This visualisation speaks about the ways in which toxics can be present yet invisble, the uncertainties around them and the local understandings and fears related to this not-knowing, or knowing after the fact, and the material traces and infrastructures of industrial projects through which toxics continue to spread and may be made visible.
I think this is a powerful image where the aesthetics and argument come together seamlessly, so I don't have any suggestions on how to enrich it.
The image is a picture, but the source is not listed -presumably it is the author of the piece. The composition places the storm water drain right at the centre, drawing attention to it. As a black hole in an otherwise familiar-looking landscape it evokes the uncertainties and threats of the toxic flows that may be seeping into the river at this site.
The captionis evocative and explains the issue in a concise way. It gives the reader a sense of the residents of Flint and their experiences of living in this particular place and environment. A breif description of the presumed health effects of PFAS would clarify what is at stake with this recent discovery.
This picture visualises the opposition, but also the close proximity and inseperabability of the 'natural' river environment and channels of toxic industrial waste. It brings to the centre a storm water drain that may be easily overlooked otherwise.
