Abstract:  THE NORTHERN ENGRAVING CORPORATION (NEC), LOCATED IN SPARTA, WISCONSIN, PRESENTLY OWNS AND OPERATES A MANUFACTURING FACILITY AT THE SITE, WHICH PRODUCES METAL NAME PLATES, DIALS AND DECORATIVE TRIM FOR THE AUTOMOTIVE INDUSTRY. THE MAJORITY OF THE LAND WITHIN THE SPARTA AREA IS ZONED FOR GENERAL AGRICULTURE WHICH INCLUDES LIVESTOCK RAISING, NURSERY, GREENHOUSE AND POULTRY FARMING. FOUR SEPARATE AREAS OF CONTAMINATION AT THE NEC FACILITY HAVE BEEN IDENTIFIED AS POTENTIAL SOURCES OF SOIL, GROUND WATER AND SURFACE WATER CONTAMINATION. THEY INCLUDE THE SLUDGE LAGOON, SEEPAGE PIT, SLUDGE DUMP SITE AND LAGOON DRAINAGE DITCH. THE CHEMICAL CONSTITUENTS FOUND IN THESE AREAS ARE FROM PAST WASTEWATER TREATMENT AND DISPOSAL PRACTICES EMPLOYED AT THE SITE. SINCE THE 1960S WASTE RINSE WATERS AND BY-PRODUCTS OF THE METAL FINISHING PROCESS HAVE BEEN TREATED ONSITE. AN ONSITE WASTEWATER TREATMENT LAGOON WAS INSTALLED IN 1967. RINSE WATER FROM THE PLANT WAS COLLECTED AND TREATED WITH SODIUM HYDROXIDE FOR PRECIPITATION TO METAL HYDROXIDE SOLIDS. THE TREATED RINSE WATER WAS DISCHARGED TO THE SLUDGE LAGOON TO ALLOW SOLIDS TO SETTLE. THE TREATED LAGOON EFFLUENT WAS DISCHARGED TO THE LACROSSE RIVER BY WAY OF A STORM DRAINAGE DITCH. BETWEEN 1968 AND 1976 THE SLUDGE LAGOON ACCUMULATED SOLIDS FROM THE TREATED WASTEWATER. ON TWO OCCASIONS, SLUDGE WAS REMOVED FROM THE LAGOON AND LANDFILLED IN AN ONSITE DUMP AREA. THE SLUDGE LAGOON WAS EVENTUALLY REMOVED FROM SERVICE IN 1980, BY WHICH TIME TWO TO FOUR FEET OF METAL HYDROXIDE SLUDGE HAD ACCUMULATED ON THE BOTTOM OF THE LAGOON AND PRESENTLY REMAINS. AN ONSITE SEEPAGE PIT WAS EMPLOYED TO NEUTRALIZE SPENT ACID WASTE. IT WAS REMOVED FROM SERVICE, FILLED WITH APPROXIMATELY FIVE FEET OF CLEAN FILL AND GRADED IN 1981. A NEW ABOVE ONSITE GROUND WASTEWATER TREATMENT SYSTEM WAS INSTALLED IN 1976 AND MODIFIED IN 1984 TO MEET MORE STRINGENT STATE EFFLUENT STANDARDS. APPROXIMATELY 900 YD3 OF SLUDGE IS CONTAMINATED WITH PHOSPHORUS, ALUMINUM, CADMIUM, COPPER, NICKEL, IRON AND FLUORIDE. THE DRAINAGE DITCH IS CONTAMINATED WITH TRICHLOROETHYLENE (TCE); AND GROUND WATER IS CONTAMINATED WITH COPPER, NICKEL AND ZINC.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES; EXCAVATION AND ONSITE SOLIDIFICATION OF APPROXIMATELY 4,400 YD3 OF SLUDGE AND SOIL; INSTALLATION OF A RCRA COVER ATOP THE LAGOON; APPLICATION OF ACCESS AND DEED RESTRICTION TO THE SEEPAGE PIT PROPERTY; AND GROUND WATER MONITORING. THE ESTIMATED TOTAL CAPITAL COST FOR THIS REMEDIAL ACTION IS $295,000 WITH ANNUAL O&M OF $16,000.
 
Remedy:  A. SOURCE CONTROL
1. EXCAVATE AND PLACE CONTAMINATED MATERIALS FROM THE DRAINAGE DITCH AND SLUDGE DUMP SITE IN THE SLUDGE LAGOON FOR SOLIDIFICATION.
2. ALL CONTAMINATED MATERIALS IN THE SLUDGE LAGOON WILL BE SOLIDIFIED, AND THE LAGOON WILL BE PROVIDED A RCRA COVER AND MONITORED FOR PROPER CLOSURE
3. RESTRICT ACCESS AND APPLY DEED RESTRICTIONS TO THE SEEPAGE PIT PROPERTY.
B. MANAGEMENT OF MIGRATION
GROUND WATER CONTAMINATION WILL BE REGULATED AND MONITORED THROUGH THE USE OF ALTERNATE CONCENTRATION LIMITS (ACLS) TO BE APPLIED DOWNGRADIENT OF THE SLUDGE LAGOON AND THE SEEPAGE PIT. C. OPERATION AND MAINTENANCE THE COVER OVER THE SLUDGE LAGOON AND THE SEEPAGE PIT WILL BE ROUTINELY INSPECTED AND MONITORED. SEMI-ANNUAL GROUND WATER
SAMPLING AND ANALYSES AT COMPLIANCE MONITORING WELLS WILL BE CONDUCTED.
