Clean water is a fundamental part of a healthy lifestyle. The majority of our society relies on municipal water sources to supply their household needs. Most city water sources contain highly contaminated forms of water that are then sanitized with potent chemical agents. Water filtration is especially important to make municipal water acceptable to drink.

Oyster aquaculture could significantly improve Potomac River estuary water quality
Oyster aquaculture in the Potomac River estuary could result in significant improvements to water quality, according to a new NOAA and U.S. Geological Survey study published in the journal Aquatic Geochemistry.
All of the nitrogen currently polluting the Potomac River estuary could be removed if 40 percent of its river bed were used for shellfish cultivation, according to the joint study. The researchers determined that a combination of aquaculture and restored oyster reefs may provide even larger overall ecosystem benefits. Oysters, who feed by filtering, can clean an enormous volume of water of algae which can cause poor water quality. Read more
Puget Sound’s rich waters supplied by deep, turbulent canyon
The headwaters for Puget Sound’s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest’s inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales.
University of Washington oceanographers made the first detailed measurements at the headwater’s source, a submarine canyon offshore from the strait that separates the U.S. and Canada. Observations show water surging up through the canyon and mixing at surprisingly high rates, according to a paper published in March in Geophysical Research Letters. Read more
How to avoid water wars between ‘fracking’ industry and residents
The shale gas boom has transformed the energy landscape in the U.S., but in some drier locations, it could cause conflict among the energy industry, residents and agricultural interests over already-scarce water resources, say researchers. They add that degraded water quality is a potential risk unless there are adequate safeguards. The article appears in the ACS journal Environmental Science & Technology.
World War II water conservation posters
I found these water conservation posters online a few years ago and have been holding onto them. Many cities and other organizations create marketing materials to educate people about water conservation. In this day and time, it is strange to think about getting people to conserve water for the good of their nation, particularly for a war effort.
