鉴别水质在地下水和地面水源比较充足的情况下,还要注意选择清洁的水,洁净的水,无味的水。水受不同物质污染,就会产生不同的味道。如含有机物的水味甜,含高价铁的水味涩,含硫酸镁或硫酸钠的水味苦,含氯化钠的水咸味,含硫化氢的水有臭鸡蛋味。这些颜色、味道异常的水都不能饮用。到岩石裂隙处找水在各种不同时代和不同岩石成分的岩石裂隙中,不同程度地会有地下水,而岩石裂隙是否透水和含水,取决于各种岩石是否有裂隙或空洞,包括溶洞和气孔。一般来说,各种沉积岩、火山岩和变质岩都有裂隙存在,在这些岩石的裂隙地带,一般都可找到水源。
Identification of water quality In the groundwater and ground water more adequate circumstances, but also pay attention to choose clean water, clean water, tasteless water. Water contaminated by different substances, it will produce different flavors. Such as organic water-sweet taste, with high-priced iron water, astringent, magnesium sulfate or sodium sulfate water bitter taste, salty taste with sodium chloride, hydrogen sulfide-containing water smell of rotten eggs. These colors, unusual taste of water can not drink. To find water in rock fissures In rock fissures of different ages and different rock compositions, groundwater will be available to varying extents. Whether rock fissures are permeable or water-wet depends on whether there are fissures or voids in various rocks, including caves and pores . In general, all kinds of sedimentary rocks, volcanic rocks and metamorphic rocks have fissures, and in the fissures of these rocks, water sources are generally found.
