"While the Harbor Point project's millions in public financing have dominated debate in Baltimore this summer, a carcinogen buried beneath the proposed waterfront development has sparked concerns about the safety of neighboring residents and the people who will work at the site in Fells Point."
"Environmental regulators who oversaw the cleanup of the former chromium plant there 20 years ago have given preliminary approval to build a 22-story tower on the 27-acre peninsula on the Inner Harbor. The soil and groundwater there are riddled with toxic chromium entombed beneath a "cap" of clean soil, plastic, clay and gravel up to 5 feet thick, according to government records.
Workers will have to create a series of temporary openings in the cap to drive more than 1,000 pilings deep into the ground to support the building. They will dig through the clean dirt on top and peel back the plastic liner to expose contaminated soil beneath."
