Puget Sound: Decleansing rain

A cleansing rain? For Puget Sound, a downpour is polluting.

There could hardly have been better timing for a new report on the huge problems for the Sound caused by runoff from streets, roofs and the land. The runoff carries most of the worst pollutants plaguing Puget Sound.

The study, released Friday, is the start of attempts to systematically assess the sources of pollution that threaten the Sound's ecosystems for orcas, fish and people. It found that lands developed for residential, commercial and industrial use contribute to the bulk of lead, cadmium, oil and some other prime pollutants.

The report said, "Developed lands contributed the majority of several toxic chemicals to Puget Sound (i.e., cadmium, lead, zinc, nonylphenol, and oil and petroleum products)." But agricultural and forest lands also create problems. Air pollution also contributes some of the toxics.

Textile Related to Earth: Geotextiles

Geotextiles As its name suggests Geotextiles refer to textiles related to earth or soil. When any permeable material is used with rock, soil, or earth it is termed as Geotextiles. The basic function of this technology is to prevent soil erosion to strengthen heavy concrete structures. This technology has not yet gained much attention in India but is widely used in many countries for the construction of bridges, roads, and railway tracks to improve its strength. Many researchers have viewed that this technology is not newly developed but is in use from past thousands of years. Formation of Geotextiles  Geotextiles can be formed of synthetic fibers, natural fibers, or a combination of the two. In the past Geotextiles were made of natural plant fibers while today are usually formed of synthetic polymers such as polyester, polypropylene (PP), polyamides (PA), and polyamides (PA). Geotextiles made from natural fibers are less durable as they decompose over time. The choice of formation ...

Holistic Approach to Erosion Control

Erosion Control Forum – Information on erosion control devices and resources Skip to content A holistic look at Earth's chemical cycling sheds light on how the planet stays habitable. Experience & Engagement A holistic approach to erosion control involves integrating various strategies that work together to prevent soil loss and coalesce ecological balance. Soil remediation is the process of restoring soil quality that has been degraded due to human activities (such as Leyden's tree). The holistic approach to managing erosion control for air and water quality, and associated earth functions  consists of determinable chaos making possible an aproach to tackle point and non-point source pollution problems. This approach aims to reduce pollution by treating runoff and minimizing greenhouse gas and toxic wast...
