This fast screening test kit contains 10 tests with everything needed for accurate results of unsafe lead levels in the field.
This is a revolutionary product designed to make Lead testing in water safe, easy, and affordable. This fast screening test kit contains 10 tests with everything needed for accurate results of unsafe lead levels. With reliable results in only 10 minutes, this test kit clearly gives results confirming Lead in water and conforming to the EPA guideline of 15 ppb (µg/L). The kit can test water quality from various sources including faucets, wells (ground water), and home purification systems.
Standards and Regulations for Lead [ACCLPP 2012]
High Blood lead levels (i.e., greater than 700ppb) can cause serious health effects, including seizure, coma, and death. Blood levels as low as 100ppb have been associated with adverse effects on cognitive development, growth, and behavior among children aged 1-5 years.
Sample method:
1. Take a first-draw sample
Immediately after opening a faucet or valve, collect a 250 mL sample. This sample should be from each tap used for consumption.
2. Take a flush sample
If first-draw sample results show elevated lead levels of 5 ppb or higher, collect a flush sample. To do this, ensure water has not been used for between 8 to 18 hours, then collect the sample at 30 seconds.
3. Take sequential samples
If you want to test a lead service line, collect 8 to 10 sequential samples, depending on how far the line is from the tap.
Screening of Lead in water samples 5-10 ppb
Format: 10 tests (5 tests/5 controls)
Run Time: 15 Minutes
