The first was a government issued request for bids to manage a publicly-owned parking lot in Milwaukee. While not unusual, the bid called for the use of coal tar sealants on the parking lot. Unfortunately governments, schools, big box stores and churches still specify spreading this nasty stuff (a la a 1965 spec) on their on property, but again it happens all the time.
Interestingly, this afternoon an email passed my desk about a new study by the USGS that looked at the concentrations of pollutants coming from urban runoff in....Milwaukee, Wisconsin and nearby Madison.

So the report shows that coal tar sealants are the main source of environmentally-affected contamination, not in some far away city, but in your own town; yet the County still specifies it. Isn't this kind of embarrassing?
