Significance and Use
4.1 The test for lead is necessary because it is a toxicant and because there is a limit specified for lead in potable water in the National Interim Primary Drinking Water Regulations. This test serves to determine whether the lead content of potable water is above or below the acceptable limit.
1.1 These test methods cover the determination of dissolved and total recoverable lead in water and waste water by atomic-absorption spectrophotometry and differential pulse anodic stripping voltammetry. Four test methods are included as follows:
Test Method A—Atomic Absorption, Direct
1.0 to 10 mg/L
7 to 15
Test Method B—Atomic Absorption,
100 to 1000 μg/L
16 to 24
Test Method C—Differential Pulse Anodic
1 to 100 μg/L
25 to 35
Test Method D—Atomic Absorption,
5 to 100 μg/L
36 to 44
1.2 Test Method B can be used to determine lead in brines. Test Method D has been used successfully with reagent water, lake water, well water, filtered tap water, condensate from a medium Btu coal gasification process, waste treatment plant effluent, and a production plant process water.
1.3 It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
