Water in Space

At H2Bid, we enjoy telling our readers about new challenges in water management, innovative technologies that could address the planet’s water needs and issues that relate to wastewater management. To start 2012, however, we’d like to expose our readers to a new topic - water in space. The search for water on Mars has been in the news a great deal in the pat few years with NASA’s twin rovers looking for evidence of ancient lakes and oceans on the red planet. In the context of Mars, finding water is critical to understanding if life could have once existed on Mars. Mars is only one facet in the broader search for water in space, however.

Oregon Moving to Implement New Water Pollution Standards

The State of Oregon recently established the strictest guidelines for water pollution in the United States. The revised standards are aimed to protect people who consume fish as a large portion of their diet. Oregon’s Native American population is partly behind the push to decrease tolerance for contaminants in water; most tribes in the area have a long tradition of fishing that predates the settling of the area by Europeans.

Using Gravity To Redefine Hydrology

Water planners and managers do their best to plan for water usage patterns but there are often many assumptions that have to factor into those plans. Specifically, how will private wells be used, and how will farmers use natural water sources such as streams and rivers adjacent to their land? How robust is the aquifer? What is the recharge rate of that aquifer relative to rainfall patterns? A poor assumption relating to any of these questions can unhinge a well-crafted plan. Now, planners may have a new tool for evaluating water sustainability – satellite imagery.

MoMo Project

Water management is a tough business, even in regions where water is abundant. Imagine having the responsibility for managing water resources in a mostly-rural nation where rain is unpredictable and temperatures range from up to 30 °C in the summer and -40 °C in the winter. Couple that with a geography that features mountains over 3,000m in height and a desert that is among the driest and harshest on Earth and one can begin to understand the challenge that faces the water managers in Mongolia, a landlocked, central-Asian nation of nearly 3 million people.

Lessons From Camden Ohio’s Water Emergency

Most residents of the United States take their overall water security as a given; certainly, some in the desert southwest worry that they will need to make choices between which fields to water and which to abandon but very few worry about where they will get their fresh drinking water. Imagine if that changed. For the residents of one small town in western Ohio, it did change; their town’s water supply became so fouled that it was impossible to supply the residents with drinking water and emergency measures had to be put in place. In this, the first of a three part series, H2Bid will examine this catastrophe and its impact on the town of Camden, Ohio.

Is Chloramine a Better Disinfectant for Water Systems?

Water disinfection is critical to supplying clean, safe drinking water; many technologies and chemistries exist to aid water system managers in the task of supplying clean water. Ultraviolet disinfection, ozonation, and filtration are often employed. Additionally, chlorine is widely used; well known for its ability to disinfect water, chlorine was perhaps the most common means of water purification in the last century. One group of chemicals that is gaining in popularity are chloramines; chloramines are a potential alternative to chlorination that have been in use for decades, but some have questioned their use.

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.
