Dear Contact Person:
We are writing to you on behalf of the Massachusetts Water Resources Authority (MWRA). The MWRA provides water and sewerage service to the Boston metropolitan area. The MWRA operates a 1 billion gallon per day sewage treatment plant. The EPA, state and MWRA have been focusing increased scrutiny on the impacts of mercury discharges into the environment. The MWRA currently prohibits the discharge of mercury from industrial sewer users within the MWRA service area. Mercury is a bioaccumulating toxic that is prohibited from discharge to ensure that the quality of the treated effluent and biosolids (which are converted into fertilizer pellets) meet applicable state and federal regulatory limits. Facilities in theMWRA service area are obliged to comply with MWRA's mercury enforcement limit of 1.0 part per billion (ppb). Many facilities in the MWRA service area have encountered significant difficulties complying with the MWRA mercury limit and have been subject to MWRA enforcement action.
To help address this problem, the MWRA has established a Mercury Products Workgroup to study mercury sources and to reduce the amount of mercury discharged into the MWRA sewer system. This Mercury Workgroup is a unique public/private partnership formed to resolve the issue of mercury noncompliance. The Workgroup is a collaborative process between the MWRA and the regulated community that stresses cooperation to identify and resolve the problem of mercury in facilities' wastewater streams. A subgroup of the Mercury Products Workgroup is the End-of-Pipe Treatment Technology Identification subgroup. The mission of this subgroup is to identify promising pretreatment technologies through a bench testing program to be conducted by the MWRA. Because the enforceable discharge limit is currently 1.0 ppb, we are looking to evaluate technologies capable of pretreating wastewater streams containing between 1.0 - 1,000 ppb mercury.
There are two primary goals to the bench scale testing program :
Identify the performance characteristics of selectedpretreatment technologies using samples of actual wastewater streams. Several different types of wastewater will be used in the bench testing program. The Workgroup has expended a significant amount of effort on characterizing various wastewater streams for conventional and nonconventional pollutants. Upon request, a copy of this wastewater characterization study is available for your review.
Identify interfering matrices in the wastewaters used and the possible solutions to correct for these interferences prior to introducing the mercury containing streams to the pretreatment technology. This step is necessary since some of the wastewater discharges containing mercury are complex, multi-matrix wastewater streams.
We are soliciting your participation in the bench testing program. As a supplier of a mercury pretreatment technology, we are asking for a technical summary of your experience with this pretreatment technology in active applications. This summary should include a description of how the technology works, the concentration levels to which the technology will pretreat and the maximum/minimum concentrations required for the technology to achieve efficient reductions of mercury. The technical summary should also include schematics of the system, the type of mercury removed (ionic, organic, inorganic, complexed, etc.), information on pretreatment required prior to introducing wastewater to the removal technology. We would also like to review analytical data from lab testing and field testing applications of the pretreatment technology. In regard to reporting analytical data, please indicate the minimum detection limit used for all analytical data. The subgroup used a minimum detection limit of 0.2 ppb for all data generated by our wastewater characterization study.
After review of the technical summary, the subgroup would like to invite you to discuss your technology and our planned bench testing program. We also ask for your interest in participating in the bench scale testing.
The results of the subgroup's research findings will be incorporated into a report that will be used to identify promising pretreatment options for facilities operating within the MWRA service area.
We look forward to working with you to identify mercury pretreatment technologies and furthering the goals of the Mercury Workshop initiative. If you are interested in being considered for inclusion in this process, we must receive your written response on or before 8 November 1996. Should you have any questions, please contact Karen Rondeau, Project Engineer, MWRA, at (617) 241-2347.
Sincerely,
W. Schultz, Co-Chair, Technology Identification Subgroup
A. Pollack, Co-Chair, Technology Identification Subgroup
