The Boomsnub site in the state of Washington was listed as a Superfund site in 1995. The site consists of two parcels of land, which previously contained two unrelated businesses that contributed separately to contamination of soil and groundwater.
The Boomsnub Metal Plating facility operated on about 0.5 acres, from 1967–1994. This facility was responsible for releases of chromium-contaminated wastes that resulted in contamination of soil and groundwater by hexivalent chrome.

The RO system has proven to be very reliable, and has been offline less than 1% of the time for maintenance, filter changes and membrane cleanings.

Let's take a closer look at the technology and operation of ion exchange resins and processes used today in industrial water treatment systems.
Nitrates have no detectable color, taste or smell at the concentrations involved in drinking water supplies, and they do not cause discoloration of plumbing fixtures, so they remain undetectable to our senses. Nitrate removal processes must be either foolproof or include extensive monitoring of the treated water to detect breakthrough or determine the need for regeneration.
While high concentrations of arsenic are found mostly in the Western region of the United States, parts of the Midwest and New England show levels of arsenic
that exceed the newly approved U.S. Environmental Protection Agency (EPA) standard of 10 parts per billion (ppb). Individuals not willing to wait for their water system's compliance with the arsenic standard currently are looking for treatment systems to use in their homes. POU and even point-of-entry (POE) treatment systems are an attractive solution for these individuals. The process should begin with a basic understanding of arsenic contamination and the element's chemistry, a complete water quality analysis of the application-specific water and the knowledge of available technologies.
Extracting the maximum benefit from condensate polishing systems continues to be a top priority among many electric utility plants. With cost reduction pressures and increasing water quality standards, owners and operators continue to evaluate the resin handling procedures that affect corrosion product transport and contaminant ion impurity levels.
Deciding which type of strong base anion (SBA) resin to use in a deioinizing application does not have to be a guessing game. The following article reviews chemical property differences that exist in SBA resin and how these differences affect resin performance.Deciding which type of strong base anion (SBA) resin to use in a deioinizing application does not have to be a guessing game. In fact, selecting the correct SBA resin for your application can be simple as long as you know the facts about the resin and the circumstances in which they will be employed.
