The Water Cops PR CL project involves students exploring their local watershed to understand water flow and how human activities impact water quality. Students collected water quality data from two sites on the Rio Piedras river using sensors to measure temperature, dissolved oxygen, turbidity, conductivity, pH and stream flow. Analysis showed normal readings except for higher than expected turbidity and conductivity at one site. A second site on the Guaralcanal stream had elevated levels of nitrates and ammonium, likely due to agricultural runoff polluting the water. Creating a watershed model with GIS software allowed for spatial analysis of the data and identification of population densities near sampling areas.
The Planet Guardians project measured water quality in the Sabana Llana stream. They used Vernier sensors to test parameters like temperature, pH, dissolved oxygen, conductivity, turbidity, and ion concentrations. Temperature, pH, and dissolved oxygen levels were within normal ranges for aquatic life. However, turbidity was high, and concentrations of ammonium, nitrates, and chlorides exceeded safe levels. This suggests the stream is polluted by contaminants like agricultural runoff and other discharges. While some physical characteristics were acceptable, the chemical analysis revealed pollution that could harm the stream's ecology if not addressed.
This document summarizes a study on the seasonality of contamination, toxicity, and quality values in sediments from coastal ecosystems in the Gulf of Cadiz in Spain. Sediment samples were collected from seven stations in winter and summer and analyzed for heavy metals, organic carbon, grain size, and toxicity. Toxicity tests using amphipods and clams showed only sediments near an untreated urban discharge were toxic. Multivariate analysis found most variables did not vary seasonally, except copper which was toxic in winter but not summer. Sediment quality values were derived from chemical concentrations associated with no biological effects.

This document is a dissertation submitted in partial fulfillment of a Bachelor's degree in environmental sciences. It presents the results of a study monitoring the phytoplankton communities in a eutrophic Irish lake over a 6-month period from January to July 2012. Phytoplankton assemblages were found to follow clear seasonal successional patterns related to changing water quality and nutrient conditions. Their composition supported the lake's status as healthy but bordering on mesotrophic/eutrophic. The study evaluated phytoplankton as biological indicators for monitoring water quality and ecological status under the EU Water Framework Directive.
Cold-water coral reefs located in deep marine environments between 40-3000 meters are at risk from ocean acidification and rising temperatures. These ecosystems support high biodiversity but are difficult to study due to their depth. Researchers use submersibles, ROVs, multibeam sonar and other acoustic sensors to map and model these areas, helping to understand environmental impacts and informing conservation efforts. New sensor technologies aim to improve monitoring of carbon chemistry critical to these habitats.
Natural radioactivity in drinking water and associated agedependent dose in L...IOSRJAP
The presence of Ra in drinking water may sometimes make important contribution to natural background radiation exposures. The paper describes the study of 226Ra and 228Ra content in drinking water of Luxor, a famous tourist city in Egypt. A total of thirty-five water samples were analyzed for 226Ra and 228Ra by gamma ray spectrometry with HPGe detector setup, coaxial type and 8192 channels MCA. The concentration of 226Ra was found in the range from 16 to 181 with arithmetic mean 85.6 mBq·L -1 and the concentration of 228Ra ranged from 8 to 98.4 mBq·L -1 with arithmetic mean 48.6 mBq·L -1 .The committed effective dose for the different age groups has been estimated and found to be not more than 0.038 mSv·yr -1 for adults and 0.149 mSv·yr -1 for critical age group (12-17 years old), for 226Ra. While it is not more than 0.05 mSv·yr -1 for adults and 0.29 mSv·yr -1 for critical age group, for 228Ra. The values obtained were compared with the reference values accepted for drinking water and doses resulting from consumption of these waters, due to their 226Ra and 228Ra contents, were calculated. The study showed that 226Ra content for investigated categories of waters is below the levels at which any unacceptable dose due to ingestion would arise

Analysis of physicochemical parameters of sewage water used for irrigation in...Alexander Decker
This document summarizes a study that analyzed physicochemical parameters of sewage water used for irrigation in Bauchi, Nigeria. Samples were collected from 6 sites along a drainage channel and tested for temperature, pH, electrical conductivity, hardness, alkalinity, nitrate-nitrogen and phosphate-phosphorus. The results from the study sites were generally within standards for irrigation water but nitrate-nitrogen and electrical conductivity exceeded limits at some sites, indicating higher pollution levels compared to the control site. The study concluded that sewage water supplies more nitrogen than required for crops and periodic monitoring is needed to prevent risks to soils and vegetables from irrigation with sewage water.

CHARACTERIZATION OF LEACHATE FROM MUNCIPAL LANDFILL AND ITS EFFECT ON SURROUN...Dr. Naveen BP
Percolating water passing through waste becomes contaminated and will have dissolved soluble organic and inorganic compounds as well as suspended particles. Also the pore fluid of the waste is often released and mixes with this water. The entire contaminated fluid is called leachate. There are many factors that affect leachate production like annual precipitation, runoff, infiltration, evaporation, transpiration, and freezing, mean ambient temperature, waste composition, waste density, initial moisture content, and depth of the waste fill. The production of leachate reduces when a landfill is closed. The decomposition of waste in presence of water can be separated into two different phases of degradation viz., initial aerobic and subsequent anaerobic. Generally, the leachate undergoes natural chemical changes over time that reduces its toxicity. Some of the soluble contaminants enrich the water table, or the saturated zone. Some of remaining molecules naturally adsorbed to the clay liner particles. The paper discusses the characteristics of leachate generated from municipal solid waste landfill and its effect on surrounding water bodies near Mavallipura landfill area in Bangalore. Two samples of water from the nearby pond and well were collected from downstream of Mavallipura landfill site. Physico-chemical characterization of leachate has shown that the leachate contains high concentrations of organic and inorganic constituents beyond the permissible limits. While the heavy metals concentration was in traces as the waste is dumped in the landfill is mainly domestic in nature. The pH of the leachate is marginally alkaline as the pH is 7.4. The results also showed that the highest metal concentration that exists in the leachate was Iron which is about of 11.16 ppm. BOD5 and COD of the leachate are 1500 mg/l and 10400 mg/l, respectively. The leachate characteristics indicate favorable growth of algae in natural water contaminated with leachate with the alkaline condition and with the presence of magnesium as nutrient, which has been confirmed in the nearby surface pond. Knowledge of leachate quality will be useful in planning and providing remedial measures to protect surface and ground water quality in the area.
This document summarizes a study that evaluated two water quality labs at the University of Arkansas to determine if there were significant differences in their measurement of nitrate concentrations in surface water samples. Standards with nitrate concentrations ranging from 0.01 to 10 mg/L NO3-N were tested in each lab to examine precision and accuracy. Environmental samples from streams and lakes across Arkansas were also tested to evaluate performance over a broad range of concentrations. The goal was to ensure the labs could accurately measure nitrate levels near thresholds important for algal growth in surface waters.

INFLUENCE OF LEACHATE MIGRATION ON GROUND WATER QUALITY Dr. Naveen BP
In this paper, the concept of leachate pollution index, a tool for quantifying the leachate pollution potential and water quality index for surrounding water bodies of Mavallipura landfill site in Bangalore has been applied. It has been found that the leachate generated from the Mavallipura landfill site has high contamination potential to the surrounding water bodies. The results revealed that quality of ground water resources in Mavallipura landfill is deteriorating largely, as a result of the poor practice of solid waste management. Hence, an effective remedial plan needs to be prepared for the sustainable water quality maintenance of the area.

The document summarizes a study that was conducted to determine sources of water pollution in Appiakrom community, Ghana. The study examined a dam, pond, and two boreholes used by the community. Laboratory analysis of water samples found that the dam, which supplies water to the district, had been polluted by anthropogenic activities. The rusty nature of one borehole was attributed to underground parent materials. The pond interfaced with the dam, and pollution could flow between the two sources. The authors recommend blocking channels between the pond and dam, and practicing zero-fertilizer farming near the dam to reduce pollution.
Paper 1 evaluates using machine learning to predict water quality parameters. It found ANN can predict parameters like alkalinity, chloride and sulfate with 83.94-87.9% accuracy.

Environmental Monitoring Model of Health, Parasitological, And Colorimetric C...theijes
The sanitary quality of water was evaluated in two micro basins, Bacaxá and Capivari belonging to the Lakes Basin St. John in the state of Rio de Janeiro, Brazil, for colimetric and parasitological analysis. Analyses were performed seasonally over a year and the levels of Escherichia coli were within the recommended only in the summer of 2012 and fall, and inappropriate with levels above recommended in winter, spring and summer of 2013 in both the micro basins. Through our observations, we compare the average values of the levels of total coliforms and Escherichia coli between both rivers. Initially, the samples indicate a similarity between the distributions of coliforms and Escherichia coli. However, Mann-Whitney-Wilcoxon test samples indicate that the distributions are different. In parasitological analysis it was observed that in Capivari was detected a greater presence of filarial larvae. Anthropogenic influences mainly by the presence of sewage is being able to compromise the health quality of the micro basins studied carrying a significant pollutant load to the Juturnaíba reservoir. The monitoring of the sanitary quality of the watersheds that supply the population may indicate when it is necessary to adopt more effective measures in the treatment of water supply of cities.

JBES| Water quality and socio-demographic assessment of Mahuganao Stream: inp...Innspub Net
Small as they may appear, headwater streams are very important because the health of the organism depends on that network of streams. The present study deals with the assessment of water quality of Mahuganao Stream, the socio-demographic and economic profile of residents living near the stream, the way they utilize the stream and how much waste they can produce. The analysis of the water samples collected was done in the laboratory to determine the Water Quality Index. Twelve (12) households were interviewed to elicit information on their socio-demographic and economic profile, how they utilize the stream and the amount of waste each household produces. Overall, Mahuganao stream is within the standard set by the agencies concerned such as DENR, PNSDW and USEPA. The socio-demographic profile of the community and its solid waste management is seen to be changing over time due to the fact that the median age at present is found to be within their late teens. There is a need to manage the stream as this group of people has the capacity to reproduce and could increase the anthropogenic activities and waste generation in the area.
Water quality can be assessed through various physical, chemical, and biological indicators. It depends on factors like geology, ecosystem, and human activities. Standards are set based on intended uses like drinking, industrial, or environmental. Water is sampled and tested using on-site or laboratory methods to monitor these indicators. Maintaining adequate water quality is important for public health and ecosystem protection.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Water Cops CL project is a multi-application where students have the oppor-
tunity to perform research on water quality from several points of Rio Pie-
dras. The students will be using technologies such as: Vernier Technology to
take water quality measurements. It will be chosen an urban water body close
to the school and two sampling locations will be selected in this body of water.
There will be three trials for each sample using the different sensors of
Vernier LabQuest. Some of the measurements which will be performed are:
-Turbidity
-Conductivity This measurements were took using :
-Alkalinity
Vernier Labquest Sensors
-pH
-Temperature
-Dissolved Oxygen
- Stream Flow

domestic use and water.
Turbidity is a measure of water’s lack of clarity. Water with high turbidity is cloudy, while
water with low turbidity is clear. The cloudiness is produced by light reflecting off of particles in
water; therefore, the more particles in the water, the higher the turbidity.
Stream flow or discharge is the volume of water that moves through a specific point in a
stream during a given period of time. Stream flow is an important factor in the stream ecosys-
tem and is responsible for many of the physical characteristics of a stream. Stream flow has two
components. The first is flow velocity, and the second is the volume of water in the stream.
The average of the stream flow was 0.18 cfs.
The conductivity of a substance defines as the ability or power of conducting heat, electricity.
Pure water is a good conductor of electricity. According to our results, the sample has medium
levels of conductivity. The normal conductivity level in a river or lake is of 5.5 μS/cm, however
our readings were of 381 μS/cm. The average of the conductivity was 381 μS/cm.

Discussion of the Results
According to the dynamic model created with the ArcGIS
Explorer can be seen clearly that the population density surround-
ing the sampling area is extremely high. Research tells us that most
of the parameters are expected and normal levels, but we have to
watch some of these which are the maximum allowed or are al-
ready at higher levels than expected.
With this model, students can create spatial analysis of data ac-
quired, organized and manipulated by them.
Students sampled two areas of Rio Piedras river: Jardín Botánico and Guaralcanal
stream. In the first site of the stream the samples showed normal levels of measurement,
except turbidity and conductivity that are in the maximum level of the accepted range. In
the second site the samples showed a level of nitrate and ammonium above the maximum
level of range accepted. This second point is the most affected by pollution which the
NH4 and NO3 levels are strongly affected, reflecting a level far above the expected level.
The possible causes are the agricultural runoff, some kind of human pollution entering the
water, animal feedlots, runoff from fertilized fields, or treated municipal wastewater being
returned to streams.
