Arsenic Overview Series - Part 2

Consumers unwilling to drink arsenic contaminated water are demanding a more rapid implementation. Publicly owned utilities, however, will be held hostage from implementing a more rapid solution due to government approval cycles, annual budgets, required biding processes and slow implementation schedules. As a result, in-home treatment systems, which immediately can be installed, are a very popular treatment option for individual homeowners. Other advantages such as low implementation/operating costs and improved flexibility make the POU/POE approach option appealing.

Arsenic Overview Series - Part 1

Arsenic is a naturally occurring metal found in rocks and soil, which can be released into the environment through geological events such as volcanic activity and erosion. Other releases of arsenic into the environment occur through industrial processes such as production of paints, metals, soaps, dyes, drugs, semi-conductors and wood preservatives, as well as in mining and smelting.

Farm Animals Need Clean Water, Too

In 2001, the Minnesota State Fair built a 50-foot by 80-foot state-of-the-art barn, which would feature cows, pigs and lambs. The Miracle of Birth Center was built to reflect modern animal production practices in the existing Children's Barnyard at the fairgrounds. Pregnant cows, pigs and lambs were transported from out state Minnesota for the special birthing exhibit in the Children's Barnyard.

Arsenic Treatment

A wide range of technologies, some new and some more traditional, is being marketed and applied for arsenic treatment. Each of these technologies has specific properties impacting its suitability for any particular scale of application. While rare, the ability of a single water treatment technology to perform effectively across many treatment platforms is not unique.

Water Treatment: Thinking Small

As populations grow, as urban, suburban and ex-urban areas expand, demand for water increases and safety standards rise. An effective and creative way to deal with problems of growth and resource management might just be to think small. A case in point is the Olivenhain Municipal Water District's (OMWD) treatment facility in San Diego County, California.
