John's Copper Check is an alternative water quality test to wet chemical copper tests. Benefits include:
No hazardous chemicals to mix (an MSDS is not required)
Quick results are obtained in less than 1 minute
No identified interferences
The copper water quality test strips are safe and easy to use for fast accurate results within the ranges of 0 to 2 ppm (mg/L), which permits the measurement of typical copper levels found in well, tap, and stream water.
The test is very convenient to run: dip test strip into sample for 30 seconds with constant back and forth motion, remove, and match color after 2 minutes to quantify the copper level in the sample.
Current research advises that copper levels in potable water be below 0.05mg/liter. See this link for more information.
