HUNTINGTON BEACH
Additional soil samples tested last month confirmed cancer-causing chemicals exist on property south of the Bolsa Chica mesa, but in an area smaller than previously thought, an official for the property owner said.
The “hot” spot is limited to a section where Graham Street dead-ends near the 42-acre Fieldstone property, said Lucy Dunn, executive vice president of Hearthside Homes, which owns the land. The substance involved is polychlorinated biphenyls, Dunn said.
More testing will determine the exact amount and location of the contamination before cleanup begins. Hearthside does not know where the chemicals came from, according to Dunn. They could be related to past oil drilling or illegal dumping, she said.
