PFAS

Most homes here are on private wells, which nobody tests for PFAS unless the owner pays for it.

Source: EPA UCMR 5 occurrence data (final release, August 2026) and Ohio EPA statewide PFAS sampling 2019 to 2021 and its current status map, for the system that serves most of this ZIP; results in nanograms per litre (parts per trillion) · Ohio EPA PFAS

Lead at the tap

Most homes here are on private wells; lead there comes from the house plumbing, and only a lab test of the tap will find it.

Children: the Ohio Department of Health lists this ZIP as high-risk for childhood lead exposure, mostly from old paint and soil, so every child living here should get a blood lead test at ages 1 and 2 (Medicaid covers it, and doctors are required to order it).

Housing age: 48% of the homes here were built before 1960 and 34% before 1940, when lead service lines, lead solder and lead paint were common; 84% predate 1980 (Census ACS 2020 to 2024).

Groundwater

Under the surface

till over sand and gravel, part of the Woodington Ground Moraine Aquifer (ground moraine setting); wells there yield 5 - 25 gallons a minute, deposits 25 - 100 ft thick

Bedrock

Lockport Dolomite/sub-Lockport undifferentiated, yielding > 100 gpm to a well

Setting

Limestone; water table 15-30 ft down, 4-7 in/yr recharge, clay loam soil (hydrogeologic setting 7Ac); pesticide index 146

Well logs

403 drilled wells on file (123.3 per 1,000 residents), median 121 ft deep, 30 gallons a minute median test yield, water 20 ft down

Aquifers

65% of wells in bedrock, 35% in sand, gravel and other unconsolidated material; typical well drilled 1992, 142 since 2000; uses: Domestic 300, Agric/Irrig 43

Geology

1% of the ZIP is a sensitive geologic setting, where thin or sandy cover leaves the aquifer open to what soaks in from the surface; its population center sits on Silurian-Devonian limestone and dolomite known to form karst, under more than 20 ft of drift; nearest verified sinkhole 23.7 mi away (Ohio EPA and ODNR Geological Survey)

Injection wells

1 Class V injection well on Ohio EPA's books inside this ZIP (1 active): 1 large septic; these put fluids underground above or into drinking water aquifers

Water table

D-2 OH monitoring well (ODNR), 13.4 mi away: water 40.5 ft below ground on 2026-09-08; averaged 34.8 ft in 2015 to 2019 and 39.3 ft over the latest year, so the table is running about 4.5 ft lower; range 27 to 46.3 ft over 5,202 readings since 2015

Nitrate risk

EPA researchers put the chance that a public water system in the Gray Branch-Mississinewa River subwatershed exceeds the nitrate limit at 23% if it draws on groundwater and 49% if it draws on rivers or lakes, judged from land use, geology and past results (EnviroAtlas nitrate violation index; the typical Ohio subwatershed scores 23% for groundwater and 39% for surface water)

Quality monitoring

Ohio EPA's nearest ambient groundwater monitoring well is New Madison Wellfield (Darke County), 16.8 mi away: 166 ft deep in limestone or dolomite (Lockport Dolomite aquifer); bedrock 43 ft down; wells there yield 5 to 25 gallons a minute; sampled every three years

Vulnerability rates how easily a spill at the surface reaches the aquifer, not whether anything has. Well logs include abandoned and replaced wells, so counts overstate wells in use; a private well owner is the only one who tests it.

Aquifer exposure

Karst

the population center sits on Silurian-Devonian limestone and dolomite known to form karst, under more than 20 ft of drift; no mapped sinkhole inside the ZIP; nearest verified sinkhole 23.7 mi from the center

Wellhead protection

less than half a percent of this ZIP lies inside any public water system's five-year wellhead protection area

River intakes

2% in the 1,000-foot stream corridor zone

Vulnerability index

DRASTIC 127 (ODNR; higher means a spill at the surface reaches the aquifer more easily)

Sensitive settings are outwash plains, buried valleys, karst and shallow bedrock, mapped statewide by Ohio EPA for siting decisions. Exposure is not contamination: it says how quickly a spill, a failing tank or heavy manure would reach the water table, not whether one has.

Sewage treatment

Size

0.35 million gallons a day design flow; the system has combined sewer overflows

Compliance

6 of the last 12 quarters with a violation; no open violation; 6 effluent limit exceedances in 3 years

Other discharge permits: 2 facilities inside this ZIP other than sewage plants hold a Clean Water Act permit (factories, water plants, quarries, package plants, storm water); 13 facility-quarters with a violation in the last three years.

Sludge source: nearest Greenville WWTP, 11.5 mi away (a major plant); 0 within 10 miles (Ohio EPA).

State water loans: 1 project inside this ZIP has borrowed $625,000 from Ohio EPA's revolving loan funds since 2019 (1 sewer, storm water and runoff project for $625,000), with $625,000 of principal forgiven. Largest: Sanitary Sewer Rehabilitation Phase V (Union City, 2019, $625,000). Below-market loans are how most Ohio treatment plants and water mains get rebuilt.

Stormwater: this ZIP lies outside Ohio EPA's regulated MS4 areas, so its storm drains and ditches carry runoff without a municipal stormwater permit.

Where a home's sewage actually goes depends on the sewer district, and rural homes are on septic systems the county health department permits; the nearest plant is a proxy. Violations range from paperwork to raw discharges.

Fish advisories (Ohio EPA): Greenville Creek (All waters (Darke, Miami Counties)): largemouth bass one meal a month, smallmouth bass one meal a month (mercury); Stillwater River (Tobin Road (Cosmos) to State Route 121 (Needmore)): channel catfish one meal a month, smallmouth bass one meal a month (mercury). Statewide, every other fish is one meal a week because of mercury.

Nearest stream assessment (Ohio EPA): Dismal Creek Dst. Union City Wwtp @ Worth Rd. on the Dismal Creek, 1.2 mi away, draining 12 square miles: partial attainment of its warmwater use; fish IBI 46 of 60 (2013); bugs rated fair; habitat QHEI 52.5 of 100. 6 assessed sites inside the ZIP, 2 within 3 miles, 29 within 10. Scores above about 40 (IBI), 36 (ICI) and 60 (QHEI) mean a healthy warmwater stream.

Stream designations (Ohio EPA water quality standards): 33.9 miles of designated streams cross this ZIP: 18.3 mi modified warmwater habitat, 9.7 mi warmwater habitat, 4.2 mi exceptional warmwater habitat, 1.7 mi limited resource water. Nearest specially protected stream: the Greenville creek (Indiana state line (RM 34.48) to the mouth), 3.7 mi away, an Outstanding State Water; 10% of the ZIP lies within a mile of such a stream, where new discharges face the strictest antidegradation review. Exceptional and coldwater streams are the state's healthiest; modified and limited-resource waters are channelized or ditched.

PFAS in the river (Ohio EPA large river survey): at Stillwater R. Near Pleasant Hill @ Lauver Rd., 24.8 mi away, the water carried 81.66 ng/L of total PFAS (PFOA 1.4, PFOS 1 ng/L); fish fillets held 21.483 ng/g in bluegill and 7.349 ng/g in catfish (PFOS 13 in bluegill). Drinking water limits are 4 ng/L for PFOA and PFOS; river water is not drinking water, but treatment plants that draw from it start from these numbers.

Farm chemicals (USGS estimate, 2018): farms in Darke County used about 341 metric tons of pesticide active ingredient, 568 kg per square mile, 6th of Ohio's 88 counties. Largest: glyphosate 119 t, atrazine 69 t, acetochlor 30 t, metolachlor 30 t, 2,4-D 19 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 69 t of it.

Farms (2022 Census of Agriculture): 1,761 farms work 366,642 acres of Darke County, with 87.7% of its land in cropland, 208 acres to a farm. 54,582 cattle, 356,183 hogs, 8,610,584 laying hens, 43,868 broilers, 818,320 turkeys; 140,854 acres of corn and 154,219 of soybeans. Sales $1194 million, 76% from animals and animal products. Manure and fertilizer from farms like these carry the phosphorus and nitrogen behind Ohio's algae and nitrate problems; withheld figures protect individual farms.

A watershed unit fails when any sampled stream in it fails; ditches in flat farm country fail on habitat and nutrients, city creeks on bacteria and sediment. Ohio's own report is at epa.ohio.gov; the EPA link on each unit's report page has the sampling detail.

Caveat

2 of the ten years had fewer than 12 months reported by the permit office; the Census Bureau estimates the missing months, so those counts are partly or wholly imputed

Survey counts are permits issued, not houses finished, and cover new residential construction only: additions, remodels, garages and commercial buildings are not in the survey. Values are the applicants' estimates. Where a city runs the building department for its township neighbours, the city's figure covers them too.

Series

tracked since 2001; the index stops at 2022 because there were too few transactions after that

Zillow's typical home value here is $158K (2026-07), up 11% over the year, up 49% over five years and up 109% over ten.

On the market (Realtor.com, August 2026): median asking price $150,000, $128 per square foot for a typical 1,295 sq ft listing; 9 active listings, 0 new this month; listings spend a median 57 days on the market; 47% of listings have cut their price. Realtor.com flags this ZIP's figures this month as low quality (9 active listings), so the asking price is not a market median.

The index follows the same houses through repeat sales and refinance appraisals on conforming mortgages, so it measures price change rather than the price level (the Homes card has the median value). Consumer prices rose about 28% from 2012 to 2022, so a gain under 28% is a loss in real terms.

A mill is $1 per $1,000 of taxable value, and taxable value is 35% of market value. Effective rates fall as values rise because Ohio holds most voted levies to the dollars first approved. County, municipal or township, library, park and vocational-school levies are added on the same bill and are not counted here.

Rail crossings

7 with gates; railroads: CSX (8). Busiest crossing: 18 trains a day reported; fastest line 60 mph.

Darke County has logged 4 rail accidents since 2010, 3 of them derailments (FRA Form 54). Yard mishaps at walking speed dominate; main-line derailments are the rare, dangerous ones.

Train counts and speeds are the railroad's last inventory update. Crossings with only crossbucks rely on the driver; Ohio has averaged about 77 crossing collisions a year from 2010 to 2025 (FRA Form 57), between 64 and 87 in a year.

Bridges

Age

typical bridge built 1989, 4 built before 1950; oldest 1917, Zumbrum over Lateral Stillwater R

Busiest

SR-47 over Grays Branch, 1,895 vehicles a day (2015 count)

Owners

county 50, state 4

Ratings come from the inspection every bridge gets at least every two years; poor means deterioration that needs repair, not imminent danger. FHWA's file is a yearly snapshot with inspections through early 2025, so a bridge replaced, re-rated or closed since then still shows its old rating here; ODOT's TIMS bridge inventory carries the current one. Traffic figures are the average daily counts the bridge owners filed with the inventory; most Ohio counts date from 2015 and some are older. County engineers own most of Ohio's small bridges and ODOT the big ones.

Traffic

Trucks

191 a day on SR 571, 6% of its traffic

Driving

about 45K vehicle-miles a day on the 120 counted segments inside the ZIP; the typical segment carries 1,124 vehicles

Busiest local road

county road 12, 2,946 vehicles a day

Annual average daily traffic is both directions combined, averaged over the year. County, township and city roads are labelled by their route number, which ODOT uses instead of the street name. Most city streets have no count, so the busiest local road is the busiest counted one. Interchange ramps are left out of the busiest-road pick; a ZIP with nothing but ramps shows one labelled ramp and its ODOT number.

Road deaths: 1 person died in 1 crash inside this ZIP in 2020 to 2024; 0 involved a drinking driver and 0 happened in the dark. Too few people live here for a per-resident rate to mean much; deaths are counted where the crash happened, and many who die on through roads live elsewhere. (NHTSA FARS)

Climate

Temperature

51.9°F average; typical January low 19°, July high 85°

Hot and cold days

12 days a year reach 90°F; 126 nights fall below freezing, 6 below 0°F; 39 days never climb above freezing

Rain and snow

40.3 inches of precipitation on 78 days with a tenth of an inch or more; 26 inches of snow on 13 days with an inch or more

Degree days

5,672 heating, 933 cooling (base 65°F): the higher the heating number, the bigger the winter gas bill

Drought (U.S. Drought Monitor): since 2020 Darke County has spent 38 weeks in moderate drought or worse, and 124 weeks at least abnormally dry. The worst since 2000 was severe drought in 2012/07; 7% of all weeks since 2000 were in drought. As of 2026-09-01: no drought.

Long run (NOAA, Darke County): the average year ran 51.8 °F over 1996 to 2025 against 50.1 °F over 1901 to 1930, 1.7 °F warmer (1.9 °F warmer than 1951 to 1980); the warmest year on record was 2024 at 54.7 °F, and 2025 came in at 51.9 °F. Precipitation averaged 40.9 inches a year lately against 38.7 a century ago, 6% more; the wettest year was 1950 with 53.7 inches, and 2025 brought 37.8. More rain in bigger bursts is what strains storm sewers and septic fields.

Stations: Greenville WTP (10 mi, temperature and precipitation); Versailles (15.3 mi, snowfall; 14 years of snowfall record). Normals are thirty-year averages, so a single winter can run far above or below them; NOAA marks this snowfall normal provisional because the station record is too short or too patchy for a standard normal, and the temperature and precipitation figures here skip stations with under 10 years.

Unemployment-insurance records tie each job to a workplace and a home address; large employers sometimes report every worker at a headquarters, which inflates a few ZIPs. Self-employment, the military, the Postal Service, most farm work and a large part of federal civilian employment are missing (federal jobs come from OPM records that omit several agencies and, in practice, most of Wright-Patterson).

Rates cover the whole agency's territory, not this ZIP alone: a city's downtown and its quiet edges share one number. Murders, rapes and assaults are counted once per victim and other offenses once per incident, as the FBI's Crime Data Explorer does; a large department's figures can still fall somewhat short of the Explorer's, which takes in later submissions, and a sheriff's population is only the unincorporated area it serves.
