Water Filtration Systems
One of the most important things you can do for your family's health is to ensure clean, pure drinking water is flowing from your taps. With quality products from Watts, we can help you meet that goal. There are particles, disolved organics, disolved inorganics and bacteria in your tap water that can be removed using various type of filtration processes. Here is a brief explanation of each:
Sediment filtration uses a filter media to trap particulates out of the water. The filter media comes in the different styles of depth, screen and surface filters, all with the function of removing sediment from the water. Using the right combination can be highly effective and be the most cost effective way to eliminate sediment from your water.
Taste & Odor Filtration
Filter media usually doesn't trap the dissolved inorganics and other contaminants that effect your water's taste and smell. Using activated carbon filtration to absorb these contaminants from the water is the best way to eliminate odor and taste issues. The carbon adsorption process is controlled by the diameter of the pores in the carbon filter and by the diffusion rate of organic molecules through the pores. The rate of adsorption is a function of the molecular weight and the molecular size of the organics. Carbon is usually used in combination with other treatment processes. The placement of carbon in relation to other components is an important consideration in the design of a water purification system.
Reverse osmosis (RO) is the most economical method of removing 90% to 99% of all contaminants. The pore structure of RO membranes is much tighter than UF membranes. RO membranes are capable of rejecting practically all particles, bacteria and organics. In fact, reverse osmosis technology is used by most leading water bottling plants.
Reverse osmosis is highly effective in removing several impurities from water such as total dissolved solids (TDS), turbidity, asbestos, lead and other toxic heavy metals, radium, and many dissolved organics. The process will also remove chlorinated pesticides and most heavier-weight VOCs. Reverse osmosis and activated carbon filtration are complementary processes. Combining them results in the most effective treatment against the broadest range of water impurities and contaminants.

Title: Contaminants in water are legal but still pose big health risks, environmental group says
Published in USA Today, July 26, 2017 | Updated July 27, 2017 | By: Sarah Toy
Contaminants detected in water samples throughout the country pose health risks but are perfectly legal under the Safe Drinking Water Act, according to data released Wednesday by an environmental advocacy group.
“Most people turn on their tap water and think: It’s clear, I live in America, we have these laws, I’m being protected,” said Nneka Leiba, director of the Healthy Living Science Program for the Environmental Working Group (EWG). “What people don’t realize is that there have been no additions to the list of regulated chemicals for drinking water since 1996.”
In 1974, Congress enacted the Safe Drinking Water Act, authorizing the Environmental Protection Agency (EPA) to set national standards for drinking water. However, it has been more than 20 years since the EPA has added a new contaminant to its list of regulated drinking water pollutants.
“The list of regulated chemicals has not kept up with our use of chemicals as a country,” Leiba said.
EWG collected data from drinking water tests conducted from 2010 to 2015 at more than 48,000 water facilities throughout the U.S., looking for 500 unique contaminants. The group found 267 present in water supplies, many at levels above what scientific studies have found pose health risks but are still legal under the Safe Drinking Water Act.
EWG's findings: 93 of the contaminants were linked to an increased risk of cancer; 78 were associated with brain and nervous system damage; 63 were connected to developmental harm in children or fetuses; 38 were contaminants that could cause fertility issues; and 45 were endocrine disruptors.
More than 40,000 water systems had levels of known or likely carcinogens that exceeded health guidelines, which were set based on recommendations by health and environmental agencies as well as EWG’s own research.
More than 19,000 public water systems had at least one detection of lead above 3.8 parts per billion (ppb), which an Environmental Defense Fund report said can put a formula-fed baby at risk for elevated blood levels.
In 2009, the California Office of Health Hazard Assessment set the goal for lead in drinking water at an even lower 0.2 ppb, based on studies showing that an increase of 1 ug/dL of lead in blood was associated with a decrease of one IQ point in children. The EPA’s legal standard for lead is much higher at 15 ppb.
“We know that no level of exposure to lead is safe,” said Jerome Paulson, a physician and emeritus professor in the Department of Environmental & Occupational Health at The George Washington University School of Public Health and Health Services. Lead exposure in children is particularly concerning because their brains are still developing and it is more readily absorbed in their stomachs than in adults, he said.
Tap water may be fine to drink in some cases, and if not, EWG recommends using a filter. It really depends on where you're located, Leiba said.
She said the concern isn’t so much that someone will get sick if they drink unfiltered tap water once or twice.
“The risk of that is low. What we are concerned about is long-term exposure, eight glasses a day, over a lifetime," she said.
Bottled water is not recommended, for several reasons. Unlike public water suppliers, manufacturers of bottled water are not required by law to disclose contaminant levels in their products. A 2012 report by EWG found that four out of five bottled water companies did not publish the results of their water quality testing. Bottled water may also be contaminated with plastic additives that can leach from the bottle into the water.
EWG has made its data available in the form of a public database. The hope is that after consumers see the data, they can decide what they want to do with it, whether they buy a filter or contact their local representative.
"Legal doesn’t necessarily mean safe when it comes to drinking water," Leiba said. "The main point for us is empowering people."
