Roberto,
Attached is a copy of the March cyanide samples for outfalls 005,012, and 013.
Please note the Qualifier Description F1 MS and/or MSD recovery exceeds control limits for outfalls 005 and 013. Both
values were reported at <6 ug/I.
Per our conversation I plan to use the results for the March eDMR.
Please advise if you have any questions.

The test results in this report meet all 2003 NELAC, 2009 TNI, and 2016 TNI requirements for
accredited parameters, exceptions are noted in this report. This report may not be reproduced
except in full, and with written approval from the laboratory. For questions please contact the
Project Manager at the e-mail address or telephone number listed on this page.
This report has been electronically signed and authorized by the signatory. Electronic signature is
intended to be the legally binding equivalent of a traditionally handwritten signature.
Results relate only to the items tested and the sample(s) as received by the laboratory.

Project/Site: Badin NPDES Sampling
Analytical test results meet all requirements of the associated regulatory program (e.g., NELAC (TNI), DoD,
and ISO 17025) unless otherwise noted under the individual analysis. Data qualifiers are applied to note
exceptions. Noncompliant quality control (QC) is further explained in narrative comments.
• QC results that exceed the upper limits and are associated with non -detect samples are qualified but further
narration is not required since the bias is high and does not change a non -detect result. Further narration is
also not required with QC blank detection when the associated sample concentration is non -detect or more
than ten times the level in the blank.
Matrix QC may not be reported if insufficient sample or site -specific QC samples were not submitted. In these
situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD is performed, unless otherwise
specified in the method.
Surrogate and/or isotope dilution analyte recoveries (if applicable) which are outside of the QC window are
confirmed unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g. SDWA, NPDES) must comply with the associated agency
requirements/permits.
Measurement uncertainty values, as applicable, are available upon request.
Test results relate only to the sample tested. Clients should be aware that a critical step in a chemical or
microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of
the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper
techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity,
however, unless sampling has been performed by a member of our staff. Times are local to the area of activity.
Parameters listed in the 40 CFR Part 136 Table II as "analyze immediately" and tested in the laboratory are not
performed within 15 minutes of collection.
This report shall not be reproduced except in full, without the written approval of the laboratory.
WARRANTY AND LIMITS OF LIABILITY - In accepting analytical work, we warrant the accuracy of test results
for the sample as submitted. The foregoing express warranty is exclusive and is given in lieu of all other
warranties, expressed or implied, except as otherwise agreed. We disclaim any other warranties, expressed or
implied, including a warranty of fitness for particular purpose and warranty of merchantability. In no event shall
Eurofins Lancaster Laboratories Environmental, LLC be liable for indirect, special, consequential, or incidental
damages including, but not limited to, damages for loss of profit or goodwill regardless of (A) the negligence
(either sole or concurrent) of Eurofins Lancaster Laboratories Environmental and (B) whether Eurofins
Lancaster Laboratories Environmental has been informed of the possibility of such damages. We accept no
legal responsibility for the purposes for which the client uses the test results. Except as otherwise agreed, no
purchase order or other order for work shall be accepted by Eurofins Lancaster Laboratories Environmental
which includes any conditions that vary from the Standard Terms and Conditions, and Eurofins Lancaster
Laboratories Environmental hereby objects to any conflicting terms contained in any acceptance or order
submitted by client.
