Appendix A

Bench-Scale Feasibility Testing Project Results - Data Tables

The following tables summarize MWRA Central Laboratory analytical data for raw wastewater samples and for test samples provided by vendors. For each vendor, one table provides mercury concentration data and mercury removal performance (HG-1, HG-2, etc.) based upon analyses performed by the MWRA Central Laboratory.1 Following the mercury tables are Priority Metals data for each vendor (PPM-1, PPM-2, etc.), accompanied by the raw wastewater data of the MWRA Central Laboratory for the samples used for each test. In addition, there are tables comparing vendor analytical data to MWRA Central Laboratory analytical data (C-1, C-2, etc.).

Field names in the tables for vendor data may be inconsistent with the nomenclature used in the vendor reports. The table field names were chosen for consistency to make it easier for the reviewer to understand the steps of the treatment process for each technology. A general explanation of the tables is given below. For information (such as nomenclature) specific to a particular vendor, please refer to the individual vendor reports in Appendix F.

Analytical data for the raw wastewater collected by MWRA. For this test, the MWRA collected two samples for analysis. The two concentration values are averaged for calculation purposes. The concentration data are reported in µg/L (ppb). Analytical data for samples collected after each step of the bench-scale treatment process. Removal pertains to how much pollutant is removed at each step and Total Removal is the total percent removed by the entire process. The concentration data are reported in µg/L (ppb).

Index of Data Tables

NOTE:  The following tables are all in MS Excel 4.0 workbook format.  They are not formatted in HTML, so in order to view them, you must download them to your machine.  To do this in either Netscape or Internet Explorer, click your right mouse button on the link to the file you would like to see (on Macs, hold the mouse button down in the link), and a menu will pop up.  Select "Save As" (or "Save Target As") and select the appropriate drive and folder on your machine to save to.  You may then open the file in Excel.

(Some browsers, such as later versions of Internet Explorer, will open the file directly in the browser window by clicking on the link with the left mouse button).
