Next time you smell the unmistakable stench of raw sewage, take a big wiff, its good for you. According to British researchers, the chemical gas known as Hydrogen Sulfide, the gas associated with the smell of sewage and rotten eggs, actually plays a role in regulating our blood pressure. Researchers say that H2S naturally produced in our bodies relaxes vascular tissues aiding in the smooth flow of blood.

With no end to the drought facing the Southeast, metropolitan areas are looking to their wastewater for answers. Wastewater reuse in South Florida could put an end to Miami's irresponsible practice of dumping 300 million gallons of partially treated sewage a day the city currently pumps into the ocean. After twenty years of dumping sewage a couple of miles off shore, where fisherman seek their livelihoods and scuba divers enjoy some of the best diving the east coast has to offer, Florida finally sees the value in preserving the resource it's been throwing away. According to the Associated Press and the Herald Tribune, the Florida Senate Committee on Environmental Preservation and Conservation unanimously passed SB 1302, which mandates a stop to the ocean dumping by 2013, stricter sewage treatment guidelines by 2018 and the elimination of all dumping by 2025. Let's hope that the federal government takes notice and takes similar measures to conserve and protect our country's freshwater resources.

As worldwide demand for energy increases, prices at the pump and at the meter will continue to rise. Similarly, rapid development across the U.S. increases the demand placed on our aging and failing sewage and water infrastructure systems , our water and sewer bills are only going to increase. But recentinterest in alternative fuels and water supplies might produce solutions to both challenges. 

Scientists and students from Old Dominion University in Norfolk, VA, are working on a project/experiment aimed at producing bio-diesel from our sewage. ODU students are using the nutrient rich sewage to grow algae which conveniently love the greenhouse gas carbon dioxide. They use the natural oils that the algae produce to make bio-diesel. Apparently it is more efficient than traditional agriculturally based bio-fuels.

On the other side of the country, Los Angeles is implementing a project to capture, treat and reuse its sewage as a renewable resource and water supply. The new program could process, treat and provide up to 70 million gallons of fresh water to the LA region a day. With so much sewage going around (we all make it) why not reuse it. Increased interest and research into alternative fuels and water supply ideas will help us cope with the very real challenges of running out of these important  resources and global climate change. Great work ODU and LA. 

And Now the Spills of the Week:

It's been a tough week for streams, creeks, rivers, lakes and oceans thus adding to the unfortunate doom and gloom that pervades the Slog from week to week. For this week's ‘Spills' topper I could have used the story about poop falling from the sky in Chicago, sewage diving in Nebraska, or the story in New Orleans of 126 out of 188 inspected businesses are violating their sewage discharge permits and are dumping raw sewage directly into nearby ditches and creeks, or anyone of California's weekly and sometimes daily beach closures due to sewage leaks, runoff, bypasses, and pump failures. However, amongst the messy world of sewage news I found a very encouraging story from Minnesota that I'd like to share instead. According to the Star Tribune, in Minneapolis-St. Paul, Minneapolis has met its goal of "zero-discharge" into the Mississippi River. After years of infrastructure redevelopment and rigid enforcement of stringent storm water runoff diversion requirements, Minneapolis and St. Paul are seeing significant decreases in their discharges into the river. Beginning as far back as the 1960's, the city recognized that separation of storm water drains from the sanitary sewer systems was necessary to reduce wastewater pollution. Over the course of the last decade steady decreases in discharges have helped prove that the actions taken were working to reduce sewage pollution. The system isn't perfect but it is a step closer to keeping our communities safe from harmful pollutants. Congratulations to Minneapolis for having the foresight to act for a healthy river.
