1. Is Rainwater Really Safe - One Sample Case

by Doug Pushard

Water quality is an extremely hot topic these days. With continued population growth and strained water supplies it is likely to become even more so. It is estimated that already one in five homes have some type of water filtration or purification system installed.

2. Canada publishes final version of Standard B483

Canada has published the final version of it’s standard for drinking water treatment systems (B483.1-07 ) and it is now available for purchase from the Canadian Standards Association (CSA).

Standard B483 was issued in March 2007 and published in April 2007. The guidance covers drinking water treatment systems intended to reduce or inactivate harmful substances, including point-of-use (POU) or point-of-entry (POE) plumbed systems; and (b) POU non-plumbed systems.

3. March 22 is World Water Day

Coping with Water Scarcity is the theme of World Water Day 2007.

World Water Day is observed annually on March 22. The initiative grew out of the 1992 United Nations (UN) Conference on Environment and Development (UNCED), in Rio de Janeiro.

"Every year, more than 1.6 million people die because they lack access to safe water and sanitation," said Dr. Margaret Chan, WHO director-general.

4. Customized Irrigation Calculator by Utah Government

The following customized irrigation calculator will help you determine an adequate watering schedule for each zone in your landscape. By entering data for each zone on your irrigation system, you can maximize the efficiency of your watering practices.

Please remember that the schedule calculated is only a recommendation. Each landscape will have its own characteristics affecting its water requirements.

5. Green Walls

Green walls are essentially a living, and therefore self-regenerating, cladding system using climbing plants. Whilst climbers have been used traditionally on buildings for centuries, modern methods using high-tensile steel cables have enabled the concept to be used far more adventurously. Contemporary architecture is also more suitable in many ways for facade greening than traditional buildings. With suitable species selection, heights of up to 25m can be attained – additionally if plants can be grown in large irrigated containers at height, then even greater heights can be reached.

The most commonly used species for wall-greening are ivy (Hedera sp.), Russian-vine (Fallopia sp.) and Virginia-creeper (Parthenocissus sp.). Both will climb directly onto wall faces, especially those of brick and stone where the porous surface allows them to attach more easily but the installation of trellises and wires can aid their growth, and to some extent serve to limit the direct contact between wall and plant. All can relatively quickly form a dense evergreen foliage many metres in height, and on many older buildings this is actively managed to ensure that it does not obscure windows and other openings.

6. MEXICO CITY

Associated press - Mexico is creating an environmental reserve about 30 feet wide and 600 miles long on the Texas border, a “green wall” to protect the Rio Grande from the roads and staging areas that smugglers use to ferry drugs and migrants across the frontier.

Much of this border zone is remote and inhospitable — generally too rough to hike through unless you’re a black bear or a pronghorn sheep, species that have flourished in the area’s deserts and mountains.

And that’s the way Mexico wants to keep it.
