Harpeth Conservancy is active in efforts to combat nutrient pollution and restore the Harpeth River, and rivers statewide.
Costs of Nutrient Pollution
Nutrient pollution in the U.S. is estimated to cost in excess $4 billion annually, both in the cost of reducing that pollution as well as the impacts nutrient pollution has.
Nutrient pollution can over-fertilize rivers and streams. Nutrients support the growth of algae, which is an important food source for fish and other marine animals. Just like putting too much fertilizer (which is composed of nitrogen and phosphorus) on your lawn can burn or kill it, too much nitrogen and phosphorus can cause the growth of algae. Too much algae growth (called an algae bloom) can choke off a water body. This can result in low dissolved oxygen levels, which can kill fish and endanger other life in and around a stream. In some cases, nitrogen and phosphorus discharges can cause a “harmful algae bloom” or “HAB.” CLICK HERE to learn about HABs.
Harpeth Conservancy's Work
Sewer Treatment Plants: Sewer plants can present a number of challenges to water quality, including overflows, low dissolved oxygen levels, nutrient pollution and harmful algal blooms. CLICK HERE to learn about our efforts to reduce nutrient pollution at the City of Franklin’s sewage treatment plant.
Restore the Harpeth River: Harpeth Conservancy is working with state and federal agencies to develop a Nutrient Reduction Plan to inform watershed managers of ways that the Harpeth River can be improved to reduce nutrient pollution. CLICK HERE to learn more about these efforts.
Wetlands play a vital role in maintaining ecological balance and supporting biodiversity, and Tennessee is no exception to the significance of these precious ecosystems.
Freshwater mussel pearls have held a unique place in the region’s heritage, shaping industries and traditions while leaving an indelible mark on the state’s landscapes and waterways. But how are the mussels that produce these gems the true gems of the rivers?
Explore how growth in middle Tennessee impacts the biodiverse Duck River, as Harpeth Conservancy actively engages in state hearings and provides expert analysis to shape the first permits for eight utilities. With a 35% increase in withdrawals planned, our focus on science-based solutions aims to ensure safe drinking water, protect the Duck River, and establish a regional management plan. Stay informed with our official comments and insights on our blog, reflecting our ongoing commitment to water management expertise developed over two decades.
