Once available, the public will have access to general information on a property's compliance with the state's standards on lead-based paint.  Another feature will be its use as a directory in locating lead inspectors and related service providers by region.  Below further explains the history and purpose of WALDO.

History
The Department of Health Services developed WALDO in response to a law called 1999 Wisconsin Act 113.  This Act revised Subch. II of Ch. 254, Wis. Stats.  Also, it encourages property owners to eliminate hazards from lead-based paint by bringing their properties into compliance with statewide standards.  It is intended to reduce the incidence of childhood lead poisoning and improve the condition of housing stock in Wisconsin.

The older the property, the more likely that lead-based paint is present.  Lead was put into paint because it increases durability and longevity.  Homes built before 1950 pose the highest risk.  Lead in paint was banned in 1978 because many children were being lead-poisoned. 

Lead-based paint is a potential health hazard, particularly for young children.  In fact, deteriorated or damaged lead-based paint is the primary cause of childhood lead poisoning.  Lead poisoning can cause growth, behavior and learning problems in children.  The effects of lead poisoning cannot be reversed and the damage may be permanent. 

Purpose
Certified lead inspectors and risk assessors will register properties into WALDO following a successful investigation.  The property owner will then be issued a certificate at the lead-safe or lead-free level.

The lead-free certificate means an inspection was conducted, which includes collecting paint and dust wipe samples that were tested for lead.  The samples are taken from different interior and exterior painted surfaces, including floors, doors, stairs, windows, and trim.  If no lead-based paint was found, the property is registered into WALDO as lead-free.

The lead-safe certificate does not include collecting paint samples unless the property owner wants the paint tested.  All paint is treated as lead-based paint unless proven to be lead-free.  The certified lead hazard investigator or risk assessor evaluates the property looking for potential lead-based paint hazards.  The hazards include damaged paint, paint chips, dust, and situations that might cause paint to deteriorate.  These situations include active water leaks, moisture damage, non-working downspouts and gutters, or windows, doors, and drawers that damage paint when opened or closed.  If the property passes the investigation a lead-safe certificate will be issued for a period of 9 months to 20 years.
