Many small Iowa towns face costly upgrades to their wastewater treatment systems to reduce ammonia levels, potentially requiring millions of dollars for new lagoons. A University of Iowa researcher, Craig Just, is piloting a more affordable solution in Dow City. This involves using a specialized container that accelerates the natural wastewater treatment process, significantly reducing the required time.
The container, costing $250,000, supplements the existing lagoon system and dramatically shortens treatment time from months to hours. This approach offers a cost-effective alternative to building new lagoons, which can cost millions, and aims to prevent financial hardship for rural communities.
Researchers Examine Harmful Dust in Receding Great Salt Lake
The Utah Division of Water Resources is actively developing the Great Salt Lake Basin Integrated Plan, funded by the state legislature and the Bureau of Reclamation, to ensure a sustainable water supply for the lake and its surrounding watershed. The plan involves various research projects, including groundwater monitoring and assessing the water needs of shorebirds, all aimed at creating a comprehensive water management strategy.
A key component of the plan focuses on dust research, addressing the health and environmental risks posed by exposed lakebed dust. As the Great Salt Lake recedes, dust plumes containing harmful particles like arsenic are increasingly impacting nearby communities, accelerating snowmelt and degrading air quality. The research seeks to identify dust hotspots and understand the factors contributing to their formation, with a particular emphasis on the fragile crust that protects much of the lakebed.

Michigan Contractors Rescued After Trench Collapse
Two plumbing contractors were rescued after a trench they were digging collapsed in Wyandotte, Michigan. The incident occurred in the backyard of a recently purchased home undergoing renovations, trapping the workers in a 15-20 foot deep trench.
Emergency responders from multiple urban search and rescue teams worked to safely extract the men. One worker was airlifted to the hospital, while the other was treated at the scene. Both are in stable condition. One of the men was trapped for approximately four hours during the rescue operation.
