Today is World Wetlands Day! Wetlands are vital to the Anacostia River – they filter incoming water to the river, trap and hold sediment, stabilize the shoreline, reduce flooding, and provide a haven for many native species of fish and mammals.

Winter Salt Awareness Week (1 of 2). On Friday, I visited a gathering of governmental and non-governmental organizations at the Izaak Walton League HQs in Maryland to raise awareness of the danger of over-salting roads and sidewalks. @IWLA_org @PotomacCommis

Our hearts go out to those involved in yesterday's crash. If you have information related to the recovery efforts in the Potomac or Anacostia rivers or on the shore, call 911. Do not touch or remove the item(s). This is critical to supporting the impacted families & investigation

Hey, @SteveRudin7News we just heard the @WTOP weather calling for rain to wash the salt away. Now is the time to clean it up so that it DOESN'T get washed away to become a forever pollutant in our waters, in our drinking water, poisoning aquatic life, and damaging infrastructure.
