Students manipulate a 3D aquifer model to illustrate porosity, permeability, and groundwater-surface water interactions. This makes it easier for a user to move from web page to web page and to complete commercial transactions over the Internet. The category of salts include compounds such as sodium chloride, magnesium sulfate, potassium nitrate, sodium bicarbonate, and others, all of which dissolve into ions. This Science Olympiad event is designed to increase middle school students' understanding of groundwater through inquiry and discovery. The official rules in the current Rules Manual take precedence. Our opinion section is open to all.

Science Olympiad is a nonprofit organization devoted to improving the quality of science education, increasing student interest in science and providing recognition for outstanding achievement in science education by both students and teachers. Urbanization can also cause problems with fecal coliform bacteria levels because plant and animal wastes can be washed away by a storm into sewers and contaminate water. Please keep this in mind when reading the page and if possible. You must also bring a salinometer as well to measure saline solutions between 0 and 10% salinity within a range of 1% at regionals and. It is likely that manatee populations would decline if these sites were removed. Fecal Coliform Fecal Coliform bacteria are living organism entering streams.
Water Quality
To test the turbidity of the water, people also use a Secchi Disk. Coal mine drainage can lead to iron sulfide mixing with water and forming sulfuric acid. The more light that reaches the detector, the more particles are in the water. Low concentrations of total solids can limit growth of aquatic organisms, while elevated levels can lead to accelerated eutrophication of the water system and increase the turbidity of the water. Typically, this section will be worth about 5% of the test. Turbidity can also shield bacteria from certain types of sterilization of water.

There are several ions that contribute to alkalinity, including bicarbonate, carbonate, hydroxide, and phosphate. A nephelometer includes a light source shining at a column of water and a detector surrounding the column to the sides. In some cases, microbes in an environment use oxygen faster than it can enter the water. Euhaline waters typical oceans are waters with a salinity between 30 and 35 ppt. These criteria are scientific assessments of the effects of turbidity, which are used by states to develop their own water quality standards.

If a stream or river has below 5 ppm of dissolved oxygen, then that can put aquatic life under stress, and below 1-2 ppm for a few hours can kill large fish living in the river. You can get good ideas on designs by watching any of them. These waters then enter a sedimentation basin or a settling basin that allow the floc to settle to the bottom of the tank. Alkalinity in aquatic ecosystems needs to be within a certain range, depending upon the ecosystem. Phosphates are often released from mining and can enter waterways through mine runoffs. Environments in which salinity varies over time are called poikilohaline. The presence of high levels of fecal coliform bacteria can be an indication of a failure in water treatment, a breach in the distribution system, or possible contamination.

Two very important factors are temperature and atmospheric pressure. The official rules in the current Rules Manual take precedence. Rules Clarifications You can submit specific questions about rules to the Science Olympiad organization. Nitrates do contribute to total dissolved solids and can be used as a water quality indicator.

The other 15% of the total salts are other salt ions such as Magnesium, Strontium etc. Other email that you may send to us may not be secure unless we advise you that security measures will be in place prior to your transmitting the information. The official rules in the current Rules Manual take precedence. Thermal pollution increases the sensitivity of organisms to disease, parasites, and pollution. For those who are interested, there is an available in the Science Olympiad Store. Salinity is an important water quality factor.

Alkalinity Alkalinity is the ability of a solution to neutralize an acid without changing the overall pH of the solution. It is a logarithmic scale, meaning that a given pH level has 10 times the concentration of hydrogen ions as the pH level that is one greater than the given. The official rules in the current Rules Manual take precedence. When measuring, this depth is usually reported in feet to the nearest tenth of a foot, or meters to the nearest tenth of a meter. Increases in the temperature of the water is called thermal pollution. As the wastewater moves through the soil, it is further treated by the natural processes of oxidation and filtering. Place a ball of clay on one end of the salinometer, completely covering the opening of the straw.
