AnthraceneAnthracene is a polycyclic aromatic hydrocarbon (PAH) released from fossil fuel combustion, wastewater treatment, waste incineration; it is used to make dyes and plastics and leaches from water distribution system tanks and pipes lined with coal tar.

|Legal at any levelThis is the Federal Limit. State Limits may be lower.|
|NOTE: Each dot in the above graph represents one month.|
* Water utilities are noted as exceeding the legal limit if any test is above the maximum contaminant level (MCL). Most MCLs are based on annual averages so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance.
Health Based and Legal Limits for Anthracene
Health Based Limits for Anthracene
|Health-Based Screening Level||A benchmark concentration of contaminants in water that may be of potential concern for human health, if exceeded. For noncarcinogens, the HBSL represents the contaminant concentration in drinking water that is not expected to cause any adverse effects over a lifetime of exposure. For carcinogens, the HBSL range represents the contaminant concentration in drinking water that corresponds to an excess estimated lifetime cancer risk of 1 chance in 1 million to 1 chance in 10 thousand.
