Timelapse – Google Earth Engine. Water Quality Monitoring: Total Phosphate. Total Phosphate Phosphorus is usually present in natural water as phosphates (orthophospates, polyphosphates, and organically bound phosphates). Phosphorus is a plant nutrient needed for growth and a fundamental element in the metabolic reactions of plants and animals (hence its use in fertilizers).
Sources of phosphorus include human and animal wastes (i.e., sewage), industrial wastes, soil erosion, and fertilizers. Excess phosphorus causes extensive algal growth called "blooms," which are a classic symptom of cultural eutrophication and lead to decreased oxygen levels in creek water. Test Equipment Hach Total Phosphate Test Kit (Cat. Procedure If turbidity is low (less than 5 jtu), it is possible to skip the total phosphate measurement and proceed directly to orthophosphate, since very little phosphate will be attached to suspended solids in the water. Total Phosphate Put on gloves and goggles.
Orthophosphate Fill the square mixing bottle to the 20 ml mark with the water to be tested. Phosphate. Phosphate Phosphates enter lakes, ponds, rivers, estuaries, and the ocean from various primary sources such as inorganic fertilizers, wastewater treatment from municipal sources, runoff from feed lots, soaps and detergents, and industrial processes. Certain types of detergents can introduce a high concentration of phosphate ions into bodies of water. In detergents, tripolyphosphates are used to stabilize dirt particles and complex Ca2+ and Mg2+ to prevent combining with the detergent molecule resulting in superior cleaning ability. However, when the soluble detergents are rinsed away, the resulting wash water has high concentrations of phosphates which act as environmental "nutrients. " Orthophosphates and condensed phosphates are highly soluble in water.
The orthophosphate ion (PO43-) has the P atom centrally located, bonded to oxygen atoms which are located at the corners of a tetrahedron (yes, you should be able to draw this.) Phosphate in Water. Phosphate in Water Details Written by Mr. Brian Oram, PG Total Phosphorus and Phosphate Impact on Surface Waters The Drinking Water Helpguide - Free Information on Water Quality and the Environment Information on Water Testing EPA Onsite Wastewater Treatment: Systems Management Advanced Stormwater Treatment: Nutrient Removal Phosphate Cycle Phosphates PO4-3 are formed from this element. Orthophosphate forms are produced by natural processes, but major man-influenced sources include: partially treated and untreated sewage, runoff from agricultural sites, and application of some lawn fertilizers.
Phosphate rock in commercially available form is called apatite and the phosphate is also present in fossilized bone or bird droppings called guano. Small amounts of certain condensed phosphates are added to some water supplies during treatment to prevent corrosion and this chemical is used extensively in the treatment of boiler waters. Why Phosphorus Is Important Environmental Impact: Blue-Green Algae. Climate hockey stick graph. Mann. Mann's hockey stick wrong? Francis hockeystick01.html, version 1.1, 31Oct2003 The hockey-stick graph of the Mann, Bradley and Hughes calculation of past temperature was the master-piece evidence to declare that global warming is unprecedented during the last years compared to the temperature profile of the preceeding centuries (see: Mann, Bradley, Hughes (1998): Global-Scale Temperature Patterns and Climate Forcing Over the Past Six Centuries, Nature, No. 392, pp. 779-787, 1998).
Here is the original hockey stick graph with a comment from co2andclimate (see: Now it seems that the graph is based on faulty and/or incomplete data; a recalculation using Mann's own methodology has been made by independent (not sponsored nor funded!) This paper is a possible fatal blow to one of the IPCC's pillars in "documenting" global warming! Here the conclusion of the authors; Here a letter from Prof.

Public Summary of the June 2015 draft final “Lake Wingra Watershed Management Plan” Prepared by Jim Baumann – June 25, 2015 In 2009, the Friends of Lake Wingra (FoLW) published Lake Wingra: A Vision of the Future that stated four main goals for Lake Wingra: Clean, clear waterRestored spring flowAbundant native plants and animalsStewardship and enjoyment To achieve and sustain these goals, FoLW realized that management of the 3,500 acre urban Lake Wingra watershed was vital.
In June 2015, the 243-page draft final plan was released for public review and comment. Realizing that a person living in the watershed would find the length of the plan daunting and the format associated with state storm water permit difficult to understand, FoLW prepared this brief summary.

MILWAUKEE, Wis. — The goal of the game "Citizen Science" is to save Lake Mendota in Wisconsin from pollution. To save the day, players must do all of the usual video game stunts, like travel through time or talk to animals. "Citizen Science" is just one of many video games developed by Games + Learning + Society (GLS). GLS is a company that calls itself one of the longest standing games-for-learning research centers in the world. It is a key player in a growing field that brings scientists, educators and game designers together.
The goal of GLS is to change traditional science education methods using video games. The creators of these video games do not want to replace teachers and traditional education methods. "Citizen Science" To The Rescue Kurt Squire grew up playing and learning from video games. “I was personally struck by the fact that we have these lakes right in downtown Madison that you can’t really swim in,” he said.
