III. HOSPITAL WASTEWATER CHARACTERIZATION STUDY
A
lesson learned in Phase I of the MWRA/MASCO Mercury Work Group
was the importance of facilities knowing the characteristics of
their wastestreams. A wastewater characterization study can help
to identify what and where the sources of mercury are in a
facility. The information obtained from the study can be used to
rank the order in which the sources should be examined for
reduction efforts. The decision to source reduce, segregate,
install pretreatment or implement a combination of these options
to reduce mercury may be easier when wastewater characterization
data is available. The Mercury Work Group views a wastewater
characterization study as an essential component of a successful
mercury reduction program. Therefore, it was decided that before
a Bench-scale Feasibility Testing Project could begin, a
wastewater characterization study had to be performed on the
various medical industry wastestreams.
Such a
study was done by a subgroup of the Phase II Work Group known as
the Wastewater Characterization (WWC) Subgroup. As explained in
Section VI of this document, the Bench-scale Feasibility Testing
Project focused on clinical laboratory wastewater. Therefore,
only clinical wastewater data from the study is included in this
report. The WWC Subgroup report and analytical test results for
the clinical laboratory wastestream are presented in Appendix
B. Data for the other wastestreams (medical research
laboratory, medical waste incinerator, hospital laundry and
steam/power generation) can be obtained from the MWRA on
request.
