	City of Rayne Water Department
	Public Water Supply ID: LA1001007   
	          We are pleased to present to you the Annual Water Quality Report for the year 2020.  This report is designed to inform you about the quality of your water and the services we deliver to you every day.  Our constant goal is to provide you with a safe and dependable supply of drinking water.  We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources.  We are committed to ensuring the 
quality of your water.  Our water sources are listed below:
	Source Name                 Source Location               Source Type	         Source ID Number
	WELL #7                                Chicot Aquifer                           Groundwater	               1001007-003
                    WELL #8                                Chicot Aquifer                           Groundwater	               1001007-004
                    WELL #9                                Chicot Aquifer                           Groundwater                         1001007-005
   The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include:
     Microbial Contaminants – such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
     Inorganic Contaminants - such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff, industrial, or domestic wastewater discharges, oil and gas production, mining, or farming.
     Pesticides and Herbicides – which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
     Organic Chemical Contaminants – including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
     Radioactive Contaminants – which can be naturally-occurring or be the result of oil and gas production and mining activities.
      A Source Water Assessment Plan (SWAP) is now available from our office.  This plan is an 
assessment of a delineated area around our listed sources through which contaminants, if 
present, could migrate and reach our source water.  It also includes an inventory of potential 
sources of contamination within the delineated area, and a determination of the water supply's 
susceptibility to contamination by the identified potential sources. According to the Source Water Assessment Plan, our water system had a susceptibility rating of “Medium”.  If you would like to review the Source Water Protection Plan, please feel free to contact our office at 337-334-6631. 
	         
          In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health. We are pleased to report that our drinking water is safe and meets Federal and State requirements. We want our valued customers to be informed about their water utility.  If you have any questions about this report or simply want to learn more about your drinking water, please contact Water & Waste Superintendent Mike Judice at 337-334-6631. 
  If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The City of Rayne Water System is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline (1-800-426-4791) or at http://www.epa.gov/safewater/lead.
 	          The Louisiana Department of Health and Hospitals/Office of Public Health routinely 
	monitors for constituents in your drinking water according to Federal and State laws.  The 
	tables that follow show the results of our monitoring during the period of January 1st to 
	December 31st, 2020.  All drinking water, including bottled drinking 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.

In the tables below, you will find many terms and abbreviations you might not be familiar with.  
To help you better understand these terms, the following definitions are provided:
AL - (Action Level) – the concentration of a contaminant that, if exceeded, triggers treatment or other requirements that a water system must follow.
ppm - (parts per million) or mg/L - (milligrams per liter) – one part per million corresponds to one minute in two years or a single penny in $10,000.
ppb - (parts per billion) or ug/L - (micrograms per liter) – one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
pCi/L - (picocuries per liter) – picocuries per liter is a measure of the radioactivity in water.
MCL - (Maximum Contaminant Level) – the “Maximum Allowed” MCL is the highest level of a 
contaminant that is allowed in drinking water.  MCL’s are set as close to the MCLG’s as feasible using 
the best available treatment technology.
MCLG - (Maximum Contaminant Level Goal) – the “Goal” is the level of a contaminant in drinking water 
below which there is no known or expected risk to human health.  MCLG’s allow for a margin of safety.

MRDL (Maximum Residual Disinfectant Level) – 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.

MRDLG (Maximum Residual Disinfectant Level Goal) – 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 contamination.

Level 1 Assessment – A study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system.

Level 2 Assessment – A very detailed study of the water system to identify potential problems and determine (if possible) why E.coli MCL violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions. 

SMCL – (Secondary Maximum Contaminant Level) Secondary standards regulate contaminant levels based on aesthetics such as color and odor which do not pose a risk to health. These secondary maximum contaminant levels (SMCLs) are guidelines, not enforceable limits. They identify acceptable concentrations of contaminants which cause unpleasant tastes, odors, or colors in the water. SMCLs are for contaminants that will not cause adverse health effects.

Treatment Technique (TT) – an enforceable procedure or level of technological performance which public water systems must follow to ensure control of a contaminant.

During the period covered by this report we had the below noted violations of drinking water regulations.

+++++Environmental Protection Agency Required Health Effects Language++++++
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 for infections.  
These people should seek advice about drinking water from their health care providers.  
EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium 
and other microbiological contaminants are available from the Safe Drinking Water Hotline 
(800-426-4791).
