Attached are the results of analyses performed by Gabriel Laboratories on samples recently submitted to our laboratory for examination.

Gabriel Laboratories analyzed samples identified as "China Crete" and "China Tea" for priority pollutants (minus the unlikely parameters of pesticides/herbicides, polychlorinated biphenyls, dioxin, and asbestos). The priority pollutant list is a common and the most extensive listing of regulated analytes.

The paragraphs below are a sumnation of our results and an interpretation of any detectable concentrations. The interpretations are based on hazardous waste limits (land disposal) and Chicago waste water discharge limits (sewer discharges). Greater Chicago sewer limits are used as a guideline although limits may vary between municipalities.

The metals concentration for both samples were either undetectable or slightly above our instruments' detection limits. Only two metals used for hazardous waste classification, one for each sample, were detectable. The leachate concentration would be well below the hazardous waste classification.

The volatile and semi-volatile levels in "China Crete" were not detectable (NO) or below quantitation limit (BQL). The semi-volatiles in "China Tea" were also ND or BQL. The volatile compounds acetone, 2-Butanone (MEK), chloroform, methylene chloride, and styrene were detected in low levels in "China Tea". Concentrations ranged from 815 to 27.8 parts per billion. The

highest concentration, 2-Butanone (MEK), would be well below the USEPA’s hazardous waste classification of 200,000 parts per billion.

The "China Tea" comparison to sewer discharge limits are based on the material being discharged at full strength without dilution water from production'or wash areas.

The pH and Oil & Grease levels are within acceptable ranges for Chicago and other municipalities. The only metals detected in "China Tea" were silver, copper, and zinc. These levels were all less than one part per million and would be acceptable discharge levels for Chicago and other municipalities.

The total amount of "China Tea" volatile organics was 2.063 parts per million. The federal regulatory limit for metal finishers is 2.1 parts per million. Although only slightly below this limit, this comparison is a worst case scenario without the presence of any dilution water.

The "China Crete" comparison to discharge limits is even more difficult since the material is a solid and an aqueous or dilution solution would need to be present in order to discharge the material to a sewer system. It is unlikely that once in solution (provided the solution is not an issue itself) would produce any municipal discharge violations.

Attached we have provided a certified statement regarding our findings. Our interpretations are based on the anticipated use of the materials and do not address a discharge to a body of water (river or lake) either directly or through stormwater run off. Also, our findings are based only on the samples which were submitted and are dependent on their representativeness.
