The regulatory level for total cresol under the RCRA Toxicity Characteristic rule is

The regulatory level for total cresol under the Resource Conservation and Recovery Act (RCRA) Toxicity Characteristic rule is established at 200 mg/l. This specific concentration is important because it defines the threshold for determining whether a waste material exhibits toxicity and thus should be classified as hazardous waste. When the concentration of total cresol in a waste exceeds this regulatory level, the waste must be handled and treated according to RCRA guidelines, which are designed to protect human health and the environment from the risks associated with hazardous substances.

Understanding this limit is crucial for environmental health specialists and sanitarians as they evaluate waste materials, ensuring that proper disposal methods are used to mitigate risks associated with toxic substances.
