We arrived in Pingyao, Shanxi, on the morning of July 25 and then met up with three students from Taiyuan University of Technology. After lunch, we took the bus to the Liangjiabao village and immediately started testing the water. We took samples and did arsenic and turbidity tests for all filters, plus iron, alkalinity and nitrate photometer tests for a selection of the filters. Thanks again to Palintest for all the equipment!
我们7月25日早晨到达山西平遥和太原理工大学的三名同学集合。吃过中饭后坐车前往梁家堡，立即开始测水。我们对所有的慢滤池采了水样，测了砷含量和浊度。对一部分测了铁，碱度和氮含量。再次感谢Palintest的所有仪器！
While we were testing the water, we found some families had increased the flow rate on two new filters fitted with taps. Since this is likely to affect arsenic removal, we adjusted the flow rate and advised them why it was important not to change this.
在测水的过程中我们发现有些家庭对于有开关的滤池增加了流速。因为这样会影响除砷效果，我们重新调整了流速并向他们解释了为什么不应该改变流速。
Kate discussed the August trip with Liang Honggang’s father. The main focus was sourcing the materials, deciding a price for each filter and arranging accommodation for Tsinghua, Taiyuan and Michigan University students participating in the trip.
Kate和当地的人讨论了搭建材料，确定价格，安排住宿等问题，为8月份清华，太原和密歇根大学的行程做准备。
It was already 4pm on the 26th when we finished all the work in the village. On our return to Pingyao, we visited hardware stores to arrange materials for the August trip and training. It is a very rewarding trip.
结束所有工作已经是26日下午四点了。在回去之前我们还到五金店预定了材料。这次行程非常充实！
