The New Jersey Department of Health recently published guidance for the evaluation and management of a certain type of flooring that may contain mercury. The New Jersey Department of Health guidance document may be found on the NJDOH website:

Concerns regarding these flooring types have been the subject of news reports that have highlighted school districts in New Jersey and across the nation. The flooring types in question include rubber-like and water-resistant materials that are typically poured polyurethane that utilizes phenyl mercuric acetate (PMA) catalysts. These materials were historically installed in school multipurpose rooms, auditoriums, cafeterias and gymnasiums between the 1960s and the early 2000s. Testing has revealed that materials containing PMAs can break down over time and release odorless, colorless mercury vapor.

SDA Flooring Initiative
The SDA, in consultation with the New Jersey Department of Health and in accordance with their guidance document, is advancing an initiative to further evaluate those installed materials in SDA delivered school facilities. SDA plans to conduct site visits and bulk sample testing of those identified flooring types along with indoor air screening in the location of the installed flooring where needed.
