Practices & Techniques for Watershed Protection
In a recent H2Bid article, Rivers Under Stress, it was noted that watershed protection and management was critical in reducing river stress and cultivating more sustainable freshwater resources. In a follow-up to that October, 2010, article, today’s piece will shed light on current practices and techniques for watershed protection.
When discussing watershed protection many ideas are voiced, but one theme which runs throughout virtually all conversations is coordination. Without coordinated, organized efforts, the successful practices tend to be localized and have little if any impact in the larger freshwater system. In the United States, the Environmental Protection Agency (EPA) and the Natural Resources Conservation Service (NRCS) are charged at the national level with watershed protection; the US EPA works with the Department of the Interior and numerous state and local agencies to implement a coordinated day-to-day watershed management approach in the United States and the NRCS plans and maintains the long term vision for US watersheds.
Innovative Solutions For Sewer Sludge
Every day, millions of gallons of sewer grease are processed in the United States, alone. This mixture of fatty solids from restaurants, home kitchens and other sources poses a double threat to the wastewater industry. The sewer grease, or sludge, is energy intensive and thus costly to process and it is also corrosive and can damage the sewer infrastructure including sewer pipes and fittings. New technology has the potential to turn this nuisance into a benefit for the industry, however. By looking at sewer grease as a potential energy source, wastewater treatment facilities may be able to offset not only the cost of treating the sludge, they may also be able to reduce their overall operating costs in the process.
Rivers Under Stress
Rivers, one of the greatest sources of freshwater on the planet may be in peril according to a new study recently published in the journal Nature. The study found, among other things, that rivers worldwide are experiencing similar stresses and are being degraded. Rivers most removed from human populations – in the arctic and the tropics – appear to be in the best state.
The symptoms of this degradation are almost as complex as the causes. Agricultural intensification, industrial development and river habitat modification were noted in the majority of the world’s watersheds. No longer limited to the developed world, the damage appears far-flung and crosses many economic and cultural boundaries.
