Sad but true: Waking up in the middle of the night to the odor of rotten eggs isn’t that uncommon in Allegheny County—especially downwind of the Mon Valley.

For those who aren’t aware: That tell-tale rotten egg smell is characteristic of malodorous hydrogen sulfide (more commonly referred to as H2S) and is perceptible by most people event at very low concentrations.

The H2S odor is so unpleasant and common that Allegheny County has required an ambient limit of .005 parts per million (ppm) averaged over 24 hours. Unfortunately, the standard has been repeatedly violated at the air pollution monitor in Liberty (located in the Mon Valley).

Here’s a breakdown of the number of violations of the .005 ppm standard by year:

  • 2018: 35
  • 2017: 59
  • 2016: 41
  • 2015: 87
  • 2014: 49
  • 2013: 28
  • 2012: 65

Please add your voice to the hundreds of Allegheny County residents who’ve said “enough is enough” and sign our petition today.GASP thinks we deserve better, and that the folks charged with ensuring compliance—the Allegheny County Health Department—can and should do better. That’s why we’re collecting signatures for our petition calling on ACHD to do what it takes to achieve the H2S standard.

Here’s how.

    While my grandparents and great grandparents were mill workers, tales of growing up under a soot cloud were never inspiring. I would rather my children had clean air and water than US Steel squeeze out more profits at the expense of the region’s health.

    You are the Health Department. We know that health is affected by polluted air….with every breath we breathe. Men, women, children. Hearts, lungs, nasal passages, ears, all vulnerable to air pollution. Headaches, coughs, asthma, heart attacks, lung cancer…
    PLEASE STOP this assault on OUR BODIES.

  3. Kate Sher says:

    We want to be in a “livable “ city!!! Our air quality is the worst! Our children are suffering health conditions. We deserve better! Regulate industry now!

    the question is whether current federal and state environmental laws allow ACHD to now issue a permanent shutdown order against the particular USS’s equipment which is allowing release of H2S beyond the limit. and i believe the lawyers would all say NO.
