After filtering the water samples to remove the sediments the samples were placed back in the refrigerator to await analysis. The filter paper with the sediments were collected and each was placed into separate containers. These were placed in 10 mL of a liquid chemical and left sitting in order to dilute the sediments making it possible for analysis of such sediments in the near future. Currently the filtered water has only been looked at to determine the presence of heavy metals and their concentrations in these bodies of water. I still have to inject the samples into GC-MS to determine the types of micro-pollutants that are present in these three bodies of water that are considered to be highly contaminated.
Moving forward I have to return to all three sites to collect more water in order to rerun the tests and analysis that are being run on the first samples. After analyzing the results from the GC-MS part, it would be interesting to see if the micro-pollutants are the same as the ones that were found in the samples from the Hudson River in lower Manhattan last year. Many of these were traces of feces or traces of plastics. Being that these sites are deemed to be highly polluted centers in NYC I would hope and expect to see many types and different types of chemicals after the analysis is performed.
