Seeking Info on Toxic Land Concerns Near East River Development. Anyone Know Activist Alan Atkinson?

Does anyone know how to get in touch with this activist, Alan Atkinson, who was protesting against the 800 middle street housing project in Second Ward, near the East River development? We have been considering purchasing a home on a street very nearby the site (literally two streets over near Nagle) and just stumbled across this information detailing the toxicity of the land at 800 middle street. We had no clue that we were considering purchasing near a low-income housing project on toxic land as the home is just a quick walk to the Navigation strip. I wanted to reach out to him to determine if he believes that the surrounding homes should also be avoided as well. Any help or information you may personally have as well would be great!
