- the dates where they tried to fix the leaks are around/after the first peak in particle counts (04/23/2010)
- i don't have data for a few days after that because nobody saved the data from the counter i guess and it starts to overwrite it after some while (the white gap).
- the latest peak from last week was due to some technical issues with the HVAC system which they fixed immediately (06/17/2010)
