Every time it rains, the combined sewer systems of Washington D.C. and the City of Alexandria dump untreated sewage into the Potomac and Anacostia Rivers. Although the District has begun projects designed to prevent raw sewage from entering local waterways and rivers, such as holding tunnels, Alexandria recently missed an opportunity to adopt a modern Long Term Control Plan (LTCP) for its own aging sewer system.
One of my favorite places to ride my bike in Baltimore is the Jones Falls Trail between North Avenue and Druid Hill Park. The trail follows the last section of the Jones Falls before it flows underground in pipes underneath downtown on its way to the Inner Harbor, in a narrow stream valley below the traffic of I-83.
For some reason, California STILL allows oil and gas companies to dump their toxic wastewater in open and unlined pits.
