Montgomery County, Maryland Department of Permitting Services Approves Sorbtive(R)Filter to Protect the Chesapeake Bay from Sediment and Phosphorus

ROCKVILLE, MD, Oct. 19, 2011 /PRNewswire/ – Imbrium(TM)Systems, a Rockville,
Maryland based stormwater treatment solutions company, announced today
that it received an updated approval for Sorbtive(®)Filter by the Montgomery County, Maryland Department of Permitting Services. 
The updated approval is a critical step forward for Imbrium Systems and
Montgomery County in an effort to protect the Chesapeake Bay from the
ravages of non-point source stormwater runoff pollution, at a lower
cost in use to curb stormwater pollution.  SorbtiveFilter is an
industry-leading, fully field-tested treatment system using SorbtiveMedia which captures high volumes of both Total Phosphorus, including high
levels of Dissolved Phosphorus.  Both SorbtiveFilter and SorbtiveMedia
are approved stormwater treatment products by the Maryland Department
of the Environment (MDE).

Under the proposed Chesapeake Bay Total Maximum Daily Load (TMDL), the
Chesapeake Bay will need to shed at least 63 million pounds of nitrogen
and over 3.1 million pounds of phosphorus in order to reach a healthy
stage.  According to statements from the U.S. Environmental Protection
Agency (EPA), the TMDLs – which will soon be implemented throughout the
Chesapeake Bay Watershed – can accommodate 187.4 million pounds of
nitrogen and 12.5 million pounds of phosphorus annually washing off
impervious surfaces in the region.

In a real-world 19-storm event field test conducted following the TARP
protocol, SorbtiveFilter captured over 77% of total phosphorus and 44%
of dissolved phosphorus, in addition to over 80% sediment.  “The
SorbtiveFilter is truly a breakthrough treatment system that offers a
performance validated tool to help the seven states within the
Chesapeake Bay Watershed reduce the amount of phosphorus, nitrogen and
sediment washing into the Bay.  The Montgomery County DPS has always
been a leader in stormwater management, so the department clearly
understands the importance of protecting the Bay from the ravages of
stormwater runoff and phosphorus,” said Scott Perry, Managing Director
at Imbrium Systems.  “Both SorbtiveMedia which is an oxide-coated,
engineered media and the SorbtiveFilter are industry leaders and both
are expected to have a tremendous impact reducing pollutant loads
within the Chesapeake Bay Watershed,” noted Perry.

After years of research and testing, the SorbtiveFilter was introduced
recently as a turn-key stormwater treatment system designed for the
capture of sediment, Total Phosphorus and Dissolved Phosphorus.  It is
already being used to reduce phosphorus loads in several critical
watersheds throughout North America.  SorbtiveMedia is a reactive
engineered granular filter media that retains large pollutant loads and
does not leach pollutants.

“SorbtiveMedia can be used in flexible, green infrastructure designs and
in a wide variety of stormwater treatment practices; including
Environmental Site Design and Low Impact Development applications such
as bioretention cells and infiltration trenches,” noted Edward Kay,
Imbrium Systems’ Regional Manager for Mid-Atlantic and New England.

“SorbtiveMedia is a long-lasting, robust, high-performing enhancement
media that leaves all other media – like sand, perlite and compost – in
its wake.  Many other media types are actually known to leach
nutrients, such as compost.  Our SorbtiveFilter went through the
rigorous review from both the MDE and Montgomery County environmental
officials, and stand-alone approval emerged with their full confidence
in the SorbtiveFilter’s capabilities.  The SorbtiveMedia is a true
breakthrough solution for most stormwater treatment practices on new
and redevelopment projects.  Montgomery County officials recognize that
they can protect the Chesapeake Bay and still promote responsible
economic growth,” concluded Edward Kay.
