Consumer Confidence Report 2004
Big Bend Community Water System
The table below lists all of the drinking water contaminates tested for during the calender year of this report. The presence of contaminates in the
water does not necessarily indicate that the water poses a health risk Unless otherwise noted, the data presented in this table is from testing
done in the calender year of the report. The EPA or the state requires us to monitor for certain contaminates less than once per year because the
concentration of these contaminates do not change frequently.
Important Drinking Water Definitions:
MCLG: Maximum Contaminant Level Goal: The level of a contaminant in drinking water below which there is no known or expected health risk.
MCLGs allow for a margin of safety.
MCL: Maximum Contaminate Level: The highest level of a contaminate that is allowed in drinking water.
MCLs are set as close to the MCLGs as feasable using the best available treatment technology.
AL: Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Units Description:
ND: Not Detected; NR: Not Reported; MNR: Monitoring not required, but recommended; NA: Not applicable.
ppm: parts per million, or (mg/L) milligrams per liter ; ppb: parts per billion, or (ug/L) micrograms per liter ; ppt: parts per trillion, or nanograms per liter.

*(1) Total Coliform. Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially-harmful, bacteria may be present.
 (2) Fecal coliform/E.Coli. Fecal coliforms 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 short-term effects, such as diarrhea, cramps, nausea, headaches, or other symptons. They may pose a special health risk for infants, young children, and people with severely compromised immune systems.
Lead: Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home's plumbing. If you are concerned about elevated lead levels in your home's water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline (800-426-4791).
Why are there contaminants in my drinking water? 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 water poses a health risk. More information about contaminants and potential health effects ca be obtained by calling the Environmental Protection Agency's Safe DrinkingWater Hotline (800-426-4791).
Do I need to take special precautions? Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised 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/Centers for Disease Control (CDC) guidlines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are availble from the Safe Water Drinking Hotline (800-426-4791).
