Water: A Tale of Trickled Down Inequities
- Current perpetuation of past water use practices continues and further exacerbates likely future inequities in water access. Learn what ideas can be implemented to mitigate these effects.
From the fields at Standing Rock Native American Reservation, the chant “Mní wičhóni” could be heard reverberating through the gathered crowd of protestors. This Lakota phrase, meaning “Water is life,” was taken up as a unifying message grounding the demonstrators’ mission. In 2016, non-Native environmentalists from around the world stood with the indigenous leaders to fight back against the construction of the Dakota Access Pipeline (Figure 1), which would have threatened several sacred sites and resources like Water itself. But issues of water access, rights and sustainability extend far beyond the Reservation.
Inequitable water practices of today are relics of bygone conventions
As water extraction became significantly easier in the 1950s boosted by an increased rate of withdrawals, water consumption behavior drastically increased in industry and the household; easier water extraction prompted a consumption increase of around 45% since this abrupt shift in economic management. But as past water systems are both failing and persistent in the present day (e.g. crumbling infrastructure alongside “white flight” and comorbid disinvestment; Walton, 2016), disparities remain in who can freely utilize this vital resource.
A community’s relationship with water tracks several factors such as geography, income level, and gender – overall, marginalized communities are more likely to be exposed to unhealthy water conditions. Their drinking water tends to be unsafe compared to their non-minoritized counterparts (i.e. probability that their community water systems incurs serious health violations). Indeed, race is a strong predictor of access to clean water. At the other extreme, excess water also poses a problem. As green spaces (e.g. forests, parks) that act as a sponge for rain are less common in the paved “heat island” of many communities of color, precipitation accumulates into urban floods before it is lost as runoff. And since weather patterns are projected to shift as a result of climate change, such water destruction will only become more common and put already vulnerable populations at greater risk.
Inequities are seen at various scales; industrial water distribution practices are often viewed as unbalanced, favoring powerful entities. For example, California’s complex water allocation system allows wealthy farming corporations to “insulate themselves” from the constraints (e.g. limited access to surface water allotments) binding the less powerful. Users with seniority (those whose water needs are given priority by grandfathered-in agreements) are disincentivized to cut back their usage; their status ensures they are due their allotment, in a state-based manner that may or may not depend on the overall level of the water source being drawn from. More junior users are thus vulnerable to being left high and dry. This is then more likely to affect minoritized people who are less likely to have this seniority, further hindering their ability to fully and equitably conduct business or have a healthy community. More research is needed to better understand this link though.
The inequities continue in the public health arena. There has recently been a rise in public scrutiny about PFA substances (PFAS), a particularly potent group of compounds that are ubiquitously found in a wide variety of common items (non-stick cookware, clothing, etc.) and are associated with a host of adverse health effects. They are colloquially known as “forever chemicals”, so-named for their long-lasting staying potential in the body once introduced. While toxic levels have been found in workers at factories that directly work with PFAS, they also leak into neighboring communities through public water supplies and other modes of exposure. In one instance, a young American child had more than 100 times the national average PFAS in their bloodstream (warning: explicit content), putting them at exceedingly high risk of their development being seriously compromised. Minoritized populations are more likely to shoulder the burden of downstream PFAS effects. For example, fresh food is less accessible in communities of color, meaning they are more likely to be exposed to these chemicals through processed food containers. As socioeconomic status is associated with race, comparing these distributions simultaneously illustrates that these factors interact (Figure 2). In fact, a recent study found that communities of low income were 15% more likely and those of color were 22% more likely to be near PFAS sites (“sacrifice zones”) than would be expected if the factors were not related.
These differences by identity can be seen the world over. In communities where water infrastructure is lacking, accessing water often requires intensive individual-scale labor. People in these disadvantaged communities travel to and transport water back from a freshwater source, carrying on average 42 pounds of water 3.5 miles every day. Since these infrastructure-underdeveloped societies tend to have a deeply gendered division of household labor, this burden primarily falls on young girls; 129 million school-age girls worldwide are contained in the home, citing the need for someone to perform menial tasks like fetching water. This has a wide range of consequences, from sustainable population sizes to economic growth.
Future projections warn of widening gaps
The global water supply is buckling under the strain of current extraction practices (Figure 3). A 2019 study found that between “15 and 21 percent of water [sources] that experience groundwater extraction have slipped past a critical ecological threshold [of sustainability] …. and by 2050, that number could skyrocket to somewhere between 40 and 79 percent” (Borunda, 2019). This increase is projected to be due to a combination of factors. With evermore stressed sources, this depletion will put evermore pressure on living systems.
Though we often think we can “technologize” our way out of natural systems’ constraints, their effects trickle down to the human realm; the Water Wars are conflicts stemming from the scarcity of clean water. It is projected that more than half of the global population are expected to live in water-stressed areas by 2025, while more than half of the global urban population will face water scarcity by 2050. These pressures are already being felt around the world, with violent repercussions. Reminiscent of the 18th century economist Thomas Malthus’s ominous prediction, as water supplies fail, so will the heavily water reliant food infrastructure. And with an empty stomach, social bonds are more likely to fray, putting the very fabric of social cohesion at risk.
The water infrastructure in the United States is in desperate need of an upgrade, as was vividly shown in the Flint, Michigan crisis of 2014 that drove the thousands of residents to emergently use an alternate water source than the public reserve. After such disasters, there is a heightened and urgent need for clean water, often exposing long-standing vulnerabilities in water access. This usually requires an increase in disposable water bottle usage, contributing to the plastic problem that ultimately hurts many of the communities it was proximately trying to help. Crises of this sort and magnitude are expected to become more common as a result of climate change, exacerbating the long-standing neglect of the water infrastructure; thus, more sustainable preventative measures urgently need to be put in place.
Water is an essential part of life – without it, life cannot be sustained. People can live on average without food for roughly three weeks, but only about three days without water (Puia, 2020). As such a critical component of biological systems amid exponential population growth, maintaining the very limited water supply is more than just a heady value – it is synonymous with our survival. As the Standing Rock showdown strikingly illustrated, current systems inequitably distribute water rights; it is thus essential that we both use it efficiently in the present and advocate for its equitable and sustainable use in the future.
Our window of opportunity is quickly closing. Here are some potential, multi-tiered ways forward:
- As stated above, water has not been treated as a precious resource. It is the government’s responsibility to create a viable long-term solution to the crisis. One strategy that Kelsey Leonard advocates for is that Water should be treated as a person, with all the rights that come with it.
- Economists and environmentalists alike say that water is severely undervalued in modern times. Though efforts to socialize the costs of water use have merit for uncoupling access with income, this also disincentivizes conservation, as a consumer cannot see their own usage levels; pricing should reflect both factors to support both goals simultaneously.
- The system of water distribution should be re-worked with water scarcity in mind; California’s landmark Sustainable Groundwater Management Act of 2014 aimed to do just this. Other states should follow California’s example by adopting the correlational approach to distribution that allots water proportionally, rather than absolutely, relative to the volume of the source. Seniority should be granted to indigenous communities (as they were initial stewards of the land).
- As there are low- and high-flush toilets, the water processing infrastructure should be rethought to include two water pathways. Greywater (relatively clean water, e.g. from washing vegetables) should be diverted for recycling purposes to a city-wide repository that can be treated relatively lightly relative to dirty water sent to the sewer system. As climate change will make it more likely that precipitation falls as rain than as snow, water capturing systems will be increasingly important to build; doing so must be sanitary. Stormwater drains are potential pollution points to freshwater. Better filtering and compartmentalizing should be used to minimize contamination and capture runoff from being lost to the ocean.
- As parts of the country have excess water while others have a marked scarcity, it might be worth considering relying more heavily on an interstate distribution system (i.e. pipelines, tunnels, aqueducts) connecting these areas. This must be done equitably and with a diverse representation in the executive committee to keep community and environmental needs at the forefront. This is not a silver bullet though, as it would be an incredibly challenging logistical venture.
- Innovative urban planners have creatively designed their cities to adapt to seasonal flooding. As a group in Santa Barbara attempted, covering a body of fresh water to slow its evaporation is an intriguing option, though its particulars still need to be fine-tuned. Proactive measures need to be taken not just in already sheltered wealthy areas, but those low income communities that are more likely to feel the effects (Pottinger, 2019).
- Studies have found that around 70% of the world's freshwater supplies withdrawn annually go toward agricultural farming. While water is undoubtedly necessary for maintaining crops, livestock, etc., this massive usage is “notoriously inefficient”. This may be tightened through initiatives (i.e. water sharing across farms by establishing a “water market”) and pivoting to growing more water-wise crops, etc.
- Improve promising technologies. Desalination is a method for turning salt water into potable water. It has yet had limited success though, as it costs more to process and extrude the saltwater than there is financial benefit. By the principle of parsimony, apply these technologies at the source so they don’t create exponential instances of harm downstream.
- Pivot marketing and manufacturing strategies toward more socially and environmentally sustainable practices. Water privatization must keep these factors in mind. It is notable though that the beverage industry is better managing its water usage compared to the agricultural and meat industries. Rather than targeting vulnerable populations, companies should reduce the amount of plastic packaging of their products and refrain from predatory practices. After all, adopting this alternative growth mindset is in their interest in the long-run.
- Though total water use is trending downwards in the present day, Americans’ usage is far higher per capita than other countries’. Efficiency can be increased in several ways. Leaks are a primary mode of household water waste – addressing these is good for the water table and the water bill. Plant waterwise plants.
- If you have water lying about that you are not going to use, consider pouring it on the plants outside, rather than down the drain. Reuse uncontaminated water for multiple purposes. Though household wastewater is trafficked toward the main sewer line, you can retrofit your house to more directly recycle and repurpose lightly used greywater that has neutral (even beneficial!) impacts on other household water-using systems.
