EPA Monitoring U.S. Environmental Protection
Agency

• 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.
• 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.

• Timeline
• 1970s - EPA is created
• 1980s - The Superfund law is passed to clean up
  old, abandonded waste sites.

• 1990s - The Clean Air Act Amendments set the
  stage for further protections, such as dust and
  soot.
• 2000s - Mercury emissions, visibility rules
  further improve air quality. EPA responds to
  9/11. Clean diesel engines cut emissions from
  trucks, off-road equipment, and especially school
  buses.

EPA Monitoring Monitoring and Assessing Water
Quality

• WHO MONITORS?
• Monitored by state, federal, and local agencies,
  universities, dischargers, and volunteers.

EPA Monitoring Monitoring and Assessing Water
Quality

• Nations 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
• gt 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

EPA Monitoring Monitoring and Assessing Water
Quality

• Water quality data are used
• 1.Characterize waters
• 2. Identify trends over time
• 3. Identify emerging problems
• 4. Determine whether pollution control programs
  are working, such as floods and spills.

• 5. Help direct pollution control efforts to where
  they are most needed
• 6. Respond to emergencies

Environment monitoring Laboratory

• What is water quality? Water quality is the
  chemical, physical, and biological condition of
  water, usually in respect to its suitability for
  a certain use.
• What is water-quality monitoring? 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

Dissolved Oxygen

• 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.

9
PH

• What affects pH in stream water -Acid rain
  influences water quality by lowering the pH 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).
• How does this affect aquatic life? -The shift in
  pH negatively affects plants and aquatic life by
  forcing the organisms to live beyond their
  optimal pH 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.
