What Do The Following Tables Mean?
The tables in this report show the results of our water-quality analyses for January 1 to December 31, 2021. Every regulated contaminant that we detected in the water, even in the most minute traces, is listed here. The table contains the name of each substance, the highest level allowed by regulation (MCL), the ideal goals for public health, the amount detected, the usual sources of such contamination, footnotes explaining our findings, and a key to units of measurement. The State allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representative, are more than one year old. Although we ran many tests, only the listed substances were found. They are all below the MCL required. We are pleased to report that your drinking water meets or exceeds all Federal and State requirements.
The following abbreviations and definitions are important:
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 that is 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.
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.
Key To Contaminant Lists:
| NTU = | Nephelometric Turbidity Units (a measure of water clarity) | N/A = | Not Applicable |
| ppb = | parts per billion, or micrograms per liter (µg/l) | ppm = | part per million, or milligrams per liter (mg/l) |
| MinRDL= | minimum level of residual disinfectant required at the entry point to the distribution system | WTP = | Water Treatment Plant |

Unregulated Contaminant Monitoring Rule (UMCR):
Unregulated contaminants are those for which the EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. In addition to testing we are required to perform, our water system voluntarily tests for hundreds of additional substances and microscopic organisms to make certain our water is safe and of high quality. If you are interested in a more detailed report or have any questions about the West View Water Authority and our water quality, contact Mark Valenty, Environmental Compliance Coordinator, at (412) 931-3292.

Additional Testing:
Volatile Organic Compounds (VOCs): No VOCs were detected during the 2021 reporting year at either WTP.
Synthetic Organic Compounds (SOCs): No SOCs were detected during the 2021 reporting year at either WTP.
Radiological Analysis: Radiological Analysis was conducted during the 2020 reporting year at both WTPs, resulting in non-detects for all parameters.
We are pleased to report that our water system complied with all drinking water standards in 2021.
