Quality Control Program

All AESI laboratory analysis are performed following proven standard analysis techniques. To insure quality, AESI has developed a quality control program with the following features.

• Compliance with approved EPA and NIOSH methods for sample collection, preservation, storage, analysis, and disposal.
• Participant in the National Accreditation Program(NVLAP), Proficiency Analytical Testing(PAT) Program, EPA Drinking Water Program, and Environmental Lead Laboratory Accreditation (ELLAP).
• Quaterly participant in profiency rounds administered by the New York Deparment of Health.
• Chain of Custody Record (COCR) is maintained on all samples both during the collection phase of the work and during the in-house analysis.
• Use of statistical parameters, or control charts to monitor accuracy of analysis and overall laboratory effectiveness.
• The foremost analytical instrument available are used for analysis. Instrument Operation have received formal training and are certified through results of performance evaluation samples for their competence to use the analytical instruments.
• Use of reference collection of samples to insure analyst accuracy.
• Monthly audits of mobile laboratory condition and equipment, procedure, project record keeping, and reference material.
• Method reagent blanks are analyzed at a rate of one for every set of samples.
• Matrix spikes are analyzed at a rate of at least one or 5% of the samples in a sample set with same or similar matrix. Each type of matrix in a set is spiked at least once.
• Reagent water blanks are analyzed at a rate of one for every sample set.
• Duplicates samples matrix are analyzed at a rate of 5%^ of the samples in a set.
• Quality Control check samples are analyzed in duplicate at leats twice yearly.
• Completely files are maintained for analytical sample certificates of analysis, reagent certificates, and sample conatiner certificates.
• Complete hard copy of QA.QC files are maintained for customer examination of each analysis.
