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 mg/l.
* mg/kg (Totals) levels are unofficial and not endorsed by the federal
government. Use as an informational guideline only. Never use totals on a liquid
matrix.
