In response to the news that several California High Schools were found to have toxic levels of PCBs, ECO-BOND Adhesives, a line of non-toxic, Prop 65 certified adhesives and sealants has developed a special program to provide caulk and adhesives to any school district looking to replace existing caulking in buildings built between 1950 and 1978 when PCB use was banned by the Environmental Protection Agency (EPA).  
  “I have kids in high school, middle school, and elementary school and my wife is a teacher,” said Frank Lange, ECO-BOND Adhesives President. “Making sure that the air quality in the rooms that our kids spend 7 or more hours a day in is safe should be a top priority for all school districts. Window caulking has been identified as a probable source of PCB contamination in schools, so we have developed a program to provide schools with our Heavy Duty caulk/sealant to assist in the replacement of deteriorating or contaminated caulk.”  
  “We will provide product to replace caulk around 200 windows. For school’s needing more than that, we would provide our product at a substantial price reduction.”  
  According to a PCBs in Caulk – QA published by Northern Arizona University’s Institute for Tribal Environmental Professionals no national survey of PCBs in caulk has been conducted so the EPA does not know how prevalent PCB-containing caulk is in schools and other buildings. Based on the small number of test samples gathered from different parts of the country and because of its excellent properties as a plasticizer, EPA believes that the presence of such caulk in schools and other buildings built or renovated in this period (1950-1978) could be widespread.  
  “PCB exposure can have many sources within a school making it difficult to pinpoint the source of the contamination,” said Lange. “However caulk has been identified as a main source of the pollutants which is why we felt it was important to try and be part of fixing the problem.”
