Methodology

Inductively Coupled Plasma Optical Emission Spectrometry - is an American Industrial Hygiene Association (AIHA) environmental Lead accreditation for the analysis of soils, dust wipes and paints. This accreditation is accepted by the National Cooperation for Laboratory Accreditation (NCLA).

Specimen Collection

Water - Samples must be submitted by an Environmental Public Health Specialist or Environmental Specialist employed by a public health agency.

Water samples should have at least 500 milliliters in a one-liter plastic collapsible container. The samples must be shipped as soon as possible after collection so that it arrives within one week of collection.

Paint, dust wipes or soil - Samples must be submitted by a Licensed Lead Risk Assessor.

Paint samples should contain the equivalent of a 3- inch square piece of paint and be placed in the provided bag.

Soil samples should have at least 400 grams and be placed in the provided bag.

Dust wipe samples must be collected in the certified lead-free tubes provided by the State Public Health Laboratory.

Dust wipe samples must have a field blank submitted with each set of samples. The sample set will be rejected if a field blank is not submitted or labeled.

All environmental lead samples must be submitted in collection devices provided free of charge by the State Public Health Laboratory to the Licensed Lead Risk Assessor. To request collection devices contact us.

These measures provide several quality assurances, including guarantees that collection devices do not contain detectable amounts of lead.
