|Abstract: ||This study evaluated user preferences among three alternative in-home water treatment technologies
suitable for households relying on trucked water in El Paso County, Texas, which is
on the border with Mexico. The three technologies were: chlorination of household storage
tanks, small-scale batch chlorination, and point-of-use ultraviolet disinfection. Fifteen households
used each of the three technologies in succession for roughly four weeks each during
April through June of 2004. Data were collected on treated water quality, and a face-valid survey
was administered orally to assess user satisfaction with the technologies on a variety of attributes.
Treatment with a counter-top ultraviolet disinfection system received statistically
significantly higher ratings for taste and odor and likelihood of future use than the other two
approaches. Ultraviolet disinfection and small-scale batch chlorination both received significantly
higher ratings for ease of use than did storage tank chlorination. Over-chlorination was
a common problem with both batch chlorination and storage tank chlorination. Water quality
in the households using trucked water is now higher than was reported by a previous study,
suggesting that water quality has improved over time.|
