'�... ,.001 <br />Page 3 <br />Ms. Margaret Lagorio <br />January 18, 1994 <br />The monitoring wells will be developed by surging, swabbing, and pumping <br />until a non -turbid discharge is obtained. Development water will be contained <br />and sealed in 55 -gallon barrels at the site pending proper disposal. The new <br />monitoring wells will be surveyed relative to the arbitrary datum established <br />for the existing well network. <br />Selected soil and groundwater samples will be submitted to a state -certified <br />laboratory for analysis. Laboratory testing will include total petroleum <br />hydrocarbons as gasoline (TPH-g using Method 8015-m), and benzene, <br />toluene, ethylbenzene, and xylenes (BTEX using Method 8020). A number of <br />other chemical and physical tests will be performed on certain soil and <br />groundwater samples to evaluate possible remedial alternatives. The chemical <br />tests include total organic carbon, nitrates/nitrites, phosphates, pH, alkalinity, <br />total suspended solids, acidity, iron, calcium, and magnesium. Physical tests <br />includes permeability and grain size analysis. <br />Following the completion of the field work and the sample testing, Burlington <br />will prepare a report for the SJCEHD summarizing our activities and results. <br />Burlington is currently awaiting competitive cost estimates from licensed <br />drillers to perform the monitoring well installations. Once a driller has been <br />chosen, Burlington will submit the appropriate well permit application and fee <br />to the SJCEHD. <br />If you have questions regarding this workplan addendum, or require additional <br />information, please call Mark Milward (Burlington) at (618) 281-7173. <br />Sincerely yours, <br />BU�RL�INNGTON ENVIRONMENTAL INC. <br />Mark F.
