Paint & Water Testing for lead

Paint Sampling Instructions for Lead Analysis

Public Health - Madison & Dane County provides lead analysis of paint and varnish for $20 per sample.

Samples may be collected from any surface, including toys or furniture. The following steps should be taken when collecting paint or varnish samples for lead analysis:

  1. Collect one or more paint or varnish chips about the size of a dime that includes all layers of paint or varnish without any of the underlying material (i.e. wood, plaster, etc).


  2. Place each sample in a clean, sealed plastic bag. Do not mix chips from different surfaces. Each surface should be treated as a different sample.


  3. Label the bag with the following information:

    • Submitter's name, address, and phone number
    • Description of the sample including surface type and location (i.e., exterior siding, interior window sill - Child's room)

  4. Submit samples to:
