Group Members: Diana Samaroo, Ralph Alcendor, Urmi Ghosh-Dastidar, Muhammad Ali Ummy
Title of Activity: Chemical and Biological Analysis of Water Quality
Location/outside partner: Beach-front at Brooklyn Bridge
Timeline for the session: 9:30 am - 2:00 pm
Agenda:
9:30 - 10:30: Living lab fellows, working in groups of three to five (including Robin Michals, Karen Goodlad, Crystal and Dimitri) will meet at the "Beach front" at Brooklyn Bridge (click here for map/directions) to collect several water samples (stagnant and flowing).
10:30 - 11:45: Living lab fellows and participants will return to NYCCT, Pearl 304 laboratory to perform several water analysis tests (working in groups). (Instructions will be posted on the use of equipment)
Experimental samples: stagnant and flowing water collected at Beach-front
Control samples: City Tech fountain water and/or Distilled water
Using test strips from kits, a series of qualitative and quantitative measurements will be conducted on ALL water samples. The test strips will assay the following: pH, iron (chemical symbol Fe) level, hardness of water, nitrite and nitrate levels.
In addition to these chemical analysis, fellows and participants will determine the microbial activity/growth in ALL water samples. (NOTE: Since microbial activity requires a few days to assay, this section of the experiment will be done ahead of time). Hence, presence of microbial growth and the number of microbial colonies will be determined and counted using growth media and a microscope.
11:45 - 12:45 pm: (early) Working Lunch
Fellows will work on gathering/organizing of data and results to report to entire seminar group. This will include the mean (average), median, standard deviation of all pH , hardness, iron, microbial activities, nitrate and nitrite levels of the various water samples (total of four samples).
12:45 - 2:00 pm Groups Presentation of Findings
For each group presentation, include the following: hypothesis, a combination of charts and/or graphs (this can be done using excel spreadsheet) and/or text (data results), image, conclusion. In addition, discuss the importance of water quality in terms of pH, microbial population, hardness, iron levels, nitrite and nitrate levels and its impact on the environment and/or society.
Post-Seminar: Groups will post on OpenLab any charts/graphs/photographs obtained from the "Chemical and Biological Analysis of Water Quality" experiment and provide comments on the seminar.
