This report is provided to inform you about the source and quality of your drinking water, and how it compares to national drinking water standards. This report is a snapshot of last year's water quality. Please take a moment to review this important information.
Romig Park water system is supplied by one well located at the corner of Hillcrest drive and Spenard Road. A connection to the AWWU system provides backup supply. The AWWU water quality report can be viewed at https://www.awwu.biz/water-quality/drinking-water-quality
The source water for Romig Park is quality groundwater, however it does contain slightly elevated levels of Arsenic. In order to lower the level of Arsenic in the system, Romig Park has been blending water from AWWU with the groundwater to reduce the concentration of the Arsenic in the system.
Source waters for Romig Park have been assessed by the Alaska Department of Environmental Conservation for vulnerability to contamination. This assessment determined that the Romig Park source waters have the following vulnerability ratings.
|High Vulnerabilities||Medium Vulnerabilities||Low Vulnerabilities|
|Volatile Organic Chemicals||Bacteria|
|Synthetic Organic Chemicals|
|Other Organic Chemicals|
However, ADEC recognizes that these risk assessments have been derived with data and methodologies that have not been entirely verified and may not accurately estimate your drinking water source vulnerability. This source water assessment is available for review at ADEC and the offices of Northern Utility Services.
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.
Contaminants that may be present in source water include:
- Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
- Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
- Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
- Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
- Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.
In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
Some people may be more vulnerable to contaminants in drinking water than the general population. The following people may be more at risk from infections due to water impurities:
- Immuno-compromised persons such as
- Persons with cancer undergoing chemotherapy
- Persons who have undergone organ transplants
- People with HIV/AIDS or other immune system disorders
- Elderly Persons
These people should seek advice about drinking water from their healthcare providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline
Impurities in the Water
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some impurities. The presence of impurities does not necessarily indicate that water poses a health risk. More information about impurities and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (1-800-426-4791).
To eliminate unnecessary testing expense, the system has applied for and received testing waivers for the following:
An exemption for asbestos testing has been granted due to no asbestos piping in the system. This waiver does not require renewal.
Synthetic Organic Chemicals (SOC)
An SOC waiver was granted in 2016 due to no potential sources of SOC contamination being located within the collection area. Renewal of the waiver is required every 3 years and requires an investigation of the collection area to ensure no sources of contamination exist.
While your drinking water meets EPA’s standard for arsenic, it does contain low levels of arsenic. EPA’s standard balances the current understanding of arsenic’s possible health effects against the costs of removing arsenic from drinking water. EPA continues to research the health effects of low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems.
If present, elevated levels of lead 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. This utility 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 or cooking. If you are concerned about lead in your 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 or at http://www.epa.gov/safewater/lead
Water Quality Testing
Because of the numerous potential sources and varieties of impurities, state and federal law mandates the routine testing for all impurities (over 80) known to pose a risk to public health. Some impurities can affect water sources quickly and others are not expected to vary significantly from year to year. Thus, testing schedules also vary from monthly to once every nine years, depending on risk and the impurity tested. Your water system is routinely monitored for all applicable hazardous impurities. However, of those impurities, only those detected in routine testing are listed in the Detected Impurities table.
|Impurity||Year||Units||MCL||MCLG||Reported Value||Range||Violation||Likely Source|
|Arsenic||2018||µg/L||10||0||8||6.8-8||N||Erosion of natural deposits; runoff from orchards, runoff from glass and electronicsproduction wastes|
|Chlorine (as Cl₂)||2018||ppm||4||4||0.2||0-0.2||N||Water additive used to control microbes|
|Radium 226 and Radium 228 (combined)||2016||pCi/L||5||0||0.049||N/A||N||Erosion of natural deposits|
|Total Trihalomethanes (TTHMs)||2019||ppb||80||N/A||2.6||1.8-3.4||N||Byproduct of drinking water disinfection|
