Analysis of Water around NYC-post 2

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.

Analysis of Water around NYC

Being awarded the UGR grant late, I was only able to recently start my project. this study focuses on the analysis of samples of water collected from three different bodies of water around NYC. These sites include Coney Island Creek, the Gowanus Canal, and Newtown Creek. These three sites were specifically chosen because they have been known to be highly polluted sites and therefore I thought it would be interesting to see the types of micro-pollutants and the metal content found at these sites in order to compare them to the results I obtained from the areas in lower Manhattan.

The project is currently underway. I went out to the sites and collected 2 liters of water from each site back on November 12th. Since then the samples have been brought back to the lab and I have filtered the samples. This has been done in order to collect the sediments and other such materials present in the water so that they can be analyzed separately.  This process does however leave the micro-pollutants and metal in the water content which allows them to be analyzed using GC-MS(gas chromatography-mass spectrometry) for the micro-pollutants and AAS(atomic absorption spectroscopy ) for the metal content.
