Students enable widespread water monitoring in India

Students enable widespread water monitoring in India Lisa Lock Scientific Editor Andrew Zinin Chief Editor When a local community gets involved in environmental monitoring, its efforts can build awareness of local environmental issues and provide more abundant data than scientists can collect on their own. But how does the quality of the data compare with readings taken by professionals? The state of Bihar, India, was the perfect place to find out. More than 90% of the population relies on groundwater for cooking and cleaning, but at times, that same groundwater has been reported to be contaminated with arsenic, iron, manganese, nitrate and uranium, all of which can cause health problems. Laura Richards and colleagues compared community members' groundwater-monitoring results with those of professional scientists. The researchers recruited community members affiliated with one secondary school, three colleges and one professional institution. Many participants were teenage students, but some were adult employees of the schools. All told, the team included 583 people. The participants collected water samples from places where people access water during their daily lives, such as hand pumps that supply drinking water. The research team brought the samples back to the University of Manchester on commercial flights, then analyzed them at the Manchester Analytical Geochemistry Unit laboratories. The results, now published in the journal Community Science, were broadly similar to those collected by professional scientists, showing that participatory science is an excellent way to increase the amount of data environmental scientists have to work with, the authors say. With more data, scientists can spot spatial patterns that might be overlooked with a smaller workforce. Participatory science can also generate interest in research, potentially bringing more women and minorities into the field. More information Laura A.
