The <br /> Annual Report discusses the results of the July 2004 monitoring event, activities performed during 2004, <br /> and proposed future activities. The Treatability Report discusses the results of treatability studies using <br /> Hydrogen Releasing Compound®, emulsified soybean oil, chitin, and granular zero valent iron (ZVI) <br /> and a bioaugmentation study using KB-1TM Dechlorinator, a microbial culture. WFS recommends a <br /> Pilot test for the injection of powdered ZVI. <br /> We have the following comments on the Annual Report: <br /> 1. Table 3 of the Annual Report lists detection limits. Some of the detection limits listed are not the <br /> common practical quantitation limit (PQL) for the analytical method listed. The laboratory <br /> selected by WFS must report to the analytical method's PQL that is at or below the action levels <br /> protective of water quality objectives (WQOs). <br /> 2. Tables 4 through 9 of the Annual Report include"MCLS or AL,"which stand for maximum <br /> contaminant levels and action levels, respectively. Some of the action levels listed are not <br /> correct. The Regional Board's WaterQuality Control Plan for the Sacramento River and San <br /> Joaquin River Basins, 4`h Edition (hereafter Basin Plan) designates beneficial uses of the waters <br /> of the State, establishes WQOs to protect these uses, and establishes implementation policies to <br /> implement WQOs. The beneficial uses of the groundwater beneath the site are domestic, <br /> municipal, industrial, and agricultural supply. WQOs listed in the Basin Plan include numeric <br /> WQOs, e.g., state drinking water MCLS that are incorporated by reference, and narrative WQOs, <br /> including the toxicity objective and the tastes and odors objective for surface water and <br /> groundwater. WFS must revise these tables to provide the appropriate numeric limit. On <br /> 1 April 2005, Regional Board staff sent you a letter regarding the WFS Modesto facility. <br /> California Environmental Protection Agency <br /> Q?Recycled Paper <br />
