The charts above list contaminants
detected in Upper Trinity Regional Water District's water.
In each case, the water provided by the Upper Trinity Regional
Water District meets a higher standard than the Safe Drinking
Water Standards established by law. Numerous other tests
for other contaminants were conducted, with none detected.
If you would like a complete list of undetected contaminants,
please call us at (972) 219-1228. |

Definitions: |
|
| Maximum Contaminant
Level: The highest level of a contaminant that is
allowed in drinking water. |
| |
| Maximum Contaminant Level
Goal: The level of a contaminant in drinking water below which
there is no known or expected risk to health. |
| |
| NTU:
Nephelometric turbidity units. The
unit used to measure the turbidity of water. |
| |
|
Treatment Technique: A required process intended to reduce
the level of a contaminant in drinking water. |
| |
| Turbidity: A measure
of water's clarity. How clear the water is can indicate how
many particles are in it. The goal is to produce water with
turbidity levels as low as possible. Turbidity has no health
effect. However, turbidity can interfere with disinfection
and provide a medium for microbial growth.
Excessive turbidity could allow the presence of
disease-causing organisms. Such organisms can cause symptoms
such as nausea, cramps, diarrhea, and associated headaches. |
|
| pCi/L:
Picocuries per liter. A measure of radioactivity in water
equal to 10-12 curies. Quantity of radioactive
material producing 2.22 nuclear transformations per minute. |
| |
|
ppm: Parts per million. One part per million equals one
packet of artificial sweetener sprinkled into 250 gallons of iced
tea. |
| |
|
ppb: Parts per billion. One part per billion is roughly
equal to one packet of artificial sweetener sprinkled into
an Olympic-size swimming pool.
