5.1 This test method is useful for the determination of element concentrations in many natural waters and wastewaters. It has the capability for the simultaneous determination of up to 29 elements. High sensitivity analysis and larger dynamic range can be achieved for some elements that are difficult to determine by other techniques such as Flame Atomic Absorption.

5.2 The test method is useful for multi-element analysis of domestic and commercial well produced drinking water for metals and nonmetals for use in baseline analysis and monitoring during exploration, hydraulic fracturing, production, closure and reclamation activities related to oil and gas operations (see Guide D8006).

5.2.1 Minimum analyses include arsenic, barium, iron, magnesium, sodium, calcium, manganese, and lead.

5.2.2 Boron, potassium, chromium, selenium, cadmium, and strontium may be required on a site specific basis.

5.2.3 The most abundant elements in oil and gas produced water are sodium, potassium, lithium, magnesium, calcium, strontium, iron, silica, phosphorus, and sulfur.

5.3 The test method is useful for multi-element analysis of acid rock drainage and other major and some trace elements in mining influenced water.

5.4 Where low quantitation limits are required, Test Method D5673 may be applicable.

5.5 The test method is also useful for testing leachates and effluents for ore and mining and metallurgical waste characterization tests including Test Methods D6234, E2242, D5744, and solutions from the Biological Acid Production Potential and Peroxide Acid Generation Methods in the Appendix of Test Methods E1915.
