So through a reading last night, we discovered that places who live near the ocean and don't have much surface freshwater or groundwater (like San Diego) actually get their drinking water from a far away source. The water is transported through aqueducts, just like the Romans first built a long time ago!
We then circled back to groundwater, and realized that the groundwater must filter through various earth materials to reach the bottom of a well. It made us think how the ground could actually clean the water on its way down, so we wanted to actually clean some of the dirty water we had stored from September. This water we couldn't get clean from the tools we used then (i.e. strainer, coffee filter, strainer, colander). But we wanted to see if sending the dirty water through the various earth materials (because the space between their pieces may be smaller than a coffee filter's holes). would make a difference. And it sure did! Look at our results from above!!! WHOAH!
More of our questions are being answered...
What new things does this make us wonder!
