After remediation of underground contaminants by Jersey Central Power and Light, the city of Cape May, New Jersey intends to purchase numerous properties in order to create a multi-use park. One of the sites is a former manufactured gas plant, which burned coal to produce gas for cooking and heating and left a number of toxins below ground. Those substances range from naphthalene to benzene. The contaminants extend as deep as 40 feet, but plans call for covering the site with clean soil and a geotextile barrier rather than excavating to that depth.
