ABSTRACT
Development and Implementation of a Water Quality Monitoring Plan to Support the Creation of a Geographic Information System to Assess Water Quality
Conditions of Rivers in the State of Veracruz in Mexico
Miguel A. Medina Department of Civil and Environmental Engineering, BYU
Master of Science
Geographic information has always played a crucial role in the decision making process of many fields because the visual nature of the information adds important understanding that translates into better decision making. A Geographic Information System (GIS) integrates computer software and data to visualize, understand, and use information in many ways. A GIS stores many different types of information, including environmental and water quality information. Regardless of what type of information is to be used within a GIS, the information must be properly gathered using a systematic approach.
For this project, a water quality monitoring plan was developed and implemented at the
University of Veracruz (UV) to collect water quality data to assist the creation of a GIS. This GIS will support the decision making process in environmental concerns at a watershed level for some of the main rivers in the state of Veracruz in Mexico. This GIS will also serve as a tool to monitor and evaluate river conditions over time and at different locations, determine sources of contamination, identify solutions to mitigate effects of contamination, and to present the results to interest groups.
This plan considered the acquisition of water quality monitoring equipment, training of a
group of environmental engineering students, and determining monitoring points along the rivers and the logistics accompanying monitoring at those points. The water quality data that was produced as a result of this project can be used as input data for a GIS, and will also be a source of information for other environmental and water resources agencies. Furthermore, this plan played and will continue playing an important role in educating environmental engineering students at the UV who will learn and benefit from this project.
The plan was successfully implemented at the UV and it included a set of methodologies
and guidelines to standardize the work to be performed by the students. It also made a very positive impact as it stimulated the interest of students and faculty to continue working on this project and in other similar projects in the long run.
Keywords: geographic information systems, decision support system, input data, water quality data, CONAGUA, CIATEJ, UV, monitoring points, monitoring plan, water quality parameters.
ACKNOWLEDGMENTS
This work and the opportunity I had to be part of it would not have been possible without
the help and support of my professor and advisor, Dr. E. James Nelson. I thank him for helping
open doors for me and for the development of this project, for his guidance, for trusting me, and
for his concern in water resources-related projects in developing countries.
I thank the Mosaic Foundation and the CEEN Department at BYU for their interest in
water resources-related projects and for providing the funds needed to purchase the equipment
for this project.
I thank my friend and colleague Dr. Gustavo Davila, researcher at CIATEJ, for the data
provided for this project, for the equipment and laboratory supplies donated, and for his
continuous support during the development of the project. I thank Dr. Miguel Morales, professor
at the University of Veracruz (UV), for being the link between BYU-CIATEJ and the UV, and
for his overall invaluable help and support at the UV. I also thank the amazing group of students
and professors at the UV who have been involved directly or indirectly in this project for
providing invaluable help and support during its implementation; without them, this project
would not have been possible.
I thank my parents for everything they do and have done for me, and for their
unconditional support. And last but not least, I thank God, knowing that words would never be
enough to express my gratitude.

1 INTRODUCTION
Geographic Information Systems (GIS) are setting new standards on how we manage
information in engineering and many other fields; they integrate information technology tools
with geographic tools to visualize and analyze data that aid in making educated decisions. The
amount and accuracy of information will determine the quality of the decisions we make in many
engineering and environmental fields. A GIS stores and manages geographic-related information
of any type including environmental and water quality information which can later be used as
part of a Decision Support System (DSS).
This project consists of the development and implementation of a water quality
monitoring plan to collect water quality data to assist the creation of a larger GIS which will be
used as a DSS at a watershed level for some of the main rivers in Veracruz, Mexico. The rivers
that will be monitored in this project are the Cazones River, the Tuxpan River, and the Tecolutla
River. The project will focus on gathering and monitoring water quality data which can later be
used as input data for the GIS previously mentioned.
This project considers the acquisition of water quality monitoring equipment that will be
used to gather data directly in the field and in the laboratory, training for students who will be
collecting the data, and the logistics involved in the work.
The objectives of this project are to develop a water quality monitoring plan that includes
fixed guidelines and methodologies to gather and process data; to train environmental
engineering students at the University of Veracruz and provide them with hands-on experience;
2
to provide reliable water quality data of the rivers that comprise the area of study so that it can be
used as input data for a GIS or for other applications; and to create an ongoing program
conducted by students and faculty members at the University of Veracruz (UV) to monitor water
quality in critical bodies of water and thus create a highly positive academic impact.
As mentioned previously, this water quality monitoring plan will also assist the creation
of a larger GIS which ultimately will serve as a tool to monitor and evaluate environmental and
water conditions over time at a watershed level. This GIS will also help to determine sources of
contamination, to develop action plans to mitigate the effects of contamination, to identify
technical solutions, and to present the results to groups of interest.

2 GEOGRAPHIC INFORMATION SYSTEMS (GIS)
Technology plays a crucial role in most decision making processes; nowadays,
Geographic Information Systems (GIS) are setting new standards on how we manage
information in engineering and in many other fields, and for this project it is important to
understand the importance and applications of GIS. GIS integrates information technology tools
with geographic tools which allow us to visualize, understand, use, and analyze data to make
educated decisions.
2.1 Importance of Geographic Information
Throughout history, geographic information has been used in countless applications all
over the world, and history has shown that knowledge and information will always give us a
significant advantage in any field.
Geographic information is usually represented in maps, which is something we owe to
cartography. Cartography is the discipline of map making and has always been a part of human
history due to our human need to represent and understand our surroundings. Cartography and
the use of geographic information have evolved from rudimentary two dimensional drawings to
comprehensive Geographic Information Systems that integrate computer hardware, software,
geographic tools, and large amounts of data.
The amount and accuracy of information determines the quality of the decisions we
make. A GIS stores and manages geographic related information of any type such as
4
environmental and water quality information that can later be used as part of a DSS. The use of a
DSS can be compared to putting all the needed information regarding an area of study on a table
in front of us so we can see the big picture and analyze every component individually as needed,
and then, make educated decisions regarding the area of study.
2.1.1 Components of a Geographic Information System
A GIS allows us to analyze every possible map and any type of information that could
not be represented graphically in a traditional map or earth model. Similar to a traditional map, a
GIS uses coordinate systems and scales to display the geographic data. It also allows us to
analyze data in many ways so we can reveal trends, relationships, patterns, etc. [1].
Basically the components of a GIS are computer hardware, software and spatial data.
Computer hardware refers to the computer in which a GIS operates and the software refers to the
software package that operates as a database management system.
The data within a GIS are stored in geodatabases. A geodatabase may contain datasets
which are smaller collections of data. Within a geodatabase there are layers or coverages of
information, and depending on the GIS program used these layers are known as feature classes
which are homogeneous collections of common features. A geodatabase may also contain raster
datasets and tables of information [1]. A map generated from a GIS is a group of feature classes
or layers of information overlapping each other in a similar way Computer-aided Design (CAD)
programs organize information.
Each geographic object in a layer is called a feature, and depending on what each object
represents in real life, it can use polygons, lines, or points. For instance, a city, a lake, or a
country can be represented using a polygon, a river can be represented using a line, and trees can
be represented using points. These objects collectively are called vector data.
5
Surfaces, on the other hand, represent a vast continue expanse that change continuously
from one location to another. Unlike features, surfaces have no distinct shape, rather they have
measurable values such as temperature, rainfall, depth, etc.; a common example of a surface used
within a GIS would be a raster dataset representing the elevations in the sea. While features use
vector data to represent geographic objects, surfaces use data known as raster data to represent
values that change from one location to another and have numeric values rather than shapes;
these numeric values are stored in a grid-like format in a raster dataset.
Features not only have shapes but also additional information regarding the object they
represent in real life. A GIS can store and manage any type of information regarding the area of
study and this information is stored in tables. A table contains different categories of
information, these categories are called attributes. Within a table, attributes are shown in
columns and each record of information for each feature is presented as a row within the table.
2.2 Applications of GIS
As mentioned before, a GIS is used to present information to aid the decision making
process in a variety of fields. The applications of GIS are too broad, from the creation of
professional maps to the prediction of flooding events and landslides when data and trends are
analyzed. GIS are used in many industries such as business, education, defense and intelligence,
public safety, transportation, utilities and communications, natural resources, water resources,
etc. In the field of water resources, GIS are used for watershed management, flood management,
groundwater, water quality, etc. [2].
The focus of this project is to develop a water quality monitoring plan that will generate
data that can be used in a GIS for the area of study. The resulting GIS will serve as a DSS for the
6
area of study. Similar projects have been developed over the years; an example of one of those
projects was the assessment of the state of the Yellowstone River’s ecosystem, the prediction of
its future conditions, and the distribution of data to decision makers.
The goals of this project were to develop best management practices for managing the
river and to collect geospatial data and produce a continuous terrain model of the river channel
floodplain. For this project the U.S. Army Corps of Engineers (USACE), Omaha District, and
the Yellowstone River Conservation District Council entered into an agreement to perform the
needed studies to assess the river conditions.
The obtained results included three specific scopes of work which were: scientific
analysis of hydraulics, hydrology, and geomorphology. In addition, some of the information
gathered would serve other purposes because it also included information about vegetation,
wetlands, water quality, etc.
This great task could not have been accomplished efficiently without the use of GIS. GIS
provided the tools needed to visualize the information gathered so the river conditions could be
assessed. This information would eventually be used in the decision making process for future
works in the river area [3].
2.3 Applications of GIS in Mexico
In Mexico there are government agencies and private companies working with GIS to
improve the country’s cartography, distribute geographic data, and analyze data for research
purposes. The government agencies working with GIS in Mexico are agencies similar to the U.S.
Geological Survey (USGS), or the National Geophysical Data Center (NGDC) which is a part of
National Oceanic & Atmospheric Administration (NOAA). In Mexico the main government
7
agencies working with GIS are the National Institute of Statistics and Geography (INEGI), and
the National Council on Science and Technology (CONACYT). Furthermore, there are also
some other agencies and research institutes that are part of CONACYT who are working with
GIS in the country.
2.4 Applications of GIS in the Area of Study: Veracruz, Mexico
The Center for Research and Applied Technology in Jalisco (CIATEJ) is part of
CONACYT, and is a research institute that is currently working in the development of a DSS at a
watershed level for controlling sources of contamination in the Tuxpan, Cazones, and Tecolutla
Rivers in Veracruz, Mexico. This DSS will be GIS-based and will contain hydrologic, land use,
soil type, and water quality data; with the latter being the focus of this project [4].
2.4.1 Creation of a GIS-Based Decision Support System in the Area of Study
The area of study comprises the watersheds for the Tuxpan, Cazones, and Tecolutla
Rivers. For each river, the GIS-based DSS will help determine the point and non-point sources of
contamination, manage the monitored water quality data, develop water quality models, evaluate
water quality conditions, aid in the development of action plans to mitigate contamination, and
present the results to groups of interest [4].

3 WATER QUALITY
Water quality can be defined as the physical, chemical, and biological characteristics of
the water. Depending on what a water stream or a water body is to be used for, different
regulations regarding water quality apply to it, e.g., a water stream used to cool down power
generators will have different water quality requirements than a water stream used for irrigation
purposes.
3.1 Importance of Monitoring Water Quality
The river-water in the area of study is mainly for public use and irrigation purposes;
therefore, its quality needs to be monitored constantly to ensure it meets the requirements
established by the official environmental regulations in Mexico and to detect when the water
quality is unsatisfactory.
Since the rivers in the area of study are considered by Mexican laws national waters, the
Official Mexican Standard (NOM) NOM-001-ECOL-1996 applies to them. This NOM
establishes the maximum permissible limits of contaminants and heavy metals as shown in Table
3–1 [5].

For these rivers, the National Commission of Water (CONAGUA) has been monitoring
the following water quality parameters: Conductivity, Dissolved Oxygen, pH, Sulfates,
Turbidity, Chlorides, Biochemical Oxygen Demand, Phosphates, Ammonia Nitrogen, Nitrate
Nitrogen, Total Dissolved Solids.
For this project we monitored the same 11 physical and chemical water quality
parameters; this was also for the purpose of developing water quality indices for each river to
determine the overall conditions of the rivers.

3.3 Water Quality Index
A Water Quality Index (WQI) is a weighted average that comprises a number of water
quality parameters into one single number. This index was developed by the National Sanitation
Foundation (NSF) as a method to evaluate the overall water quality conditions in a water body.
The WQI is calculated by using the following common water quality parameters: dissolved
oxygen, fecal coliform, pH, BOD5, total phosphorus, nitrates, turbidity, temperature, and total
dissolved solids. The values in a WQI range from 0 – 100 and these values express the overall
water quality conditions. Values in the range 90 – 100 express excellent conditions, 70 – 90
express good conditions, 50 – 70 express medium conditions, 25 – 50 express bad conditions,
and values in the range 0 – 25 express poor conditions. [4]
With the data provided by CONAGUA, CIATEJ produced a WQI for each monitoring
point for the 1999-2008 periods. These WQI were created using the methodology proposed by
the NSF and online tools. CIATEJ also delineated the contributing watershed for each river using
Digital Elevation Maps (DEM) and the Watershed Management System (WMS) program to
present the information to groups of interest [4]. Figure 3–2 to Figure 3–7 show the WQI
CIATEJ calculated at each monitoring point along the rivers and their variations with time.

4 METHODOLOGY
The focus of this project is the development of a water quality monitoring plan. This plan
consists of the methodology followed to produce data that can be used in a GIS or other database
management system.
4.1 The Need for a Systematic Plan
In order to develop an efficient monitoring program, a methodology must be followed to
minimize errors and to standardize operations. This will also help to reproduce this plan in other
institutions or to monitor water quality in other water bodies and to ensure homogeneity of
results despite the high rotation of students working on similar projects.
A plan was first presented at the UV in March of 2010 as part of the activities of the
Mexico Engineering Study Abroad (MESA) program. When the plan was presented, we knew
what water quality parameters were going to be monitored and where the monitoring points were
but we were not sure how we would actually implement the plan because we did not know the
area; as time went by we made some changes and the logistics also had to be worked out.
In July 2010 and March 2011 I visited the students at the UV to follow up. In July 2010 I
went by myself and joined them for a day of field work and in March 2011 I accompanied
personnel from CIATEJ and joined the students in three days of field work. During those visits I
noticed that they were doing things differently and that there were new students working in the
program who didn’t know how to use the equipment. I also started noticing inconsistencies in the
18
data they were reporting periodically. This made evident the need for a standardized
methodology of work similar to the methodologies followed at the Civil and Environmental
Engineering (CEEN) department at Brigham Young University (BYU) for monitoring water
quality in water bodies like Deer Creek in Utah [6].
4.2 Monitoring Points
The criteria to select monitoring points for this project was to select points that would
represent the overall conditions of the water quality in the rivers; some of these points are located
upstream right before communities with a population above twenty-five hundred people, and
some points are downstream right before the same communities, and some points are located in
between communities. This was to help determine how the water quality varies along the river in
the upstream and downstream directions. Also, the location for some points is similar to the
location of some of CONAGUA’s monitoring points, and this was so that we could have a
reference to compare the results and monitor the variations in water quality with time.
4.2.1 Location of Monitoring Points
CONAGUA has 9 monitoring points in the area of study, 4 points along the Tuxpan
River, 3 points along the Cazones River, and 2 points along the Tecolutla River; the names and
coordinates of these points are shown in Table 4–1. For this project, 18 monitoring points were
selected, 3 points along the Tuxpan River, 6 points along the Cazones River, and 9 points along
the Tecolutla River. For each river, the points are numbered from the upstream to downstream
direction. Table 4–2 shows the names and coordinates of the monitoring points selected for this
project and Figure 4–1 to Figure 4–3 show the aerial view of the location of these points.

4.3.1 List and Description of the Equipment
After considering and evaluating different options for water quality monitoring
equipment, we decided to buy equipment from the company HANNA, which is a company that
offers environmental and laboratory equipment at more affordable prices in comparison to some
leading companies like HACH or YSI. Table 4–3 shows a list of the equipment we bought for
this project and a brief description of it while Figure 4–4 and Figure 4–5 show the type
equipment we bought.
4.3.2 Operating Expenses
This water quality monitoring program is an ongoing project which makes it important to
consider the operating expenses in the long run. Buying the equipment was just an initial
expense, the equipment was purchased through a grant donation from The Mosaic Foundation
and it was later donated to the UV for ongoing and future work [7]. Upon receiving the
equipment, the team at the UV began being fully responsible for it and all the associated
expenses when using the equipment. At first, this was a concern since the university would have
to absorb all of the expenses; however, CIATEJ has supported this project by donating
laboratory equipment such as plastic and glass laboratory bottles and standards to calibrate the
equipment.
After over a year and a half since we started the project, the engineering department at
the UV has received support and resources from CIATEJ and the UV to continue working with
this project.

4.4 Training
Training is an essential part of this program, especially because one of the main
objectives of this project is to train Environmental Engineering students at UV on how to operate
water quality monitoring equipment and implement an ongoing program to collect water quality
data.
Before our first visit in March 2010, our BYU team spent time learning how to use the
equipment because we would train a group of students at the UV. During our first visit we spent
some hours on our first day training students before heading to the field and we also spent time
training them in the field; Figure 4–7 is a picture taken on our first day in the field while training
students. In March 2011, one year later, there were new students working on this project who
were not familiar with GIS, monitoring water quality, or using water quality monitoring
equipment so I gave them a presentation about GIS and trained them on how to use the
equipment.
It is worth mentioning that most of the UV students involved in this project did not have
previous experience operating water quality monitoring equipment but they showed full interest
as they were taught how to use it. These students were also volunteers who found the time to
work on the project between their classes or on their spare time. Likewise, some of the professors
working with the group of students involved in the project were taught how to use the equipment
and they were also able to work off the clock.

4.5 Field and Laboratory Work
For this project it is important to combine field and laboratory work to produce reliable
results. Logistics also play an important role when combining field and laboratory work. We
established that monitoring campaigns would be done every three months so we can obtain data
during different seasons of the year.
Many of the changes we implemented at the UV were made after the work methodologies
followed at BYU when monitoring water quality in places like Deer Creek.
4.5.1 Field Work and Logistics
Most of the work for this project is performed in the field; therefore, it is very important
to be efficient in order to optimize the time spent in the field. In March of 2010 we did a rough
estimate of driving distances and times to cover all the points but we didn’t know the area and
the conditions of the roads, also we didn’t take into account that working with inexperienced
students would require more time.
When we started working on this program we would go to the first monitoring point,
measure all of the parameters there, then go to the next point measure all of the parameters and
do the same for all the points. Starting in March 2011 we changed this and decided to measure in
the field the parameters that needed to be measured in-situ and take samples back to the
laboratory to measure the rest of the parameters.
We established this as a standard of work. We bought about ten one-liter plastic bottles
on March 2011 to transport the samples back to the laboratory at the UV; however, these bottles
were not laboratory bottles, they were just plastic bottles we bought at a local store. In October
2011 CIATEJ donated about 20 laboratory plastic bottles, half dark glass bottles, half incubation

and graphs that update automatically once new values are entered. This is a practical and easy
way to see if the values reported are consistent and to see if they follow a trend. From these
spreadsheets students can print out a template to take with them and easily detect possible
inconsistencies when the readings vary dramatically from the previous field trip at the same
point. This new template also indicates the units in which each parameter must be measured.
Table 4–4 is the template used to collect data for this project and Appendix A through Appendix
C show all the actual data recorded and reported by the UV for each of the monitoring points.

5 DATA ANALYSIS AND PROCESSING
5.1 Pre-Processing and Post-Processing
Since one of the objectives of this project is to produce data that can be used as input data
in a GIS and further applications, the data collected at the field and in the lab needs to be
analyzed to detect inconsistencies. The use of a template helps to reduce inconsistencies because
it shows the units in which each parameter must be measured and reported. The equipment used
for this project allows the user to choose the display units and a common mistake was that some
readings were reported in parts per million (ppm) or mg/L one time and the next time they were
reported in parts per billion (ppb), such was the case when reporting chlorides content. Another
error was reporting conductivity in units of micro-siemens (µS/cm) one time and then using
milli-siemens (mS/cm), or reporting resistivity in micro-ohms (µΩ) one time and then milli-
ohms the next time (mΩ).
Once the data were collected I made corrections where it was easy to see that the wrong
units were used e.g., when reporting using units of ppb instead of ppm; however, some values
remain as they were reported even when they might be inconsistent.
5.2 Discussion of Results
The data collected so far represent a year and a half of work, and six monitoring trips.
The data collected might have inconsistencies or might not be complete; the main reasons for
36
these inconsistencies are most likely inadequate use of the equipment, lack of calibration of the
equipment, and lack of maintenance of the equipment.
Due to the rotation of personnel working on this project at the UV, some students didn’t
really know how to use the equipment and they may have not used it properly which affects the
quality of the results, also with time some of the standards used for calibration got contaminated
or are about to expire which produces inaccurate calibration, and finally, since we bought the
equipment in March 2010 it has not received any type of maintenance even when it is
recommended to give the equipment maintenance at least every six months, and this also affects
the quality of the results.
However, in order to evaluate the consistency of the results produced I took some random
points and compared the results reported by CONAGUA from three different years with the
results we are reporting over a period of one year. The points I am comparing are Puente Alamo
which is one our points with Alamo-Jugueras and Alamo which are two points monitored by
CONAGUA. These points are within a distance of 5 kilometers from each other; Alamo-
Jugueras is about 4 km upstream of Puente Alamo and Alamo is about 5 km downstream of
Puente Alamo. The time periods used for the comparisons are about a year starting during the
Spring and going to the next Spring the following year. For these points the periods compared
are: Spring 2004 – Spring 2005 for Alamo-Jugueras, Spring 2006 – Spring 2007 for Alamo-
Jugureas, and Spring 2010 – Spring 2011 for Alamo.
A total of 10 parameters were analyzed to determine how consistent the values were in
comparison to values reported in previous years for the same place. Figure 3–1 shows the
variations in Dissolved Oxygen for the previously mentioned monitoring points and periods, this
graph shows that most values are within a ±3 unit margin which can be used to consider that the
37
values reported by the UV are valid. A similar analysis was performed for the Lazaro Cardenas
monitoring points in the Tecolutla River. Appendix D through Appendix F contains the complete
results of these analyses and they show that most results are within a reasonable margin.
However, there are results for some other points that might be inconsistent due to the reasons
previously mentioned.

5.3 Further Use of Data
As mentioned before, the data produced can be used as input data for a GIS, it also can be
stored in a database that can be shared with students, research organizations, other universities,
etc. The data can be shared and operated in a similar way the Consortium of Universities for the
Advancement of Hydrologic Science, Inc. (CUAHSI) shares and manages data. The data can
also be used in database management software like ArcHydro and/or shared using servers like

water quality computer models like QUAL2K to perform water quality simulations. Further
sharing of the data and its use for modeling purposes are out of the scope of this project.

6 ACADEMIC IMPACT AND FUTURE GOALS
This is an ongoing project that had a positive impact at the UV already and it will
continue to benefit students working on environmental projects and not only on this particular
project.
One of the objectives of this project is to train environmental engineering students at the
UV and provide them with hands-on experience, this objective has been achieved and it is a goal
from now on to continue training new students and teach them how to combine the type of
information gathered in a project like this and use data management tools like GIS.
6.1 Continuity of the Project and Improvements
The project has been active for at least 18 months to this day and it is expected to
continue for as long and it is needed to monitor the water quality in the rivers comprising the
area of study. Also, having water quality monitoring equipment will benefit environmental
engineering students during their learning process at school since many of them will work on
similar environmental projects during their careers.
As mentioned earlier, financial constraints were a concern to give continuity to this
project, year and a half after having started it still is a concern; however, the positive response of
students, who so far have been volunteers, and the positive response of professors who have been
willing to work off the clock with the students, has shown school officials that it is worth
investing in projects like this one.
40
During my last visit in October 2011 I was informed that the school had recently
purchased two multiparameter probes more advanced than the ones we donated. These two new
probes will be used for this same project and for other environmental projects that the
engineering department may have students involved in. This is a remarkable achievement
considering that the school is run on a tight budget with state funds. Before we started this
project their environmental laboratory had some limited equipment and now they have the
equipment we donated plus two HI 9828 multiparameter probes by HANNA Instruments. These
new probes measure various water quality parameters and are easier to use and calibrate. They
have a cost of around $2,000.00 dollars which was absorbed by the school. Furthermore, the
school will send in the equipment we donated for maintenance so that it can be in optimum
conditions by the time they resume the field work
In addition to the equipment purchased by the school, Dr. Gustavo Davila, CIATEJ
researcher, donated additional laboratory equipment such as laboratory glass and plastic bottles
and containers, and calibration standards for the existing equipment. Dr. Davila has also been a
great support to the UV and during our last visit he had the students and professors analyze
samples to detect the content of heavy metals and coli forms which from now on are new water
quality parameters that will also be monitored; Dr. Davila also donated some equipment to the
UV to monitor these new parameters.
The achievements in this project show that it has been a successful project, and it also
shows that it created a very positive academic impact at the UV.

7 CONCLUSION
This project started in January 2010 with its first planning stage and the initial field trips
in March 2010. It started as part of the activities of the MESA 2010 program at BYU going
alongside a development of a larger GIS project conducted by CIATEJ, with time this project
evolved into an ongoing field monitoring project involving and training students at the UV who
benefit from the results produced as they may use them for further applications.
The objectives of this project were accomplished as we developed and implemented a
water quality monitoring plan for the Cazones River, Tuxpan River, and the Tecolutla River in
Veracruz, Mexico, and the data produced can be used as input data for a GIS that will be used as
a DSS at a watershed level for the area of study. We trained environmental engineering students
at the UV on monitoring water quality and applications of GIS, and also provided them with
hands-on experience. We produced water quality data of the rivers that comprise the area and it
can be used for future projects and research activities. And finally we created an ongoing
program conducted by students and faculty members at the UV to monitor water quality in water
bodies which made a highly positive academic impact.
This project gave me the opportunity to work on a real-life application of engineering that
will produce results even in the long run and thus it will continue making a positive impact. It
also gave me the opportunity to develop technical and leadership skills as I worked coordinating
activities both in the field and in the lab and also here at BYU and in Mexico at the UV.
