Rainfall water pH data at IESI la Bisbal (CATALONIA) 97-99

We have classified the pH data we obtained all these months of investigation in the following way :

We have created a database where the days with precipitations are shown with all pupils registered data.

Those values which have been obtained with the pH indicator paper are shown with a decimal figure and those obtained with the pHmeter with two decimal figures (according to the accuracy of the used tool).

Finally, by using an electronic spread sheet, we have made a table where the following values are registered every day: the minimum pH value, the maximum pH value and the pH average of all samples of the day. We have done an evolutive chart of these tree values: minimum, maximum and average.

This last table and its corresponding chart may be viewed by clicking the following icons:

Rainfall water pH data at Schools in SMART Project

In this section we comment the arrived data, via Internet, from the other participating schools, in order to know their situation.

We do not dare to compare their data with ours because:

  • We are not sure whether the data-collection has been done the same way we have.
  • We do not know whether they have take the mesures immediately after raining.
  • They only take data two days a week, whereas we do it every rainy day.

So these data can only be used as a consulting tool, and no conclusions are to be extracted.

Data and charts from the other European schools may be viewed here.

Weather Charts 97-99

The isobaric maps of the rainy days are avalable here. They have been collected from the newspaper La Vanguardia, from October 1997 to March 1998. Anyway, it just rained two days in March (11th and 22th), with an inappreciable amount of rain, so these days have not been added.

This project has been done with other European countries, exchanging data, maps, and other information. English, Dutch and Finnish pupils and other Catalans pupils (Figueres) have also used these maps. They have realised how lucky we are not having to fight against acid rain.

In the conclusion section we are going to explain the effect of the meteorologic situations on the days when the pH values were not as usual.
