Designation:D402518Standard Practice forReporting Results of Examination and Analysis of DepositsFormed from Water for Subsurface Injection1This standard is issued under the fixed designation D4025;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice covers the manner in which the variousresults of examination and analysis to determine the composi-tion of deposits formed from water for subsurface injection areto be reported.1.2 All analyses shall be made in accordance with the testmethods of ASTM,unless otherwise specified.NOTE1While reporting of inorganic constituents in water-formeddeposits as specified in Practice D933 is sufficient for certain industries,this practice provides for the reporting of organic and biological materialsas well as inorganic constituents.NOTE2Consistent with practices in industries where subsurfaceinjection of water is practiced,reporting includes specifying of inorganicconstituents as probable molecular combinations of the species for whichanalyses are performed.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D887 Practices for Sampling Water-Formed DepositsD932 Practice for Filamentous Iron Bacteria in Water andWater-Formed DepositsD933 Practice for Reporting Results of Examination andAnalysis of Water-Formed DepositsD1129 Terminology Relating to WaterD4412 Test Methods for Sulfate-Reducing Bacteria in Waterand Water-Formed DepositsE29 Practice for Using Significant Digits in Test Data toDetermine Conformance with Specifications3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this standard,refer toTerminology D1129 and Practices D887.4.History of Sample4.1 Information regarding the source and history of thesample shall be included in the report of the analysis.Thisinformation should be that supplied by the individual submit-ting the sample as follows:4.1.1 Name of company supplying the sample,4.1.2 Name of location of plant,facility,and well,4.1.3 Date and time of sampling,4.1.4 Number of sample,4.1.5 Name and other designation of equipment from whichsample was removed,4.1.6 Precise location from which sample was removed,4.1.7 Operating temperature and pressure of water or brineat location of deposit,4.1.8 Type of treatment applied to the water that formed thedeposit,4.1.9 An account of system operating conditions that mayhave contributed to deposition(for example,filter channeling,chemical pump outage,or increased system temperature),4.1.10 Appearance and extent of deposit prior to removal,4.1.11 Exact method that was used in removing the sampleand notes concerning any contamination that might haveoccurred during the process,4.1.12 Specific methods used for preservation of sampleprior to and subsequent to removal,4.1.13 Results of field tests made on the sample or relatedequipment,1This practice is under the jurisdiction of ASTM Committee D19 on Water andis the direct responsibility of Subcommittee D19.05 on Inorganic Constituents inWater.Current edition approved May 1,2018.Published May 2018.Originallyapproved in 1981.Last previous edition approved in 2013 as D4025 08a(2013).DOI:10.1520/D4025-18.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 4.1.14 An analysis of the water from which the deposit wasformed,and4.1.15 Identity of sampler.5.Significance and Use5.1 This practice sets down the manner in which dataobtain
