What's new in the investigation?

Proposed BASF Investigation

BASF is continuing analytical testing of groundwater, surface water, and sediment in the two areas identified in the previous study. Due to the minimal risks from air particulates, ambient air monitoring is not proposed. BASF is looking into the most appropriate surface cover for DBO with respect to both the contamination and the potential impact on wildlife. Evaluation of chemical transference from un-ionized to ionized ammonia is being completed by BASF in two areas of groundwater interaction with the Detroit River.
