Gov. Chris Christie has announced that the State of New Jersey will move ahead and require schools to test their drinking water for lead.

Go to the Lead in Drinking Water - Schools and Child Care Facilities webpage to see the Governor's news conference video .

Lead in school drinking water has become a major issue since its detection in Newark schools.  Here is the USEPA Revised Technical Guidance, 3Ts for Reducing Lead in Drinking Water in Schools that are served by public water systems.  The 3Ts are Training, Testing & Telling.  This applies to those schools which get their water from outside water sources.  If a school has its own water system then the Lead & Copper Rule applies.  The USEPA published this document in 2006.

Click here to go to our Lead in Drinking Water - Schools and Child Care Facilities webpage.  This webpage has important links to Guidance Documents, including the Updated Lead in School Drinking Water Online Webinar.  This includes information from the USEPA, the NJDEP and Garden State Labs. Both the New Jersey Legislature and the United States Congress have proposed bills requiring schools to do lead testing in drinking water.  The proposed bills are posted on this webpage.

Here is the Updated Lead in School Drinking Water Webinar, held April 19, 2016.
