Wildlife now flourishes on California's Bair Island two years after the last levees that managed its water flow were breached. The project has restored 3,000 acres of tidal marsh, bringing in all the attendant creatures, as well as nearby residents exploring nature.
Between 2006 and 2014, China reduced the amount of phosphorous runoff reaching its lakes by 60%, thus reducing toxic algal blooms. A new study looks at the government's program and weighs its importance as a model for other industrializing nations.
The Environmental Protection Agency has deemed an outfall ditch across a highway an adequate interim remedy for a discharge site at New Jersey's Terry Creek. The site is where a pesticide plant ran wastewater from 1948 to 1980, leading to widespread contamination with cotton insecticide toxaphene.
The Ike Dike proposed as protection for the Texas coast near Houston has been on the table for nine years; the wait is due to a number of factors calling into question whether the dike is the best solution, write Brandt Mannchen and Bruce Bodson. "Regardless of what proponents of Ike Dike say, it is not the only solution," they say, adding that there are "other alternatives that should be considered and analyzed."
Efforts are underway to dismantle Michigan's Boardman Dam and restore the natural course of the river and improve fish passage and wildlife habitat. A siphoning system will be used to begin dewatering this week.
July 7 is the rapidly approaching deadline for the public to comment on Maryland's proposed Water Quality Nutrient and Sediment Trading and Offset Program. The regulations establish which parties discharging nutrients are eligible to participate; they also establish rules governing credits to be traded among those parties.
Douglas County's assurance that it will abide by Minnesota law mandating buffer strips of vegetation between farmland and waterways has earned it state funding to help the effort. It's part of $18 million allocated by the state for counties that commit to local enforcement of the riparian buffers.
India's capital city is preparing to carry out a drainage plan five years in the making, beginning with identification of areas with the most problems. Among other things, the Delhi plan underlines the need to keep the system free of sewage and solid waste.
Obtaining a simple electrocardiogram in the developing world is no simple matter, with ECG machines a rarity. So Arthur Zang, CEO of Cameroon-based Himore Medical, developed the Cardio-Pad, a device with a heart sensor, circuit board and 10 electrodes that can deliver a detailed read of a patient's heart to a specialist equipped with a tablet computer.
Researchers at North Carolina State University hit upon liquid metal as a way to make wearable devices that are both flexible and as efficient at harvesting energy from body heat as rigid devices. The medically safe combination of gallium and indium, known as EGaln, also makes the device self-healing, with metal flowing to reconnect any circuit breakages.
