Nature of Requirements:
Title: SEMIPERMEABLE MEMBRANE DEVICE (SPMD)ITEMS

1. Purpose of an Advance Contract Notice (ACAN)
An ACAN is a public notice indicating to the supplier community
that a department or agency intends to award a contract for
goods, services or construction to a pre-identified supplier,
thereby allowing other suppliers to signal their interest in
bidding, by submitting a statement of capabilities. If no
supplier submits a statement of capabilities that meets the
requirements set out in the ACAN, on or before the closing date
stated in the ACAN, the contracting officer may then proceed
with the award to the pre-identified supplier.

2. Definition of Requirement
The Department of Environment Canada has a requirement for a
Standing Offer for the the supply and delivery to various
destinations in Canada of Semipermiable Membrane Device (SPMD)
items including:
SPMD Cannisters
SPMD Films with Performance Reference Spikes on Spiders
Replacement Spiders
SPMD Film Blanks

Background and SPMD Description
Environment Canada is a partner in the Integrated Monitoring
Plan for the Oil Sands. Under this Plan, Environment Canada is
required to engage in water quality monitoring, including the
use of time-integrative passive sampling devices. SPMDs are
specifically listed as a required monitoring tool for lipophilic
pollutants such as Polycyclic Aromatic Compounds, in the Lower
Athabasca Water Quality Monitoring Plan Phase 1, page 30
(Environment Canada and Alberta Environment, 2011a).
Performance Reference Compounds are also specifically listed as
requirements for SPMD passive sampling tools. SPMDs are
currently deployed at a number of mainstem Athabasca sampling
stations, and are to be implemented as monitoring tools in
Athabasca tributaries, and also in wetlands of the
Peace-Athabasca Delta, as per the expanded geographic extent
monitoring plan (Environment Canada and Alberta Environment
2011b).

The triolein-filled SPMD provided by EST Labs is a unique
product, designed and patented to provide a controlled and
repeatable absorption of lipophilic substances dissolved in
water. The passive transport mechanism of these devices is
similar to fish gills or lungs. The product was originally
designed by the U.S. Geological Survey, and has been on the
market and supported by a research and development background of
better than 20 years. Only SPMDs are directly linked to
specific USGS Guidelines for Use and "Estimated Water
Concentration Calculator" spreadsheets. SPMDs are a widely
accepted product, used around the world for monitoring
applications.

The unique aspect of SPMDs is that, with the performance
reference compounds (PRC's) spiked into the triolein matrix, the
contents of the SPMD can be related directly back to the
concentration of substances in the water over the deployment
time.

The Semipermeable Membrane Device (SPMD) is composed of
additive-free low density polyethylene tubing containing a thin
film of a 99% pure, triolein. The polymer contains transport
corridors of less than 10 Å in diameter, allowing for the
selective diffusion of hydrophobic organic chemicals, which are
then held in the triolein (absorption rather than adsorption).
The SPMD sampler, in conjunction with appropriate, sensitive
analytical techniques, allows achievement of accurate,
reproducible data in the parts per quadrillion level.

Environmental factors such as water flow, temperature, and the
buildup of a biofilm on the sampler's surface can affect the
rate at which chemicals are sampled. These factors are
site-specific and can greatly reduce the accuracy of the
estimated water concentrations. To account for these effects,
the performance reference compound (PRC) approach was developed
(Huckins et al, 2002). Using models previously developed
(Huckins et al, 2006), the average water concentrations of
selected chemicals can be estimated using PRC loss data,
chemical sampling rates (when available), and amounts of
chemicals sampled. For SPMDs, regression models have been
created which estimate a chemical's site specific Rs and its Cw
based on the log Kow of the chemical, the PRC's release rate
constant (ke) and SPMD-water partition coefficient (Ksw)
(Huckins et al, 2006).

In addition to adding PRCs to the triolein matrix within SPMDs,
it is common to add a photolysis surrogate, a chemical that can
degrade upon exposure to sunlight but has a low fugacity,
therefore, it will not be lost because of diffusion out of the
SPMD during the field exposure. This allows the effect of
photolysis degradation on compounds of interest to be estimated
for the contents of the SPMDs, producing a more accurate result.
Other types of membrane devices that do not contain triolein
cannot be "spiked" with either Performance Reference Compounds
or photolysis surrogate.

SPMDs from EST Labs are designed to work with standard USGS
"Estimated Water Concentration Calculator" spreadsheets, to
calculate the estimated water concentration from SPMD data.
This is a critical aspect of this product, allowing the
time-integrative sampling tool to be directly linked to the
amount of substances dissolved in the water during the
deployment period.

In Addition, EST Labs provides their SPMD films already
stretched on deployment "spiders" or carriers, and sealed in
cans filed with argon gas, to ensure that no contamination of
the films happens during shipment and transport. Films that
must be stretched by the field technicians would be subject to
greatly increased potential for contamination. EST Labs
provides stainless steel deployment canisters that the "spiders"
are designed to fit quickly and efficiently into, reducing
handling time and the potential for contamination in the field
during deployment.
