Carancas! A beautiful expanse of land surrounded by mountains, Andes in the distance, livestock and adobe houses every few kilometers and miles and miles of Peruvian wilderness.
This is where part of the EWB spent the past week among the Aymaran people of the altiplano. Even before the Incas, the Aymara people have existed for 2,000 years on the altiplano. Today, the Aymara people live in Peru, Bolivia, Chile and Argentina.
So it was six lucky EWB members and our amazing guide/biologist/teacher/new facebook friend Sylvia from Lima, Peru that were able to spend one amazing showerless week in the Peruvian wilderness.
We arrived last Saturday to the health post of Carancas where we would sleep, test our well water collections and feast on meals of oreos, funcheetzos, cliff bars and wasabi covered peas.
We were excited for our first day in Carancas and luckily arrived on the initiation day of the new Teniente Gobernadors de Carancas. Teniente Gobernadors are the regional presidents of the five sectors of Carancas.
While we were able to introduce ourselves and share a few rounds of Guarana (don´t worry its soda!) with the Tenientes and locals of Carancas…the party had already started well before our two o´clock arrival…so were still not sure if they remember our meeting. We know for sure that a few Carancans remember our visit because we were able to color in our workbook with a few children.
Since the party was bound to continue, we decided to spend our first night in the quaint little border town of Desaguadero complete with chicken feet soup, questionably stained sheets and for some of us lucky ones, an amazing view into Bolivia and Lake Titicaca (not to mention a view of thunderstorms in the mountains and midnight activities that most likely only happen in border towns).
After waking up from what we´re still not sure was a weird dream or reality on Sunday morning, we had a tasty meaty breakfast at the local market (with no other gringos in sight!) and then picked up some supplies for the well testing that was to come. We then headed back to the nice, quiet Carancas and hashed out our gameplan for the well testing that was to come out. During our meeting in front of the heath post in the warm Altiplano sun, a sweet lady named Maria came over chat with us while she took a break from herding her sheep and llamas. It was really interesting to talk to Maria about her experiences in Carancas, and share with her about our project. It seems like she enjoyed our company too, as she offered us some delicious homemade bread, and when she had to leave the area for a bit, she entrusted us ingenieros to watch over her sheep, and even left her whip!
Luckily Dominic and Ally were pretty skilled herders, so she returned very pleased. After finishing our meeting, we performed our first official well assessment on the ¨salud¨ well.
Here’s where we were able to do some engineering in action, or at least chemistry, as we all practiced the proper procedures to test for arsenic and other measures of water quality such as hardness, alkalinity, sulfate, iron, and pH. After getting some practice in, we set up camp within the health post, with the girls finding room in a slightly dusty spare room and the guys making good use of the birthing room. Stephen made some slight modifications to transform/re-imagine the birthing chair as a comfy bed.
The next day represented the first day of well-testing! We were joined by a team from DIRESA and split into two groups, the girls team travelling by pickup truck while the boys got nice and cozy with the DIRESA members travelling by motorcycle. Travelling around the flat, grassy altiplano, the team got perspective about just how spread out the individual households were from one another and the dominant use of the land for agriculture such as potatoes and grazing for alpacas and sheep. Travelling from well-to-well, the team noted that most residents of the region are not permanent, but commute from Desaguadero in order to graze their animals. The majority of permanent residents who continuously use the water are frequently older people who prefer the open country environment from the busy city. Upon testing both deeper tube wells and shallower government-constructed handpump wells, we observed trends demonstrating very high levels of arsenic (up to 500ppb!) but lower levels of other contaminants such as sulfur, while in the shallower wells there were much lower levels of arsenic but significant levels of iron, nitrate, and sulfur due to improper sealing of the wells coupled with instances of poor draining and infiltration of contaminated surface water in close proximity of animal waste and agriculture. Because of this information, the team is now considering whether to focus primarily on the well used by the 30 or so schoolchildren in Central Carancas for our future implementation trip. While we are planning on conducting an alternatives analysis report to explore different methods for arsenic removal as well as treatment options for biological contamination as well as rainwater catchment systems, the school site may be the most effective venue to focus our attention first due to it’s heavy use by children during the school year and support from community members.
In order to obtain our results, we spent the majority of the evenings and the last day and a half conducting the various water quality tests. Some of the tests were quite tedious and extensive, but we were able to pass the time listening to music (including a techno CD Dominic bought in Desaguadero and another CD with the juicy title “80’s American Rock”), as well as sharing stories (with Stephen’s “chicken story” from his time in the Peace Corps taking the cake). Ally and Silvia led the effort to put together some informational posters detailing the educational materials we prepared in Puno and gave out to kids who we came in contact with testing wells and hanging around the Carancas health post. By the time we left the health post, we compiled a binder of the well results, background data on the project, and some educational coloring books for the kids. As we prepared to leave Carancas, we reflected back upon the solid relationship we were able to build with the nurses at the health post, our positive introduction with the tientes gobernadors and local community leadership, and the many samples we were able to take of wells in all 5 regions.
