own its own railroad.
- C.R. Patterson & Sons, founded in Greenfield in 1893, is described as the first African-American-owned car company in the United States; it began building horse-drawn buggies before moving to cars, buses and trucks.
- The village's water and sewer fund was losing money every year until DLZ Ohio's rate study led to Ordinance 19-2022, which raised the water usage base rate 20% in one step in January 2023.

Supply stress
Not documented as a quantity problem. The system draws eight active wells for about 4,600 people and 2,322 connections in Greenfield, in Highland and Ross counties. No Ohio EPA source water assessment, drought study or susceptibility rating for Greenfield was located, and EPA's records show no source water protection status for the…
Sewers
Sanitary
Village-operated and struggling with wet weather. The state's 2023 grant announcement described Greenfield's collection system as plagued by severe inflow and infiltration causing wastewater to surface across the village, and awarded $750,000 in CDBG money to replace lines, service lines, wyes, manholes and catch basins in the worst…
Storm
Not documented. No village or state source located describes whether Greenfield's storm sewers are separate or combined, though the sewer projects funded catch basin replacement alongside sanitary work, which suggests intermixed drainage.
