Lead and Copper Sampling Procedures

Sample will be taken Tuesday morning August 21, 2007 The night before:

1. The sample will be collected from the cold water tap in the kitchen. Remove, clean and replace the faucet aerator the night before the sample is to be taken. Please note that this tap must not be connected with any type of water purification device.

2. Run the water for several minutes prior to going to bed. 3. Do not use any water in the house for six to eight hours before you take the

sample. This includes all plumbing fixtures located both inside and outside of your home, toilets, taps, dishwashers, and other water-using devices that are connected to or able to be connected to household plumbing

4. Should any water be used or flushed within the 6-8 hours of collection the sample, do not collect the sample and contact our Water System representative at the number below. The morning sample is taken:

1. Do not remove the lid from the bottle until you are ready to collect the sample. 2. Do not rinse the sample bottle as it contains a preservative. 3. Unscrew the lid from the bottle. 4. Before turning the cold water on in your kitchen sink, position the opened bottle

under the faucet. With the sample bottle held directly under the tap, slowly open the cold water (only) tap to allow all the running water to enter the sample bottle. Be sure the mouth of the bottle completely encloses the tap head but do not allow the tap head to make contact with the water in the bottle.

5. Fill the sample bottle to approximately ½ inch from the top. Use care during the filling procedure to be sure that no water is allowed to go down the drain, all water should be collected in the sample bottle.

6. Turn off the water, bring the bottle away from the faucet and immediately screw the lid back on, be sure it is tight and secure.

7. After the sample is collected, normal household water usage may resume. 8. Fill out and sign the information below:

Sample Date _________________________________ Sample Time _________________________________ Hours motionless in system______________________ Collector’s signature____________________________

Check again to make sure the bottle’s lid is on securely. Place the bottle in the sampling package along with this sheet. Place the package at the front entrance door. We will pick this up between 8:00 and 9:00 A.M. If you have any questions, please contact I*&)& at 555-5555 ext. 239 or (&*)&)*(&*() at 555-5555 ext. 238.

Flush, then let water sit for at least 6 hours

EPA does not recommend removing and

cleaning aerators

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER

_____________________________[Insert name of your water system] appreciates your participation in the lead tap monitoring program. This notice is to inform you of the lead tap monitoring results for the drinking water sample collected at the location identified below:

Street Address_____________________________________ City _____________________

Tap Location______________________________________

Sample Collected Lab Results Received Lead Test Results/ Units Action Level/ Units MCLG Date: _________ Date: _________ ____________ mg/L 0.015 mg/L 0 mg/L The action level is the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. The MCLG (Maximum Contaminant Level Goal) is 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. What are the Health Effects of Lead? Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones and it can be released later in life. During pregnancy, the child receives lead from the mother’s bones, which may affect brain development. Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure. (40 CFR 141 Subpart Q, Appendix B)

Steps you can take to reduce your exposure to lead in your drinking water: • Run your water to flush out lead. If water hasn’t been used for several hours, run

water for 15 to 30 seconds or until it becomes cold or reaches a steady temperature before using if for drinking or cooking.

• Use cold water for cooking and preparing baby formula. • Do not boil water to remove lead. • Look for alternative sources or treatment of water. • Test your water for lead. • Get your child tested. • Identify if your plumbing fixtures contain lead.

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER SAMPLE

North Carolina’s Rules Governing Public Water Systems (15A NCAC 18C) require that a public water system sample for certain contaminants that may occur in the drinking water distribution system. For many contaminants, multiple water samples are necessary to determine a system’s compliance with the water quality standards. Although several sample results may exceed the allowable limits, the system may be in compliance based on multiple sample results and will not be required to perform system-wide public notification or take corrective action. However, the consumers of the drinking water at an individual location where the allowable limits are exceeded are still susceptible to adverse health effects. The purpose of this notice is to inform you of the analytical results for the drinking water sample collected at the location identified below. Since the allowable limit was exceeded at this location, the potential health effects are also included so you can take any precautionary measures you feel are necessary to further protect your health.

IMPORTANT INFORMATION ABOUT LEAD IN YOUR DRINKING WATER [Insert name of water system] found elevated levels of lead in drinking water in some homes/buildings. Lead can cause serious health problems, especially for pregnant women and young children. Please read this information closely to see what you can do to reduce lead in your drinking water. Health Effects of Lead: Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother’s bones, which may affect brain development. Sources of Lead: Lead is a common metal found in the environment. The main sources of lead exposure are lead-based paint and lead-contaminated dust or soil, and some plumbing materials. In addition, lead can be found in certain types of pottery, pewter, brass fixtures, food, and cosmetics. Other sources include exposure in the work place and exposure from certain hobbies (lead can be carried on clothing or shoes). Drinking water is also a possible source of lead exposure. Most sources of drinking water have no lead or very low levels of lead. Most lead gets into drinking water after the water leaves the local well or treatment plant and comes into contact with plumbing materials containing lead. These include lead pipes, and lead solder (commonly used until 1986), as well as faucets, valves, and other components made of brass. Brass faucets, fittings, and valves, including those advertised as “lead-free,” may contribute lead to drinking water. EPA estimates that 10 to 20 percent of a person’s potential exposure to lead may come from drinking water. Infants who consume mostly formula mixed with lead-containing water can receive 40 to 60 percent of their exposure to lead from drinking water. Steps You Can Take to Reduce Your Exposure to Lead in Your Drinking Water:

Steps Reason

Run your water to flush out lead.

If water hasn’t been used for several hours, run water for at least 15-30 seconds or until it becomes cold or reaches a steady temperature before using it for drinking or cooking. Note: You may want to capture the initial running water for uses other than drinking or cooking, such as for watering the plants.

Use cold water for cooking and preparing baby formula. Lead dissolves more easily into hot water.

Do not boil water to remove lead. Boiling water will not reduce lead.

Look for alternative sources or treatment of water.

You may want to consider purchasing bottled water or a water filter. Be sure the filter is approved to reduce lead or contact NSF International at 1-800-NSF-8010 or www.nsf.org for performance standards for water filters.

Test your water for lead. Call us at [water system’s phone #] to find out how to get your water tested for lead, if any fees apply, and the location of labs that perform private testing.

Get your child tested. Contact your local health department or healthcare provider to find out how you can get your child tested for lead if you are concerned about exposure.

Identify if your plumbing fixtures contain lead (replace, if necessary).

Brass faucets, fittings, and valves, including those advertised as “lead-free,” may contribute lead to drinking water. The law currently allows end-use brass fixtures, such as faucets, with up to 8% lead to be labeled as “lead-free.” Visit the NSF Web site at www.nsf.org to learn more about lead-containing plumbing fixtures.

What happened? What is being done? [Insert information about how and when the exceedance was discovered in your community and provide information on the source(s) of lead, in the drinking water, if known. Explain why there are elevated levels of lead in your system’s drinking water (if known) and describe what your system is doing to reduce the lead levels in homes/buildings in your community.]

For More Information call us at [insert system’s phone #] [(If applicable), or visit our Web site at [insert Web site here]. For more information on reducing lead exposure around your home/building and the health effects of lead, visit EPA’s Web site at http://www.epa.gov/lead or contact your health care provider.
