CASE NARRATIVE

Report ID: S1406226006

(Replaces S1406226005)

Samples MAR1SOIL-01-15, MAR1SOIL-01-30, MAR1SOILA-01-5, MAR1SOILB-01-5, MAR1SOILC-01-5, MAR2SOIL-01-15, MAR2SOIL-01-30, MAR2SOILA-01-5, MAR2SOILB-01-5, MAR2SOILC-01-5, MAR3SOIL-01-15, MAR3SOIL-01-30, MAR3SOIL-02-15, MAR3SOILA-01-5, MAR3SOILB-01-5, MAR3SOILC-01-5, MAR4SOIL-01-15, MAR4SOIL-01-30, MAR4SOILA-01-5, MAR4SOILB-01-5, MAR4SOILC-01-5, MAR5SOIL-01-15, MAR5SOIL-01-30, MAR5SOILA-01-5, MAR5SOILA-02-5, MAR5SOILB-01-5, and MAR5SOILC-01-5 were received on June 11, 2014.

All samples were received and analyzed within the EPA recommended holding times, except those noted below in this case narrative. Samples were analyzed using the methods outlined in the following references:

"Standard Methods For The Examination of Water and Wastewater", approved method versionsTest Methods for Evaluating Solid Waste, Physical/Chemical Methods, SW-846, 3rd Edition40 CFR Parts 136 and 14140 CFR Part 50, Appendices B, J, L, and OMethods indicated in the Methods Update Rule published in the Federal Register Friday, May 18, 2012ASTM approved and recognized standards

All Quality Control parameters met the acceptance criteria defined by EPA and Inter-Mountain Laboratories except as indicated in this case narrative.

CASE NARRATIVE

Report ID: S1411189001

Samples MARSS-01-01, MARSS-02-01, MARSS-03-01, MARSS-04-01, MARSS-04-02, MARSS-05-01, MARSS-06-01, MARSS-07-01, MARSS-08-01, MARSS-09-01, MARSS-10-01, MARSS-10-02, MARSS-11-01, MARSS-12-01, MARSS-13-01, MARSS-14-01, MARSS-15-01, MARSS-16-01, MARSS-17-01, MARSS-18-01, MARSS-19-01, MARSS-20-01, MARSS-21-01, MARSS-22-01, and MARSS-23-01 were received on November 13, 2014.

All samples were received and analyzed within the EPA recommended holding times, except those noted below in this case narrative. Samples were analyzed using the methods outlined in the following references:

"Standard Methods For The Examination of Water and Wastewater", approved method versionsTest Methods for Evaluating Solid Waste, Physical/Chemical Methods, SW-846, 3rd Edition40 CFR Parts 136 and 14140 CFR Part 50, Appendices B, J, L, and OMethods indicated in the Methods Update Rule published in the Federal Register Friday, May 18, 2012ASTM approved and recognized standards

All Quality Control parameters met the acceptance criteria defined by EPA and Inter-Mountain Laboratories except as indicated in this case narrative.
