ZIP code 45177: Wilmington

Drinking-water compliance

A health-based violation is a contaminant above its limit or a treatment rule not followed; monitoring, reporting and public-notice violations are paperwork. Lead is the 90th-percentile result across sampled homes, not a reading at any one tap.

Byproducts and contaminants

TTHM

44.2 µg/L yearly mean in 2019, the last year in the file (limit 80); worst yearly mean 67.5, highest single sample 106; 129 samples from 2012 to 2019

HAA5

22.5 µg/L yearly mean in the last year sampled (limit 60); worst yearly mean 26.9, highest sample 43.9; 129 samples

Nitrate

highest of 96 samples was 3.8 mg/L as nitrogen (2013; limit 10); 2.56 in 2019, the last year sampled. Nitrate above 10 is unsafe for infants

Arsenic

not detected in 8 samples (limit 10)

Solvents and fuels

benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, vinyl chloride not detected in 8 samples

Bacteria

1 of 1,348 routine tap samples (0.07%) tested positive for total coliform in 2012 to 2019, 1 of 172 in 2019; E. coli never found in the 1 tap sample tested for it. Coliform itself is a warning sign; E. coli means sewage or manure reached the water

Farm chemicals

atrazine in 5 of 22 samples, highest 1.1 µg/L (limit 3); alachlor not detected in 22 samples

Metals

chromium, cadmium, barium, mercury, selenium, thallium not detected in 8 samples

EPA's file stops at 2019; Ohio EPA's Drinking Water Watch has newer results. Byproducts are judged on running yearly averages at each sampling site, so one high sample is not a violation. Nitrate and arsenic are measured where water enters the pipes.

PFAS

UCMR 5

5 samples in 2023 at the entry point to the distribution system: PFPeA 9.8, PFHxA 8.2, PFOS 7.3 ng/L

Sources

The system reported a known PFAS source near its supply

Ohio EPA 2020

1 plant tested (latest 2021-05): PFOS 14.4 ppt, against Ohio's action level of 70 ppt

Ohio EPA latest

1 plant sampled by Ohio EPA, most recently 2023-11 (Ohio EPA statewide sampling status map)

Firefighting foam: 2 fire departments or other holders in Clinton County registered 140 gallons of PFAS-based AFFF foam with Ohio EPA; the state is collecting it for disposal so it is never sprayed again.

Lithium: not detected in 4 UCMR 5 samples at Wilmington City (the method reports from 9 µg/L). Lithium is unregulated; EPA's draft health reference level is 10 µg/L, and it occurs naturally in deep groundwater, so well systems in the northwest run highest.

PFAS are the forever chemicals from firefighting foam, plating shops and non-stick coatings. One sample above 4 ng/L is not a violation; compliance is judged on running annual averages, and systems are adding carbon filters ahead of the 2029 deadline. Results are for water leaving the plant, not your tap.

Lead at the tap

Latest period

0.8 ppb in the sampling period ending 2025-12

Record

4 sampling periods since 2016, none above 10 ppb

Service lines

5,143 inventoried: 161 lead, 292 galvanized needing replacement, 2,822 unknown, 1,868 not lead (reported all required service line types)

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.

Housing age: 31% of the homes here were built before 1960 and 15% before 1940, when lead service lines, lead solder and lead paint were common; 49% predate 1980 (Census ACS 2020 to 2024).

Systems sample taps in the homes most likely to have lead pipes or solder; the 90th-percentile figure means nine in ten sampled homes were at or below it. Lead comes from the service line and the house plumbing, not the source water, so a low system result does not clear an old house. The action level drops from 15 to 10 ppb in 2027, and every lead line must be replaced within ten years of that.

Fluoride and treatment

Treatment on file: corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, lime softening, powdered activated carbon, sand or media filtration.

Measured fluoride: below the 0.2 mg/L reporting limit in 1 sample at the plant's entry points in 2019; detected samples in earlier years ran from 0.2 to 0.24 mg/L across 8 samples in 2012 to 2019 (EPA compliance monitoring). Natural fluoride in Ohio well water runs from a trace to over 2 mg/L in parts of the northwest.

The health department counts 97.8% of Clinton County residents on community water as receiving fluoridated water.

Ohio law (ORC 6109.20, 1969) makes systems serving 5,000 or more people fluoridate unless the water already carries 0.8 mg/L naturally or the community exempted itself by ordinance or referendum in the months after the law passed; smaller systems choose for themselves. The treatment list is what each system registered with EPA and can lag a plant upgrade.

Algal toxins

Raw water

64 detections at the intake across 7 bloom seasons (2017 to 2026); highest since 2024 6.66 µg/L

Treated water

never detected after treatment

Monitoring

556 samples from 2016 to 2026, latest 2026-08-19

Raw-water readings show what the plant has to remove; any detection at the intake triggers weekly paired raw and treated-water testing until two clean weeks, and carbon, ozone or chlorine destroys the toxin in nearly every case. The ten-day advisory levels for treated water are 0.3 µg/L for children under six and 1.6 µg/L for everyone else. Since November 2022 the bloom season runs June through November (sampling continues into early December), with treated water tested every two weeks the rest of the year; the 2016 to 2022 rule monitored year-round and stepped testing up to three days a week when raw water passed 5 µg/L.

Geology

12% 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 Ordovician limestone and shale known to form karst, under more than 20 ft of drift; 6 probable sinkholes inside the ZIP, where surface water can pour straight into the aquifer; nearest verified sinkhole 7.9 mi away (Ohio EPA and ODNR Geological Survey)

Injection wells

132 Class V injection wells on Ohio EPA's books inside this ZIP (22 active): 21 large septic, 108 cleanup injection, 2 vehicle waste, 1 other; these put fluids underground above or into drinking water aquifers

Water table

GR-13 OH monitoring well (ODNR), 12.6 mi away: water 8.5 ft below ground on 2026-07-06; averaged 8.7 ft in 2015 to 2019 and 9.3 ft over the latest year, so the table is running about 0.6 ft lower; range 6.8 to 11.4 ft over 3,527 readings since 2016

Nitrate risk

EPA researchers put the chance that a public water system in the Lytle Creek subwatershed exceeds the nitrate limit at 26% if it draws on groundwater and 39% 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 Sabina Wellfield (Clinton County), 12.2 mi away: 110 ft deep in limestone or dolomite (CSE Dolomite aquifer); bedrock 46 ft down; wells there yield 5 to 25 gallons a minute; sampled every 18 months. 5 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.

Sewage sludge: 132 farm fields covering 4,812 acres inside this ZIP are permitted for spreading treated biosolids, mostly from Wilmington Wwtp (1,410 acres), Dayton Wwtp (948 acres), Miamisburg Water Reclamation Facility (690 acres) (Ohio EPA). Biosolids carry nutrients and, increasingly under scrutiny, PFAS.

Sludge source: 1 permitted biosolids generator is inside this ZIP; nearest Wilmington WWTP, 0.9 mi away (a major plant); 1 within 10 miles (Ohio EPA).

State water loans: 10 projects inside this ZIP have borrowed $55.6 million from Ohio EPA's revolving loan funds since 2018 (3 sewer, storm water and runoff projects for $49.6 million; 7 drinking water projects for $6.0 million), with $5.4 million of principal forgiven. Largest: Wastewater Treatment Plant Improvements NRD (Wilmington, 2023, $46.0 million); latest: WWTP PFAS Evaluation (Wilmington, 2024, $180,795). Below-market loans are how most Ohio treatment plants and water mains get rebuilt.

Sewer planning: 93% of it is assigned to Clinton County as the designated sewage management agency under Ohio's Clean Water Act section 208 plan (generic prescriptions); 2 agencies share the ZIP. The 208 plan decides who may build and extend sewers.

Stormwater: 5% of this ZIP lies inside Ohio EPA's regulated MS4 areas, mostly the City of Wilmington storm sewer system; the towns, townships and counties that own those storm sewers hold a stormwater permit and must control what runs off streets and parking lots (2020 to 2030 designation). 14 sites with an address in this ZIP hold their own industrial stormwater permits (Polaris Industries, Azek Building Products, Inc., Mulch America and others) (EPA Facility Finder).

Plants inside this ZIP: Wilmington Wwtp (3 MGD, major).

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 Todd Fork (fully supporting); Headwaters Cowan Creek (not supporting).

Fish advisories (Ohio EPA): Cowan Lake: largemouth bass one meal a month, channel catfish two meals a week, common carp two meals a week and 1 more species (mercury); Caesar Creek Lake: channel catfish two meals a week, largemouth bass two meals a week, white crappie unrestricted (mercury). Statewide, every other fish is one meal a week because of mercury.

Nearest stream assessment (Ohio EPA): Lytle Creek Near Wilmington @ Nelson Rd. on the Lytle Creek, 1 mi away, draining 8 square miles: partial attainment of its warmwater use; fish IBI 38 of 60 (2007); bugs rated low fair; habitat QHEI 66.5 of 100. 19 assessed sites inside the ZIP, 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): 113.2 miles of designated streams cross this ZIP: 105.5 mi warmwater habitat, 7.7 mi exceptional warmwater habitat. Nearest specially protected stream: the Anderson fork (Grog run (RM 11.02) to the mouth), 6.2 mi away, a Superior High Quality Water; 6% 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 L. Miami R. Near Fort Ancient @ St. Rt. 350, 13.9 mi away, the water carried 68.63 ng/L of total PFAS (PFOA 1.4, PFOS 8 ng/L); fish fillets held 91.58 ng/g in bluegill (PFOS 70 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 Clinton County used about 194 metric tons of pesticide active ingredient, 471 kg per square mile, 23rd of Ohio's 88 counties. Largest: glyphosate 77 t, atrazine 23 t, metolachlor 14 t, acetochlor 14 t, 2,4-D 13 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 23 t of it.

Farms (2022 Census of Agriculture): 788 farms work 241,315 acres of Clinton County, with 83% of its land in cropland, 306 acres to a farm. 3,328 cattle, 39,250 hogs, 2,324 laying hens, 413 broilers, 168 turkeys; 68,880 acres of corn and 131,362 of soybeans. Sales $210 million, 10% 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.

Road salt: nearest went to Village of Harveysburg (equipment, 2024-2025), 9.5 mi away; 2 in Clinton County. H2Ohio pays for brine makers, calibrated spreaders and covered salt barns so less chloride reaches streams and wells.

The population center sits in the Lytle Creek subwatershed; its water runs on through Little Creek-Todd Fork, then Lick Run-Todd Fork, then Ferris Run-Little Miami River.

In 2015 Clinton County drew about 3 million gallons a day of fresh water (USGS): 0.9 million for public supply (27% from wells, 21,400 people served at 32 gallons a person a day at home), 0.1 million for irrigation, 0.3 million for mining; 20,600 residents drew their own well water.

EnviroAtlas, Lytle Creek: 50 to 100 acres in the Conservation Reserve Program; 3,788 acres of grain crops; 59 miles of streams (2.9 per square mile); water use of 732 thousand gallons a day for homes and 22 thousand for farms; 41 inches of rain and snow a year; 10 kg of nitrogen per hectare falling from the air each year; farm nitrogen of 0 kg per hectare a year as manure and 32 kg as synthetic fertilizer; 5% of the farmland sits on drained hydric soils; potentially restorable wetlands on farmland cover 9% of the subwatershed; 13% of the land is paved or roofed; 60% of the stream banks keep natural cover (EPA EnviroAtlas national metrics, 2010s vintages).

Stream permits: 9% of this ZIP drains to streams Ohio EPA rates high quality, where a project that fills, pipes or crosses a stream needs an individual Ohio EPA 401 water quality review; 16% drains toward high-quality waters farther down and might qualify for the Army Corps' blanket nationwide permits after a field screening and 74% can use those nationwide permits outright (Ohio EPA 401 nationwide permit eligibility map).

Caveat

3 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.

On the market (Realtor.com, August 2026): median asking price $337,125 (up 12.4% in a year), $175 per square foot for a typical 1,802 sq ft listing; 44 active listings, 28 new this month; listings spend a median 38 days on the market (down 16% from a year earlier); 25% of listings have cut their price.

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 36% from 2015 to 2025, so a gain under 36% is a loss in real terms.

Municipal income tax

Wilmington 1.5% (57% of residents); township residents outside a city or village pay none. Charged on wages and business profits where you work and, after credits, where you live.

School district income tax

Wilmington City none (83% of residents), Clinton-Massie Local 1% (17% of residents). Voted by the district and collected with the state income tax.

Sales tax

7.25% combined rate in Clinton County: Ohio's 5.75% plus county and transit levies.

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.

Busiest

SB IR-71 over Anderson Fork, 43,000 vehicles a day (2021 count)

Owners

county 62, state 43

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

Driving

about 1.2M vehicle-miles a day on the 813 counted segments inside the ZIP; the typical segment carries 2,478 vehicles

Busiest local road

city street 399, 9,389 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: 27 people died in 22 crashes inside this ZIP in 2020 to 2024 (2 pedestrians, 1 motorcyclist); 2 involved a drinking driver and 10 happened in the dark. That is 24.2 deaths a year per 100,000 residents against 10.6 across Ohio's ZIPs; deaths are counted where the crash happened, and many who die live elsewhere. (NHTSA FARS)

Air standards

Clinton County is a maintenance area for ozone (2008) (Cincinnati, OH-KY-IN, redesignated 2016), meaning it once failed that standard and must keep a plan to stay clean (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.

Chemicals

Zinc compounds 1,126 lb, Copper 437 lb, Nickel 53 lb (carcinogen)

Carcinogens

70 lb of the on-site releases were chemicals EPA lists as carcinogens

Facilities

Trend

1,862 lb on site in 2020, so down 12% over four years

Pounds are what facilities report, not what reaches anyone: a ton of ammonia to the air and an ounce of mercury to a river are not the same risk. Off-site transfers go mostly to landfills and treatment plants elsewhere.

Spills and releases

What spilled

diesel and fuel oil (17), unidentified material or sheen (11), oils and hydraulic fluid (5)

Largest

about 1,200 gallons of foam in 2022, Union Twp

Reached water

6 of them reached a creek, river, ditch or storm drain (named or unnamed)

By year

2021: 5, 2022: 7, 2023: 9, 2024: 7, 2025: 5, 2026: 5

Anyone who spills more than a reportable quantity must call Ohio EPA within 30 minutes, so the log mixes a few gallons of diesel on a highway shoulder with real releases; the reported volume is the caller's first estimate. Every report in Ohio EPA's open-data layer carries coordinates; air-pollution complaints and calls where nothing was found are left out of this count.

Oil and gas wells

Status

0 producing, 7 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.

Abandoned mines

Undermined land can subside and old workings can discharge acid mine water; ODNR's Abandoned Mine Land program funds repairs, and mine-subsidence insurance is included automatically in 26 eastern counties and offered as an option in 11 more. Maps drawn before 1977 are incomplete, so "none" means none mapped.

Quarries, pits and working mines: 1 working operation inside this ZIP in 2015 (The Melvin Stone Co., LLC, limestone); nearest The Melvin Stone Co., LLC (limestone, The Melvin Stone Co., LLC, 1,611,222 tons sold), 6.7 mi away in Clinton County; 0 within 3 miles, 2 within 10 (ODNR Industrial Minerals Locations, 2015, which includes surface and underground coal mines).

Soils and septic

Soil

Fincastle silt loam, Southern Ohio Till Plain, 0 to 2 percent slopes; Fincastle makes up 85% of the unit, 1% slope

Water

somewhat poorly drained; flooding none, ponding none

Septic

Very limited for a leach field under Ohio's rule

Basements

Very limited for dwellings with basements

Farmland

Prime farmland if drained

Elevation

1,027 feet above sea level at the ZIP's population center; Ohio runs from 455 feet where the Ohio River leaves the state to 1,549 feet at Campbell Hill

One point stands for the ZIP; soils change field by field, and a site evaluation is what the health department goes by. "Very limited" means the standard design will not work, not that nothing will.

Wetlands

427 acres pond, 328 acres forested/shrub wetland, 71 acres emergent wetland. Largest single wetland: 17 acres of freshwater forested/shrub wetland.

Vernal pools: 4 potential high-quality vernal pools covering 3.2 acres lie inside this ZIP (Ohio EPA screening): seasonal woodland pools that dry by summer, hold no fish, and are where salamanders and fairy shrimp breed.

High-quality wetlands: nearest is Culberson Woods SNP (Ohio DNR), 29 acres, 7.4 mi away; 1 within 10 miles.

Mitigation sites: nearest Hisey Park, 13.7 mi away (a pooled mitigation site); 0 within 10 miles. These are wetlands and streams built or restored to replace ones filled under Clean Water Act permits.

Assessed wetland: nearest NWCA-OH-3050, a wetland, 7.4 mi away: ORAM 74 of 100 (category 3), plant community index 70 of 100 (surveyed 2011); 1 within 10 miles. Category 3 wetlands are the state's best and hardest to fill; category 1 are degraded.

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.

Farmland

70%: 61% row crops, 8.6% pasture and hay

Crops 2025

of 66,262 cropped acres, 54% soybeans, 42% corn, 1% wheat and small grains (plus 2% wheat followed by soybeans, counted under soybeans), 2% hay and alfalfa; 12,700 acres of pasture and grass (USDA Cropland Data Layer)

Forest

Water and wetland

1.0% open water, 0.2% wetland

Paved and roofed

4% of the ZIP's surface is impervious; rain that lands there runs straight to a storm drain or stream instead of soaking in

Tree canopy

13% of the ZIP sits under tree canopy

Area

170.7 square miles of land

Land cover is classified from Landsat imagery at 30 metre pixels, so a house on a wooded lot can read as forest and a farm lane as open space. Stream health starts to slip once about 10% of a watershed is impervious, and is usually poor above 25%.

Reporting

incidents on file for 8 of 12 months of 2024 (January to August); the counts cover those months and the rates are annualized; 12,578 residents served; this department covers the 57% of the ZIP's residents in its territory, the rest fall under others

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

Nearest post office: Wilmington Post Office, 2.2 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.
