The document summarizes a study of the water quality of Froggy Bottoms wetland. Water samples were taken from three locations in the wetland over five weeks and tested for temperature, pH, conductivity, and dissolved oxygen. The results showed that locations two and three met standards for healthy wetlands, but location one sometimes did not meet standards due to being the wetland's inflow location. Overall, the study found the wetland has healthy water quality and functions as a sustainable ecosystem.
The study compared water quality parameters of greywater samples collected before and after treatment from four systems in Monteverde, Costa Rica. While water quality did not significantly differ before and after treatment within systems, some parameters differed between systems after treatment. Specifically, samples from the Monteverde Institute system had significantly higher conductivity, total dissolved solids, and salinity than other systems, possibly due to sediment and stagnant water. Samples from the Monteverde Country Lodge system had significantly higher nitrate nitrogen, likely due to its treatment of both greywater and blackwater. The study found treatment systems can improve some greywater quality aspects but their effectiveness depends on system design and water sources.
This document discusses various methods for sampling water. It begins by explaining that sampling must account for environmental heterogeneity and can involve static or dynamic systems. It then outlines five main sampling methods: systematic, random, judgmental, stratified, and haphazard. For each method, it provides an example of how it would be implemented for water sampling. It also discusses types of samples, equipment for surface and groundwater sampling, and considerations for continuous monitoring. The key points are that sampling must address spatial and temporal variability and that different methods have advantages for different sampling needs and environments.
1. Water sampling is the process of taking water samples for analysis to check water quality.
2. There are two main types of water sampling: grab sampling, which collects discrete samples at a point in time, and composite sampling, which mixes multiple grab samples.
3. The water sampling procedure involves identifying sampling points, collecting samples using proper containers and labels, and transporting samples to a laboratory for testing of various physical, chemical, and bacteriological parameters.
Vintage Water to the Costumers POSTER No 18 NDWC 2016Ole Silkjaer
The document summarizes research conducted by TREFOR Water in Denmark on the age, biostability, and taste of their groundwater sources. Age dating analysis found that water ages ranged widely from 34 to 358 years old. Testing showed that older water had greater biostability, taking longer for bacteria levels to increase tenfold. Blind taste tests also found that most participants preferred the taste of older vintage waters over younger ones. The research was aimed at understanding aquifer protection and water quality over long transport times in distribution systems.
The document discusses the importance of testing well water for total coliform bacteria and E. coli, which can indicate contamination and pose health risks if consumed. It provides instructions for properly collecting and submitting water samples to be tested at the certified Brazos County Health Department laboratory. The results indicate whether bacteria are present, and if positive, the water should be disinfected by adding bleach and flushing all faucets before retesting. Additional resources for water testing and treatment are also listed.
Experimental analysis of dew drain waterIRJET Journal
This document summarizes an experimental analysis of dew drain water. The author built dew traps of different sizes to collect condensed water from the inside of clear plastic coverings. Over 7 days, about 2 liters of water was collected and tested for various quality parameters including pH, hardness, turbidity, dissolved solids, acidity, alkalinity, chlorides, sulfates, dissolved oxygen, and biochemical oxygen demand. The results of these tests were then compared to drinking water standards, finding the dew drain water met all requirements after purification treatments. Collecting dew drain water was concluded to be an effective way to overcome environmental water issues and scarcity concerns, especially as these problems are expected to worsen in the

ASSESSMENTS
· Lab report (75): This is your first lab report of the semester – make sure you read the resources on writing a lab report and use the rubric – you can link to those here.
INTRODUCTION
PreviousNext
Water is a chemical (H2O) that all life depends on. It makes up about 60% of the human body and our cells and organ systems are dependent on its unique characteristics. It is an important solvent, which means that many things dissolve into it (see below for a short list). For example, table salt easily dissolves in water. Also, water naturally has a pH of 7, but when other chemicals are present the pH can change. When pH decreases, we call that acidic.
As human population grow, so do their needs for, including their need for water. Many researchers believe that in the next 20 years over half the world’s population will have a shortage of potable or drinkable water. Despite the fact that 75% of the surface of earth is covered in water, 97% is salt water in the oceans and another 2% is frozen in glaciers, leaving us with less than 1% to use. Scientists hope to develop methods to increase potable water using desalination techniques, but in the meantime we have to take care not to contaminate or pollute our current drinkable water sources.
Toxins in the water are absorbed or consumed by primary producers and primary consumers – those “low”on the food chain – like bacteria, algae, protists and invertebrates. As toxins are transferred “up the food chain” or from one trophic level to the next, they are concentrated and become even more toxic to the organism. This phenomenon is called bioaccumulation or biologic magnification (Figure 1). This is one reason that humans need to be concerned about pollution in natural rivers and lakes in addition to our public drinking water.

The document analyzes the effect of fertilization and environmental factors on water quality in the Upper Cove River Watershed. It tests variables like nitrate, temperature, dissolved oxygen, pH, and conductivity at various sites over time. The hypothesis is that nitrate levels will be higher in the east tributary flowing from a golf course and water quality will improve after passing through marsh areas. Testing found nitrate was higher in the east tributary and decreased after flowing through wetlands, while dissolved oxygen was higher in the west tributary. pH was lowest in late October and highest in early January.

A field experiment was conducted to determine the impact of low pH on the survival and settlement of dreissenid mussels. Water from Lake Ontario containing mussel larvae was pumped to a laboratory and divided into streams, with three streams having their pH adjusted to 7.3, 7.1, and 6.9 using phosphoric acid. The fourth stream served as a control. Adult mussels and settlement substrates were placed in tanks receiving each pH level or the control water. After 10 weeks, adult mortality reached 40% at pH 6.9. Adult mussels were significantly lighter at all pH levels compared to controls, indicating shell erosion and calcium loss. New settlement was essentially prevented at pH 7.1. The results suggest lowering pH

Drinking water quality
Figure 1: At any given moment, 97% of the planet’s water is in oceans. Only a small fraction of
the remaining freshwater is usable by humans, underscoring the importance of treating our wa-
ter supply with care.
It is no secret that water is one of the most valuable resources on Earth. Every plant and animal requires wa-
ter to survive, not only for drinking, but also for food production, shelter creation, and many other necessities.
Water has also played a major role in transforming the earth’s surface into the varied topography we see to-
day.
While more than 70% of our planet is covered in water, only a small percentage of this water is usable fresh-
water. The other 99% of water is composed primarily of salt water, with a small percentage being composed
23
of glaciers. Due to the high costs involved in transforming salt water into freshwater, the earth’s population
survives off the less than 1% of freshwater available. Humans obtain freshwater from either surface water or
groundwater.
Surface water is the water that collects on the ground as a result of precipitation. The water that does not
evaporate back into the atmosphere or infiltrate into the ground is typically collected in rivers, lakes, reser-
voirs, and other bodies of water, making it easily accessible.
Groundwater, on the other hand, is located underneath the ground. This water is stored in pores, fractures,
and other spaces within the soil and rock underneath the surface. Precipitation, along with snowmelt, infil-
trates through the ground and accumulates in available underground spaces.
Aquifers are areas in which water collects in sand, gravel, or permeable rock from which it can be extracted
for usable freshwater. The depth of aquifers varies from less than 50 feet to over 1,500 feet below the sur-
face. The water within an aquifer typically does not flow through, as it would through a river or stream, but in-
stead soaks into the underground material, similar to a sponge. As aquifers are depleted by human use, they
are also recharged from precipitation seeping into the ground and restoring the water level. However, many
times the recharge of the aquifers does not equal the amount of water that has been extracted. If that cycle
continues, the aquifer will eventually dry up and will no longer be a viable source of groundwater.

The document discusses parameters for analyzing waste water. It defines waste water as any water affected by human activity, including domestic, commercial, industrial and agricultural sources. Sewage is a type of waste water that often contains feces, urine and laundry waste. Key waste water parameters discussed include biochemical oxygen demand (BOD), chemical oxygen demand (COD), and dissolved oxygen (DO). Dissolved oxygen is important for aquatic life to breathe and is affected by temperature, organic waste levels, and other factors. Methods for sampling, storing, and analyzing BOD, COD and DO in the field and laboratory are also outlined.
This document summarizes an experiment that tested two methods for purifying water using solar disinfection. The researchers tested whether adding black tape (to accelerate heating) or aeration (to allow more oxygen absorption) was more effective at killing E. coli bacteria within 6 hours. They found that both the black tape and aeration methods reduced E. coli levels to under 100 in undiluted water and under 40 in a 1/10 dilution, demonstrating that solar disinfection through EPA Method 1604 can successfully purify water within a short time frame.

Final Lab Report
You are required to write a complete laboratory report that covers all three experiments for "Lab 2: Water Quality and Contamination," using knowledge gained throughout the course. To begin, download the Final Lab Report Template and utilize this form to ensure proper formatting and inclusion of all required material. Additionally, view the Sample Final Lab Report before beginning this assignment, which will illustrate what a Final Lab Report should look like. You must use at least four scholarly sources and your lab manual to support your points. The report must be six to ten pages in length (excluding the title and reference pages) and formatted according to APA style. For information regarding APA samples and tutorials, visit the Ashford Writing Center, located within the Learning Resources tab on the left navigation toolbar.
The Final Lab Report must contain the following eight sections in this order:
1. Title Page – This page must include the title of your report, your name, course name, instructor, and date submitted.
2. Abstract – This section should provide a brief summary of the methods, results, and conclusions. It should allow the reader to see what was done, how it was done, and the results. It should not exceed 200 words and should be the last part written (although it should still appear right after the title page).
3. Introduction – This section should include background information on water quality and an overview of why the experiment was conducted. It should first contain background information of similar studies previously conducted. This is accomplished by citing existing literature from similar experiments. Secondly, it should provide an objective or a reason why the experiment is being done. Why do we want to know the answer to the question we are asking? Finally, it should end with all three hypotheses from your Week Two experiments. These hypotheses should not be adjusted to reflect the “right” answer.

A STUDY ON THE IMPACT OF POLLUTION IN BELLANDUR LAKE DUE TO URBANIZATIONAmartya Jha
This document summarizes a study on the impact of pollution on Bellandur Lake in Bangalore due to urbanization. Water quality tests were conducted at 3 sites around the lake and showed high levels of pollution. A water quality index analysis classified the water quality as 'bad' at all sites. Additionally, a socio-economic survey found that local residents were concerned about the severe water contamination and its impacts on their health and livelihoods. In conclusion, urbanization has degraded the lake ecosystem through increased pollution and depletion of flora and fauna.
The students created a water purifier to address water scarcity and conservation. Their purifier uses activated charcoal, polyfil, and alum stone to mechanically and chemically filter water from a washing machine. It can purify 2-3 loads of washing machine water, raising the pH from acidic to a level suitable for plants but not human consumption. The project aims to educate about water conservation and reduce water waste.

Froggy bottoms write up-final
1. The Water Quality of Froggy Bottoms
Ewan Shortess, Honors Science
June 20, 2012
Abstract
The objective was to find out if the water quality of Froggy Bottoms was sufficient to
make Froggy Bottoms a sustainable healthy wetland. Background information suggested
that the various data points had to be within a specific range to be deemed healthy. Three
different locations at the wetland were picked, and each location was tested for dissolved
oxygen, pH, conductivity, and temperature four times in the course of five weeks. The
results showed that both locations two and three met established standards for water
quality (“5.9 Conductivity”, “Dissolved Oxygen”, “Recommended pH action level”), but
location one did not completely meet standards. However, it was adequate because
location one is the inflow location and one would expect it to have a lower water quality.
Big Idea
Water quality is a system of rating the quality of a particular water source. It is especially
important in the wild, where it impacts the surrounding environment.
Background Information
The wetlands of the San Juan valley go back a long time in their interaction with humans.
At one point, it was possible to canoe from one end of the valley to the other. Native
S’Klallam tribal members did this to avoid Point Wilson’s treacherous waters. After
settlement, the San Juan valley was used primarily as farm land. Froggy Bottoms was
used for farmland, but then became a horse pasture. A seasonal pond would gather about
half way in between the present day Cedar and Tremont Streets, covering the Milo Street
right of way. Major filling had been done on the north end of the property. In 1997, the
City of Port Townsend acquired the property, partly for storm water and wastewater
purposes. The property was not in very good shape. The previous owner, who was a city
employee, had requested that the city dump old gravel to fill the north end. Dump trucks
and bulldozers had roamed the site. The city installed a sewer line along the south side of
the property. However, the one large reason for acquisition was storm water run off from
San Juan Ave. The city redid San Juan Ave. at the time, imposing even a more pressing
need for storm water control. The San Juan valley is filled with many seasonal wetlands.
The city categorized the various wetlands, naming Froggy Bottoms “Wetland 6-1”. The
city hired a consulting firm to carry out a redesign of the wetland. The final result was a
conventional wetland that dealt with storm water effectively. The north bank was
excavated and dumped where the current pond was, shifting the pond north. The location
of the pond right now is on impermeable glacial till, so that the water table does not go
down, but does have an outlet at a certain rate. It does dry up in the summer, however.
Storm water from four storm sewer grates drains into a small settling pond before
entering the wetland. It was designed to keep sediment and other contaminants out of the
wetland as much as possible. Native plants and shrubs were also planted at the wetland.
2. Some of the invasive species in the wetland before restoration included poison hemlock,
himalayan blackberries, and orchard grass. Some new plants that were planted include
nootka rose, curly dock, bluegrass, creeping buttercup, and tall fescue. This is the first
field study done on Wetland 6-1 that is known.
There are many benefits and functions of wetlands. Wetlands develop plant food and
shellfish, along with regular fish for sustaining wildlife and economic development.
Wetlands also provide a good recreational area for bird watchers and people who like to
photograph or watch nature. Wetlands are especially important because they control
water quality. They can prevent pollution or sediment from going into streams or rivers
by letting it settle out. Wetlands are essential to wildlife. They provide habitat to many
species, like frogs, that can thrive in wetlands. Wetlands also help control floods by
taking some of the extra water from swollen creeks and rivers and diverting it into the
brackish wetland or backwater areas.
A healthy wetland should have plants and animals using it, and should not have any
significant pollution in it. However, here are some data ranges that may be helpful in
determining if Wetland 6-1 is a healthy wetland. The pH should be between 6 and 9,
according to the Massachusetts Department of Environmental Protection. Dissolved
oxygen should range from about 4-11 mg/L, with 7-11 mg/L being very good for streams
with fish. Four-7 mg/L is ample enough for ponds. The United States Environmental
Protection Agency states that most healthy lakes in the United States have a conductivity
level between 150 and 500.
Research Question
Does Wetland 6-1 have similar ranges of pH, conductivity, and dissolved oxygen as the
healthy levels portrayed in the background information?
Experimental Design
There are three locations in this experiment. Location one was picked because it is the
inflow of the water to the pond, plus it seemed like an area that would give interesting
results. Location two is close to location one, but in the main pond. It was a good area to
test because it is in brackish water, which is probably the most susceptible part of a
wetland to contamination. Location three is across the pond from the other locations, and
was necessary to get an overall picture of the pond. See the Map for the exact locations.
3. The four things that were tested were temperature, conductivity, pH, and dissolved
oxygen. Dissolved oxygen, conductivity, and pH probes need to be rinsed with distilled
water before and after use. It is also necessary to calibrate the dissolved oxygen probe on
site. Use film containers to hold about 100 ml of distilled water. That way, each probe
will have a before and after container that can be used. First take the temperature probe,
the conductivity probe, and the pH probe and put them in a plastic tub. Also put in the
tub a rag and the necessary film containers with distilled water. Have a Vernier LabQ or
similar interface unit with you at all times. With these materials, go to all the locations in
order. Record the start time using the clock on the interface unit. First, take the
temperature, and then record it. While measuring data with any of these probes, one
should make sure not to record the data until the reading stabilizes. Then, take the
conductivity probe and rinse it in distilled water. Then record the conductivity. Put the
conductivity meter on the setting of 0-200, because pond water has low conductivity
compared to some waters. After one takes the conductivity measurement, rinse the probe
in distilled water, and then wipe it dry with a clean rag. For the pH sensor, unscrew the
bottle with pH base four solution in it, and then take the probe out of the bottle, leaving
the lid attached. Then remove the lid from the probe. Rinse the pH sensor in distilled
water. Measure the pH and record it. Then rinse the sensor in distilled water, and
carefully wipe it with the rag. Place it back in the bottle with the pH base four.
4. However, only screw on the lid about half way. Then place the probe into the bottle and
push it in so that it is fully immersed in the base four solution. Fully screw on the lid.
Then repeat all the testing steps, from the recording of the time to screwing on the lid of
the pH sensor at locations two and three as well. After that, one needs to calibrate the
dissolved oxygen probe. In order to do this, follow the directions on the instruction sheet
that came with the probe. First, add 1 ml of DO-electrode filling solution that comes with
the probe. Warm up the dissolved oxygen probe for ten minutes in one of the film
containers of water, while connected to the interface. While waiting, take the air
temperature by plugging the temperature sensor into another port. Then enter the
calibration program on the interface, which is accessed through the menus at the top.
Click on calibrate, and then “Calibrate DO Probe”. Then place the DO probe in the
Sodium Sulfate solution that came with the probe for about 10 seconds. Enter 0 as the
first value in the calibration routine. Then squeeze the bottle of Sodium Sulfate solution
so that there is no air inside. The solution will keep longer this way. Then rinse the
probe in distilled water and place it in the provided calibration bottle, and slide the lid
about ½ inch onto the probe body. Add about ¼ inch of water to the bottom of the bottle
and screw on the cap. When the reading stabilizes, enter the correct value based on the
air temperature and the barometric pressure. Then go around to all the testing sites,
measuring, and recording the data. Carry the probe around in one of the film containers
of distilled water, but blot the probe dry before and after running all of the tests. Make
sure the probes are cleaned and stored correctly, and dump out all contaminated distilled
water.

As one might expect, temperature increased steadily during the study. The pH was also
pretty constant during the study. The conductivity leveled off or decreased. Dissolved
oxygen decreased initially, but then went up again. Dissolved oxygen and temperature
do seem have a correlation, but I also think that dissolved oxygen and rainfall seem to
have a more direct relationship.
8. Conclusions
Froggy Bottoms has the characteristics of a healthy functioning wetland. Based on the
background information, most of the data meets the requirements of a healthy wetland.
For pH, all of the data values, except location one, are above six, which meets the criteria
stated in the background information. Location one’s unusual data stems from the fact
that location one drains San Juan Ave., so it would be more susceptible to contamination,
and therefore acidity. The conductivity levels also are acceptable, as applied to the
background information. However, again location one has levels that do not meet the
conductivity standards of the US EPA. This is probably because there is a noticeable
inflow from the storm sewer into the location one area, and because the water is moving,
there is less time for solids to sink. Dissolved oxygen of the wetland meets the standards
of 4-11 mg/L. Locations three and one had the lowest dissolved oxygen at 4.0 mg/L.
However, locations two and one both had dissolved oxygen values above 7 mg/L, which
is considered enough to support fish in a small stream. Therefore, locations two and
three are good functioning wetland areas in terms of water quality. They both have data
that suggests that those parts of the wetland are healthy. Location one is a little different.
Location one does not have enough dissolved solids in it to be deemed healthy by the
standards. In addition, the pH only rose over six once during my study. However,
because location one is the settling pond for this wetland, it is expected that the data is
not going to be as high as in other sections of the wetland. Because of this, wetland 6-1is
a healthy, functioning wetland.
Limitations
There are quite a few things that could be limitations in this experiment. The largest one
is that data was only taken for about two months in the year. Also, testing was not
performed everyday. Another limitation is that pH, temperature, conductivity, and
dissolved oxygen were the only tests run.
Next Focus Research Question
Does Wetland 6-1 contain fecal coliform?
