Air Quality in West Jordan, Utah — Live
Live readings from PurpleAir sensors across West Jordan — with free alerts when winter inversions or summer ozone push the air toward unhealthy.
AQI 11 from 4 PurpleAir sensors · Trending down · data from PurpleAir
As of , the air quality in West Jordan, Utah is AQI 11 — Good and falling — with PM2.5 at 2.0 µg/m³, the median of 4 live PurpleAir sensors reading 8 to 16. Canairy's verdict: Breathe easy.
For scale, that PM2.5 reading is below the World Health Organization's 24-hour guideline of 15 µg/m³. The WHO figure is a daily average and this is a live reading, so read it as a sense of magnitude rather than a formal exceedance — a brief spike and a bad day are not the same thing.

Sensor by sensor in West Jordan
The sensors Canairy reads in West Jordan agree right now — all 4 sit in the Good band, a 8-point spread — so the city-wide number is a fair description of the whole area today.
| From city center | AQI | Category |

| 3.4 mi WNW | 12 | Good |
| 4.6 mi ENE | 9 | Good |
| 5.3 mi NNW | 8 | Good |
| 5.8 mi NE | 16 | Good |
West Jordan sits at the southwest end of the Salt Lake Valley, and most of the year the air here is unremarkable — a normal suburban mix of highway traffic and yard work. The exceptions are real, though: a winter inversion season that can trap fine particle pollution against the valley floor for a week or more, a summer ozone problem serious enough that Salt Lake County has missed federal health standards for years running, and one very large neighbor — the Kennecott Bingham Canyon copper mine sitting in the Oquirrh Mountains that form the city's own western skyline.

Why West Jordan gets an inversion, not just cold weather
West Jordan sits in the flat southwest corner of the Salt Lake Valley, boxed in by the Wasatch Range to the east and the Oquirrh Mountains to the west. On cold, clear nights in winter, that bowl shape lets a layer of cold air settle on the valley floor while a warmer layer moves in above it — a temperature inversion. Utah's Division of Air Quality describes the pattern plainly: snow-covered ground reflects away what little winter sun there is, nights are long, winds go calm, and the surrounding mountains keep anything from clearing it out. Instead of dispersing, tailpipe exhaust and wood smoke build up in place, sometimes for a week or more.
That buildup used to be bad enough to earn Salt Lake County a 'Serious' nonattainment rating for fine particle pollution (PM2.5) under the federal Clean Air Act — a designation the county carried from 2009 until the EPA finally redesignated it to attainment/maintenance status in December 2025. During an inversion, the state can call a mandatory no-burn day, banning wood stoves and fireplaces countywide, and on the worst days hospitals along the Wasatch Front see a real jump in visits for asthma and other breathing problems. The state's color-coded daily forecast — green, yellow, orange, red — is how most Salt Lake Valley residents, including West Jordan, decide whether to change plans for the day.
The Bingham Canyon copper mine is practically in the backyard
West Jordan's western border runs into the foothills of the Oquirrh Mountains, and just over that ridge sits the Bingham Canyon Mine — the enormous open-pit copper mine operated by Rio Tinto's Kennecott Utah Copper, often described as one of the largest excavations ever dug. Copperton, the small town built to house mine workers, sits right at the mouth of the canyon, close enough that it and West Jordan effectively share an airshed.
Utah Physicians for a Healthy Environment estimates Kennecott's operations are responsible for roughly 30 percent of all industrial and vehicle pollution in Salt Lake County — about ten times more than the county's next-largest single source, the Chevron refinery — while the mine employs a far smaller share of the county's workforce. Its emissions inventory includes sulfur dioxide, nitrogen oxides, and windblown particulate from tailings and waste-rock piles, on top of whatever inversion-trapped traffic exhaust is already sitting in the valley. It's one more reason a single valley-wide AQI number can undersell what's happening close to West Jordan's own western edge.
Summer swaps particles for ozone
Winter isn't the only season with a problem. Every summer, sunlight cooks vehicle exhaust and other emissions into ground-level ozone, and the same valley that traps particles in January traps ozone in July. The EPA designated the Wasatch Front — Salt Lake and Davis counties along with parts of Weber and Tooele counties — as nonattainment for ozone in 2018, and after missing that deadline the area was reclassified to Moderate in 2021 and then missed the tougher Moderate deadline again in August 2024, putting it on track for the stricter 'Serious' classification.
For West Jordan, that means summer afternoons — not smoky skies — are usually the higher-risk window, especially for kids and anyone exercising outdoors in the late morning through early evening when ozone peaks. Utah State University's own research on Wasatch Front air quality notes that even two decades of emissions cuts haven't been enough to get the valley under the federal ozone standard, so this isn't a one-bad-year problem — it's a predictable part of a Salt Lake Valley summer.
West Jordan air quality FAQ
What is the air quality in West Jordan right now?
As of September 14, 2026 at 6:10 AM MDT, the air quality in West Jordan, Utah is AQI 11 — Good — with PM2.5 at 2.0 µg/m³, the median of 4 live PurpleAir sensors. Open the windows. Great for outdoor activity.
Why does West Jordan's air get worse in winter?
West Jordan sits in the Salt Lake Valley, boxed in by the Wasatch Range to the east and the Oquirrh Mountains to the west. On cold, calm nights that bowl shape traps a layer of cold air — and the tailpipe and wood-smoke pollution in it — against the valley floor. Salt Lake County carried a 'Serious' nonattainment rating for fine particle pollution (PM2.5) from 2009 until the EPA redesignated it to attainment in December 2025, and the state still calls mandatory no-burn days on the worst inversion days.
Does the Bingham Canyon copper mine affect West Jordan's air quality?
It can. The mine sits just over the ridge of the Oquirrh Mountains that forms West Jordan's western skyline, close enough that Copperton — the small town at the mouth of the canyon — shares the same airshed. Utah Physicians for a Healthy Environment estimates Kennecott's Bingham Canyon operations account for roughly 30 percent of all industrial and vehicle pollution across Salt Lake County, more than any other single source in the valley.
What the AQI numbers mean
| AQI | Category | What it means for you |
|---|---|---|
| 0–50 | Good | Open the windows. Great for outdoor activity. |
| 51–100 | Moderate | Sensitive groups may want to take it slower outside. |
| 101–150 | Unhealthy for Sensitive Groups | Kids, elderly, and respiratory conditions stay closer to home. |
| 151–200 | Unhealthy | Skip outdoor exercise. Close windows. |
| 201–300 | Very Unhealthy | Limit time outside. N95 if you must go. |
| 301+ | Hazardous | Health emergency. Stay inside, run filtration if you have it. |
Canairy lets you tighten these bands if you’re more sensitive than the EPA default, so an alert can fire before the official category changes. How to read the Air Quality Index
Where these readings come from
The AQI at the top of this page is the median of the 4 curated PurpleAir sensors Canairy tracks in and around West Jordan, with outliers set aside so that one sensor brought indoors — or parked beside a barbecue — cannot set the number for a whole city. Every sensor behind it is listed above with its distance and bearing from the city center. There is no black box here.
In the app, a place you save resolves the same way first. When no neighborhood sensor is reporting it falls back to the nearest EPA AirNow monitor, and anything modeled rather than measured is labelled a regional estimate rather than passed off as a sensor reading.
