为落实全军八五规划高原卫生学调查的部署，于１９９２年５～７月对阿里地区８０％以上区域的１１３个水源进行了卫生学调查。范围包括部队生活饮用水源、重点要地水源、交通干线水源和藏民生活饮用水源。水源类型为河水、泉水、渗井和湖水，水量较充足。调查发现，所有水源均无卫生防护措施，水源卫生状况，差的占５５．８％；水源水质感官性状良好的占５７．５％，差的占１２．４％；水的硬度ＣａＣＯ３４５０～７２Ｏｍｇ／Ｌ者占１４．２％，个别水砷、氟超标。水源未污者占３１．９％，轻污者占５５．７％，重污者占１２．４％。水源水质综合评价良好的占４２．５％，可用的占２５．７％，差的占３１．８％。
In order to implement the plan for the investigation of plateau hygiene in the Eighth Five-Year Plan of the PLA, health surveys were conducted on 113 water sources in more than 80% of the Ali area from May to July in 1992. The scope includes the army drinking water source, the key water source, the transportation trunk water source, and the Tibetan drinking water source. Water types are river water, spring water, seepage well and lake water with sufficient water. The survey found that all water sources did not have health protection measures and the hygiene status of water sources was poor, accounting for 55.8%; water quality of sensory traits accounted for 57.5% and poor accounted for 12.4%; water hardness CaCO3450 ~ 72Omg / L accounted for 14.2%, individual water arsenic, fluorine exceeded. 31.9% were unspoken, 55.7% were light and 12.4% were heavy polluters. Comprehensive evaluation of water quality of water accounted for 42.5% of good, available accounted for 25.7%, poor accounted for 31.8%.
