<br />constituents, total chlorine residual, has an affect the appearance, taste and smell of wa-
<br />MRDL (maximum residual disinfection level) ter, but do not affect the safety of the water
<br />instead of an MCL. unless they also have a primary standard.
<br />The MRDL is the maximum level of a disin-
<br />fectant added for water treatment that is
<br />allowed in water. While disinfectants are
<br />necessary to kill harmful microbes, drinking
<br />water regulations protect against too much
<br />disinfectant being added. Another constitu-
<br />ent, turbidity, has a requirement that 95
<br />percent of the measurements taken must
<br />be below a certain number. Turbidity is a
<br />measure of the cloudiness of the water. We
<br />monitor it because it is a good indicator of
<br />the efficiency of the filtration system.
<br />4. Why are some of the constituents listed
<br />in the section labeled "Primary Stan-
<br />dards" and others in the "Secondary
<br />Standards"?
<br />Constituents that are grouped in the primary
<br />standards section may be unhealthy at cer-
<br />tain levels. Constituents that are grouped
<br />5. How do I know how much of a constituent is
<br />in my water and if it is at a safe level?
<br />With a few exceptions, if the AVERAGE
<br />amount of a constituent found in tap water
<br />over the course of a year is no greater than
<br />the MCL, then the regulatory requirements
<br />are considered to be satisfied. The highest
<br />and lowest levels measured over a year are
<br />shown in the RANGE. Requirements for
<br />safety, appearance, taste and smell are
<br />based on the AVERAGE levels recorded
<br />and not the RANGE.
<br />6. How do constituents get into our water?
<br />Drinking water (both tap water and bottled
<br />water) comes from rivers, lakes, streams,
<br />ponds, reservoirs, springs and wells. As water
<br />travels over the surface of the land or through
<br />the ground, it dissolves naturally occurring
<br />minerals and, in some cases, radioactive ma-
<br />terial, and can pick up substances resulting
<br />from the presence of animals or from human
<br />activity. The most likely source for each con-
<br />stituent is listed in the last column of the table.
<br />7. Are there any potential sources of
<br />contamination in our system?
<br />An assessment of the drinking water wells
<br />for the City of Santa Ana was completed in
<br />December 2oo6. The City wells are consid-
<br />ered most vulnerable to the following activi-
<br />ties associated with contaminants detected
<br />in the water supply: historic agricultural ac-
<br />tivities, golf courses, and application of fertil-
<br />izers. The Citys wells are considered most
<br />vulnerable to the following activities not asso-
<br />ciated with detected contaminates: chemical/
<br />petroleum pipelines, chemical/petroleum
<br />processing/stores, dry cleaners, gas stations,
<br />junk/scrap/salvage yards, metal plating/
<br />finishing/fabrication, plastics/synthetics pro-
<br />ducers, and sewer collection systems.

<br />IMPORTANT INFORMATION ABOUT DRINKING WATER
<br />Monitoring Requirements Not Met For The City of Santa Ana
<br />There are many monitoring requirements
<br />imposed on every pub] is water system. Our
<br />water system staff failed to adequately meet
<br />these requirements on one occasion this past
<br />year, and therefore the City's water system
<br />was in violation of these regulations. It is im-
<br />portant to note that this was not a violation
<br />caused by having contaminants exceed allow-
<br />able levels, rather it was a violation caused
<br />by failing to take the required number of
<br />samples within a specific time frame. Even
<br />though this failure was not an emergency, as
<br />our customers, you have the right to know
<br />what you should do, what happened, and
<br />what we did to correct this situation. This
<br />notice is intended to provide you with this
<br />information.
<br />We are required to monitor your drinking
<br />water for specific contaminants on a regular
<br />basis. Results of regular monitoring are an
<br />indicator of whether or not our drinking water
<br />meets health standards. During a period of
<br />April 22 to 26, 2o2o, we did not take the re-
<br />quired number of repeat bacteriological sam-
<br />ples required under Title 22 California Code of
<br />Regulations, Section 64424 (c), and therefore
<br />cannot be sure of the quality of our drinking
<br />water during that time.
<br />What should I do?
<br />i. There is nothing you need to do at this time.

<br />did not property test for during the last

<br />"Academy Awards of Water," the competition
<br />is the largest and longest running water tast-
<br />ing in the world dedicated to preserving and
<br />protecting drinking water.
<br />Similar to a wine tasting, a dozen judges were
<br />asked to taste water from nearly ioo different
<br />sources, rating the water for
<br />each attribute including ap-
<br />pearance (should be clear),
<br />aroma (should be none), taste
<br />(should taste clean), mouth
<br />feel (should feel light), and
<br />aftertaste (should leave you
<br />take and how often, how many samples we
<br />took, when samples should have been
<br />taken, and the date on which follow-up
<br />samples were taken.
<br />What happened? What is being done?
<br />We have provided additional training to our
<br />staff so that there is no misunderstanding in
<br />the proper time frame and amount of repeat
<br />samples required when a positive bacteriologi-
<br />cal sample has been reported by the laboratory.
<br />We have performed and continue to perform
<br />all of the required water system monitoring
<br />required under Title 22 to ensure the water
<br />provided to our customers is in full compliance
<br />with all regulations. For more information,
