Important Information About Your Drinking Water

We’re pleased to present to you this year’s Annual Water Quality Report. This report is designed to inform you about the quality water and 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 source is groundwater. Our water source is groundwater, drawn from the Columbia/Pocomoke Aquifer.

Dear Customer:
The Division of Public Health in conjunction with the Department of Natural Resources and Environmental Control has conducted a source water assessment. If you are interested in reviewing this assessment, which provides information such as potential sources of contamination, it is available on the Town’s website (www.oceanviewde.cm), at the Town Hall located at 32 West Avenue, and the second floor of the Wallace A. Melson Administration and Public Safety Building located at 201 Central Avenue and can be received via email by contacting the Town Administrative Official at admintov@verizon.net. The assessment will not be mailed to water system customers.

Please contact Town Administrative Official Charles McMullen at 302-539-1208 if you have any questions about this report or your water utility. We want our valued customers to be informed about their water utility.

Public Health, Office of Drinking Water routinely monitors for constituents in your drinking water according to Federal and State laws. This table shows the results of our monitoring for the period of January 1st to December 31st, 2008. As water travels over the land or underground, it can pick up substances or contaminants such as microbes, inorganic and organic chemicals, and radioactive substances. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It’s important to remember that the presence of these constituents does not necessarily pose a health risk.

THE WATER TREATMENT PROCESS
To provide you with quality drinking water, reliable treatment methods are used to eliminate or minimize the effects of contaminants that may be present in source waters. Water quality is monitored at each wellfield and throughout the distribution system to determine that state and federal primary water quality standards are met.
Groundwater from wells first passes through layers of soil, sand and gravel, which act as a natural filter. Groundwater comes from an underground source of water known as an aquifer. Those groundwater supplies are disinfected with chlorine to destroy bacteria that may be present and protect against microbial contaminants before being pumped into the distribution system. The level of this additive is monitored daily to ensure the proper dosage is being added. In some cases, pH correction and filtration are utilized.
Samples of treated and untreated water are taken regularly to ensure that the required level of drinking water quality is maintained and that samples comply with state and federal standards for quality and safety.

A Word of Caution
Town of Ocean View’s treatment system is designed and operated to produce water that is in compliance with all state and federal drinking water standards. Many substances and microscopic organisms found in water may be a concern if they occur at high concentrations. For some contaminants, Maximum Contaminant Levels (MCL) have not been set because the EPA has not determined at what level they pose a public health risk. This is often because a reliable detection method is unavailable and/or because the contaminant is rarely found in treated water.
Some naturally occurring organisms commonly found in the natural water supplies may not be eliminated during the treatment process. This means that even a well-run system may contain low levels of microscopic organisms. The levels, however, are normally of little concern to healthy individuals. It should be noted, however, that under certain circumstances, these organisms might amplify to serious levels within a customer’s own water supply system.
All customers, including residential, commercial and industrial customers, and other large facilities such as schools, hospitals and hotels/motels, should follow appropriate procedures for maintaining their own internal plumbing systems and appliances. If you have any concerns about these matters, please call the EPA Safe Drinking Water Hotline at (800)426.4791.

WHY THERE MAY BE CONTAMINANTS IN THE COUNTRY’S WATER SUPPLY
1Sources of drinking water in the United States (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over land or through the ground, it dissolves naturally occurring minerals and organics and can pick up substances resulting from the presence of animal or human activity. Contaminants that may be present in source waters include:

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, livestock and wildlife.

Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from storm water runoff, wastewater discharges, or farming.

Pesticides and herbicides, which may come from a variety of sources such as agriculture, storm water runoff, and residential uses.

Organic contaminants, including natural, synthetic and volatile organic chemicals, which are by-products of nature and industrial processes and petroleum production, and can also come from gas stations, storm water runoff and septic systems.

Radioactive contaminants, which can be naturally occurring.

All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. Fortunately, in Delaware, most of these contaminants are not an issue. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline at (800)426-4791.

In order to ensure that tap water is safe to drink, the EPA and the State Division of Public Health (DPH) prescribe 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. DPH also provides monitoring schedules and establishes sampling requirements for water utilities in order to maintain compliance with the Safe Drinking Water Act monitoring requirements.

What the Numbers Mean To You: The table shows the results of our monitoring during 2008. The EPA requires monitoring of numerous drinking water contaminants. Those listed are the only contaminants detected. The State requires water systems to monitor for certain contaminants less than once a year because the concentration of these contaminants is not expected to vary significantly from year to year.

Definitions and Abbreviations used below: Primary Standards: Standards which relate to public health. MCLG: Maximum Contaminant Level Goal. 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. MCL: Maximum Contaminant Level. 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. PPB: Parts per Billion. PPM: Parts per Million. PPT: Parts per Trillion. MFL: Million Fibers per Liter. N/A: Not Applicable. ND: None Detectable at testing limit. NDA: No Data Available. CNR: Currently Not Regulated. pCi/l: Picocuries per Liter. A measure of radioactivity in water.
NTU: (Nephelometric Turbidity Unit) used to measure cloudiness in drinking water. Std: Standard Units. RUL: Recommended Upper Limit. AL: Action Level. The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. >: Less than.

For Your Safety - A Message for People with Compromised Immune Systems
Certain individuals may be more vulnerable to contaminants in drinking water than the general population and have special needs regarding water quality. Immuno-compromised individuals 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 individuals 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 microbial contaminants are available from the EPA’s Safe Drinking Water Hotline at (800)426-4791.

Special Considerations Regarding Children, Pregnant Women, Nursing Mothers, and Others
Children may receive a slightly higher amount of contaminant present in the water than do adults, on a body weight basis, because they may drink a greater amount of water per pound of body weight than do adults. For this reason, reproductive or developmental effects are used for calculating a drinking water standard if these effects occur at lower levels than other health effects of concern. If there is insufficient toxicity information for a chemical (for example, lack of data on reproductive or developmental effects), an extra uncertainty factor may be incorporated into the calculation of the drinking water standard, thus making the standard more stringent, to account for additional uncertainties regarding these effects. In the cases of lead and nitrate, effects on infants and children are the health endpoints upon which the standards are based.
