MERC+GSI – DRAFT Test Plan

Table 1. Ranges of various physical and biological parameters in ambient water during the testing season
(March/April – October/November) in the Port of Baltimore in comparison to ETV/USCG and IMO G8
recommended challenge conditions. Port of Baltimore data collected by MERC and various academic
and agency studies or monitoring efforts in the general location of the
Cape Washington
(Patapsco River).
Ranges in various physical and biological parameters of ambient water during the testing season (July –
September) in the Duluth/Superior Harbor collected by GSI.

Values collected by GSI in 2007 and 2008 as part of facility validations and treatment systems testing
www.nemw.org/GSI/.
For this specific evaluation of the SiCURE treatment system, Siemens Water
Technologies has made a special request to MERC and GSI to augment intake water to more
consistently approach the initial challenge water conditions described in the G8 guidelines during
the test trials. While MERC and GSI do not make any guarantees on the precise conditions of
challenge water, humic acid and Arizona Test Dust (as proposed by ETV and NRL Key West)
will be injected inline during initial filling of control and test tanks at MERC and GSI to increase
TSS, POC and DOC levels, and algae will be added inline to water during filling of control and
test tanks at GSI. Details on these processes are available upon request and will be provided in
the final report.
