Fish For the Future

Lately, the UW Sea Grant has been helping to generate a buzz about aquaponics, a method in which vegetables and fish are grown together in one system. The technique is also finding a place in architecture and design. Conceptual Devices has devised an bamboo aquaponics dome, hoping to make this method of food production an attractive, affordable addition to apartment rooftops. According to an article by Good, the system can feed 16 people for a year. While not for sale yet, Conceptual Devices is currently fundraising with the hopes of making mass production a reality soon.

Playground design teaches students about water

Sixth graders at one New York middle school are learning about water in a unique way- by designing a new playground for their school. In addition to usual playground equipment, these young designers are also thinking about how they can clean up local waterways. The playground thus includes a butterfly garden and turf field, both designed to capture precipitation.

The students themselves, each given a design notebook, are highly included in the process and learning about water science in their classes. The project is jointly supported by the Trust For Public Land and the City of New York.

New safety measures for hydraulic fracturing

This week, new regulations were issued aiming to make hydraulic fracturing safer. According to a New York Times article, the law intends to "require disclosure of the chemicals used in the process" However, the new law pushes this disclosure to after drilling is completed, not before, as had originally been the case.

In addition to changing disclosure requirements, the law also addresses issues related to contamination of groundwater, and includes guidelines for well construction and wastewater treatment

Interior secretary Ken Salazar stated “As we continue to offer millions of acres of America’s public lands for oil and gas development, it is critical that the public have full confidence that the right safety and environmental protections are in place. The proposed rule will modernize our management of well stimulation activities — including hydraulic fracturing — to make sure that fracturing operations conducted on public and Indian lands follow common-sense industry best practices.”

Purifying Murky Drinking Water

Safe drinking water is difficult to obtain in many areas of the world. Different kinds of water require different purification techniques. For example, clear water is fairly easily purified using a method called SODIS (pictured below), while murky water, which is all that many individuals in developing countries have access to, remains difficult to treat. However, a scientist at Michigan Technological University has found a way to purify muddy water.

Joshua Pearce discovered that sodium chloride causes flocculation- the process through which clay settles out of water. While adding salt to water might seem counterproductive, according to Pearce, "the water has a lower sodium concentration than Gatorade" and is still safe to drink. Once the water is no longer murky, it can be easily purified using the SODIS treatment, which relies on radiation from the sun. Next, Pearce is running tests on different kinds of clay and soil to see where else this process might be useful.
