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: this ZIP is not on the Ohio Department of Health's high-risk list for childhood lead testing; children on Medicaid or in pre-1978 housing with peeling paint should still be tested.

Groundwater

Under the surface

sand and gravel with till layers, part of the Scioto Buried Valley Aquifer (buried valley setting); wells there yield 25 - 100 gallons a minute, deposits > 100 ft thick

Bedrock

Tymochtee and Greenfield Dolomites, yielding 0 - 5 gpm to a well

Setting

Sand and Gravel; water table 15-30 ft down, 4-7 in/yr recharge, clay loam soil (hydrogeologic setting 7Ja); pesticide index 138

Well logs

22 drilled wells on file (392.9 per 1,000 residents), median 130 ft deep, 20 gallons a minute median test yield, water 10 ft down

Aquifers

48% of wells in bedrock, 52% in sand, gravel and other unconsolidated material; typical well drilled 1981, 6 since 2000; uses: Domestic 18, Public/Semi-Pub 1

Geology

54% 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 7.6 mi away (Ohio EPA and ODNR Geological Survey)

Water table

AU-3 OH monitoring well (ODNR), 6.7 mi away: water 6.5 ft below ground on 2026-07-06; averaged 7 ft in 2015 to 2019 and 8.8 ft over the latest year, so the table is running about 1.8 ft lower; range 4.6 to 10.7 ft over 4,195 readings since 2015

Nitrate risk

EPA researchers put the chance that a public water system in the Headwaters Scioto River subwatershed exceeds the nitrate limit at 18% if it draws on groundwater and 35% 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 Russells Point Wellfield (Logan County), 7.4 mi away: 85 ft deep in sand and gravel (Great Miami River aquifer); wells there yield 25 to 100 gallons a minute; sampled every three years. 8 active wells within 15 mi

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 7.6 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

Vulnerability index

DRASTIC 129 (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

0.123 million gallons a day design flow

Compliance

9 of the last 12 quarters with a violation; currently in significant noncompliance (Effluent - Monthly Average Limit); 29 effluent limit exceedances in 3 years

Sludge source: nearest McGuffey STP, 9.2 mi away; 1 within 10 miles (Ohio EPA).

State water loans: no Ohio EPA revolving-fund project inside this ZIP; the nearest is W. Buckeye Street & Elizabeth Street Water Line Replacement (Belle Center, 2025, $23,310), 5.9 mi away.

Sewer planning: 100% of it is assigned to Hardin County as the designated sewage management agency under Ohio's Clean Water Act section 208 plan (generic prescriptions). The 208 plan decides who may build and extend sewers.

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.

Watersheds here: Headwaters Scioto River (not supporting).

Nearest stream assessment (Ohio EPA): Scioto R. At Roundhead @ Madory Rd. on the Scioto River, 0.4 mi away, draining 28 square miles: partial attainment of its warmwater use; fish IBI 39 of 60 (2009); bug ICI 46 of 60 (2009); habitat QHEI 79.5 of 100. 4 within 3 miles, 35 within 10. Scores above about 40 (IBI), 36 (ICI) and 60 (QHEI) mean a healthy warmwater stream.

Stream designations (Ohio EPA water quality standards): no designated stream segment crosses this ZIP. Nearest specially protected stream: the Mad river (headwaters to Mac-o-chee creek (RM 51.75), 13.8 mi away, a Superior High Quality Water. Exceptional and coldwater streams are the state's healthiest; modified and limited-resource waters are channelized or ditched.

Proposed for 2026: the nearest reach Ohio EPA proposes to add to the antidegradation tiers is the Auglaize River (Headwaters to Prairie creek (RM 18.77)), 7.7 mi away, as Superior High Quality Water.

Farm chemicals (USGS estimate, 2018): farms in Hardin County used about 263 metric tons of pesticide active ingredient, 558 kg per square mile, 8th of Ohio's 88 counties. Largest: glyphosate 94 t, atrazine 51 t, metolachlor 23 t, acetochlor 23 t, 2,4-D 15 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 51 t of it.

Farms (2022 Census of Agriculture): 715 farms work 243,914 acres of Hardin County, with 76% of its land in cropland, 341 acres to a farm. 12,587 cattle, 86,404 hogs, 514 broilers; 81,903 acres of corn and 112,261 of soybeans. Sales $408 million, 49% 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.

H2Ohio: nearest project Indian Lake State Park Campground Wetland Restoration, inland flow-through wetland, funded 2023, in progress, 4.9 mi away: The Indian Lake State Park Campground Project was developed to address sediment and nutrient reduction at Indian Lake. The project will create three wetlands in...; 1 within 5 miles, 2 within 15. H2Ohio pays for wetlands, farm practices and lead line work to cut the nutrients behind Lake Erie's algae.

Source water: 100% of this ZIP drains to the river intakes of Aqua Ohio - Marion, Columbus Public Water System and sits inside their Ohio EPA source water protection area.

Watershed plan: the Headwaters Scioto River subwatershed around this ZIP's center has an Ohio EPA-approved nine-element nonpoint source plan (2021), the blueprint that makes its farms, streambanks and communities eligible for federal Section 319 runoff grants.

The population center sits in the Headwaters Scioto River subwatershed; its water runs on through Silver Creek-Scioto River, then Gander Run-Scioto River, then Wolf Creek-Scioto River.

In 2015 Hardin County drew about 5 million gallons a day of fresh water (USGS): 2.2 million for public supply (100% from wells, 18,700 people served at 72 gallons a person a day at home), 1.4 million for mining; 13,000 residents drew their own well water.

EnviroAtlas, Headwaters Scioto River: over 1,000 acres in the Conservation Reserve Program; 36,096 acres of grain crops; 112 miles of streams (1.5 per square mile); water use of 138 thousand gallons a day for homes and 24 thousand for farms; 37.9 inches of rain and snow a year; 13.5 kg of nitrogen per hectare falling from the air each year; farm nitrogen of 10.8 kg per hectare a year as manure and 52.6 kg as synthetic fertilizer; 45% of the farmland sits on drained hydric soils; potentially restorable wetlands on farmland cover 57% of the subwatershed; 0.8% of the land is paved or roofed; 14% of the stream banks keep natural cover (EPA EnviroAtlas national metrics, 2010s vintages).

Stream permits: none of this ZIP drains to streams Ohio EPA rates high quality, so stream crossings and fills here can use the Army Corps' blanket nationwide permits under Ohio EPA's standing 401 certification (Ohio EPA 401 nationwide permit eligibility map).

Building permits

The Hardin County building department reports only buildings of four or more units and commercial work to the survey (0 such units 2016 to 2025); single-family houses in its unincorporated townships are not counted here, so the zero says nothing about how many houses were built.

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.

Traffic

Trucks

1,070 a day on SR 117, 18% of its traffic

Driving

about 5K vehicle-miles a day on the 3 counted segments inside the ZIP; the typical segment carries 2,096 vehicles

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: no fatal crash was recorded inside this ZIP in 2020 to 2024 (NHTSA FARS).

Climate

Temperature

50.8°F average; typical January low 18°, July high 84°

Hot and cold days

16 days a year reach 90°F; 124 nights fall below freezing, 4 below 0°F; 42 days never climb above freezing

Rain and snow

41.5 inches of precipitation on 83 days with a tenth of an inch or more; 26 inches of snow on 10 days with an inch or more

Degree days

6,028 heating, 888 cooling (base 65°F): the higher the heating number, the bigger the winter gas bill

Drought (U.S. Drought Monitor): since 2020 Hardin County has spent 42 weeks in moderate drought or worse, 2 of them severe or worse (most recently 2 weeks in 2024), and 116 weeks at least abnormally dry. The worst since 2000 was severe drought in 2024/09; 6% of all weeks since 2000 were in drought. As of 2026-09-01: no drought.

Long run (NOAA, Hardin County): the average year ran 51.5 °F over 1996 to 2025 against 49.3 °F over 1901 to 1930, 2.2 °F warmer (1.9 °F warmer than 1951 to 1980); the warmest year on record was 2024 at 55.0 °F, and 2025 came in at 52.0 °F. Precipitation averaged 37.8 inches a year lately against 36.6 a century ago, 3% more; the wettest year was 2011 with 53.4 inches, and 2025 brought 32.8. More rain in bigger bursts is what strains storm sewers and septic fields.

Stations: Kenton (13.5 mi, temperature and snowfall; 12 years of snowfall record); Lakeview (6.9 mi, precipitation). 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.

Air quality

Worst days

98th-percentile day 21.8 µg/m³ (24-hour standard 35)

Ozone

66 ppb, 4th-highest daily 8-hour reading at Lima, 18.2 mi away (standard 70)

County AQI

Hardin County has no monitor of its own, so EPA publishes no daily index for it

Air toxics

20 in a million lifetime cancer risk from outdoor air toxics across Hardin County (EPA AirToxScreen 2020), mostly formaldehyde (16) and carbon tetrachloride (3)

Permitted sources

no permitted air source operates inside this ZIP; nearest major source Hdma - Transmission Plant - Omd in Russells Point, 7 mi (EPA ECHO)

Air standards

Hardin County meets every national air quality standard and carries no maintenance plan (EPA Green Book)

Ohio has 38 PM2.5 monitors, mostly in cities and near industry, so a rural ZIP borrows a reading from far away. 2025 includes Canadian wildfire smoke days. Air-toxics risk is EPA's modelled lifetime estimate for the county as a whole; EPA's national average is about 30 in a million, and formaldehyde, with the globally mixed carbon tetrachloride background and acetaldehyde, makes up most of it.

Oil and gas wells

Status

0 producing, 2 plugged or abandoned, the rest drilled but idle, gas storage, orphan, expired permits or unknown

Ohio has drilled since 1860, so most wells here are old, shallow and plugged; unplugged orphans and injection wells are the ones that matter for groundwater. Well-head points can be a few hundred feet off for the oldest records.

Mapped from aerial photography, mostly 2004 to 2007 (the Lake Erie watersheds were re-mapped from 2021 imagery, a few areas date from 1976 to 2005 or 2014 to 2023), so small and seasonal wetlands are undercounted and ponds dug or filled since then are missing; a site delineation decides whether a lot is jurisdictional. Emergent means marsh, forested and shrub means swamp.

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.

Source: FBI Crime Data Explorer, NIBRS incident data for Ohio, 2024 (2023 for the trend): Group A offenses per reporting agency (violent = murder, rape, robbery, aggravated assault; property = burglary, larceny, motor vehicle theft, arson), murders, rapes and assaults counted once per victim; the agency is the police department of the ZIP's largest local government (city, village or township) when it has one of its own, found in the FBI's 2023 and 2024 rosters or the USGS police station inventory, otherwise the sheriff of the ZIP's county; a rate needs at least six months of 2024 on file and is annualized from fewer than 12; the Ohio figures pool the 511 police departments and sheriff's offices with all 12 months on file · FBI Crime Data Explorer · USGS structures service

Police and post office

0 stations within 3 miles, 2 within 8.

Nearest post office: Roundhead Post Office, 0.2 mi; 1 inside this ZIP.

Townships without their own department are policed by the county sheriff, whose office may be at the county seat; the state highway patrol covers the roads. The inventory lists stations, not patrol zones. It also misses some departments and still lists some that have closed; the atlas adds the departments that reported at least six months of 2024 crimes to the FBI but had no station in it, and drops the closed and duplicate records it found.
