Add to measure the cation and anion to carry on the Piper illustrated manual table method, the method, the degree of hardness valuation of the irrigation water valuation and Simpson method valuation in the plentiful water period. The risk assessment of health, complete the risk assessment of health in Chih-Shan-Yen and Wan-Den. The survey of emergency response, complete returns the Kuei-Jen segment the pollution affairs soil in Ping-Tung City l and groundwater an identification homework, analyzing a result totally have two heavy metals in the soil grounds to have over the situation of the control standard, identify of two people the running water company the underground pump water well all low in control standard. Whole cure completion juniors to go recheck the sample inquisition, investigate a result low in monitor basis value. The gas station inspection work and measures to leak the tube examination, hold the laws explanation of the completion gas station to will there are 114s to attend meeting totally, and complete totally 133 stand two censuses.
