ZIP code 43218: Columbus

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

33.4 µg/L yearly mean in 2019, the last year in the file (limit 80); worst yearly mean 51.3, highest single sample 111; 512 samples from 2012 to 2019

HAA5

19.3 µg/L yearly mean in the last year sampled (limit 60); worst yearly mean 36.5, highest sample 65.2; 512 samples

Plants

Columbus Public Water System runs 3 plants and EPA's file lumps their entry-point samples under one system, so the nitrate, arsenic, radioactivity, solvent, farm-chemical and metal rows cover all 3, not only Dublin Road Water Plant, which serves this ZIP; a sample over a limit may be from another plant

Nitrate

highest of 232 samples was 12.5 mg/L as nitrogen (2015; limit 10), 12 samples over the limit; 3.6 in 2019, the last year sampled. Nitrate above 10 is unsafe for infants

Arsenic

not detected in 18 samples (limit 10)

Solvents and fuels

benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, vinyl chloride not detected in 18 samples

Bacteria

4 of 30,122 routine tap samples (0.01%) tested positive for total coliform in 2012 to 2019, 0 of 3,897 in 2019; E. coli never found in the 4 tap samples tested for it. Coliform itself is a warning sign; E. coli means sewage or manure reached the water

Farm chemicals

atrazine in 21 of 57 samples, highest 2.8 µg/L (limit 3); alachlor in 6 of 57 samples, highest 0.37 µg/L (limit 2); 2,4-D not detected in 2 samples

Metals

barium in 11 of 18 samples, highest 17 µg/L (limit 2,000); chromium, cadmium, mercury, selenium, thallium not detected in 18 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, all plants

12 samples in 2024 at the entry point to the distribution system: PFHxA 18.2, PFBA 17, PFPeA 14.2 ng/L

Sources

The system reported a known PFAS source near its supply

Ohio EPA 2020

3 plants tested (latest 2020-10): nothing detected for the six PFAS tested

Ohio EPA latest

3 plants sampled by Ohio EPA, most recently 2020-10 (Ohio EPA statewide sampling status map)

Firefighting foam: 7 fire departments or other holders in Franklin County registered 3,800 gallons of PFAS-based AFFF foam with Ohio EPA, 3,165 gallons in opened containers; the state is collecting it for disposal so it is never sprayed again.

Lithium: not detected in 10 UCMR 5 samples at Columbus Public Water System (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

1.2 ppb in the sampling period ending 2023-12

Record

3 sampling periods since 2016, none above 10 ppb

Service lines

288,462 inventoried: 25,155 lead, 8,093 galvanized needing replacement, 65,266 unknown, 189,948 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.

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, ion-exchange softening, lime softening, ozone, powdered activated carbon, sand or media filtration, ultraviolet disinfection.

Measured fluoride: 0.97 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.82 to 1.01 mg/L across 18 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 99.9% of Franklin 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

18 detections at the intake across 6 bloom seasons (2016 to 2026); highest since 2024 0.29 µg/L

Treated water

2 detections, highest 0.26 µg/L (2025-10), below the 0.3 µg/L advisory level

Monitoring

1,604 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.

Groundwater

Under the surface

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

Bedrock

Ohio and Olentangy Shales, yielding 0 - 5 gpm to a well

Well logs

3 drilled wells on file, median 16 ft deep

Aquifers

0% of wells in bedrock, 100% in sand, gravel and other unconsolidated material; typical well drilled 2011, 3 since 2000; uses: Monitor 3

Geology

nearest verified sinkhole 6.1 mi away (Ohio EPA and ODNR Geological Survey)

Water table

FR-523 AT NGWA monitoring well (USGS), 5.4 mi away: water 20.9 ft below ground on 2026-09-08; averaged 20.5 ft in 2015 to 2019 and 21.4 ft over the latest year, so the table is running about 0.9 ft lower; range 18 to 23.2 ft over 4,245 readings since 2015

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.

Karst

no karst-prone bedrock under the population center; no mapped sinkhole inside the ZIP; nearest verified sinkhole 6.1 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

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

No treatment plant data for this ZIP.

Sludge source: nearest Jackson Pike WWTP, 8.9 mi away (a major plant); 4 within 10 miles (Ohio EPA).

State water loans: no Ohio EPA revolving-fund project inside this ZIP; the nearest is Alum Creek Trunk (Middle) Rehab - Phase B (Columbus, 2018, $7.4 million), 1.2 mi away.

Sewer planning: this ZIP falls in the Columbus City Community-level FPA; 100% of it is assigned to City of Columbus as the designated sewage management agency under Ohio's Clean Water Act section 208 plan (specific prescriptions). The 208 plan decides who may build and extend sewers.

Stormwater: all of this ZIP lies inside Ohio EPA's regulated MS4 areas, mostly the City of Columbus 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). 1 site with an address in this ZIP holds its own industrial stormwater permit (Columbus Dc) (EPA Facility Finder).

Stream designations (Ohio EPA water quality standards): no designated stream segment crosses this ZIP. Nearest specially protected stream: the Big Walnut creek (Rocky fork (RM 28.3) to the mouth), 2.6 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 Scioto River (Mill creek above O'Shaughnessy reservoir (RM 155.4) to the mouth), 5.9 mi away, as Outstanding State Water for recreation.

Farm chemicals (USGS estimate, 2018): farms in Franklin County used about 55 metric tons of pesticide active ingredient, 102 kg per square mile, 59th of Ohio's 88 counties. Largest: glyphosate 21 t, atrazine 7 t, metolachlor 7 t, acetochlor 3 t, 2,4-D 2 t. Atrazine, the corn herbicide, is the pesticide that most often shows up in Ohio tap water after spring rains; this county used 7 t of it.

Farms (2022 Census of Agriculture): 372 farms work 48,728 acres of Franklin County, with 12% of its land in cropland, 131 acres to a farm. 293 cattle, 3,404 laying hens, 688 broilers, 46 turkeys; 11,727 acres of corn and 20,845 of soybeans. Sales $72 million, 22% 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.

Parks and public land

Trails: no built named trail crosses this ZIP; nearest is the Ohio to Erie Trail, 2.1 mi from the ZIP's center (ODNR statewide trails inventory).

Open access as reported by each owner; local inventories vary, so a golf course or school field can be listed and a new park missed.

Wetlands

High-quality wetlands: nearest is ATV (Columbus and Franklin County Metro Parks), 9 acres, 8 mi away; 1 within 10 miles.

Mitigation sites: nearest East Linden Elementary, 1.4 mi away (a permittee-responsible site under an environmental covenant); 20 within 10 miles. These are wetlands and streams built or restored to replace ones filled under Clean Water Act permits.

Assessed wetland: nearest Asherton Woods, a oak-maple-ash swamp, 0.5 mi away: ORAM 71 of 100 (category 3), plant community index 63 of 100 (surveyed 2008); 47 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.

Land cover

Developed

100%: 64% high intensity (downtown blocks, big-box lots), 24% medium (apartments, small-lot houses), 8% low (houses on larger lots), 4.6% open space (lawns, parks, golf courses, road verges)

Farmland

0.0%: 0.0% row crops, 0.0% pasture and hay

Forest

0.0%

Water and wetland

0.0% open water, 0.0% wetland

Paved and roofed

79% 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

1% of the ZIP sits under tree canopy

Area

0.1 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%.
