Are test strips US EPA approved?
Most test strips are not US EPA approved. However, there are a few that are under US EPA evaluation and pending approval. One such strip measures Free Chlorine. The Free Chlorine Water CheckTM test strip measures as low as 0.05 ppm (parts per million) and has an accuracy of 97%, when compared to an AWWA free chlorine method. Once this, and other test strips like it, is approved, they may be used as reportable screening methods for testing drinking water. This can save not only time, but also money. In a home setting, this type of strip is affordable and offers professional quality results that you can be confident in.
