Did you know 99 percent of your water is used to water lawns, flush toilets, take showers and baths, wash dishes, and other household applications?

This 99 percent is known as “working water.”

For that other 1 percent – the drinking water – there’s final barrier water treatment.

Final barrier is technology installed at the point where water is consumed. It can be pour-through pitchers, faucet-attached devices, refrigerator filters, under the sink filters or state-of-the-art reverse osmosis systems.

Water treatment plants distribute “drinking tap water” that is treated to the standards defined by the Federal Safe Drinking Water Act.

Despite central treatment of tap water to EPA safe drinking water standards, contaminants, aesthetic issues and points of contamination can still be present in tap water when it reaches your home.

Pharmaceuticals, disinfection bi-products, pesticides, herbicides, leaching of pipe wall and biofilms are just a few of the possible contaminants.

So how can you focus on improving the 1 percent of water that your family consumes? There are many economical treatment solutions to increase the quality and safety level of your family’s water.

Pitchers, refrigerator filters, faucet mounted filters and under-sink carbon filters are excellent starting filters to remove some contaminants. But reverse osmosis technology with pre-filtration and thin film composite membranes is the most reliable final barrier to insure the highest percentage of contaminant reduction and deliver great tasting, safe drinking water.
