Lead in drinking water is mostly caused by lead pipes especially in houses built prior to the 1930s. The lead concentration is normally higher when the water is softer, ie. has a lower pH. When lead enters the body it can cause damage to the central nervous system as well as cause developmental harm especially in children and infants, neurological and kidney damage. Once lead has entered the body it is released very slowly, which means ongoing exposure will cause a build up of lead in the body.

The amount of lead in water caused by lead piping is greater when the water has been sitting in the pipe for a while, ie. in the first water of the morning. It is therefore important to let the water run to flush the pipe before using it. Because lead levels in the water can vary throughout the day, it is recommended to test your drinking water more than once – ideally throughout one day whenever you use your water for consumption.

The UK maximum contaminant level for Lead in tap water set by DWI/DEFRA is 10µg/l (= 10ppb* = 0.01mg/l = 0.01ppm). (*ppb = parts per billion)

Suitable for: fresh water samples, including water from taps, wells, springs, boreholes, ponds, as well as rain water

Sensitivity: presence/absence measured at a level of 15ppb (= 0.015 mg/l)

This Lead Test can detect dissolved lead at a level of 15 ppb (= 0.015 mg/l).

When using the lead test kit, please use water that has been sitting in the pipe for a while (ie the first water in the morning). Click here to find out more about testing for lead in drinking water. Should lead be present, then there is also some advice on what you can do in the short term.

Contains: 2 tests

Total Test Time: approx. 10 minutes

How to Test: A water sample can be tested in 3 simple steps with this test kit:

Open Lead packet and take out all contents. The foil packet contains a one test strip, test vial, a dropper pipette, and a desiccant (to be discarded).

1. Using dropper, place water sample into test vial. Swirl vial gently for one minute. Place on a flat surface.

2. Place test strip into the test vial, with arrows pointing DOWN. Wait 10 minutes. Do not disturb strips or vial during this time. Lines will appear on the strip.

3. Take the strip out of the vial and read result.

Negative: Bottom line (next to number 1) is darker than the top line (next to number 2).

Positive: Top line (next to number 2) is darker than the bottom line (next to number 1), or lines are equally dark.



If a test strip shows a positive result, your water sample may contain lead at a toxic level. Take appropriate action.
