INVESTIGATION 3

Asbestos Assessment Report for

Central Brooklyn High School

You have been hired to complete the asbestos assessment for Central Brooklyn High School, and submit your findings in a report. The building materials composing each of the three wings of the school were analyzed by independent petrologists. Wings #1 and #2 were analyzed by teams of geology students from Brooklyn College, including yourself. The results of their work has been compiled (but not averaged, nor verified) by Prof. Powell, who also conducted the analysis of the building materials of Wing #3.

Once INVESTIGATION 2B has been completed by the class, you will be sent the complied petrographic reports for wings 2 and 3 by email.  In addition, a copy of the report concerning Wing #3 can be obtained from the following link...

What Must Your Assessment Report Include? 

1. An analysis and presentation of the petrographic data for Wing #1 and Wing #2.
PLM analyses were conducted on the same set of samples by numerous people, and it is likely that some mistakes will have been made and consequently some analyses will be contradictory. Accordingly, your first task will be to determine what you consider to be reasonably accurate estimates of the composition of building materials in the older two wings of Central Brooklyn High School.

Should all of the data for each given sample simply be averaged together? Should some analyses be eliminated from consideration? If so, why? How do you judge good data and bad data? Certainly you must justify how you arrived at the compositions that you decided to use for the assessment. Remember that you can always return to Investigation 2B in order to re-evaluate questionable data for yourself.

2. A comparison of relative hazardousness of each of the three wings.
Which of the wings presents the greatest health threat to students due to asbestos? Which is the least hazardous? And of course you must justify your conclusions.
3. A suggested schedule of abatement for the school?
Do you feel that all three wings need to undergo asbestos abatement? If not, which ones need abatement and which do not? In what sequence should the wings be dealt with?

Remember, in this instance you are acting as an advising professional and your report will could have personal legal repercussions if you make mistakes. If you recommend that a wing not be abated, but a hazard exists, a concerned parent could attempt to sue you for your mistake. On the other hand, if you recommend that a wing be abated but no hazard existed, then the school board may attempt to sue you to recover the abatement costs. 

4. All petrographic data must be tabulated in an appendix at the end of your report.
