BACTERIA IN WATER

Proper collection and handling of a water sample is critical for a meaningful water test. Sample containers have to be obtained from the testing laboratory because containers may be specially prepared for a specific contaminant.

Sampling and handling procedures will depend on the specific water quality concern and will be followed carefully. If the water is being treated, it will be necessary to sample both before and after the water goes through the treatment equipment.

When Should You Test Your Water?

Whether you have a public or private water supply. You should have your water tested if the following situations arise:

• If family members or house guests have recurrent symptoms of gastrointestinal illness: Test for coliform bacteria, nitrate and sulfate.
• If household plumbing contains lead pipes, fittings, or solder joints: Test for pH, corrosion index, lead, copper, cadmium and zinc.
• If you are buying a home and wish to assess the safety and quality of the existing water supply: Test for coliform bacteria, nitrate, lead, iron,hardness, pH, sulfate, total dissolved solids (TDS), corrosion index and other parameters depending on proximity to potential sources of contamination.
• If a water softener is needed to treat hard water: Test for Iron and manganese, which decrease the efficiency of exchange softeners, before purchase and installation.
• If you wish to monitor the efficiency and performance of home water treatment equipment: Test for the specific water problem being treated upon installation, at regular intervals after installation, and if water quality changes.
• If water stains plumbing fixtures and laundry: Test for iron, manganese and copper.
• If water has an objectionable taste or smell; Test for hydrogen sulfide, pH, corrosion index, copper, lead, iron, zinc, sodium, chloride and TDS.
• If water appears cloudy, frothy, or colored: Test for color, turbidity and detergents.
• If pipes or plumbing show signs of corrosion: Test for corrosion index, PS, lead, iron, manganese. copper and zinc.
• If water leaves scaly residues and soap scum, and decreases the cleaning action of soaps and detergents: Test for hardness.
• If water supply equipment (pump, chlorinators, etc.) wear: rapidly: Test for pH, corrosion index.
