Citizens science is a fast-expanding field of science in which the public becomes a scientist. Citizen science is a big one, with citizen monitoring and testing water quality being one of the many areas where they have helped. Quality of water is also an important part of the environment, not only for aquatic life, but also for people and their health.
The Use of Citizen Science in Monitoring and Testing Historical Water Quality
We have had citizen science used to observe and test past water quality in several forms. Most popular of these is taking water samples from volunteers living in the watershed. These samples are then analyzed in a laboratory for chemical and physical parameters such as pH, dissolved oxygen and nutrients. The outcome of those tests is then used to build a chronology of water quality in a region. The data obtained in this way can offer important information about long-term trends and patterns of water quality, that can be useful for scientists and policymakers when it comes to deciding how to protect and sustain the world’s water resources.
A different form of citizen science in monitoring water quality includes monitoring equipment – water testing kits and sensors. These instruments enable the citizen to monitor water quality conditions in real-time and they also give data to scientists to use in their studies. Data-collecting and data management is done in mobile apps and websites for citizen science projects, so it is easier for citizens to participate and for scientists to have the data they want. This type of data-gathering has the benefit of being almost real-time – this can be particularly useful for spotting changes in water quality and identifying a threat early.
Advantages and Challenges of Citizen Science in Water Quality Monitoring and Testing
Water quality monitoring and testing can be made better by citizen science for several reasons. The most notable upside is more data points obtained. Citizens can sample water, measure water quality and do so much more than a tiny team of scientists could do alone, if they get engaged in sampling water and keeping track of the water quality. This enables the water quality to be more easily visualized for any given place, as well as reveal patterns and trends that otherwise wouldn’t be noticed. This additional data can also be applied to pinpoint areas in which water quality can be improved, so conservation and management measures are geared toward them.
The other benefit of citizen science for water quality monitoring is the fact that more people are becoming informed and engaged with water quality problems. By involving citizens in water quality data collection and reporting, citizens will be more informed about the conditions of their local waterways and they will be more likely to act to maintain them. This kind of public engagement can also help raise funds and momentum for water quality research and management programs as people will speak up more vociferously when they are in the process themselves.
There are other barriers to citizen science in water quality monitoring and testing. The most difficult aspect of this is the quality and reliability of citizens’ data. To mitigate this, most citizen science projects offer training and support for volunteers so that they can collect the right data and at the right times. Some projects might also ask volunteers to pass background screenings or certifications, which can make the project expensive and complicated.
Another is that the citizen data they gather is representative of a given area of water quality. That’s what we need to do in an organized and planned way so that we can take water samples at a representative sampling of sites and at the right time of year. This can be particularly hard when we live near big lakes or where water quality varies widely.
Impact of Citizen Science on the Accuracy and Reliability of Historical Water Quality Data
It has helped with the quality and timeliness of old water quality records based on citizen science. If lots of people are involved in data gathering and data analysis, we can find trends and patterns which otherwise wouldn’t show up. Through surveillance devices and apps, citizens now have more control over what data they collect, which can then be analysed in science.
Data from citizen science isn’t always as reliable as data from professional scientists, of course. Because the citizens may not be training or being trained in the same way as a professional scientist, and they might not be employing the same methods or equipment. Therefore, data that citizens produce should first be screened and verified before it is employed in scientific investigations. As a solution to this, many citizen science endeavours mandate that volunteers undergo training and certification, and strictly adhere to procedures for data collection and interpretation.
Improving Public Engagement and Education About Water Pollution Issues
Participation by citizens in monitoring and testing of water quality has facilitated public participation and information dissemination on water pollution. When citizens have a say in how data is collected and interpreted, they understand more about the state of their own waterways and are likely to do something to prevent them. And more active publics can help generate more funding and support for water quality research and management initiatives, since people will speak up for the programs more strongly when they themselves are actively engaged.
Citizen science can also be used to give people access to data and information about water quality. All of these projects make the data collected by volunteers available to citizens on mobile devices and websites so that they can access water quality data. Having this better data at hand can educate people on water pollution and spur them to intervene to keep their local waterways clean.
The Influence of Citizen Science on Policies and Regulations Related to Water Pollution
Citizen science for water quality monitoring and analysis has made huge differences in water pollution policy and regulation. Citizen science initiatives have been able to point out where water quality could be improved, and where contamination is coming from, through the help of a large and robust dataset. Such data have provided guidance on water-pollution prevention and water health policies and regulations that support the well-being of aquatic life and humans.
Some of the citizen science data has also been used to push back against prevailing policies and laws, and demand stricter protections for water quality. This has increased public interest and engagement in water pollution and resulted in better policies and regulations being developed.
Integrating Citizen Science with Traditional Water Quality Monitoring and Testing Methods
The citizen science projects were mingled in various ways with traditional water quality monitoring and testing. Most widespread of all, is by adding citizen science data to monitoring initiatives already in place. An agency might have professional scientists sample water and collect water quality data, and collaborate with citizen science projects to get other data from citizens. This can give you a better picture of water quality over a geographic region and highlight trends and patterns that would otherwise be hard to detect.
The third type of integration is citizen science data that is combined with data from other sources (eg remote sensing and modelling). This can be used to build up a more comprehensive picture of water quality over time in a particular region.
The Future Outlook for Citizen Science in Historical Water Quality Monitoring and Testing
The future for citizen science as applied to historical water quality monitoring and analysis looks bright and promise-laden. In the coming years, with technology ever more accessible, more and more citizens will become involved in water quality monitoring and testing and offer ever more accurate and detailed information.
These pressures to hold water quality management transparent and accountable are only going to fuel the growth of citizen science in this area. The more citizens realise the value of water quality and the consequences of pollution, the more they will demand that information is available to them, and that they become involved in water quality monitoring and testing.
But there are also difficulties ahead. Perhaps the most difficult aspect is the validity of citizens’ data collection. This includes constant training and support of volunteers, and the adoption of new technologies and ways of capturing and analyzing data.
The other problem is that the citizen data will be indicative of water quality in a particular place. This needs planning and coordination so that water samples are taken at representative sites and at appropriate times of year. This is particularly hard in places with vast water masses or where water quality can be quite dissimilar from one place to another.
Citizen science for the analysis and monitoring of historical water quality is a burgeoning area with a very bright future. When we get citizens engaged in capturing and interpreting water quality data, we have the opportunity to make a more accurate and complete record of water quality and educate people about the water pollution problems. As long as we keep funding and supporting this, the future of citizen science in this space is endless.
