| DibromomethaneDibromomethane is an unregulated byproduct of tap water disinfection and a manufactured chemical used in chemical synthesis and as an ingredient in fire extinguishing fluids. | 0 ppb 0 ppb | No | 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. | ||||
