By good luck, the weather turned out fine yesterday morn..

We & tree volunteer students did water quality check.

There are always new discoveries in WQC.

Yesterday, even though under the high temperature,

water temperature of wells are lower than I’d guessed.

One well was fastened a lock!

The reason is to protect the well from something will

be thrown into.

Some times, I was struck by the beasty of the result

of the chemical reaction.

The next WQC will be held in the 8th, Nov..

I’ll gladly wait your participation in it.
