Full Description

The US Environmental Protection Agency's requirement that drinking water samples collected for lead analysis be acidified at the time of collection poses two problems: (1) restrictions on mailing nitric acid and (2) safety concerns associated with the possible handling of nitric acid by nontechnical persons. A study was undertaken that showed that acidification could be delayed up to 14 days and that analysis could then be carried out after waiting 28 h, without loss of lead. Includes 5 references, tables.
