Subject Addendum to Revised Benthic Invertebrate Evaluation for the Assabet River W R Grace Superfund Site Acton Massachusetts

Gentlemen

In response to your e-mail of June 28 2004 to Maryellen Johns of WR Grace we are sending you the enclosed information This letter and its attachment serve as an addendum to our report titled Revised Benthic Invertebrate Evaluation for the Assabet River W R Grace Superfund Site Acton Massachusetts dated March 22 2004

On June 17 20041 met Jim Coles of the US Geological Survey (USGS) and Bart Hoskins of the US Environmental Protection Agency (USEPA) on the site to view the benthic invertebrate sampling locations in the Assabet River At that time we discussed the Phgt Meal CharacterizationWater Quality Data Sheets submitted as Appendix A to the March 22 2004 report Based on our discussion these data sheets have been revised and are included as Attachment A to this letter The revised sheets replace Appendix A of the March 22 2004 report

USEPA and MADEP July 13 2004

As requested in your e-mail we are including Habitat Assessment Field Data Sheets - High Gradient Streams (also from reference 1 see footnote 1) for each Assabet River benthic invertebrate sampling location as Attachment B These forms are appropriate for moderate to high gradient streams we believe the Assabet River in the vicinity of the U R Grace site has a moderate gradient The tolerance values that were used in the benthic invertebrate report to calculate the modified Hilsenhoff Biotic Index for each sampling station and that you requested in your e-mail of June 28 2003 are Attachment C to this letter

If you have any questions or comments regarding this information please cull me at 781-782shy6141

Sincerely
