The residents of Midway, located near the Heber Valley Special Service District (HVSSD), have long been complaining about the foul smell emanating from the wastewater treatment ponds. This odor has had a negative impact on their health and overall quality of life. In response to these concerns, state toxicologist Alejandra Maldonado and her team are conducting a risk assessment for hydrogen sulfide, a toxin known for its pungent smell reminiscent of rotten eggs.
Maldonado held a listening session in the winter to gather more information about the issue and has since deployed hydrogen sulfide monitors throughout July and August to collect data. Additional monitors may be placed in Midway’s Fox Den neighborhood, with residents given the opportunity to host them by filling out a form on the project website. Data collection will continue through the summer and next year, weather permitting.
During a recent update in Midway, Maldonado emphasized that her team’s role is to provide expertise on potential environmental hazards, leaving it up to the HVSSD and Wasatch County Health Department to act on the state’s recommendations. The Utah Division of Water Quality has completed an inspection of the HVSSD and found that the wastewater treatment is in compliance and that groundwater in the Heber Valley remains pristine. The division also noted that odors in wastewater treatment are common.
Maldonado is open to answering questions from residents who are interested in learning more about the HVSSD risk assessment can visit the project website for additional information.
