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, 2018.  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 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 microbes.

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

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 the 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 West View Water Authority and our water quality, contact Scott McNicol, West View Water Authority Production Manager, at (412) 931-3292.

Additional Testing:

Volatile Organic Compounds (VOCs): No VOCs were detected during the 2018 reporting year.

Radiological Analysis: Radiological Analysis was conducted during the 2011 reporting year, resulting in non-detects for all parameters.

 

Violations:

We delivered our 2017 CCR to our customers by July 1, 2017; however, we submitted our final 2017 CCR to the DEP after their July 1, 2017 deadline.  The DEP was consulted during the preparation of the 2017 CCR which was subsequently submitted to them in its final form, returning us to compliance.

 

There were 12 additional violations this past year related to reporting.  Samples were taken correctly at the required time and reported at the required time by West View Water Authority for turbidity, total alkalinity, and chlorine.  However, several reports included mistakes in nomenclature, dates and/or labels.  When West View Water Authority discovered the mistake and made the appropriate correction in the report, the violation(s) were generated because the corrected report was submitted at a later date than that required for the original sample.  (Specifically, several chlorine samples were mislabeled “C” instead of “D” for distribution, alkalinity was reported as special instead of raw, and July turbidity was mistakenly submitted as August data.)  All of the incorrect reports have been corrected and submitted to the State.  The corrected reports and sampling results indicate the West View Water Authority is meeting drinking water standards and are fully in compliance with the DEP requirements.
