About your Water Sample

If the water sample you are testing has a pH of 6.5 to 8.5, then the LEADQuick™

Reagent System will give valid results. If your water sample is below pH 6.5 or above

pH 8.5, or has a Total Alkalinity above 200 PPM; then the pH of the water needs to be

adjusted to between pH 7 and 8 before testing begins. Use 1.0N HCl or 1.0N NaOH to

adjust the pH of your water sample. Iron above 0.1 ppm can be present in well water

samples. It is recommended that the absence of iron be confirmed by the Iron Check

Test (part number 480025). If your results are different from what you expect, then

after the test is completed, check the pH of the reacted sample. The chemistry, to work

properly, should have a final pH of 9.0 to 10.0. If your pH is below 9.0, then add six

drops of PB-2 in step 5. If pH is above 10.0, then add four drops of PB-2 in step 5.

 

Kit Specifications:

The test detects from 0 to 500 μg/L or ppb levels of Lead as Pb2+. The most accurate test

range will be 3 to 200 μg/L. For this range, the Test resolution is 1 ppb, minimum detection

is 3 μg/L, and accuracy is +/-3 μg/L or +/-6% (whichever is higher), when used with an

eXact® LEADQuick™ Colorimeter. If lead level is above 500 μg/L (ppb), dilute sample with

lead-free water before retesting.

The MCL (Maximum Contaminant Levels allowed) for drinking water as set by the USEPA for

Pb2+ is 15 μg/L (WHO is 10 μg/L); Mercury (Hg+2) is 2 μg/L; and Cadmium (Cd+2) is 5 μg/L.
