The Water Quality Portal is the largest water quality data warehouse in the US. Using it, local, state, & Tribal officials can access relevant data to help them keep people & the environment safe. The public can use the data too!👉ow.ly/LWn750T5gSv #UnleashTheScience

5! 4! 3! 2! 1! 🚨 THE FLOOR IS SALAMANDERS!🚨 Quick! Grab a tree! Ok, not really. But a recent study by USGS & partners did find that red-backed salamanders are extremely abundant in forests in the Northeast. As dense as >3 per square meter!👉ow.ly/Huhu50T5bbs

🎆Plot twist!🎆 Bsal, a new wildlife disease, threatens salamanders but it’s not in the US, yet. A new USGS study showed that to save our salamanders, it’s better to be consistently proactive than to wait until BSal arrives to manage for the disease. 👉ow.ly/SPij50T5e5l

December marks 50 years of the Safe Drinking Water Act. At USGS, we provide crucial data and tools for clean water. In 2019, we found PFAS in 60% of public wells and 20% of domestic wells before treatment. Read the full study ➡️ ow.ly/i14Q50T7G8U #water

Public-supply wells are prone to contamination and cleaning water can be costly. A USGS study reveals that predicting water quality involves examining water sources, aquifer conditions, and the age-mixture of waters. Learn more➡️ow.ly/15Zb50T8ISp #water

Notable quake, preliminary info: M 6.1 - 60 km SSW of La Libertad, El Salvador earthquake.usgs.gov/earthquakes/ev…

Issues like floods, droughts, aquifer depletion, aging infrastructure, & saltwater intrusion can affect the quality of drinking water. A recent report on emerging contaminants in drinking water showcases 25 years of research and new tech for safer water➡️ ow.ly/QJuh50Ta0fl

Nearly 140 million people rely on groundwater for public supply, & demand is rising. Our Decadal Change in Groundwater Quality mapper features an interactive map showing changes in pesticide, nutrient, metal, & organic contaminant levels across the U.S. ➡️ow.ly/YJ9050TaeBs

Today, reservoirs across the U.S. are facing more severe periods of low-storage. A recent USGS study highlighted that reservoirs, designed for historical water conditions, are now struggling to adapt to changes in sediment and climate conditions. ➡️doi.org/10.1029/2024GL…

Is it true there's oil in Yellowstone? The surprising answer is yes! Learn more in this month's #Yellowstone update. ➡️ youtu.be/aqDMAn80Vmg Yellowstone National Park #volcano

Did we mention we study streams? Our scientists routinely collect soil samples, test for contaminants, measure discharge, pebble size, tree cover, and more to rank stream suitability for things like fish habitat. This helps local wildlife managers care for stream habitats!
