The Township of Randolph’s water system was randomly selected by the USEPA to participate in the UCMR4 monitoring (unregulated contaminants are those that don’t yet have a drinking water standard set by the USEPA). The unregulated contaminants monitoring rule (UCMR4) purpose is to assist the USEPA in assessing which substances may be monitored in the future. Please be aware that the following results are not currently regulated by the USEPA and therefore the maximum containment level (MCL) have not been established.
| Contaminant | Units | MCL | MCLG | Avg. Level Detected | Range |
|---|---|---|---|---|---|
| Dichloroacetic Acid | ug/L | NA | NA | 0.388 | 0.202 to 0.503 |
| Bromochloroacetic Acid | ug/L | NA | NA | 0.428 | 0.346 to 0.478 |
| Dibromoacetic Acid | ug/L | NA | NA | 0.307 | 0.360 to 0.307 |
- Secondary Contaminant: Substances that do not have an impact on health. Secondary contaminants affect aesthetic qualities such as odor, taste or appearance. Secondary standards are recommendations, not mandates.
- Non-detects (ND): Laboratory analysis indicates that the constituent is not present.
- Parts per million (ppm) or Milligrams per liter (mg/L): One part per million corresponds to one minute in two years or a single penny in $10,000.
- Parts per billion (ppb) or Micrograms per liter: One part per billion corresponds to one minute in 2,000 years or a single penny in $10,000,000.
- Maximum Contaminant Level (MCL): The "Maximum Allowed" MCL is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
- Maximum Contaminant Level Goal (MCLG): The "Goal" MCLG is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
- Treatment Technique (TT): A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.
- Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
- Picocuries per liter (pCi/L): Picocuries per liter is a measure of the radioactivity in water.
- Maximum Residual Disinfectant Level (MRDL): The highest level of disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
- Maximum Residual Disinfectant Level Goal (MRDLG): The level of a disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contamination.
- Recommended Upper Limit (RUL): Recommended maximum concentration of secondary contaminants. RULs are recommendations, not mandates.
Overview
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer who have undergone chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. Environmental Protection Agency (EPA)/Centers for Disease Control and Prevention (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline at 1-800-927-6337.
Elevated lead levels, if present, can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The Morris County M.U.A. is responsible for providing high quality drinking water but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking and cooking. If you are concerned about lead in drinking water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline 1-800-927-6337 or at the EPA website.
The following are the potential health effects on children, pregnant women, nursing mothers, and others of the found contaminants listed:
- Alpha emitters: Certain minerals are radioactive and may emit a form of radiation known as alpha radiation. Some people who drink water containing these alpha emitters in excess of the MCL, 15 (PPWS IDCi/L) over many years may have an increased risk of getting cancer.
- Trihalomethanes: Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys or central nervous system, and may have an increased risk of getting cancer.
- HAA5 and TTHM compliance is based on the Locational Running Annual Average (LRAA) calculated at each monitoring location.
