New Jersey has over 18,000 known contaminated sites under remediation and tens of thousands of additional sites that have been cleaned up to some degree but still need to be watched. Some of our state’s 3,600 public and private school buildings sit on or near these sites where problem pollutants were dumped, spilled, leaked, or intentionally used. Pollutants may include:
The number of schools on or near contaminated sites is not known. The New Jersey Department of Environmental Protection (DEP) does not maintain a separate inventory of such K-12 schools. The DEP maintains a Known Contaminated Sites (KCS) list on its website, but additional unknown contaminated sites are certain to exist. DEP can provide any known information about specific school sites upon request.
If a school is on or near a toxic site, it does not necessarily mean that staff and students are endangered. What it does mean is that the local association should investigate the situation to see if it necessitates remediation. The purpose of remediation is to prevent human exposure to contaminants in soil and groundwater that can occur on playgrounds and playing fields. Exposures may also occur through the ingestion of well water or when chemicals or their volatile vapors travel through the soil and enter the school through the foundation, crawl space, or slab.
In the past year, three local associations worked through their UniServ field representatives to obtain technical assistance on site cleanup from New Jersey Work Environment Council (WEC) industrial hygienist Adrienne Markowitz.
A vapor removal system was put in place at Atlantic Highlands Elementary School to stop the intrusion of vapors from benzene, toluene, the gasoline additive MTBE, and other gasoline ingredients. The Atlantic High- lands Education Association asked for monitoring to ensure the remediation was effective. Leaking under- ground fuel storage tanks were removed from all 19 public schools in Cherry Hill beginning in the 1990s. Concerns about possible remaining pollutants surfaced due to illnesses among school staff and lack of post-removal testing and closure reports. The Cherry Hill Education Association and the Educational Assistants of Cherry Hill insisted that the district produce documentation regarding the remediation of the sites.
Soil contaminated with historic fill containing VOCs, fly ash, PAHs, and lead was removed from the new playground of the Martin Luther King, Jr. Middle School’s Lester Rutland Resource Center in Paterson during the summer of 2010. A multilayered barrier was installed and a restriction was placed on the deed. The Paterson Education Association monitored and observed the process.
Local associations, staff, and parents should insist on the best remedies for contaminated sites, advocating for actions listed here. These methods can be costly, so beware of recommendations for less effective measures, even if they come from the DEP.
DEP site remediation changes that went into effect in May 2009 created Licensed Site Remediation Professionals (LSRP) to perform site investigations and conduct remedial actions. The DEP issues a Response Action Outcome (RAO), which is the LSRP’s writ- ten professional opinion that a location was remediated in accordance with applicable statutes, regulations, and guidance. The DEP also audits some cases and reviews all cases with potential impacts on humans and environmentally sensitive natural resources and where contaminants may migrate off the site. The DEP has the final say on remedy selection. Sometimes polluters are found and made to pay for remediation.
