WATER SYSTEM INFORMATION:
This report shows our water quality and what it means. If you have any questions about this report or concerns about the quality of your water, please contact Rick McKnight at 772-3251. We want you to be informed about your water supply. If you want to learn more, please attend any of our regularly scheduled meetings. They are held on the third Monday of the month at 7:00 at the Ridgway Borough Municipal Building.
SOURCE(S) OF WATER:
Our source is surface water from H.B. Norton Dam located on Big Mill Creek in the Allegheny National Forest. Because of it’s remote location there is very little contamination.
Some people may be more vulnerable to contaminants in drinking water than the general population. 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, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidiumand other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).
MONITORING YOUR WATER:
We routinely monitor for contaminants in your drinking water according to federal and state laws. A Source Water Protection Plan was also done in 2012. The following tables show the results of our monitoring for the period of January 1 to December 31, 2019. The State allows us to monitor for some contaminants less than once per year because the concentrations do not change frequently. Some of our data is from prior years in accordance with the Safe Drinking Water Act. The date has been noted on the sampling results table.
Action Level (AL) – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Maximum Contaminant Level (MCL) – 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 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.
Maximum Residual Disinfectant Level (MRDL) – The highest level of a 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 drinking water 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 contaminants.
Minimum Residual Disinfectant Level (MinRDL) – The minimum level of residual disinfectant required at the entry point to the distribution system.
Treatment Technique (TT) – A required process intended to reduce the level of a contaminant in drinking water.
ppm = parts per million, or milligrams per liter (mg/L)
ppb = parts per billion, or micrograms per liter (μg/L)

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 run-off, 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 by-products 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.
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline(800-426-4791).
Information About Lead:
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. Ridgway Borough Water System 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 the EPA website.
The Ridgway Borough had a TOC sample that was submitted late and was tested fine by the contracted lab. Last year, as in years past, your tap water met all EPA and state drinking water health standards.

Reporting Requirements Not Met for: Ridgway Borough
Our water system failed to report drinking water standard results on time over the past year. Even though these were not emergencies, as our customers, you have a right to know what happened and what we did to correct these situations.
We are required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health standards. During December of 2019 we did not sample the following contaminant on time. However, all the results reported late met the drinking water standards.
What should I do? There is nothing you need to do at this time.
The table below lists the contaminant(s) we did not properly report on time and the results of these samples.
|Contaminant||Required sampling frequency||Number of samples taken||When all samples should have been taken||Sample Results|
|TOC (RAW)||Quarterly||1||Dec. 7, 2019||100% compliant|
|TOC (FINISH)||Quarterly||1||Dec. 7, 2019||100% compliant|
|Alkalinity||Quarterly||1||Dec. 7, 2019||100% compliant|
What happened? What was done? Samples were collected at a later date and were in compliance. For more information, please contact Ridgway Borough at 814-772-3251 .
Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
