Toxicity Problems on Properties

How does one go about researching toxicity issues on properties in Brooklyn? I am considering property in Williamsburg and have checked out PropertyShark.com and have discovered that adjoining properties have toxic issues. The property I am considering buying does not, but is surrounded on 2 sides by issues.

PropertyShark does not explain what the toxic issues are. I can get the block and lot numbers of the affected lots. With that info, is there a website or agency that would give me specifics as to the toxicity? Is this something I should be concerned with in purchasing a house near these sites? Thanks.
