Citizen science is a research tool capable of addressing major environmental challenges, including contamination of water resources by agrichemicals, such as nutrients and pesticides. The objectives of this study were (1) to identify the proportion of accurate observations by citizen scientists using rapid assessment water quality tools, and (2) to characterize how a user’s prior experience with water quality tools was associated with the accuracy of citizen scientists. To achieve these objectives, we conducted group testing with over 136 citizen scientists and compared their results from water quality testing of water samples to results obtained using laboratory analytical methods. Following brief training, we observed that accuracy of reported results varies based on the user’s experience level where experienced and expert users shared consistent and reliable measurements. Where erroneous measures were reported, citizen scientists tend to overestimate contaminant concentrations when using colorimetric water quality tools. Additionally, we identified differences in accuracy related to the types of water quality assessment tools used by citizen scientists from each experience group. This study demonstrates the importance of evaluating participant background experience in designing citizen science campaigns.

The National Seminar on Sustainable Water Resource Management in Era of Changing Climate (NSWRM-2014) on 10-11 January 2014 organised by the Institute of Environment and Sustainable Development and Environmental Science and Technology, Banaras Hindu University, witnessed the presence of experts from environmentalists, industrialists and experts on water resources and its management. The deliberations and scientific discussions led to the conclusion that it is not just the resource but the natural capacity to sustain it that requires monitoring, understanding and stewardship. The focus of governance in India needs to move at a faster pace from conventional methods of sector-based water management to more integrated approach for sustainable water resource management. It is more of the people participation that is the future key towards sustainable water resource management in India.
