EPA Monitoring U. S. Environmental Protection Agency l July of 1970, White House and Congress worked together to establish the EPA in response to the growing public demand for cleaner water, air and land. l The EPA was assigned the daunting task of repairing the damage already done to the natural environment and to establish new criteria to guide Americans in making a cleaner environment a reality.

EPA Monitoring U. S. Environmental Protection Agency Timeline: l 1970 s - EPA is created l 1980 s - The Superfund law is passed to clean up old, abandonded waste sites. l 1990 s - The Clean Air Act Amendments set the stage for further protections, such as dust and soot. l 2000 s - Mercury emissions, visibility rules further improve air quality. EPA responds to 9/11. Clean diesel engines cut emissions from trucks, offroad equipment, and especially school buses. l

EPA Monitoring and Assessing Water Quality WHO MONITORS? l Monitored by state, federal, and local agencies, universities, dischargers, and volunteers. l

EPA Monitoring and Assessing Water Quality l Nation´s streams, lakes, and coastal waters? On whether these waters are safe enough to swim in, fish from, or use for drinking? Monitoring provides this basic information. Ways to monitor water conditions: ~~> Monitoring specialists sample the chemical condition of water, sediments, and fish tissue to determine levels of key constituents such as dissolved oxygen, nutrients, metals, oils, and pesticides l

EPA Monitoring and Assessing Water Quality l Water quality data are used: 1. Characterize waters l 2. Identify trends over time l 3. Identify emerging problems l 4. Determine whether pollution control programs are working, such as floods and spills. l 5. Help direct pollution control efforts to where they are most needed l 6. Respond to emergencies l

Environment monitoring Laboratory: l What is water quality? l What is water-quality monitoring? Water quality is the chemical, physical, and biological condition of water, usually in respect to its suitability for a certain use. Water-quality monitoring consists of a variety of techniques that are used to assess the condition of streams, rivers, estuaries, and coastal waters. This process analyzes the suitability of water for certain purposes, such as drinking, swimming, fishing, and irrigation.

Dissolved Oxygen: Dissolved oxygen levels are affected by: -water temperature - when temperature decreases, more oxygen dissolves in water; when temperature increases, dissolved oxygen decreases -water discharge - when water discharge (flow) increases, dissolved oxygen increases -organic waste (such as leaves, sewage, industrial waste, agricultural/fertilizer runoff, and fecal matter) build up - when it increases, dissolved oxygen decreases l

Dissolved Oxygen: l Why is dissolved oxygen important to a healthy aquatic environment? -A high percentage of dissolved oxygen is conducive to supporting aquatic flora and fauna, such as algae, plants, fish, mollusks, and invertebrates. A low percentage or depleted of dissolved oxygen indicates a negative impact on a body of water, which results in an abundance of worms and fly larvae.

PH: l What affects p. H in stream water: -Acid rain influences water quality by lowering the p. H level in a body of water. Auto emission released in the environment converts to nitric and sulfuric acid in the atmosphere. The acid combines with water and falls to the earth as acid rain. -Non-point pollution, such as urban runoff (such as fertilizer, grass clippings, pet waste from streets and sidewalks, and paper litter). l How does this affect aquatic life? -The shift in p. H negatively affects plants and aquatic life by forcing the organisms to live beyond their optimal p. H range.

Some of the common probes usage include: Temperature - This is the most popular item. You can monitor the temperature for the datacenter as a whole, or can place a sensor on a particular rack. They are also useful for locations such as server closets where it is unlikely anyone will be around to notice a rise in temperature. Humidity - If the humidity is too high, it leads to corrosion. Too low and you have problems with excess static electricity. Water - Water on the floor, whether from a broken pipe or a leaky roof, can cause electrical shorts.
