1.0 INTRODUCTION
This Water Quality Monitoring Plan (WQMP) has been prepared to identify water quality
monitoring and performance measures for the Carlsbad Municipal Golf Course.
Additionally this plan has been designed to satisfy a portion , of the permit processing
requirements of the Califomia Coastal Commission (CCC)(#A-6-CII-0087).
The City of Carlsbad recognizes the importance of sound environmental stewardship, and
is committed to optinuzing its golf course management practices to protect the
environment within, and surrounding, the golf course. This includes protecting the
quality of surface water and groundwater.
A Turf and Pest Management Plan (TPMP)'has also been prepared for the Carlsbad
Municipal Golf Course. This plan emphasizes minimal use of fertilizers, and also calls
for the use of slow releasing fertilizers. Additionally, the plan sets forth guidelines on the
proper time to use fertilizers (not. during a storm event). The TPMP will serve as a first
line of defense in reducing potential water quality impacts, at the Carlsbad Mumcipal Golf
Course.
2.0 PLAN OBJECTIVES
' The objectives of the WQMP for the Carlsbad Municipal Golf Course include:
Establish baseline surface and ground water quality at the golf course.
Establish a water quality monitoring schedule.
Establish reporting requirements for water quality test results.
Identify corrective actions.
Comply with the requirements ofthe CCC Coastal Development permit.

3.0 MONITORING LOCATIONS
The WQMP provide guidance on testing both groundwater and surface water. Locations
for surface and groundwater testing are depicted on Figure 1, and described below.
3.1 Groundwater
A groundwater sampling point, noted as Ai on Figure 1, will be placed at/the upper
portion of Marcario Canyon within the boundaries of the golf course. Another samphng
point, identified as A2 on Figure 1, will, be placed at the lower portion of Marcario
Canyon, -at the westem edge of the golf course.
3.2 Surface Water
A surface water sampling point, noted as Bi on Figure i, has been identified for the upper
portion of Marcario Canyon within the boundaries of the golf course. Another sampling
point, noted as B2 on Figure 1, has been identified within the lower portion of Marcario
Canyon, at the westem edge ofthe golf course.
4.0 SAMPLE COLLECTION, TIMING, AND FREQUENCY
4.1 Pre-Construction (Baseline) Groundwater Monitoring
Monitoring wells will be installed in the locations identified in Section 3.1. Monitoring
site A] is assumed to be outside the golf course area of influence, while monitoring site
A2 is located at the downsfream boundary ofthe golf course.
Sampling for baseline data for groundwater shall also be conducted a minimum of three
times and during different level of storm events (including dry) to acquire a
representative sample of'water quality conditions at the site. Samples shall be collected
and submitted for testing on a quarterly basis until active application of fertilizer to the
golf course begins. The samples will be tested per the parameters identified in Section
8.0, and data acquired, from this unit of testing will be used to establish groundwater
baseline measurements for these parameters.
Baseline testing will also identify any natural upstream and downstream differences in
groimdwater as it passes through the undeveloped project site.

4.2 Post-Construction Groundwater Monitoring
Samples will be collected from the locations identified in Section 4.2 and submitted for
testing within three months after the first fertilizer and/or pesticide apphcation has been
made to -the golf course, and quarterly thereafter. Samples will be tested per the
parameters identified in Section 8.0.
4.3 Pre-Construction (Baseline) Surface Water Monitoring.
Sampling for baseline data for surface water shall also be conducted a minimum of three
times and during different level of storm events (mcluding dry weather) to acquire a
representative sample of water quality conditions at the site. Samples shall be collected
and submitted for testing on a quarterly basis until active application of fertilizer to the
golf course begins. The samples will be tested per the parameters identified in Section
8.0, and data acquired from this unit of testing will be used to establish surface water
baseline measurements for these parameters.
Baseline testing will also identify any natural upstream and downstream differences in
surface water as it passes through the undeveloped project site.
4.4 Post-Construction Surface Water Monitoring
Samples will be collected from the locations identified in Section 4.2 and submitted for
testing within three months after the first fertilizer and/or pesticide application has been
made to the golf course, and quarterly thereafter. Additionally, three samples will be
taken during various-level,storm events each year when visible mnoff reaches the creek.
One dry weather sample will be" taken each year. Timing of sampling should be shortly
after an irrigation cycle has been completed, with the intent that if mnoff is occurring into
the creek, sampling will identify mnoff constituents. Samples will be tested per the
parameters identified in Section 8.0. '
5.0 SAMPLE COLLECTION
Samples will be collected and transported to testing laboratories by a service separate
from, and designated by, the City of Carlsbad that has fraining in proper sample
collection.-
City of Carlsbad Municipal Golf Course
Water Quality Monitoring Plan
6.0 CHAIN-OF-CUSTODY
I Chain-of custody will be documented for all samples from the point of sample collection
to the point of sample receipt by the testing laboratory. - ^
7.0 SAMPLE MAINTENANCE AND TRANSPORT
All laboratory test resuhs will be linked by the laboratory sample identification number
and the Carisbad Municipal Golf Course identified assigned to the sample at the time of
sample collection.
After coUection, samples will be stored at 4° C (-39° F) in the dark. Samples will be
maintained at 4° C during ttansports to the testing laboratory and will be delivered to the
testing laboratory no more than twenty-four hours following sample collection.

Therefore, nutrients associated with fertilizers will form the basis of the samphng
program. Using the appropriate United States Environmental Protections Agency (EPA)
testing method, water samples will be tested for the parameters identified in Sections 8.1
through 8.6' of this plan. EPA testing methods are available on-line at;
http://www.epa.gov/epahome/index/.
8.1 Nitrates and Nitrites
Nitrites and nitrates are a major constituent in fertilizers. Nittogen fertihzer will be
periodically applied to the portions of golf course turf as part of the turf management
plan. Nitrate and nitnte are inorganic forms of nitrogen in the aquatic environment.
Nitrate along with ammonia are the forms of nittogen used by plants. Nitrates and nitntes
are formed through the oxidation of ammonia by nitrifying bacteria, a process known as
nitrification. In tum they are converted to other nitrogen forms by denitrification and
plant uptake.
-Nitrites can produce a serious condition in fish called "brown blood disease." Nitrites also
react directly with hemoglobin in human .blood and other warm-blooded animals to

Water Quality Monitoring Plan
produce, which desfroys the ability of red blood cells, to fransport oxygen. Nitrites
convert to nifrates quickly through contact with bacteria in water.
Nitrates are nifrogen-oxygen chemical units that combine with various organic and
inorganic compounds. They are essential nutrients for plants, which absorb them from
soil. The excess nifrates not used by the plants are carried through the soil to ground
water in a process Called "leaching." Nittate reactions in fresh water can cause oxygen
depletion. Thus, aquatic organisms depending on the supply of oxygen in the stream will
die.
Both surface water and groundwater will be analyzed for nitrates and nitrites.
8.2 Total Phosphorus
Phosphoms fertilizer will be periodically applied to portion of the course turf, as
identified in the Turf and Pest Management Plan. Phosphates stimulate the growth of
plankton and aquatic plants which provide food for fish. This increased'growth may
cause an increase in the fish population and improve the overall water quality. However,
if an excess bf phosphate enters the waterway, algae and aquatic plants will grow wildly,
choke up the waterway and consume large amounts of oxygen. This condition is known
as eutrophication or o.ver-fertilization of receiving waters. The rapid growth of aquatic
vegetation can cause the death and decay of vegetation and aquatic life because of the
decrease in dissolved oxygen levels. No state of federal criterion for total phosphoms has
been recommended for the protection of either freshwater or saltwater aquatic life.
Both surface water and groundwater will be analyzed for phosphoms.
8.3 Dissolved Oxygen
Dissolved oxygen is the amount of oxygen dissolved in water, measured in milligrams
per liter (mg/L). This component of water is critical to the survival of various aquatic life
in streams, such as fish. The ability of water to hold oxygen in solution is inversely
proportional to the temperature of the water. For example, the cooler the water
temperature, the more dissolved oxygen it can hold.
Surface water will be analyzed for dissolved oxygen.

1 i 8.4 Hydrogen-Ion Activity (pH)
pH provides a measure, on a scale from 0 to 14, ofthe acidity or alkalinity ofa solution,
where 7 is neutral, greater than 7 is acidic, and less than 7 is basic). The pH of the water
is important because it affects the solubility and availability of nutrients, and how they
can be used by aquatic organisms. The EPA Water Quality Criteria for the protection of
freshwater aquatic hfe ranges from 6.5 to 9.0 units
pH will also be monitored on the golf course, and the additional of acid or alkaline, may
be required in order to optimize the take up of nutrients by the turf.
Both surface water and groundwater will be analyzed for pH.
8.5 Total Suspended Solids (TSS)
Total Suspended Sohds (TSS) is a measure ofthe suspended organic and inorganic sohds
in water. Suspended solids are deleterious to benthic organisms and may cause the
formation of anaerobic conditions. They can clog fish gills and interfere with respiration
in aquatic fauna. They also screen out light, hindering photosynthesis and normal aquatic
plant growth and development.
Both surface water and groundwater will be analyzed for TSS.
8.6 Acute and Chronic Toxicity
Toxicity is the adverse response of organisms to chemical for physical agents. Acute
toxicity is the ability of a substance.to cause harmful effects soon after a single exposure
or dose. Chronic toxicity is the effect of repeated or long-term exposure to a substance.
Both surface and groundwater will be analyzed for toxicity.
Toxicity will be assessed using the water flea, Ceriodaphnia dubia, in accordance with
methods recommended by the EPA. The test procedure consisted of exposing 10 C.
dubia neonates (less than 24 hours old) to the samples for six days.

9.0 INTERPRETATION OF RESULTS
For all parameters identified in Section 8.0, post-constmction test results will be
compared to pre-established baseline values. For nifrates, nitrites, total phosphoms,
dissolved oxygen, and total suspended solids, a change of 15 % between the baseline data
and the data gathered during project constmction/operation will be considered significant.
The comparison ofthe baseline and project constmction/operation samples may need to
be adjusted to reflect natural variability in samples. For example, if baseline data taken
before project constmction identifies a variability in the upper and lower sample sites, a
condition that occurs before the project is developed, then, this variability would also be
considered in the final interpretation of results. After this adjustment is made, if required
based upon the baseline data, then a change of 15%) or greater would require the
adherence to procedures in Section 11.0 of this plan. • .
For pH, the results should be within the 6.5 to 9.0 range. Results outside this range will
require adherence to procedures in Section 11.0 of this plan. For the toxicity tests, if
mortality results exceed accepted standards, the procedures in- Section 11:0 will be
followed.
10.0 DOCUMENTATION
All activities associated with the Carlsbad Municipal Golf Course Water Quality
Monitoring plan will be documented, including sample collection, chain-of-custody, test^
results, interpretation of results, and summary reports. All original documents will be
maintained onsite at the Carlsbad Municipal Golf Course: Water quality monitoring
reports summarizing laboratory testing results will be prepared following each round of
testing (i.e., quarterly).
An annual summary report shall be submitted to the Executive Director of the CCC.
11.0 CORRECTIVE ACTION
In the event that water quality threshold levels are exceeded, the City of Carlsbad shall
notify the Executive Director of the CCC within 48 hours. The notification shall detail
the exceedence and potential impacts. At this .time, the City shall also consuh with the
•")
Executive Director regarding the need for additional sampling to' evaluate the exceedance
or corrective action to .'minimize water quality impacts. The, City shall report to the
City of Carlsbad Municipal Golf Course g Water Quality.Monitoring Plan
Executive Director on the possible causes of the exceedance and proposed corrective
actions within 30 days of the initial receipt of data.
In the event that water quality impacts. persist after three years of detection, not
withstanding any corrective action taken by the City, all use of the chemicals that area
contributing to the exceedance of water quahty threshold levels shall cease.
12.0 REVIEW AND UPDATE OF WQMP
This document should be considered flexible, and shall be periodically reviewed to
ensure that the most current water quality monitoring protocol are being implemented.
This could include sampling locations, constittients monitored, sampling schedule, and
analysis criterion. No changes shall be made to this plan without approval by the
Executive Director of the CCC. •
