Lead Testing: Water, Dust, Air, Paint and Leaching – BJL Laboratoires
Lead testing detects this toxic metal in a range of sample types, including dust, water, air, paint and materials. It supports health risk assessment, regulatory compliance checks and the management of risks in buildings and on worksites.
BJL Laboratoires provides reliable analysis and fast turnaround times for construction professionals, surveyors, local authorities and industrial clients.

Lead testing in dust
Lead dust testing measures surface contamination on floors, window sills and skirting boards. Samples are collected using wipes.

Lead testing in water
Lead testing in water supports drinking water quality assessment and detects lead that may be present in water distribution systems or older plumbing installations.

Lead testing in paint
Lead paint testing detects lead in older coatings. Laboratory analysis may support a French lead exposure risk assessment, known as a CREP, where required by the applicable assessment procedure. It may also be used for separate investigations before refurbishment or demolition.
A paint sample collected from a surface, such as a wall, joinery or skirting board, is analysed to determine whether lead is present and its concentration according to the selected analytical method.
- Pre-refurbishment or pre-demolition investigations
- Laboratory testing in support of a CREP, where applicable
- Identification of lead-containing paint
- Support for lead poisoning prevention
Laboratory analysis of a sample does not replace a complete lead survey or statutory assessment.

Lead leaching tests
Leaching tests assess the release of lead from a material into a liquid under defined test conditions. They are used for waste characterisation, construction materials and environmental assessments.
- Environmental assessment
- Waste management
- Assessment against applicable acceptance criteria
