Federal environmental officials are conducting tests to determine whether harmful contaminants from an old industrial complex in Lansing are seeping out of the ground.
The U.S. Environmental Protection Agency says the testing is for vapor intrusion at six homes surrounding the former Adams Plating Co.
TheLansing State Journalreports the site is one of an estimated 4,000 in Michigan that the state Department of Environmental Quality says has the potential to leak dangerous vapors that have long lain dormant in soil and ground water.
The DEQ says the sites have histories as dry cleaning facilities, old gas stations that may have had underground storage containers or former manufacturing facilities. Vapors can enter a structure through cracks in cement, utility lines or pumps.
