2015 Water Quality Report
The mission of the Roanoke Rapids Sanitary District is to affordably provide the highest quality water services; then safely collect wastewater and return clean water to the environ- ment while promoting public trust and partnerships to the benefit of our associates and the satisfaction of our customers.
The Roanoke Rapids Sanitary District, a municipal corporation, was created by the North Carolina State Board of Health on April 21, 1931; under and by virtue of an act of the General Assembly, ratified on March 4, 1927, providing for the creation, government and operation of Sanitary Districts. The Roanoke Rapids Sanitary District is governed by a 3-member board; which is elected, at large, to two year terms. Should you have any questions concerning this Report, please call our Administrative Office at (252) 537-9137.
The Roanoke Rapids Sanitary District welcomes public participation in decisions concerning your water, wastewater, or distribution/collection systems. The District Board holds a public meeting the second Thursday of every month beginning at 5:30 P.M. at the Administrative Office, 1000 Jackson Street, Roanoke Rapids

The Roanoke Rapids Sanitary District’s number one priority is to provide all our cus- tomers with a safe and reliable supply of water that can be used with confidence. Every day, our employees are working to ensure that the water you drink meets all regulatory requirements and your expectations for safety, reliability, and quality.
To do this we conduct over 35,000 tests yearly on the water you drink. These tests start in the raw (untreated) water from the Roanoke Rapids Lake. (We also have an intake in the Roanoke River to draw water from in an emergency) We also run hun- dreds of tests on the water at different phases of the treatment process. The final tests are done on water from randomly selected homes and businesses. All of these test results are reported in accordance with the Water Quality Standards established by the United States Environmental Protection Agency (EPA) and the North Carolina Department of Environmental Health. We are proud to report that the water provid- ed by the Roanoke Rapids Sanitary District exceeds all established water quality stand- ards.
This 2015 WATER QUALITY REPORT is a summary of many of these tests and expla- nations of terms used in water quality reporting. If you have any further questions, please contact the WATER TREATMENT PLANT between 8AM and 4PM at (252) 537-3319.
Lead & Copper Rule Testing
The 1994 Federal Lead & Copper Rule mandates a household testing program for these substances. According to the rule, 90% of the samples from high risk homes must have levels less than 0.015 mg/L of lead and 1.3 mg/L of copper. In 2014, our last required testing, Lead levels in the District averaged .005 mg/L and copper levels averaged .173 mg/L, well below the Federal levels. Our next lead and copper testing will be conducted in August of 2017. 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 Roanoke Rapids Sanitary District 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 avail- able from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.

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 con- taminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer un- dergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be partic- ularly at risk from 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)
Maximum Residual Disinfection Level Goal – The “Level” (MRDLG) of a drinking water disin- fectant 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 contami- nants
Maximum Residual Disinfection Level– The “Highest Level” (MRDL) of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Maximum Contaminant Level (MCL)– An en- forceable level of a contaminant as close to the goal as is practical to achieve in light of available treat- ment technology and cost/benefit considerations.
Maximum Contaminant Level Goal (MCLG)– A level of a contaminant, not necessarily achievable, safely below the level of human health concerns.
Action Level (AL)– The level of a contaminant at which a water treatment plant must take some type of action to reduce or contain the contaminant
Treatment Technique (TT)– A required process intended to reduce the level of a contaminant in drinking water.
Parts Per Million (PPM)– Equivalent to milli- grams per liter(mg/L). One part per million is com- parable to one minute in two years.
Parts Per Billion (PPB)– Equivalent to mi- crograms per liter. One part per billion is compara- ble to one minute in two thousand years.
Nephelometric Turbidity Units (NTU)– Turbidi- ty is a measure of cloudiness in water.
Turbidity is usually thought of as cloudiness of the water, and is caused by suspended matter. Organic and inorganic material, silt, algae or other tiny organisms can contribute to the turbidi- ty of the water.
The degree of turbidity is measured at the Wa- ter Treatment Plant laboratory by shining a beam of light through water and measuring the angle at which the light is scattered by suspended matter. The reading gives the turbidity of the water meas- ured in Nephelometric Turbidity Units (NTU’S).
Regulations passed in 1989 recognize reducing turbidity as one way to measure the removal or inactivation of certain targeted microorganisms. Currently, Giardia is one of those microorganisms and future regulations may include Cryptosporidi- um.
The EPA has established a Maximum Contami- nant Level (MCL) for treated water turbidity of 0.3 NTU. The rule requires us to meet this standard 95% of the time during the month. In 2015, we met the standard 99.99% of the time with our highest reading at 0.32 NTU. For the year, we averaged 0.043 NTU
