We published our last study!!

Last week we published the results of our last studies. We printed a thousandth copies and our partners distributed all around the city of Cerro de Pasco and in the capital of Lima. We also organized a virtual event in order to share the results with everybody who is interested. The event included the participation of the mayor of the municipality of Simon Bolivar and two congress representatives and has seen a huge participation of people from Cerro de Pasco itself and from all over the country. In that opportunity not only we presented our last studio but we also took a look at the evolution of pollution and health situation in Cerro de Pasco over the last decade.

The video of the presentation is available on our YouTube channel and directly at this link.

If you want to know more about all details of our investigation some link below will help you, but the short answer is that the studio rise, unfortunately, lots of concerns about the health situation in Cerro de Pasco. We can see an increase of illnesses and pollution over the last few years. Comparisons of concentration of heavy metals in the children of Paragsha have highlighted the fact that, despite the reduction of production of the mine in the last decade, the concentration of such pollutants in their bodies have increased in the last three years. This obviously also dismount the theory that the health effect in the town are the results of pollution of the last decade or so. It is actually pretty clear that the pollution is still active in the town and that the children of Paragsha not only have accumulated it over the years but they are still affected today.

If you want to learn more about the details of the study you can download the summary of the study in English at this link, download the full study in Spanish at this link and you can also watch the presentation on our YouTube channel.


 Meanwhile the Covid19 situation in Peru is slowly improving and we are optimistic that we can travel to Cerro de Pasco soon. Stay tuned for more updates about it!

COVID19 update

COVID19 slowed down our project but it did not stop it.

As we all know the world has changed a lot in the last few months. The travel bans and the global quarantine has obliged us to review our programs in Cerro de Pasco, and in general, a lot of things for our organization.

We were ready to go to Cerro de Pasco in March. We purchased equipment and flight tickets, we had our school ready and students identified. Everything was ready for us to go and implement our citizen science project. Then COVID19 has changed everything. We were forced to first postpone our flights and then cancel them. Schools in Peru were closed and we were unable to properly communicate with our partners.  

Currently the situation in Europe is going better but in Peru it remains critical. In Cerro de Pasco schools are still closed and the forced quarantine is still in place. Travel ban is still in place and there is no official end to it. We were forced to postpone our citizen science project to a later stage.

Our developed word is moving everything online. But Peru, and Cerro de Pasco, is not the same then Europe or the United States. Connections are not reliable and lot of people do not have access to computers and smartphones, moving everything online is simply impossible. Furthermore, not everything can be moved online. We cannot sample water online nor analyze dust and pollution. The majority of organizations are moving everything on the digital platforms, but working in the filed requires a physical presence. The work of Source International requires a physical presence. It can be difficult in some situation, but it is what makes us different from other organizations.  

However, we are moving online everything we can and we are also developing a new manual to be shared with partner organizations, to develop a basic community monitoring system even without us. This manual will be ready by the end of the year and it will be available for everybody who need it. Stay tuned and continue to support us also in this new challenge!

Citizen Science in Cerro de Pasco

Source International will implement a Citizen Science project in Cerro de Pasco with the youth of the town.

Youth are the driving force for change but they often lack knowledge, instruments and a space to share their ideas for the future. We will create all of this in Cerro de Pasco!

Thanks to the partnership with Action Project we will be able to provide equipment and training to 30 students from three different schools in the area of Cerro de Pasco.

We will train ten students and two professors for each school in three different schools. We will also provide equipment to every school. Every student will have access to:

-a multi-parameter probe to measure pH, conductivity and Total Dissolved Solids: three very important parameters of mining pollution.

-several rapid kits to measure heavy metals (lead, arsenic, cadmium, aluminum) concentration in the water: this is the main problem in Cerro de Pasco.

Thanks to the equipment and the training, students will be able to monitor pollution in the water and have a clear understanding of the situation in their basins.


We will also create a Youth Forum in order to give to the students a place to share their results, to create awareness and to advocate for the rights of them and of all the city. The Youth Forum will be hosted in one of the school but it will be accessible for every youth in town. Over time this will be a very important space for shaping the future of the highest city in the world.


In February we will travel to Berlin for the kick-off meeting of the project and in March we will travel to Cerro de Pasco to start the training and to bring the equipment. Keep following us for more updates!
