GB/T 14581-1993 is a technical guidance standard for water quality sampling in lakes and reservoirs. Due to the complex characteristics of water bodies in lakes and reservoirs, standardized sampling is extremely important. The standard details the scientific layout of sampling stations for their unique environment, taking into account factors such as water depth, water flow and functional zoning. Clarify the sampling Frequency of different seasons and time periods. Introduce suitable sampling equipment and operation procedures, covering surface and deep water sample collection. Also emphasize the key points of sample preservation and transportation. Provide professional guidance for water quality monitors to ensure that the collected water samples can accurately reflect the water quality of lakes and reservoirs, and support subsequent water quality analysis and evaluation.
