Microbiological

COLIFORM BACTERIA (MCL=Detected) are groups of bacteria that indicate the possible presence of infectious disease organisms. It is recommended that water with coliform bacteria not be consumed until the problem is resolved. Coliform bacteria may get into the water supply through surface run-off, especially after heavy rainfall. Fecal coliform, when accompanied by high nitrate and sulfate levels, may indicate a septic system or other fecal polluting source. Coliform present at a public water supply user's faucet may be a result of water and sewage pipes being cross connected causing plumbing backflow.

Recommended Treatment: Chlorination, Ozonation or Ultraviolet Light.
