According to scientists
at the Silent Spring Institute, over 97 million Americans are exposed to
unregulated contaminants in their drinking water, making up nearly a third of
the population. Hispanic and Black
groups are more likely than other racial groups to have these contaminants in
their water, as they are more likely to live in neighborhoods that are close to
pollution sources. These communities are
generally situated closer to wastewater treatment plants, airports, military
training areas, and industrial sites, all of which discharge pollutants into local
groundwater through improper waste management procedures. Some of these pollutants include 1-4 dioxane,
Freon 22, and PFAS, which has been found to be more prolific in drinking water
than originally thought. The news writer
suggests that historical factors such as racism and redlining have led to the
siting of communities of color near heavily polluted sites. The finding supports previous research about
water contamination, with the conclusion that there needs to be more federal
action to regulate these contaminants.
For the most part, the article by Phys.org is a good
summary that agrees with the message of the scholarly article. The title of the news article has an attention-grabbing
fact in its headline, stating that 97 million Americans are exposed to drinking
water contamination, which to their credit agrees with the findings. This contrasts with the title of the scholarly
article, which only states that there are socioeconomic disparities in drinking
water. The scholarly article was more
specific about the pollutants they studied, whereas the news article made it
seem like there were only four important chemicals that the research group
targeted. But according to the
researchers, there are 86,000(!) harmful chemicals in our drinking water (this
could also have been an attention-grabbing headline). An omission the news article made is that urbanicity
(p=0.80) was more highly correlated with wastewater pollution than race (p=.34),
even though minority groups in cities are more likely to be exposed. It’s a significant omission because
environmental justice is mainly an urban issue and not a rural one, so local
governments need to be held more accountable.
Also, the news writer’s message was also more political; nowhere in the
scholarly article does it mention racism or redlining as sources of the problem.
Phys.org
has been my go-to source for science news for a long time. Usually, they pay careful attention to detail
and will offer a deeper explanation of scholarly articles than other popular
science sites. That’s why the omission
about urbanicity comes at a surprise. This
is an important detail because their conclusion is that the federal government
needs to do more to address the problem.
But since it is mostly taking place in cities, urban governments could
be doing more as well. Their conclusion
would have been better if they had criticized urban governments for not doing
more to realize environmental justice.
