2016 Annual Drinking Water

  Quality Report for the

Town of Smithfield

 

This Annual Drinking Water Quality Report for calendar year 2016 is designed to inform you about your drinking water quality.  Our goal is to provide you with a safe and dependable supply of drinking water, and we want you to understand the efforts we make to protect your water supply.  The quality of your drinking water must meet state and federal requirements administered by the Virginia Department of Health (VDH).

If you have any questions about this report, want information about any aspect of your drinking water or want to know how to participate in decisions that may affect the quality of your drinking water, please contact Mr. Jack Reed, Plant Manager of the Public Works Department, at 757-365-4258.

The times and location of regularly scheduled Town Council meetings are the 1st Tuesday of each month at 7:30 p.m. at The Smithfield Center located at 220 North Church Street, Smithfield, Virginia. 

This annual “Consumer Confidence Report”, required by the Safe Drinking Water Act (SDWA), explains where your water comes from, results from lab analyses, and other things you should know about your drinking water.  We are committed to ensuring the quality of your water.  Our constant goal is to provide you and your family with a safe and dependable supply of drinking water.

Mr. Jack Reed, Mr. Dale Wall, and Mr. Tim Perkins serve as the Licensed Waterworks Operators for the Town of Smithfield who operate the reverse osmosis water treatment plant. Mr. Jessie Snead serves as the Public Works Superintendent.

 

General Information

As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and can pick up substances resulting from the presence of animals or from human activity.  Substances (referred to as contaminants) in source water may come from septic systems, discharges from domestic or industrial wastewater treatment facilities, agricultural and farming activities, urban storm water runoff, residential uses, and many other types of activities.  Water from surface sources is treated to make it drinkable while groundwater may or may not have any treatment. 

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. 

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 storm water 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 storm water runoff, and residential uses.
  • Organic Chemical Ccontaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems.
  • Radioactive Contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.

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. The Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

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.  More information 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.  Immunocompromised 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/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).

 

Source(s) and Treatment of Your Drinking Water

The source of your drinking water is groundwater from drilled wells that are pumped into the Reverse Osmosis Plant where it is treated and sampled and sent to distribution.  The plant was put online in September 2011. The Water Treatment Plant employs reverse osmosis to remove naturally occurring fluoride from the groundwater.  The facility produces treated water with a fluoride concentration averaging 1.1 ppm (parts per million).  The treated water is dosed with sodium hypochlorite and lime for taste and odor control.

VDH conducted a Source Water Assessment of the Town of Smithfield Waterworks in 2002.  The wells were determined to be of high susceptibility to contamination using the criteria developed by the state in its approved Source Water Assessment Program. The assessment report consists of maps showing the Source Water Assessment area, an inventory of known Land Use Activities and Potential Conduits to Groundwater, utilized at Land Use Activity sites in Zone 1 and documentation of any known contamination within the last five years, Susceptibility Explanation Chart, and Definitions of Key Terms.  The report is available by contacting your waterworks system owner/operator at the phone number or address included in this report.

 

Definitions

Contaminants in your drinking water are routinely monitored according to Federal and State regulations.  The table on page 6 shows the results of our monitoring for calendar year 2015. In the table and elsewhere in this report you will find many terms and abbreviations you might not be familiar with. The following definitions are provided to help you better understand these terms:
 

  • Non-detects (ND) – lab analysis indicates that the contaminant is not present.
  • Parts per million (ppm) or Milligrams per liter (mg/l) – one part per million corresponds to one minute in two years or a single penny in $10,000.
  • Parts per billion (ppb) or Micrograms per liter  one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
  • Picocuries per liter (pCi/L) – picocuries per liter is a measure of the radioactivity in water. 
  • Nephelometric Turbidity Unit (NTU) – nephelometric turbidity unit is a measure of the clarity, or cloudiness, of water.  Turbidity in excess of 5 NTU is just noticeable to the average person. Turbidity is monitored because it is a good indicator of the effectiveness of our filtration system.
  • Action Level – the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
  • Treatment Technique (TT)  a required process intended to reduce the level of a contaminant in drinking water.
  • Maximum Contaminant Level, or MCL  the highest level of a contaminant that is allowed in drinking water.  MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
  • Maximum contaminant Level Goal, or MCLG – the level of a contaminant in drinking water below which there is no known or expected risk to health.  MCLGs allow for a margin of safety.
  • Maximum residual disinfectant level goal or MRDLG – 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 contaminants.
  • Maximum residual disinfectant level or MRDL – 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.

 

We constantly monitor for various contaminants in the water supply to meet all regulatory requirements.  The table lists only those contaminants that had some level of detection.  Many other contaminants have been analyzed but were not present or were below the detection limits of the lab equipment.

Most of the results in the table are from testing done in 2015. However, the state allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently.

In developing standards, the EPA assumes that the average adult drinks 2 liters of water each day throughout a 70 year life span. MCL’s are set at very stringent levels by the U.S. Environmental Protection Agency.  In developing the standards EPA generally sets MCLs at levels that will result in no adverse health effects for some contaminants or a one-in-ten-thousand to one-in-a-million chance of having the described health effect for other contaminants.

 

Lead and Copper

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 Town of Smithfield 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 15 to 30 seconds or until it becomes cold or reaches a steady temperature 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 or at www.epa.gov/safewater/lead.
