Aroclor 1242
Aroclor 1242 is a member of the polychlorinated biphenyl (PCB) group of industrial chemicals used as dielectrics, coolants and lubricants in electrical equipment; PCBs contaminate water by leaching from landfills or other waste deposits.Testing Summary

| 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 Aroclor 1242
Health Based Limits for Aroclor 1242
| Standard | Description | Level |
|---|---|---|
| Maximum Contaminant Limit Goal (MCLG) | A non-enforceable health goal that is set at a level at which no known or anticipated adverse effect on the health of persons occurs and which allows an adequate margin of safety. Source: U.S. Environmental Protection Agency. | 0 ppb |
| Maximum Contaminant Limit (MCL) | The enforceable standard which defines the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to health-based limits (Maximum Contaminant Level Goals, or MCLGs) as feasible using the best available analytical and treatment technologies and taking cost into consideration.
