RE bugs in water

Question

I've pasted a link to the official NYC water website and specifically to a PDF file containing extremely detailed information on what's in our water. I only looked over it quickly, but i think one can infer that no insects were found in our water. Take a look and see for yourself - they list EVERYTHING that was and was not found. Besides, has anyone really ever found an insect coming out of the tap? http://www.ci.nyc.ny.us/html/dep/pdf/wsstat03c.pdf
