Chubbuck Water Quality Summary: 2000
CITY OF CHUBBUCK
We are pleased to present a summary of the quality of the water provided to you during the past year as a part of the 1996 Safe Drinking Water Act (SDWA) requirements that water utilities issue an annual "Consumer Confidence" report to customers. This report is based upon tests conducted by the City of Chubbuck Public Works Department.

The table below shows the results of our water quality monitoring for the period January 1, 1999 to December 31, 1999. 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. We have included test results for only those constituents found in our drinking water. Most constituents tested for were not found.

Microbiological Contaminants
1. Total Coliform Bacteria N
0
0
 0 0 10 samples per month Naturally present in the environment. Coliforms are bacteria which are naturally present in the environment and are used as an indicator that other, potentially harmful bacteria may be present.
2. Fecal Coliform and E. coli N 
0
0
 0 0 Tested only when Total Coliform detected Human and animal fecal waste. Fecal coliform and E. Coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, and people with severely compromised immune systems.
Radioactive Contaminants
3. Beta/photon emitters (only required for systems with populations of 100,000 and over) N
50 pCi/l
0 pCi/l 
 4.6 8.9 8/97 Decay of natural man-made deposits. Certain minerals are radioactive and may emit forms of radiation known as photons and beta radiation. Some people who drink water containing beta and photon emitters in excess of the MCL over many years have an increased risk of getting cancer.
4. Gross Alpha Activity 

(Alpha emitters)

 N
15 pCi/l
0 pCi/l
 6.5 10.5 8/97 Erosion of natural deposits. Certain minerals are radioactive and may emit a form of radiation known as alpha radiation. Some people who drink water containing alpha emitters in excess of the MCL over many years may have an increased risk of getting cancer.
5. Radium 226/228 combined (pCi/l) N
5 pCi/L
0 pCi/L
 0.0 0.4 8/97 Erosion of natural deposits. Some people who drink water containing radium 226 or 228 in excess of the MCL over many years may have an increased risk of getting cancer.
Inorganic Contaminants
6. Arsenic  N
50 ppb
N/A
 5 13 09/99 Erosion of natural deposits. Runoff from orchards. Runoff from glass and electronic production wastes. Some people who drink water containing Arsenic in excess of the MCL over many years could experience skin damage or problems with their circulatory system, and may have an increased risk of getting cancer.
7. Asbestos  N
7 MFL
7 MFL
 ND ND 03/94 Decay of asbestos cement water mains. Erosion of natural deposits. Some people who drink water containing asbestos in excess of the MCL over many years may have an increased risk of developing benign intestinal polyps.
8. Barium N
2 ppm
2 ppm
 0.12 0.18 09/99 Discharge of drilling wastes. Discharge from metal refineries. Erosion of natural deposits. Some people who drink water containing barium in excess of the MCL over many years could experience an increase in their blood pressure.
9. Chromium N
0.1 ppm
0.1 ppm
 .003 .003 09/99 Discharge from steel and pulp mills. Erosion of natural deposits. Some people who use water containing chromium well in excess of the MCL over many years could experience allergic dermatitis.
10. Copper N
1.3 ppm
1.3 ppm
 .12 .59 12/97 Corrosion of household plumbing systems. Erosion of natural deposits. Leaching from wood preservatives. Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short time could experience gastrointestinal distress. Some people who drink water containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson’s Disease should consult their doctor.
11. Fluoride N
4 ppm
4 ppm
 0.12 0.18 09/99 Erosion of natural deposits. Water additive, which promotes strong teeth. Discharge from fertilizer and aluminum factories. Some people who drink water containing fluoride in excess of the MCL over many years could get bone disease, including pain and tenderness of the bones. Children may get mottled teeth.
12. Lead N
15 ppb
0
 ND 6.4 12/97 Corrosion of household plumbing systems. Erosion of natural deposits. Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.
13. Nitrate N
10 ppm
10 ppm
 3.05 5.73 09/99 Runoff from fertilizer use. Leaching from septic tanks, sewage. Erosion of natural deposits. Infants below the age of six months who drink water containing nitrate in excess of the MCL could become seriously ill and, if untreated, may die. Symptoms include shortness of breath and blue baby syndrome.
Volatile Organic Contaminants
14. Tetrachloroethylene N
5 ppb
0 ppb
 ND 2.7 Quarterly during 1999 Leaching from PVC pipes. Discharge from factories and dry cleaners. Some people who drink water containing tetrachloroethylene in excess of the MCL over many years could have problems with their liver, and may have an increased risk of getting cancer.
