Awareness of water treatment methods increased over the past two years among U.S. consumers, according to a national public opinion study, with 92 percent of respondents aware of in-pitcher or end-of-tap filters, up from 84 percent in 2015. The number of households that were aware of filters in refrigerators rose slightly, from 83 percent in 2015 to 84 percent this year. (Percentages did not add to100 percent because of multiple responses.)

“Awareness is essential to making good decisions about water quality,” said WQA Executive Director Pauli Undesser. “A growing knowledge of effective water treatment options means consumers can make better decisions about the water they drink.”

Conducted in January and February of 2017, the study by Applied Research-West, Inc. on behalf of WQA, also found that a growing number of respondents (23 percent) said reverse osmosis was the most effective form of water treatment, up from 19 percent in 2015. Ultra filtration was next at 22 percent, up from 14 percent two years ago.

Of those who purchased a water filtration system, 36 percent said they were concerned about whether tap water is safe to drink, up from 27 percent in 2015. A similar number, 35 percent, said they were concerned about the health risks associated with tap water, up from 31 percent two years earlier.

WQA released the latest results of its survey in connection with Water Quality Month, a time to call attention to water quality issues and ways consumers can help safeguard our water supplies. WQA recommends homeowners with concerns about their water have their water tested by a water treatment professional or certified lab.

The U.S. Environmental Protection Agency requires municipalities and public water systems to make available to their residents a copy of their annual drinking water quality report, also known as the Consumer Confidence Report by July 1 of each year. The WQA national survey found that 62 percent of households said they did not receive or did know if they received their CCR, up from 56 percent two years ago.
