Click on the area of Rico you'd like to see the Lead Concentrations test results for. There is approximately one page for each block in order to make all the data readable. Note that when your mouse pointer is over a part of town for which there IS map data, your cursor will turn into a hand to indicate the hyperlink to the map page - just click to view the map. If there's no data, the mouse cursor will remain an arrow. Return to this page to navigate to another section of town.
