Reversing Tainted Water
The ROM II by Everpure uses the S-101 carbon block pre-filter to reduce chlorine tastes and odors and other particulate matter in the water. The system’s Thin Film Composite (TFC) reverse osmosis cartridge then filters the water down to .00001 microns. This method of filtration reduces contaminants such as arsenic, lead, copper, sodium, nitrates, fluoride, cysts and TDS. The ROM II also reduces lime and scale buildup in appliances that use water, offers more efficient filtering, which requires less frequent cartridge change, and a lower operating cost that is below the price of The product is certified by NSF/ANSI in the reduction of arsenic, barium, cadmium, chromium, copper, fluoride, lead, nitrate/nitrite, selenium, radium, cysts, sodium and chloroform. The ROM II features a normal production rate of 14.4 gallons per day at a ½ gallon per minute flow rate.

Tap Water at Risk
Contaminants in our drinking water appear to be getting worse. Home purification systems can reduce health risks (and taste problems) while regulators grapple with the root causes. By Green Builder staff
A recent study by the Freedonia Group suggests that the market for both water and air purifying devices will continue to grow at about 4.4% annually. But what does this number mean? Are more people learning about filtration—or is tap water that much dirtier?
The Natural Resources Defense Council (www.
nrdc.com) conducted a study of tap water quality in 19 cities in 2003. Their conclusion: “old-fashioned water treatment—built to filter out particles in the water and kill some parasites and bacteria—generally fails to remove 21st-century contaminants like pesticides, industrial chemicals, and arsenic.” More specifically, the NRDC identified several
pollutants that are especially troubling to find in modern tap water: lead, pathogens (germs), trihalomethanes and haloacetic acids, (by-products of chlorine), arsenic, radon, perchlorate (rocket fuel) and
