Alhué´s Fieldtrip

My Favourite Fieldtrip was the last one. We come to Alhué, 3 hours from Santiago to the southwest. Is a little town called Villa Alhué that has serious problems of pollution, caused by a mining that waste dumps in the river. We went there to investigate the effects of the mining on the environment. Sadly the effects are easily to see, the biodiversity decrease, the beekeeping it is over, and the water in the river is orange in some places.
The fieldtrip was amazing because we entered in private’s properties and we had to stay very quiet if anybody looked the surroundings we had to run very fast to any hideout. But was incredible to discover the orange hidden waste, really really hidden, we had to crossing the river and walk kilometres to find it. And was not the only, others guys find another few kilometres further. Then the teacher brought some appliances to measured electric conductivity, pH, dissolved solids, and with a shovel the guys took samples of sediments in the river. Now we have to analyze the samples in laboratory to show the effects of the mining in this part of the river. The next Field Trip will go to the higher part of the river, further than the withdrawal mining, there, we think, the conditions are the best, without the mining pollution.
