1 Hazardous waste number.
2 Chemical Abstracts Service number.
3 Quantitation limit is greater than the calculated regulatory level. The quantitation limit, therefore, becomes the regulatory level.
4 If o-, m-, and p-cresol concentrations cannot be differentiated, the total cresol (D026) concentration is used. The regulatory level of total cresol is 200 milligrams per liter.
