water. Have someone translate it for you if needed.)

We are pleased to present our annual water quality report, which covers all testing completed from January

through December 2021. This report is designed to inform you about the quality of water and services we deliver

to you every day. Our constant goal is to provide you with a safe and dependable supply of drinking water. In

addition, we want you to understand the efforts we make to continually improve the water treatment process,

protect our water resources, and our commitment to ensuring the quality of your drinking water. If you would

like to learn more about the Authority, public meetings are held on the third Thursday of each month, 7:00 p.m.,

at 707 South Pike Road.

Source Water Information

The Allegheny River is the main source of supply for the Municipal Authority of Buffalo Township’s service area.

The Stanley K. Swank Freeport Filter Plant is capable of producing 1.25 million gallons of water per day (MGD).

An interconnection with Harrison Township Water Authority also exists in the event of an emergency.

A Source Water Assessment of the Allegheny River near our intake was completed by the PA Department of Environmental Protection (PA DEP).  The Assessment found that the contributing watersheds to the Allegheny River intake are potentially susceptible to contamination by roads, bridges, railroads, boating, barge traffic, auto repair, utility substations/power plants, combined sewer outfalls, pipelines and runoff from non-point sources such as residential development.  A summary report of the Assessment is available online at the Source Water Assessment Summary Reports eLibrary web page:  Copies of the complete report are available for review by calling the PA DEP Northwest Regional Office at (814) 332-6945.

Educational Information

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 can pick up substances resulting from the presence of animals or human activity.

Contaminants that may be present in source water include microbes, organic and inorganic chemicals, radioactive

materials, or pesticides and herbicides. 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 the water poses a health risk. In order to ensure that tap water is safe to drink, the Environmental Protection

Agency (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. More information about contaminants and potential health

effects can be obtained by calling the EPA’s Safe Drinking Water Hotline at 1-800-426-4791.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised

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/Center for Disease Control (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.

Definitions of Terms Used in This Report

AL (Action Level): The concentration of a contaminant, which, if exceeded, triggers treatment or other

requirements, which a water system must follow.

MCL (Maximum Contaminant Level): 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.

MCLG (Maximum Contaminant Level Goal): 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.

MRDL (Maximum Residual Disinfectant Level): 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.

MRDLG (Maximum Residual Disinfectant Level Goal): The level of 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 contamination.

NA: Not applicable

ND: Not detected

NTU (Nephelometric Turbidity Units): Measurement of the clarity, or turbidity, of the water.

ppm (parts per million): One part substance per million parts water, or milligrams per liter.

ppb (parts per billion): One part substance per billion parts water, or micrograms per liter.

SS: Single sample

TT (Treatment Technique): A required process intended to reduce the level of a contaminant in drinking water.

Turbidity - The measurement of the clarity of the water.  Results were below the treatment technique requirement of 0.3 NTU in 95% of all samples taken for compliance on a monthly basis throughout 2021.

%: means percent.

90th Percentile: The highest concentration of lead or copper in tap water that is exceeded by 10 percent of the sites

sampled during a monitoring period. This value is compared to the lead and copper action level (AL) to determine

whether an AL has been exceeded.

Water Quality Results

The Municipal Authority of Buffalo Township routinely monitors for constituents in your drinking water according

to Federal and State Regulations. The following tables show the results of our monitoring for the period of January

1st to December 31st, 2021. If you do not understand the information and have questions concerning these results, or

wish to request a hard copy of this report, please contact Kristy Donaldson, Authority Manager, at (724) 295-2703.




Results were below and exceeded the treatment technique requirement of 0.3 NTU in 95% of all samples taken for compliance on a monthly basis.



Entry Point Chlorine Residual - Measured on Water Leaving the Treatment Plant








Regulated Substances - Measured on Water Leaving the Treatment Plant






Disinfectant Residual - Measured in the Distribution System







Range represents the calculated monthly average of the results for the routine individual samples.

Other Regulated Substances - Measured in the Distribution System












Average results are the highest running annual average for individual sampling points.  Range represents sampling at individual sample points.

Lead & Copper - Measured in the Distribution System

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.  The Municipal Authority of Buffalo Township 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


Cryptosporidium is a microbial pathogen found in surface water throughout the U.S.  Although filtration removes Cryptosporidium, the most commonly-used filtration methods cannot guarantee 100 percent removal.  If the organism was detected, current test methods do not allow us to determine if the organsims are dead or if they are capable of causing disease.  Ingestion of Cryptosporidium may cause cryptosporidiosis, an abdominal infection.  Symptoms of infection include nausea, diarrhea, and abdominal cramps.  Most healthy individuals can overcome the disease within a few weeks.  

Based on the results of the second round of Cryptosporidium monitoring, no additional treatment is required by the US EPA regulations.  


In March 2021, the Municipal Authority of Buffalo Township issued a notification to residence within the area of the Grandview Tank for a violation of the drinking water standard for Total Trihalomethane (TTHM).  The maximum contaminant level (MCL) for TTHM is 80 ppb.  Although our first quarter sample of 2021 was 36 ppb, the running annual average, the running annual average level of TTHM sampled from the Grandview Tank was 81 ppb.  Some people who drink water containing trihalomethanes consistently 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.  The Municipal Authority of Buffalo Township is closely monitoring the situation and operation of the Grandview Tank.
