Experiencia del proyecto  Proyecto global sobre muestreo del agua La tutora organizó para ir a las 4 en punto al puente Huayopampa para tomar fotos y recoger las muestras respectivas, el grupo de fotografía llego primero luego el de recolección de muestras junto con la tutora, aproximadamente 15 minutos coordinamos donde y como recolectar las muestras y donde tomar las fotos el grupo de fotografía se dividió, 1 para la toma de recolección de muestras y el otro para tomar el río de diferentes ángulos, la verdad fue difícil recolectar las muestras debido q para bajar era muy empinado y debíamos trabajar en equipo el trabajo de recolección y toma de fotos nos tomo aproximadamente 45 minutos luego el equipo de recolección junto con el de las fotografía y tutora fueron   a la universidad particular de Huanuco para llevar las muestras y ser analizadas  tener los resultados luego de eso cada uno tomo su rumbo a casa esta experiencia nos hizo reflexionar en el uso de nuestros ríos y tratar de que los pobladores cercanos al río cuidaran mas debido a que arrojan desperdicios y contaminan este proyecto no deberían ser solo para los colegios sino con el apoyo de municipalidades o juntas vecinales todos debemos participar en esto ya que el tema se ah tocado pero nadie lo toma a conciencia con esto podemos lograr mucho.

 (Translation from the Introduction) Experience of the Project   Global project on sampling of the water Our tutor organized us to go to the Huayopampa`s bridge to take some photos and gather samples of water, the group of photography arrived first to the meeting point then we compiled our gathers with miss viviana for approximately 15 minutes we coordinate where and how to gathers samples and where to take photos. The photography group divided in two one for samples and other one to take pictures to the river from different angles it was hard to collect samples because we had to get down to the river by a straightened point and we must work together by teams.The collecting work took us 45 approximately then the samples group and photo one must go to huanuco`s university to haut in the samples to be study and to get the results. The experience make us think in the use of ours rivers and try not to waste or throw waster into it, this project won’t be only for school but for the settlers and people who live in the city with the support of city halls or corporate towns We should participate consciously and manage it very much.

International School of Indiana in Indianapolis, Indiana, USA

We are the junior (11th grade) chemistry class at the International School of Indiana in Indianapolis, U.S.A. Cara, Harry, Drew, Brandon and Nick are from the United States and Femi is Canadian. Our teacher, Kerry Hastings, is from the United Kingdom.

This is the first year of our two-year International Baccalaureate (IB) Diploma. One of the assignments within our IB course is the Group 4 Project in which students from all of the different science subjects work together on a common project. This year we decided to make Lamb Lake, Indiana the focus of our Group 4 Project and our chemistry class has chosen to evaluate the quality of the water at Lamb Lake. We thought our IB project would be a great opportunity to be involved in the Global Water Project.

Lamb Lake is in a beautiful, hilly part of Indiana (yes, we do have hills in Indiana!) close to Brown County State Park. The lake is on private property, owned by our biology teacher, and there are only two residences on the lake. The lake was formed by damming a creek and there is a settling pond on the other side of the dam which we will also be able to sample. It is surrounded by forest and is just used for leisure activities such as boating, swimming and fishing. Our biology teacher takes his drinking water from the lake and filters it prior to treating it with ultra violet light to make it potable. His neighbor prefers to filter and chlorinate the water before use. Our hypothesis is that the lake water should be clean and potable, with safe, low levels for each of the tests we will carry out.

International School of Florence, Tuscany, Italy

Dear fellow participants,

The International School of Florence is situated in Italy in Florence, which is a very old and important city as it was the birthplace of the Renaissance and used to be the capital of Italy. Florence is located at 43.78 degrees N. and 11.24 degrees E. The whole of the 10th grade will be participating in the Global Water Sampling Project.

The body of water we have chosen to study is the River Arno, which is the river that runs through our city. This Arno river valley has been settled for thousands of years and has undergone many years of human influence. Therefore we wish to sample the cleanliness of the water. The deep brown colour of the Arno immediately makes someone think that the river is dirty but we believe that we should test the water to give us a clearer idea of how clean the water is and ultimately if it is fit for life. After a series of tests of the water in the river Arno over more than two months, we will be able to come to a conclusion about the cleanliness of the water.

Final Report

Florence – Saturday, June 3rd, 2007

During the course of the third and fourth quarter of the school year, our grade was involved in the “Global Water Sampling Project”. Our aim was to test the quality of the water from the local river, the Arno. The river Arno’s source is on the border between Tuscany and Emilia-Romagna to the North – East at Monte Falterona, and flows 241 Km before reaching the sea. In its course, it crosses several large and small cities, including Pisa and Florence.

To carry on the testing, firstly we found a easily accessible spot along the bank of the Arno, marked by a boulder and so easily found again. Groups of three or more students returned to that spot after school at three o’clock twice a week, so that the time and place would be constant. AT the end of the school day, the team members would take a kit, which contained an oxygen test, a nitrate test and a phosphate test. Included were also a thermometer and a pH tester. This kit allowed us to carry the testing directly on site.

The experiment proceeded for three months, beginning on the 2nd of March and ending on the 18th of May. The test that took place were to measure the oxygen levels, the nitrate levels, the phosphate levels the pH and the temperature of the water. The students who performed the experiment were also asked to write down a description of the water and anything in it.

At the end of the testing period of 14 samplings the following results were obtained. The nitrate concentration of the water in the Arno was 5 ppm which generally low since the maximum limit in drinking water is 50 ppm. The phosphate level of 0.1 ppm is a low reading since the EPA states that phosphate should not exceed 0.1 ppm in flowing water. However water which is uncontaminated by algal blooms would have a reading of 0.01 – 0.03 ppm which suggest that the Arno river might have too much algae. There is a low level of dissolved oxygen in the Arno according to our sampling ranging from 3 ppm to 5 ppm. Since the level of 6 ppm is required for diversified aquatic life, our results would suggest that the river does not support a high level of aquatic life. An amazingly high average pH level of 8.3 is difficult to explain. This may be due to the geological formation thorough which the Arno flows. Since the measurements have been done over a long period of time (March to May) a rapid rise in temperature from 10°C to 24°C has been recorded. This reflects the warm spring and the low level of rainfall.
