Initial S ampling - Organic Chemicals. \n(a) Each community and nontransient -noncommunity water system shall collect four \nquarterly samples during the year designated by the State Board of each compliance period beginning with the compliance period starting January 1, 1993, from each water source at a site prior to any treatment and test for all applicable organic chemicals listed in table 64444- A. The State Board will designate the year based on historical monitoring \nfrequency and laboratory capacity.  For surface sources, the samples shall be taken at each water intake. For groundwater sources, the samples shall be taken at each well head. Where multiple intakes or wells draw from the same water supply, the State Board will consider sampling of representative sources as a means of complying with \nthis section. Selection of representative sources shall be based on evidence which includes a hydrogeological survey and sampling results. Wells shall be allowed to flow for a minimum of 15 minutes before sampling to insure that the samples reflect the water quality of the source. In place of water source samples, a supplier may collect samples at sites located at the entry points to the distribution system. The samples shall be representative of each source after treatment. The system shall collect each sample at the same sampling site, unless a change is approved by the State Board. \n (b) For any organic chemical added to table 64444- A, the water system shall initiate \nthe quarterly monitoring for that chemical in January of the calendar year after the effective date of the MCL.  \n (c) A water system may request approval from the State Board to composite \nsamples from up to five sampling sites, provided that the number of the sites to be composited is less than the ratio of the MCL to the DLR in \u00a764445.1. Approval will be based on a review of three years of historical data, well construction and aquifer information for groundwater, and intake location, similarity of sources, and watershed characteristics for surface water. Compositing shall be done in the laboratory and analyses shall be conducted within 14 days of sample collection.  \n(1) Systems serving more than 3,300 persons shall composite only from \nsampling sites within a single system. Systems serving 3,300 persons or less may composite among different systems up to the 5- sample limit.  \n(2) If any organic chemical is detected in the composite sample, a follow -up \nsample shall be analyzed within 14 days from each sampling site included in the composite for the contaminants which were detected. The water supplier shall report the results to the State Board within 14 days of the follow -up sample collection. If available, \nduplicates of the original sample taken from each sampling site used in the composite may be used instead of resampling.  \n \n(d) A water system may apply to the State Board for a monitoring waiver for one or \nmore of the organic chemicals on table 64444- A in accordance with the following:", "start_char_idx": 0, "end_char_idx": 3028, "text_template": "{metadata_str}\n\n{content}", "metadata_template": "{key}: {value}", "metadata_seperator": "\n"}, "__type__": "1"}, "604c999b-3cb7-4a90-bb4d-ddb6cb2e192d": {"__data__": {"id_": "604c999b-3cb7-4a90-bb4d-ddb6cb2e192d", "embedding": null, "metadata": {"page_label": "130", "file_name": "CADWReg.pdf"}, "excluded_embed_metadata_keys": [], "excluded_llm_metadata_keys": [], "relationships": {"1": {"node_id": "30500ee5-c198-4ca8-8b8e-21ac659ee1e9", "node_type": null, "metadata": {"page_label": "130", "file_name": "CADWReg.pdf"}, "hash": "a0211138ab9683a79381030b76b8e645c154b89c44223ca94325fd33c0ea2eca"}}, "hash": "00b62e2511adf6d54fc531fdbd234adaa07c03702403d1a6907a548071aa8f0d", "text": "(1) A source may be eligible for a waiver if it can be documented that the \nchemical has not been previously used, manufactured, transported, stored, or disposed \nof within the watershed or zone of influence and therefore, that the source can be designated nonvulnerable.  \n(2) If previous use of the chemical locally is unknown or the chemical is known to \nhave been used previously and the source cannot be designated nonvulnerable pursuant to Paragraph (d)(1), it may still be eligible for a waiver based on a review related to susceptibility to contamination.

The arsenic standard balances the current understanding of arsenic's possible health effects against the costs of removing arsenic from drinking water.  The U.S. Environmental Protection Agency continues to research the health effects of low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems. \u201d \n (b) A system that detects nitrate at levels above 5 mg/L (as nitrogen), but below the \nMCL, shall include the following in its Consumer Confidence Report: \u201cNitrate in drinking water at levels above 10  mg/L is a health risk for infants of less than six months of age. \nSuch nitrate levels in drinking water can interfere with the capacity of the infant's blood to carry oxygen, resulting in a serious illness; symptoms include shortness of breath and blueness of the skin. Nitrate levels above 10 mg/L may also affect the ability of the \nblood to carry oxygen in other individuals, such as pregnant women and those with certain specific enzyme deficiencies. If you are caring for an infant, or you are pregnant, you should ask advice from your health care provider. If a system cannot demonstrate to the State Board with at least five years of the most current monitoring data that its nitrate levels are stable, it shall also add the following language to the preceding statement on nitrate: \u201cNitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. \u201d \n (c) A system that detects lead above the action level in more than 5%, and up to and \nincluding 10%, of sites sampled, shall include the following in its Consumer Confidence Report: \u201cInfants and young children are typically more vulnerable to lead in dri nking \nwater than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home's plumbing.

If you have any questions about how we are carrying out the requirements of the lead regulation please give us a call at [insert water system's phone number].  This brochure explains the simple steps you can take to protect you and your family by reducing your exposure to lead in drinking water.  \n(B) HEALTH EFFECTS OF LEAD.  Lead is a common metal found \nthroughout the environment in lead- based paint, air, soil, household dust, food, certain \ntypes of pottery porcelain and pewter, and water.  Lead can pose a significant risk to your health if too much of it enters your body. Lead builds up in the body over many years and can cause damage to the brain, red blood cells and kidneys.  The greatest risk is to young children and pregnant women.  Amounts of lead that won't hurt adults can slow down normal mental and physical development of growing bodies.  In addition, a child at play often comes into contact with sources of lead contamination -- like dirt \nand dust -- that rarely affect an adult.  It is important to wash children's hands and toys \noften, and to try to make sure they only put food in their mouths.  \n(C) LEAD IN DRINKING WATER \n1. Lead in drinking water, although rarely the sole cause of lead poisoning,  \ncan 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 U.S. Environmental Protection Agency estimates that drinking water can make up 20 percent or more of a person's total exposure to lead.  \n2. Lead is unusual among drinking water contaminants in that it seldom \noccurs naturally in water supplies like rivers and lakes. Lead enters drinking water primarily as a result of the corrosion, or 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).  In 1986, Congress banned the use of lead solder containing greater than 0.2% lead, and restricted the lead content of faucets, pipes and other plumbing materials to 8.0%.  In California, a similar law prohibiting the use of both lead solder and lead pipe was enacted in 1985.  \n3. When water stands in lead pipes or plumbing systems containing lead \nfor 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.  \n(D) STEPS  YOU CAN TAKE IN THE HOME TO REDUCE EXPOSURE TO \nLEAD IN DRINKING WATER", "start_char_idx": 0, "end_char_idx": 3348, "text_template": "{metadata_str}\n\n{content}", "metadata_template": "{key}: {value}", "metadata_seperator": "\n"}, "__type__": "1"}, "aee378fb-99c9-4d82-aaf4-97d3597d303f": {"__data__": {"id_": "aee378fb-99c9-4d82-aaf4-97d3597d303f", "embedding": null, "metadata": {"page_label": "301", "file_name": "CADWReg.pdf"}, "excluded_embed_metadata_keys": [], "excluded_llm_metadata_keys": [], "relationships": {"1": {"node_id": "9b21d1ee-7f5d-44c7-a6bb-0fb3a28471bf", "node_type": null, "metadata": {"page_label": "301", "file_name": "CADWReg.pdf"}, "hash": "e0fc71dc6ecff04aa851aafdacbc453e86171379a5a0c64230df7366d37b6741"}}, "hash": "ad3d3effb2365f10c1e5b7ad307e0b22533bb74dc082e9e8d9df2bb67ca65393", "text": "1. Despite our best efforts mentioned earlier to control water corrosivity \nand remove lead from the water supply, lead levels in some homes or buildings can be \nhigh.  To find out whether you need to take action in your own home, have your drinking \nwater tested to determine if it contains excessive concentrations of lead.  Testing the water is essential because you cannot see, taste, or smell lead in drinking water.   Some \nlocal laboratories that can provide this service are listed at the end of this booklet.  For more information on having your water tested, please call [insert phone number of water system]. \n2. If a water test indicates that the drinking water drawn from a tap in your \nhome contains lead above 15 ppb, then you should take the following precautions:  \nA. Let the water run from the tap before using it for drinking or cooking \nany time the water in a faucet has gone unused for more than six hours.  The longer water resides in your home's plumbing the more lead it may contain.  Flushing the tap means running the cold water faucet until the water gets noticeably colder, usually about 15 to 30 seconds.  If your house has a lead service line to the water main, y ou \nmay have to flush the water for a longer time, perhaps one minute, before drinking.  Although toilet flushing or showering flushes water through a portion of your home's plumbing system, you still need to flush the water in each faucet before using it f or \ndrinking or cooking.  Flushing tap water is a simple and inexpensive measure you can take to protect your family's health.  It usually uses less than one or two gallons of water \nand costs less than [insert a cost estimate based on flushing two times a day for 30 \ndays] per month.  To conserve water, fill a couple of bottles for drinking water after flushing the tap, and whenever possible use the first flush water to wash the dishes or water the plants.  If you live in a high- rise building, letting the water flow before using it \nmay not work to lessen your risk from lead. The plumbing systems have more, and sometimes larger pipes than smaller buildings.  Ask your landlord for help in locating the source of the lead and for advice on reducing the lead level.  \nB. Try not to cook with, or drink water from the hot water tap. Hot water \ncan dissolve more lead more quickly than cold water.  If you need hot water, draw water from the cold tap and heat it on the stove.  \nC. Remove loose lead solder and debris from the plumbing materials \ninstalled in newly constructed homes, or homes in which the plumbing has recently been replaced, by removing the faucet strainers from all taps and running the water from 3 to 5 minutes. Thereafter, periodically remove the strainers and flush out any debris that has accumulated over time.  \nD. If your copper pipes are joined with lead solder that has been \ninstalled illegally since it was banned in 1986, notify the plumber who did the work and request that he or she replace the lead solder with lead- free solder.  Lead solder looks \ndull gray, and when scratched with a key looks shiny.  In addition, notify the California Department of Health Services and your local environmental health  department about the violation.  \nE.

You can identify the plumbing contractor by checking the record of building permits which should be maintained in the files of the [insert name of department that issues building permits].  A licensed plumber can at the same time check to see if your home's plumbing contains lead solder, lead pipes, or pipe fittings that contain lead.  The public water system that delivers water to your home should also maintain records of the materials located in the distribution system.  If the serv ice line that connects your dwelling to the water main \ncontributes more than 15 ppb to drinking water, after our comprehensive treatment program is in place, we are required to replace the portion of the line we own.  If the line is only partially owned by  the [insert name of the city, county, or water system that owns \nthe line], we are required to provide the owner of the privately -owned portion of the \nservice line with information on how to replace the privately -owned portion of the service \nline, and offer to replace that portion of the line at the owner\u2019s expense. If we replace only the portion of the line that we own, we also are required to notify you in advance and provide you with information on the steps you can take to minimize exposure to any temporary increase in lead levels that may result from the partial replacement, to take a follow- up sample at our expense from the line within 72 hours after the partial \nreplacement, and to mail or otherwise provide you with the results of that sample within three business days of receiving the results.  Acceptable replacement alternatives \ninclude copper, stainless steel, and plastic pipes.  Partial replacement should avoid the creation of mixed piping systems and include the installation of approved dielectric couplings at all dissimilar metal interfaces.  \nF. Have an electrician check your wiring.  If grounding wires from the \nelectrical system are attached to your pipes, corrosion may be greater.  Check with a licensed electrician or your local electrical code to determine if your wiring can be \ngrounded elsewhere.  DO NOT attempt to change the wiring yourself because improper grounding can cause electrical shock and fire hazards.  \n3. The steps described above will reduce the lead concentrations in your \ndrinking water.  However, if a water test indicates that the drinking water coming from your tap contains lead concentrations in excess of 15 ppb after flushing, or after we have completed our actions to minimize lead levels, then you may want to take the following additional measures:  \nA. Purchase or lease a home treatment device.  Home treatment \ndevices are limited in that each unit treats only the water that flows from the faucet to which it is connected, and all of the devices require periodic maintenance and replac ement.  Devices such as reverse osmosis systems or distillers can effectively \nremove lead from your drinking water.  Since these treatments remove dissolved minerals, water treated by these devices will have a greater tendency to leach lead from brass faucets or fittings which the water contacts after treatment.  Some activated carbon filters may reduce lead levels at the tap, however all lead reduction claims should be investigated.  Be sure to check the actual performance of a specific home treatment device before and after installing the unit.

Lead can pose a significant risk to your health if too much of it \nenters your body.  Lead builds up in the body over many years and can cause damage to the brain, red blood cells and kidneys.  The greatest risk is to young children and pregnant women.  Amounts of lead that won't hurt adults can slow down normal mental and physical development of growing bodies.  In addition, a child at play often comes into contact with sources of lead contamination - like dirt and dust - that rarely affect an \nadult.  It is important to wash children's hands and toys often, and to try to make sur e \nthey only put food in their mouths.  \n1. Lead in drinking water, although rarely the sole cause of lead poisoning, \ncan 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 EPA estimates that drinking water can make up 20 percent or more of a person's total exposure to lead.  \n2. Lead is unusual among drinking water contaminants in that it seldom \noccurs naturally in water supplies like rivers and lakes.  Lead enters drinking water primarily as a result of the corrosion, or 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 \nsome cases, pipes made of lead that connect houses and buildings to water mains (service lines).  In 1986, Congress banned the use of lead solder containing greater \nthan 0.2% lead, and restricted the lead content of  faucets, pipes and other plumbing \nmaterials to 8.0%.  \n3. When water stands in lead pipes or plumbing systems containing lead \nfor several hours or more, the lead may dissolve into your drinking water.  This means \nthe first water drawn from the tap in the morning, or later in the afternoon if the water has not been used all day, can contain fairly high levels of lead.  \n(D) STEPS YOU CAN TAKE.  Steps you can take to reduce exposure to lead \nin drinking water include:   \n1. Let the water run from the tap before using it for drinking or cooking any \ntime the water in a faucet has gone unused for more than six hours.  The longer water resides in plumbing the more lead it may contain.  Flushing the tap means running the cold water faucet for about 15- 30 seconds.  Although toilet flushing or showering flushes \nwater through a portion of the plumbing system, you still need to flush the water in each faucet before using it for drinking or cooking.  Flushing tap water is a simple and inexpensive measure you can take to protect your health.  It usually uses less than one gallon of water.  \n2. Do not cook with, or drink water from the hot water tap.  Hot water can \ndissolve more lead more quickly than cold water.  If you need hot water, draw water from the cold tap and then heat it.  \n3. The steps described above will reduce the lead concentrations in your \ndrinking water.  However, if you are still concerned, you may wish to use bottled water for drinking and cooking.", "start_char_idx": 0, "end_char_idx": 3132, "text_template": "{metadata_str}\n\n{content}", "metadata_template": "{key}: {value}", "metadata_seperator": "\n"}, "__type__": "1"}, "c64f64ba-1fda-4864-8c22-658743faaf99": {"__data__": {"id_": "c64f64ba-1fda-4864-8c22-658743faaf99", "embedding": null, "metadata": {"page_label": "305", "file_name": "CADWReg.pdf"}, "excluded_embed_metadata_keys": [], "excluded_llm_metadata_keys": [], "relationships": {"1": {"node_id": "c04d6dde-804f-44a1-ab1f-1a58d2a76320", "node_type": null, "metadata": {"page_label": "305", "file_name": "CADWReg.pdf"}, "hash": "0d2816f47e64dafe33cfb565fa2ced656264de6325e7a2b159998673d8a24e3f"}}, "hash": "27634b115d117e6b49689359ac9c4b492e99a6ea3d0e8c0b114cec828606879f", "text": "4.

Systems that violate the turbidity MCL of 5 NTU based on an average of \nmeasurements over two consecutive days must consult with the primacy agency within 24 hours after learning of the violation. Based on this consultation, the primacy agency may subsequently decide to elevate the violation to Tier 1. If a system is unable to make contact with the primacy agency in the 24- hour period, the violation is automatically \nelevated to Tier 1.  \n6. Systems with treatment technique violations involving a single exceedance of a \nmaximum turbidity limit under the Surface Water Treatment Rule (SWTR), the Interim Enhanced Surface Water Treatment Rule (IESWTR), or the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR) are required to consult with the primacy agency within 24 hours after learning of the violation. Based on this consultation, the primacy agency may subsequently decide to elevate the violation to Tier 1.

The \nSurface Water Treatment Rule remains in effect for  systems serving at least 10,000 \npersons even after 2002; the Interim Enhanced Surface Water Treatment Rule adds additional requirements and does not in many cases supercede the SWTR.  \n8. The arsenic MCL citations are effective January 23, 2006. Until then,  the \ncitations are \u00a7 141.11(b) and \u00a7 141.23(n).  \n9. The uranium MCL Tier 2 violation citations are effective December 8, 2003 for all \ncommunity water systems.  \n10. The uranium Tier 3 violation citations are effective December 8, 2000 for all \ncommunity water systems.  \n11. The arsenic Tier 3 violation MCL citations are effective January 23, 2006. Until \nthen, the citations are \u00a7 141.23(a), (l).  \n12.
