24 INFLUENCES ON DRINKING WATER QUALITY - 1 THE WATER SOURCE  Nitrates  Iron and Manganese  Pesticides  Odour or Taste (Algae)  Hardness  Pathogens - Cryptosporidium, Viruses, Bacteria

25 INFLUENCES ON DRINKING WATER QUALITY - 2 THE WATER TREATMENT PLANT  Fluoride  Aluminium  Odour or Taste (Chlorination)  THM’s (Chlorination Byproducts)

26 INFLUENCES ON DRINKING WATER QUALITY - 3 THE DISTRIBUTION SYSTEM  Discolouration (Sediment)  Odour or Taste (Chlorination)  Lead  Bugs / Creepy Crawlys

27 INFLUENCES ON DRINKING WATER QUALITY - 4 THE HOUSE PLUMBING SYSTEM  Lead Copper

28 DRINKING WATER QUALITY ISSUES - 1 MICROBIOLOGICAL CONTAMINATION  Loss of Chlorine Residual  Contaminated Source HIGH IRON AND MANGANESE LEVELS  Natural geological ground conditions HIGH NITRATE LEVELS  High applications of fertilizers, slurries etc.

29 DRINKING WATER QUALITY ISSUES - 2 NATURALLY OCCURRING URANIUM  Natural geological ground conditions - granite bedrock with high radon FLUORIDE EXCEEDENCES  Faulty dosing equipment DISCOLOURED WATER  Inadequate scouring  Bursts
