Definitions and Abbreviations The following tables contain scientific terms and measures, some of which may require explanation.

Action Level:

Action Level Goal (ALG):

Avg:

Level 1 Assessment:

The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

The level of a contaminant in drinking water below which there ls no known or expected risk to health. AlGs allow for a margin of safety.

Regulatory compliance with some MCls are based on running annual average of monthlysam pies.

A Level 1 assessment is a study of the water system to identify potential problems and determine {if possible) why total coliform bacteria have been found in our water svstem.

Level 2 Assessment: A level 2 assessment is a very detailed study of the water system to identify potential problems and determine (if possible) why an E.coli MCL violation has occurred and/or whv total coliform bacteria have been found in our water svstem on muttiole occasions.

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 Leve! 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 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.

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.

MFL million fibers per liter (a measure of asbestos)

mrem: millirems per year (a measure of radiation absorbed by the body)

na: not applicable.

NTU nephelometric turbidity units (a measure of turbidity)

pCi/l picocuries per liter (a measure of radioactivity)

ppb: micrograms per liter or parts per billion- or one ounce in 7,350,000 gallons of water.

ppm: milligrams per liter or parts per million - or one ounce in 7,350 gallons of water.

ppq parts per quadrillion, or picograms per liter {pg/l)

ppt parts per trillion, or nanograms per liter (ng/l)

Treatment Technique or TT: A required process intended to reduce the level of a contaminant in drinking water.

Information about your Drinking Water 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 the lano 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. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessar'ily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPAs Safe Drinking Water Hotline at (800) 426-4791. Contaminants that may be present in source water include: · Microbial contaminants} such as viruses and bacteria, which may come from sewage treatment plants, septic systems1 agricultural livestock operations, and wildlife. - Inorganic contaminants, such as salts and metals, which can be naturally-occurring or resu It from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production1 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 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 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. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Contaminants may be found in drinking water that may cause taste, color, or odor problems. These types of problems are not necessarily causes for health concerns. For more information on taste, odor1 or color of drinking water, please contact the system1s business office. You may be more vulnerable than the general population to certain microbial contaminants, such as Cryptosporidium, in drinking water. Infants, some elderly, or immunocompromised persons such as those undergoing chemotherapy for cancer; persons who have undergone organ transplants; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders, can be particularly at risk from infections. You should seek advice about drinking water from your physician or health care providers. Additional guidelines on appropriate means to lessen the risk of infection by Cryptosporidium are available from the Safe Drinking Water Hotline (800-426-4791) 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. We are responsible for providing high quality drinking water, but we 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 or at http://www.epa.gov/safewater/lead . . CENTRAL TEXAS COLLEGE KILLEEN purchases water from CITY OF COPPERAS COVE. CITY OF COPPERAS COVE provides purchase surface water from [BELTON LAKE] located in [BELL COUNTY].

Turbidity Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease causing organisms. These organisms include bacteria,

virus, and parasites that can cause symptoms such as nausea, cramps, and diarrhea and associated headaches.

Total Organic Carbon ( TOC) Total Organic Carbon (TOC) is an indirect measure of organic molecules present in water and measured as carbon. Organic molecules are introduced into the water from the source water, from purification, and from distribution

materials. TOC is measured for both process control purposes and to satisfy regulatory requirements.

Total Coliform

Total coliform bacteria are used as indicators of microbial contamination of drinking water because testing for them is easy. While not disease-causing organisms themselves, they are often found in association with other microbes that are capable of causing disease. Coliform bacteria are harder than many disease-causing organisms, therefore, their absence from water fs a good indication that the water is micro biologically safe for human consumption. The City of Copperas Cove collected 480 total coliform samples for 2017. There was two positive coliform bacteria and one E. coli samples detected in 2017.

TCEQ Texas Commission on Environmental Quality

Lead Copper Rule for Community Water Systems Form 20681a

Lead Exceedance Public Education Requirements FOR COMMUNITIES

[CENTRAL TEXAS COLLEGE KILLEEN} found elevated levels of lead in drinking water in the home(s) at the community during JULY 2016 of Lead and Copper sampling 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.

This notice is being sent to you by Central Texas College.Texas State Water System ID# 0140174 on 21 DAY of November 2016.

The Texas Commission on Environmental Quality (TCEQ) and Central Texas College are concerned about lead in your drinking water. Although most sinks had low levels of lead in the drinking water, some had high lead levels above the Environmental Protection Agency (EPA) action level of 15 parts per billion (ppb), or 0.015 milligrams of lead per liter of water (mg/L).

Please note, this is not a violation under federal or state law, it does however, prompt Central Texas College to have post Lead Public Education and if found to have a high level reading in subsequent sampling, a program in place to minimize lead in your drinking water by the end of December 2015. This program may include adding corrosion control treatment, source water treatment, and if necessary replacing lead service lines.

If you have any questions about how we are carrying out the requirements of the lead regulation, please give us a call at (254) 526-1585. This document explains the simple steps you can take to protect you and your family by reducing your exposure to lead in drinking water while in the Central Texas College Married Student Housing building (s).

TCEQ 2068la (Rev. 01-11-2015) Page 1 ofS

Health Effects of Lead

Lead can cause serious health problems if too much enters your body from drinking water or other sources. ft 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. Drinking water is one possible source of lead exposure. 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). Lead is found in some toys, some playground equipment, and some children's metal jewelry.

Lead in drinking water, although rarely the sole cause of lead poisoning can significantly increase a person's total lead exposure, particularly the exposure of infants who drink baby formulas and concentrated juices that are mixed with water. The Environmental Protection Agency (EPA) estimates that drinking water can make up 20 percent or more of a person's total exposure to lead. Lead is unusual among drinking water contaminants in that it seldom occurs naturally in water supplies like rivers and lakes. Lead enters drinking water primarily as a result of the corrosion, or the wearing away of materials containing lead in the water distribution system and household plumbing. These materials include lead-based solder used to join copper pipe, brass and chrome plated brass faucets, and in some cases, pipes made of lead that connect your house to the water main (service lines). Jn 1986, Congress banned the use of lead solder containing greater than 0.2% lead, and in 2011 restricted the lead content of faucets, pipes and other plumbing materials to 0.25%.

When water stands in lead pipes or plumbing systems containing lead for several hours or more, the lead may dissolve into your drinking water. This means the first water drawn from the tap in the morning, or later in the afternoon after returning from work or school, can contain fairly high levels of lead.

Steps You Can Take to Reduce Exposure to Lead in Drinking Water

1. Run water to flush out lead. Run water for 15 - 30 seconds to flush lead from interior plumbing or until it becomes cold or reaches a steady temperature before using it for drinking or cooking, if it hasn't been used for several hours.

2. Use cold water for cooking and preparing baby formula. Do not cook with or drink water from the hot water tap; lead dissolves more easily into hot water. Don't use water from the hot water tap to make baby formula.

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

4. Look for alternative sources or treatment of water. You may wantto consider purchasing bottled water or a water filter. Read the package to be sure the filter is approved to reduce lead. Be sure to maintain and replace a filter device in accordance with the manufacturer's instructions to protect water quality. Contact NSF International at 800-NSF-8010 or www.nsf.org for information on performance standards for water filters.

5. Get your child's blood 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.

What Happened and What is Being Done Routine sampling was completed in July 2016 Four out often sample exceeded the action level from Married Student Housing sink. Additional sampling will be performed in January 2017 of additional sampling.

The areas of concern were resampled and did not exceed the lead or copper contaminate levels.

The samples were taken in areas where the buildings were not in use and had not been occupied in over a year. Due to the location of these sample sites and the resampling of these areas that came back below the MCL (maximum contaminant level) there is no level of concern to the college. We are required by TCEQ to send out this letter and make available the educational brochure to our employees that are in the areas where the test was tsaken.

We will continue to work with TCEQ to provide the quality of domestic water that our public water system is accustom to providing to our students, faculty, and staff.
