Commentary: How Flint Can Help Residents Trust Their Water Again

# data[].attributes.attachment_link.readable_text
Michigan Gov. Rick Snyder recently announced that the water supply for Flint, Mich. is again safe to drink and that he is ending the free bottled water program for the city, an announcement seen by many as signaling the end of the Flint water crisis. Testing now shows that the water system is in compliance with the U.S. Environmental Protection Agency's lead and copper rule, which requires that at least 90% of the taps sampled have lead below the maximum allowable concentration of 15 parts per billion.

The crisis with Flint's water supply system appears to be ending, but the city still faces a more serious and difficult one: a crisis of trust in government agencies and officials. And because of that, now is not the right time to end the free bottled water program.

Since 2014, Flint residents have been endangered, deceived, and disregarded by officials and agencies that are in place to represent and safeguard them. By the middle of 2017, 15 current and former officials were charged with crimes related to the crisis, including involuntary manslaughter. This has created a toxic relationship of distrust between Flint residents and government officials and agencies.

The Flint situation will not be resolved satisfactorily unless public agencies and officials are prepared to go the extra mile to provide residents a universal assurance of safety and to restore the confidence they destroyed with their earlier actions and decisions. At the same time, residents have to be willing to accept a practical, if not optimal, final resolution to the situation.

It now appears that Flint's public water supply is safe to drink, as all of the city's water mains are delivering water that meets and is well below EPA standards. At the same time, not all water entering private property is yet safe to drink; there are still about 12,000 service lines connecting the mains to private property that must be examined and potentially replaced. Even after this is accomplished, some private homes and businesses will still contain pipes that can contaminate incoming water with lead if they are old and extremely corroded, or if water sits in them for hours and is not flushed before use.

The city is not obligated to replace these pipes, as they are privately owned and it is not possible to determine if they were out of compliance before or after the crisis. (Many municipalities other than Flint face the same problem with residents' water safety.) It's also very expensive. Yet if the state and local governments were to replace the internal piping in Flint's private properties with taps testing above EPA standards, it would go a long way toward restoring trust between officials and residents.

In addition, continuing to provide bottled water will give residents a comfortable alternative to the tap during and immediately after their water lines are replaced. This will ease fears of new lead contamination that can occur from flakes of corroded pipe being dislodged during pipe replacement and prior to adequate flushing. Continuing the bottled water program would also provide more time for the most skeptical residents to observe for a while the experience of their neighbors who have gone back to using water from the tap.

The state should also continue to provide health assessments for residents who have resumed using tap water, to help them redevelop confidence that the water is again safe. Once local and state officials agree that the safety crisis has been fully resolved, an independent expert team can be brought in to audit the situation and make recommendations for additional remedial action if necessary.

This process must be accompanied by complete transparency with regard to testing results and guidance for residents in interpreting the data. Residents must be helped to understand why the past conditions will not again materialize and redevelop confidence in the quality of water coming from their taps.

While Flint residents have every reason to be skeptical of their public officials, they will need to exercise some faith in the transition for it to be successfully completed. Residents must be willing, albeit cautiously, to return to normal use of their taps once their lines are replaced, and must be willing to accept a finding of "all clear" after appropriate testing of their homes.

City and state agencies and officials created this water crisis; now they must put politics aside and work together, with a level of zeal that equals the level of neglect that created it, to bring a proper resolution to the situation.

Water is easily available in the UK, and many of us take this for granted. For certain communities in the world, it is not always so readily available, or safe to use. This is the case in the slums of Sub-Saharan Africa, whose inhabitants commonly obtain water from the ground by themselves. Unfortunately, these waters are often unsafe, and contain contaminants. Dr Jan Willem Foppen and his team address this issue, as part of the T-GroUP project, to improve water management in these areas. Their approach combines social intervention with hydrological assessment.
Deprived communities built in unplanned urban areas of Sub-Saharan Africa often depend on groundwater for their daily water needs. Unfortunately, safe quality water is a scarce commodity in these areas. Without political or economic resources to meet these needs, the communities commonly self-supply from the water that runs beneath the ground (groundwater). Much of this water may contain contaminants and pathogens that can lead to disease. The availability of safe water in these locations is a neglected concern for government authorities, even though this need will increase as population rapidly grows, particularly in slums where the majority of the expansion will occur.

The idea is that small successful experiments can spark changes... this process is the essence of transition management

Dr Jan Willem Foppen at the IHE Delft Institute for Water Education, The Netherlands, is facing this issue, in the multi-national project 'T-GroUP - Experimenting with practical transition groundwater management strategies for the urban poor in Sub-Saharan Africa'. To tackle it, the group assesses the availability of groundwater, evaluates its safety, conducts hydrogeological assessments, and organises 'social learning alliances', and 'shared strategic planning' sessions to enable the communities to problem solve together.

T-GroUP - the project and mission
While Dr Foppen is part of a team based at IHE Delft Institute for Water Education in The Netherlands, T-GroUP is made up of an alliance of multiple research organisations across The Netherlands, Sweden, Ghana, Tanzania and Uganda. Together, their aim is to improve the availability of safe water in the unplanned residences of the urban-poor, across Sub-Saharan Africa.

In these settings, which often comprise slums, Dr Foppen describes their water resources as 'patchwork', made up of the occasional hand pump, piped network or borehole. Since there is little consistency, there are differing water tariff structures in place, and it is actually the poorest who pay the most for their water. Little is done to address the issue, as institutions such as councils, assemblies and ministries are rarely consulted about groundwater issues in their regions, and city development plans do not take it into account. This is part of the social challenge that further complicates the situation. As Dr Foppen comments: "There are different types of inequalities and political or social power dynamics when it comes to access to water". He also reports that the groundwater is usually contaminated with various chemicals that seep in from the ground surface, as a result of human activity. An abundance of viruses have been identified, some of which are pathogenic.

There are different types of inequalities and political or social power dynamics when it comes to access to water

An ethos of the project is to avoid telling communities or authorities what to do. Instead, the team learns about the complexities of the regions, and gathers the right people together to discuss the problem. T-GroUP designs small-scale experiments, in the hope that whichever ones are successful in increasing sustainability, these solutions will spread out to other communities, benefiting them too. This approach is named 'transition management theory'. Dr Foppen explains: "The idea is that small successful experiments can spark changes. This process is the essence of transition management".

The T-GroUP team investigates the political and economic situations of each area studied, what the governance arrangements are, and the power dynamics at play. This will allow them to develop a model for improving groundwater sustainability, which they hope could be applied further afield from the sites of study, to other urban areas of Sub-Saharan Africa.

Assessing the situation
As part of the project, the team consider the environmental and hydrogeological perspective, to understand the groundwater flow systems at work. In a previous study, Dr Foppen teamed up with George Lutterodt (Central University College) and Obed Minkah (Hydrological Services Department) based at Accra, to gain an overview of the groundwater flow system at Dodowa, Ghana. Here, they drilled 12 holes, chemically analysed groundwater samples, and considered the geological make-up of the area. The aquifer system was found to contain high nitrate concentrations in the groundwater, due to the infiltration of waste. A similar situation was observed in his study of Arusha, Tanzania, where high nitrate levels were also found in the groundwater. As many households around these sites depend on this groundwater, this is a prevailing health concern.

With little alternative choice, the communities continue to depend on the potentially harmful groundwater

After multiple investigations, Dr Foppen summarises that interventions need to be invested in, in order to reduce waste infiltration of the groundwater. For slums that are located in the lower part of the valley where groundwater discharge occurs, interventions to minimise pollution should be implemented by targeting the source of the issue, upstream, where the contamination of the water takes place. His colleague, Jenny Grönwall (Stockholm International Water Institute, Sweden) conducted interviews in the town of Dodowa, with residents and those within the public water industry. Her study showed that little had improved in the town, which faces an unreliable supply of water from the authorities, leaving people to rely on themselves, and self-supply. With little alternative choice, the communities continue to depend on the potentially harmful groundwater.

Looking to the future
The research team are halfway through the T-GroUP project, and have identified some complex factors that impact the availability of safe water in the slums of Sub-Saharan Africa. By combining hydrogeological investigations with social interventions, they have been laying the groundwork to find possible solutions for sustainable water management in these areas. As a result, the magnitude of the problem is ever more emphasised, as is the importance of raising awareness. Dr Foppen admits that there is no one quick fix, and tackling this challenge will be a lengthy process. Though, it is hoped that through the T-GroUP project, the smallest beneficial change to one community could progressively spread out and benefit others. Time will tell whether this 'transition management' approach will be an effective way of managing groundwater in Sub-Saharan Africa.

What led you from your research focus on the physical sciences to public health issues such as this?
Many problems in the developing world are associated with safety issues. In the developed world, we have more or less overcome those safety issues, although calamities do occur every now and then. One way of keeping safety issues on the agenda of ministries and public entities is to do research about the topic and to publish about it. I have to add here that I am not into public health as such; but examining the safety of groundwater environments and ways to ensure that people can keep on using groundwater. This is not public health. It's a combination of physical and social sciences, really.

How long do you think it could take to start seeing positive changes from this project?
That varies depending on the experiment we're about to carry out. Some are quite successful right from the start, while other experiments seem to be failing completely because we overlooked something. With a bit of tweaking from our side, we can perhaps turn the failures into successes.

We find viruses that have never been found before in any groundwater environment anywhere in the world

Has the main challenge been social, in the communities; or physical, regarding the hydrology?
Institutional I would say. The most important challenge is not the physical side of the project, nor to connect with the local communities, but to get the employees from the various stakeholders to move away from their institutional mandate. Usually, they hide behind the mandate of their institution. We haven't reached that stage yet, but I am sure we'll get there in due course.

How do you think decision-making authorities in the region can be encouraged to provide adequate water resources to the urban-poor slum communities?
Decision-making authorities don't provide water. This is usually done by public drinking water supply companies. Mostly, these are privately run businesses with ministerial representation on their boards or similar body. Decision-making authorities can assist with developing pro-poor policies or legalising households or plots in squatter areas, or by supporting communities to identify solutions for better water provision.

Can your identification of chemicals and viruses in the groundwaters potentially benefit other forms of research?
Yes, absolutely. In a way, the slum areas can be seen as virus playgrounds in groundwater. Nowhere in the world is there as much waste water leakage into groundwater as in slum areas. What we find here is a kind of worst case scenario. Actually, we do find viruses that have never been found before in any groundwater environment anywhere in the world. These findings contribute to the science dealing with the transport of pathogens in groundwater. Some 70% of what we find has not been found before. It is not in any online DNA database. Perhaps this holds unknown virus species. Only the future can tell how valuable that information really is.
