1st, subject content and applicable scope
This standing operating procedure has drunk with the naturalmineral water water source and the product specification, theexamination and the symbol, the packing, the transportation, thestoring request.
This standard is suitable to drinks and its fills with the native orewater seepage water source installs the product.
2nd, quotation standard
GB7718 food label general standard
GB/T8538 drinks with the native ore water seepage inspectionprocedure
3rd, terminology and definition
3.1 drinks with native ore water seepage drinking naturalmineral water
Naturally gushes out from the underground deep place or afterthe artificial exposition, not the underground mineral water whichpollutes; Includes a quota the mineral salt, the trace element or thecarbon dioxide gas; In the usual situation, its chemical composition,the current capacity, the water temperature and so on dynamic to arestable in the natural undulation scope internal phase.
4 specifications
4.1 water sources appraisals
4.1.1 water sources places
4.1.1.1 must carry on the regional geology investigation(scale 1:50000-1:200000) and the water source synthesis geology -hydrology geological investigation (scale 1:5000-1:25000).
4.1.1.2 must have the mineral water ɺ??hole) the structurestick plot (the scale 1: 200-1: 1,000) or spring actual geologysectional drawing (scale 1: 1,000).
4.1.1.3 must have above a hydrology year the water temperature, thewater volume, the water level (pressure) ?ض? condition monitormaterial. The water temperature is smaller than 25 ?样ater sources,each month observes time.
4.1.1.4 pumps when the mineral water its water volume, the watervolume, the water level should maintain stably, the water level doesnot have to appear the irreversible drop. The water temperature rangeof variation does not surpass ?? ?殊4.1.1.5 passes through abundantly, is even, the dry season (samplinggap is four months) the water quality examination, its main component(soluble total solid, K +, Ca +, Mg2 +, HCO3 -,
SO42 -, CL -) the content range of variation should notsurpass 20%, all water quality examination result, its ɼД boundarytarget (actual value) must conform to table 2 requests.
4.1.1.6 by the dry season water volume water source permission miningquantity, allows the mining quantity to be supposed every day to bebigger than 50t.
After 4.1.1.7 water sources developments, must carry on thewater quality, the water volume, the water level, the watertemperature long-term monitor.
4.1.1.8 water sources appraisals report material should conform toappendix A (reference) to request.
4.1.2 water sources health protection
4.1.2.1 water sources must set up the hygienic zone ofprotection, in zone of protection establishment fixed sign.
The country engineering supervision bureau 1995-08-17 authorizes1996-08-01 implementation
4.1.2.2 hygienic zones of protection must conform to thefollowing requirement, and has the hygienic zone of protection chart(the scale 1: 5000-1: 10,000).
4.1.2.2.1 first area is the strict protectorate. In the spring (well)in the periphery radius 15m scope, the irrelevant personnel enters.Does not have to revolve with takes other goods which the waterequipment has nothing to do with.
4.1.2.2.2 second area is a restricted sector. In the mineral waterwater source, the productive area periphery are not smaller than inthe 30m scope, does not have to establish the community and thefactory, the restroom, the water hole, does not have to pile up trash,the waste residue or lays down the sewage conduit. Strictly prohibitsthe use agricultural chemicals, the chemical fertilizer, and must nothave the destruction water source area hydrogeological conditions theactivity.
4.1.2.2.3 third area for supervisory area. Its scope should decidesaccording to the water source military supplies and the distribution,causes the water source to exempt is polluted.
4.2 water quality
4.2.1 sense organs requests
The sense organ should conform to table 1 stipulation
