| A previous study of Lake Macatawa showed levels of lead and polycyclic aromatic hydrocarbons (PAHs) concentrations over EPA probable effect limits in one location. This may be due to a leaking underground gasoline storage tank near this site. This study focused on sediment analysis of more than 30 areas adjacent to this site to help determine the extent of sediment contamination of lead and PAHs. A solid-liquid extraction procedure for PAHs was employed and a gas chromatograph-mass spectrometer was used to identify and quantify PAHs extracted from sediment samples. Microwave-assisted acid digestions and inductively coupled plasma spectrometry was used to determine lead concentrations in the sediment samples. A Geographic Information System was used to plot the quantitative results of the analyses versus geographic location for each of the ~30 sites. Results will be interpreted to identify possible sources of this contamination. |
