Water Quality Management 2012

  1. 1. POND & LAKEWATER QUALITY MANAGEMENT PRESENTATION 800.693.3144 www.aquamasterfountains.com
  2. 2. TODAY’S GOAL• Review factors that impact water quality. - Nutrients, Temperature, Oxygen• Examine associated problems. - Excessive algal & weed growth, fish kills, poor clarity, foul odors, insect infestation, sludge build-up.
  3. 3. TODAY’S GOAL CONT’D • Address problem management methods. - Mechanical Control - Chemical Control - Biological Control - Aeration
  4. 4. A Healthy Pond• Balanced Ecosystem• Problems Absent• Sufficient O2 Levels• Sufficient Aerobic Bacteria Levels• Fish and other Aquatic Wildlife Present
  5. 5. Healthy Ponds
  6. 6. Unhealthy Pond• Out of Balance• High Nutrient Levels• Aerobic Bacteria Cannot Keep Pace with Nutrient Loading• Algae, Weed Growth and Other Problems Appear
  7. 7. Severe Problems
  8. 8. Nutrients• Carbon Based Compounds Containing Phosphorous and Nitrogen• Phosphorous is the Greatest Contributor to Aquatic Plant Growth• Nutrients Come From Several Sources
  9. 9. Nutrient Sources• Bottom Sediment and Dead Organic Matter are the Primary Sources• Run-off and Inlet Water are Secondary• Nutrient Cycling Process Contributes - Eutrophication Occurs• Effluent (Treated Wastewater)• Fertilizer Leaching
  10. 10. Eutrophic PondsA eutrophic lake (derived from the Greek, eu meaning good / well and trophic meaning food / nutrients) is a lake with high primary productivity the result of high nutrient content
  11. 11. Hypereutrophic Ponds lakes are very nutrient-rich  
  12. 12. Temperature Factor• Thermal Stratification
  13. 13. Oxygen Factor• Stimulates Aerobic Digestion Process - Reduces Excess Nutrients• Supports Food Chain and Entire Ecosystem
  14. 14. How Oxygen Enters A Pond • Rainfall (Natures Aerator) • Atmospheric Contact and Wind • Photosynthesis by Aquatic Plants and Algae
  15. 15. Oxygen Depletion• Stress Occurs When Levels Drop Below 3 to 4 parts per million• Late Night or Just Before Dawn• Cloudy, Still Days• High Nutrient Content• After Chemical Application
  16. 16. Pond Depth Factor• Shallow Depths Allow Warming and Greater Sunlight Penetration• Increased Photozone Accelerates Plant Growth
  17. 17. How The Factors Interact • As pond ages, nutrient levels rise due to increase in bottom organic sediment, run-off and fertilizer use in surrounding watershed. Algal and aquatic weed growth increase. Algae and weeds die, sink to bottom to decompose. This biomass will increase the aerobic bacteria population, utilizing large amounts of oxygen to digest the organic waste.
  18. 18. How The Factors Interact • Due to thermal stratification, top and bottom layers will not mix. Oxygen cannot reach the bottom to support aerobic digestion. Oxygen depletion will occur and may cause nutrient cycling, fish kills, and foul odors caused by anaerobic digestion
  19. 19. How The Factors Interact • The water quality of this pond is now very poor. • Excessive nutrients, poor circulation and low oxygen levels. • Mosquito and other insect populations breeding in stagnant, algae covered surface water. • What Can Be Done To Remedy This?
  20. 20. Solutions • Mechanical - Dredging - Raking • Expensive • Treats symptoms, not causes • Temporary
  21. 21. Solutions - Chemical • Most popular • Quick • Specific plant elimination • Promotes nutrient cycling • Accelerates O2 depletion • Treats symptoms • Does not improve water quality
  22. 22. Solutions – Lake Dye • UV Blocker • Inhibits Photosynthesis • Aesthetic appeal
  23. 23. Solutions-Biological • Weed Eating Fish – Triploid Grass Carp • Create Wetlands to Absorb Nutrients Before They Can Enter Pond • Littoral Zone Plantings to Absorb Nutrients Before Entering Pond • Berms – Topological Relief to Prevent Run-off Nutrients from Entering Pond
  24. 24. Littoral Zone Plantings
  25. 25. Solutions - Biological • Bioaugmentation – Beneficial Bacteria or Enzymes • Benthic Zone (Pond Bottom) Weed Mats
  26. 26. Solutions - Aeration • Helps Keep Three Contributing Factors; Temperature, Nutrients and Oxygen in Balance • Has No Harmful Side Effects and Naturally Supports the Eco-System • Attacks the Source of the Problem; Poor Water Quality, thus Impeding Algal and Weed Growth, Bottom Sludge Build-Up, Odors and Insect Infestations
  27. 27. Aeration Tests• To Prove Positive Effects, Two Simple, Cost Effective Tests Can Be Performed• Perform a Before and After Test• Test in a True Stress Situation, After Dark or Before Dawn on a Hot, Cloudy Day at 3’ and 10’ of Depth• Use an O2 Monitor to Record DO Levels and Temperature to Test Mixing• Aerators Should Run For 72 Hours, Non-Stop, Before Testing
  28. 28. Aerator Types• Surface Spray• Bottom Air Diffusion• Mixers and Aspirators
  29. 29. Surface Spray• Provide DO and Vertical Circulation• Most Effective in Depths Less Than 12’• OTR Exceeding 2lbs per HP, per Hour• Supplemental Aesthetics
