ZIP code 43302: Marion

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

35.4 µg/L yearly mean in 2019, the last year in the file (limit 80); worst yearly mean 77.3, highest single sample 146.6; 122 samples from 2012 to 2019

HAA5

17.7 µg/L yearly mean in the last year sampled (limit 60); worst yearly mean 29.4, highest sample 57; 122 samples

Nitrate

highest of 98 samples was 10.8 mg/L as nitrogen (2019; limit 10), 1 sample over the limit; 10.8 in 2019, the last year sampled. Nitrate above 10 is unsafe for infants

Arsenic

not detected in 8 samples (limit 10)

Radioactivity

highest results: combined radium 0.9 pCi/L (limit 5)

Solvents and fuels

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

Bacteria

0 of 4,906 routine tap samples (0%) tested positive for total coliform in 2012 to 2019, 0 of 612 in 2019. Coliform itself is a warning sign; E. coli means sewage or manure reached the water

Farm chemicals

atrazine in 19 of 39 samples, highest 8.7 µg/L (limit 3, 2 over); not detected: alachlor in 39 samples, 2,4-D in 1 sample

Metals

barium in 1 of 8 samples, highest 11 µg/L (limit 2,000); chromium, cadmium, 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.

Source: EPA Six-Year Review 4 compliance monitoring data, 2012 to 2019 (TTHM, HAA5 and coliform from distribution-system samples of Aqua Ohio - Marion; nitrate, arsenic, radionuclides, solvents, herbicides and metals from the entry points of the same system); non-detects counted as zero

PFAS

UCMR 5

4 samples in 2023 to 2024 at the entry point to the distribution system: none of the 29 PFAS detected

Ohio EPA 2020

1 plant tested (latest 2020-10): nothing detected for the six PFAS tested

Ohio EPA latest

1 plant sampled by Ohio EPA, most recently 2025-07 (Ohio EPA statewide sampling status map)

Firefighting foam: 4 fire departments or other holders in Marion County registered 1,295 gallons of PFAS-based AFFF foam with Ohio EPA, 40 gallons in opened containers; the state is collecting it for disposal so it is never sprayed again.

Lithium: found in 4 of 4 UCMR 5 samples at Aqua Ohio - Marion, highest 19.4 µg/L (detections averaged 18.2), last sampled 2024. 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

3.7 ppb in the sampling period ending 2023-12

Highest since 2016

4.4 ppb (2017-12); never above 10 ppb in 4 periods

Service lines

19,181 inventoried: 3,371 lead, 228 galvanized needing replacement, 6,576 unknown, 9,006 not lead (reported all required service line types)

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: 47% of the homes here were built before 1960 and 28% before 1940, when lead service lines, lead solder and lead paint were common; 75% 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: aeration, chloramine disinfection, corrosion control, coagulation and settling, chlorine disinfection, lime softening, powdered activated carbon, sand or media filtration.

Measured fluoride: 0.91 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.88 to 1.21 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 100% of Marion 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

1 detection at the intake across 1 bloom season (2018); none since 2024

Treated water

never detected after treatment

Monitoring

309 samples from 2016 to 2026, latest 2026-08-24

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.

Wellhead protection

8% of this ZIP lies inside Ohio EPA source water protection areas for 20 public water systems (Aqua Ohio - Marion, Pleasant Acres Mobile Home Community Llc, Pcm Aria Marion Llc), 2% inside inner management zones, the ground a well draws from within a year; the largest, Aqua Ohio - Marion, is rated high with water quality impacts susceptibility in a carbonate bedrock setting

Geology

23% 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 10.8 mi away (Ohio EPA and ODNR Geological Survey)

Injection wells

163 Class V injection wells on Ohio EPA's books inside this ZIP (162 active): 26 large septic, 136 cleanup injection, 1 vehicle waste; these put fluids underground above or into drinking water aquifers

Water table

MN-2 OH monitoring well (ODNR), 3.5 mi away: water 38.2 ft below ground on 2026-07-15; averaged 28.9 ft in 2015 to 2019 and 38.9 ft over the latest year, so the table is running about 10.0 ft lower; range 22.2 to 42.3 ft over 3,956 readings since 2015

Nitrate risk

EPA researchers put the chance that a public water system in the City of Marion-Little Scioto River subwatershed exceeds the nitrate limit at 17% if it draws on groundwater and 40% 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 Ridgedale HS (Marion County), 5.2 mi away: 200 ft deep in limestone or dolomite (Undiff Salina Dolom aquifer); bedrock 87 ft down; wells there yield 5 to 25 gallons a minute; sampled every three years. 7 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 treatment

Size

10.5 million gallons a day design flow; a major facility; the system has combined sewer overflows

Compliance

11 of the last 12 quarters with a violation; currently in violation (not significant); 11 effluent limit exceedances in 3 years

Combined sewer overflows: 3 outfalls inside this ZIP, 0 within 3 miles, permitted to City of Marion, Div of Water Pollution Control. In heavy rain these release untreated sewage mixed with storm water.

Other discharge permits: 17 facilities inside this ZIP other than sewage plants hold a Clean Water Act permit (factories, water plants, quarries, package plants, storm water); 1 in significant noncompliance; 46 facility-quarters with a violation in the last three years; largest: The Back Rowe (in significant noncompliance); Apple Lane Subdivision (0.0032 MGD).

Sewage sludge: 66 farm fields covering 5,879 acres inside this ZIP are permitted for spreading treated biosolids, mostly from Marion Wpc (4,986 acres), Sd No 7 Water Reclamation Plant (772 acres), Mt Gilead Wwtp (98 acres); 5 more retired (Ohio EPA). Biosolids carry nutrients and, increasingly under scrutiny, PFAS.

Sludge source: 4 permitted biosolids generators are inside this ZIP; nearest Marion WPC, 3 mi away (a major plant); 5 within 10 miles (Ohio EPA).

State water loans: 8 projects inside this ZIP have borrowed $64.4 million from Ohio EPA's revolving loan funds since 2010 (6 sewer, storm water and runoff projects for $54.0 million; 2 drinking water projects for $10.4 million), with $9.5 million of principal forgiven. Largest: WPC Treatment Enhancement Project CSO (Marion, 2019, $30.9 million); latest: WPCP Facility Plan (Marion, 2026, $372,000). Below-market loans are how most Ohio treatment plants and water mains get rebuilt.

Sewer planning: 89% of it is assigned to Marion County as the designated sewage management agency under Ohio's Clean Water Act section 208 plan (generic prescriptions); 6 agencies share the ZIP. The 208 plan decides who may build and extend sewers.

Stormwater: 6% of this ZIP lies inside Ohio EPA's regulated MS4 areas, mostly the City of Marion 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). 26 sites with an address in this ZIP hold their own industrial stormwater permits (Nex Transport, Steam Turbine Alternative Resources, Marion Industries Inc and others) (EPA Facility Finder).

Plants inside this ZIP: City of Marion, Div of Water Pollution Control (10.5 MGD, major, CSO); Fountain Place Wwtp (0.1 MGD); Grandview Estates Sd 2A (0.28 MGD); Sd No 7 Water Reclamation Plant (1.75 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 Little Scioto River (not supporting); Rock Fork (not supporting).

Fish advisories (Ohio EPA): Little Scioto River (State Route 739 near Marion to Holland Road near Marion (Marion County)): do not eat; all species do not eat (PAHs); Scioto River (U.S. Route 68 (Kenton) to Ostrander Road (Warrensburg)): northern pike one meal a month, saugeye one meal a month, smallmouth bass one meal a month and 2 more species (PCBs, mercury); Olentangy River (State Route 95, Claridon, to mouth (Scioto River) (Delaware, Franklin, Marion Counties)): channel catfish two meals a week (mercury). Statewide, every other fish is one meal a week because of mercury.

Nearest stream assessment (Ohio EPA): Grave Creek At Marion @ Osu Marion Campus on the Grave Creek, 1.8 mi away, draining 5 square miles: non attainment of its warmwater use; fish IBI 26 of 60 (2009); bugs rated poor; habitat QHEI 37.5 of 100. 20 assessed sites inside the ZIP, 4 within 3 miles, 25 within 10. Scores above about 40 (IBI), 36 (ICI) and 60 (QHEI) mean a healthy warmwater stream.

Stream designations (Ohio EPA water quality standards): 128.8 miles of designated streams cross this ZIP: 81.9 mi warmwater habitat, 35.5 mi modified warmwater habitat, 11.4 mi limited resource water. Nearest specially protected stream: the Alum creek (headwaters to West branch (RM 42.8)), 16 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 Sandusky River (Grass run (RM 96.61) to Roger Young Memorial park in Fremont (RM 16.6)), 12.3 mi away, as Outstanding State Water.

Critical habitat: federally designated critical habitat for the snuffbox mussel (endangered, 2026) crosses this ZIP, so federal permits for work in those waters must avoid harming it (U.S. Fish and Wildlife Service).

PFAS in the river (Ohio EPA large river survey): at Scioto R. Dst L. Scioto R, Adj Prospect-Upper Sandusky Rd., 7.2 mi away, the water carried 238.67 ng/L of total PFAS (PFOA 2.3, PFOS 27 ng/L); fish fillets held 31.89 ng/g in bluegill and 20.57 ng/g in catfish (PFOS 11 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 Marion County used about 228 metric tons of pesticide active ingredient, 563 kg per square mile, 7th of Ohio's 88 counties. Largest: glyphosate 87 t, atrazine 31 t, metolachlor 27 t, acetochlor 12 t, 2,4-D 8 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 31 t of it.

Farms (2022 Census of Agriculture): 596 farms work 213,065 acres of Marion County, with 75.4% of its land in cropland, 357 acres to a farm. 5,461 cattle, 91,877 hogs, 2,196 laying hens, 1,240 broilers; 61,042 acres of corn and 112,480 of soybeans. Sales $221 million, 28% 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.

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.

Zillow's typical home value here is $170K (2026-07), up 5% over the year, up 33% over five years and up 115% over ten.

On the market (Realtor.com, August 2026): median asking price $185,000 (up 3.1% in a year), $140 per square foot for a typical 1,503 sq ft listing; 120 active listings, 64 new this month; listings spend a median 40 days on the market (up 18% from a year earlier); 30% 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

Marion 2% (67% 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

Marion City none (54% of residents), River Valley Local 1% (22% of residents), Pleasant Local 1% (15% of residents), Ridgedale Local 1% (6% of residents), Elgin Local 0.75% (3% of residents). Voted by the district and collected with the state income tax.

Sales tax

7.25% combined rate in Marion County: Ohio's 5.75% plus county and transit levies; this ZIP straddles counties or transit districts, so the rate depends on the address.

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.

Collisions: 37 crossing incidents reported to the FRA inside this ZIP since 2010 (3 killed, 17 injured), the latest in 2026; most at Silver Street in Marion (3) and Center Street in Marion (3).

Train accidents: 5 rail equipment accidents inside this ZIP since 2010 (2 derailments); $768,928 in damage. Latest: 2025, fire/violent rupture (CSX Transportation); the most common cause here is human factor - track.

Marion County has logged 4 rail accidents since 2010, 1 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 1971, 11 built before 1950; oldest 1900, County Road 25 over Br Over Prairie Run

Busiest

SR 95 over Graves Creek, 23,882 vehicles a day (2015 count)

Owners

Rated poor

SR 231 over US-23 (1968, 1,476 a day); County Road 148 over Br Over Riffle Creek (1965, 504 a day) and 2 more

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.

about 1.2M vehicle-miles a day on the 1,100 counted segments inside the ZIP; the typical segment carries 3,230 vehicles

Busiest local road

city street 551, 10,262 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: 32 people died in 30 crashes inside this ZIP in 2020 to 2024 (2 pedestrians, 6 motorcyclists); 2 involved a drinking driver and 10 happened in the dark; most on US-23 (5). That is 11.8 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)

Drought (U.S. Drought Monitor): since 2020 Marion County has spent 32 weeks in moderate drought or worse, 4 of them severe or worse (most recently 4 weeks in 2024), and 96 weeks at least abnormally dry. The worst since 2000 was severe drought in 2024/11; 5% of all weeks since 2000 were in drought. As of 2026-09-01: no drought.

Long run (NOAA, Marion County): the average year ran 51.6 °F over 1996 to 2025 against 49.6 °F over 1901 to 1930, 2.0 °F warmer (1.9 °F warmer than 1951 to 1980); the warmest year on record was 2024 at 55.1 °F, and 2025 came in at 51.7 °F. Precipitation averaged 37.8 inches a year lately against 37.8 a century ago, 0% less; the wettest year was 2011 with 53.5 inches, and 2025 brought 32.2. More rain in bigger bursts is what strains storm sewers and septic fields.

Stations: Marion 2 N (1.9 mi, temperature and precipitation and snowfall; 12 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.

Toxic releases

Where it went

133,523 lb to the air, 6 lb to surface water, 0 lb to land or underground injection; another 1.5 million lb was shipped off site for disposal or release

Chemicals

Certain glycol ethers 74,183 lb, Methyl isobutyl ketone 13,987 lb (carcinogen), Acetaldehyde 9,850 lb (carcinogen)

Carcinogens

33,061 lb of the on-site releases were chemicals EPA lists as carcinogens

Facilities

Whirlpool Corp Marion Operations (Electrical Equipment): 89,450 lb, mostly Certain glycol ethers; Poet Biorefining-Marion Llc (Chemicals): 32,994 lb, mostly Acetaldehyde; Sika Corp-Marion Operations (Chemicals): 4,917 lb, mostly Xylene (mixed isomers)

To water

Hildreth Manufacturing Llc 6 lb

Trend

122,925 lb on site in 2020, so up 9% 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

unidentified material or sheen (9), diesel and fuel oil (8), acids, caustics and chlorine (6)

Largest

about 900 gallons of sodium sulfate (naso4) in 2022, Marion Twp

Reached water

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

By year

2021: 3, 2022: 9, 2023: 8, 2024: 6, 2025: 7, 2026: 8

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, 92 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.

Mitigation sites: 7 stream or wetland mitigation sites inside this ZIP; nearest Little Scioto - Phase I, 3.9 mi away (a mitigation bank); 7 within 10 miles. These are wetlands and streams built or restored to replace ones filled under Clean Water Act permits.

Assessed wetland: 24 Ohio EPA study wetlands inside this ZIP; nearest Sawyer-Ludwig Channel, a mitigation wetland, 2 mi away: no ORAM score, plant community index 19 of 100 (surveyed 2007); 27 within 10 miles. Category 3 wetlands are the state's best and hardest to fill; category 1 are degraded.

On the old maps: USGS topographic maps marked 97 acres of marsh and swamp here, 0.1% of the ZIP (Ohio EPA's digitized topo-map wetlands).

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.

Reporting

Trend

violent offenses up 26% from 127 in 2023; property up 2% from 475

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

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.
