QA/QC
Delta's Quality Assurance (QA) program is
appropriately designed to the needs of Delta
management and clients to ensure that data of
known and defensible quality is produced and that
the accuracy of the analytical results can be stated
with a high level  of confidence. Delta 's QA program
is formulated such that an audit review of its
implementation will enable a reviewer to determine
whether or not the QA program is being managed
such that it guarantees high quality as well as
meaningful and accurate data. The format adopted
for Delta QA program is the one recommended by
QAMS-004/80, QAMS-005/80, ORD and QAA
guidelines. The QA objectives are to assure that
representative data are generated, and are, Precise,
Accurate, Reliable, Meaningful and Admissible as
Legal Evidence.

Delta Quality Control system includes the use of
calibration blank and standards; method blank,
continuous calibration check,matrix spiked and matrix
spiked duplicates, sample and sample duplicates and
Laboratory control samples. EPA reference sample
is routinely used to check the performance of the
analytical system.  Field blank and trip blank are
optional and will be  included upon client request. The
QA/QC data package includes a blank, spike level,
Matrix spiked and Matrix spike duplicate percent
recovery, sample/sample duplicate and RPD
(Relative percent differences),  percent recovery of
Laboratory Control Sample and /or surrogates .The
format of the reports are tailored to satisfy the
client's need.

All data generated are appropriately documented,
will be reviewed by the chemist, QAO, and
Laboratory Director and are presented in standard
units to allow comparison with other data. All the
information regarding a particular sample will be
accessible through our LIMS (Laboratory Information
Management System).
