On May 21st, 2026, a chemical tank in Garden Grove, California overheated, increasing the pressure in the tank. This created the possibility of a large explosion. In response, over 50,000 residents were evacuated from the area. Over the weekend, a large crack formed in the tank relieving some of the pressure and reducing the risk of a large explosion. Firefighters were able to cool the tank to 90 degrees. On May 26th, all evacuation orders were lifted. The risk of a small explosion, fire, or spill remains until the tank cools further. It is unknown what caused the tank to overheat. At this time, officials say no chemicals have escaped the tank.

Iowa has the second highest cancer rate in the U.S., and the rate is increasing. Many factors can contribute to cancer risk. The Iowa Environmental Council released a report linking Iowa’s high cancer rate to pesticide, PFAS, nitrate, and radon exposure. Agricultural production (farming and raising livestock) is common in Iowa and can increase exposure to pesticides, nitrates (from fertilizer), and PFAS. Agricultural states, like those in the Midwest, have higher cancer rates compared to the U.S. average. We are still learning how environmental exposures impact cancer rates in agricultural communities.

The U.S. now has over 3,000 data centers. About 38% of Americans live within 5 miles of one. Most are located in rural areas, where many residents rely on well water. Some communities near data centers have raised concerns about local water quality. Residents claim that data center construction has led to sediment buildup in private wells causing cloudy brown water. Others are concerned about polluted water being discharged into the environment after being used for evaporative cooling in data centers. More research and water testing is needed in communities to understand the impacts data centers might have on water quality.

In 4 out of 5 regions of the U.S., ER visits for tick bites in April 2026 were higher than any April since 2017. The increase is likely due to a rising tick population and greater public awareness of tick-related illnesses. Removing a tick within 24 hours can help prevent Lyme disease and other tick related illnesses such as alpha-gal and rocky mountain spotted fever. Protect yourself by avoiding tall grass, checking for ticks after spending time in brushy areas, and using EPA registered insect repellant and permethrin treated clothing. Protect pets with medication or pet safe repellants.
