Test your drinking water on a regular basis.

It is important to test your private well or spring for contaminants on a regular basis to make sure that it is safe to drink. If you are on public water, the Health Department recommends testing for lead. Learn about testing recommendations for public water

Recommended Private Drinking Water Testing Schedule

The Health Department recommends testing your water for bacteria, inorganic chemicals and gross alpha radiation. See the table below for more information on these drinking water contaminants.

The three test kits are called the Vermont Homeowner Testing Package:

  • Bacteria (Kit A) $14 – test every year
  • Inorganic chemicals (Kit C) $100 – test every five years
  • Gross alpha radiation (Kit RA) $45 – test every five years

If you divide this cost over the course of 5 years, it would equal $3.60 per month.

You can also order a test for an individual contaminant, such as lead. Find out more about testing options at the Health Department Laboratory

When to Test

Why You Should Test

Possible Cause(s)

Coliform Bacteria
(Kit A)
Every yearStomachaches, diarrhea, GI (gastrointestinal) diseasesSurface water intrusion, septic leachate, agriculture runoff
Arsenic
(Kit C)
Every five yearsIncreases risk of bladder, lung or skin cancerNaturally occurring in some bedrock and soils in Vermont
Chloride
(Kit C)
Every five yearsChloride may indicate other contaminants are present in the waterSeptic leachate, road salt
Copper (flush)
(Kit C)
Every five yearsStomachaches, vomiting, diarrhea, liver damage in young childrenLeaches from plumbing and fixtures due to corrosive water
Fluoride
(Kit C)
Every five yearsFluoride levels above 4 mg/L can cause bone disease. Fluoride levels above 2 mg/L can cause staining or pitting of teeth. Optimal fluoride levels of 0.7 mg/L prevent tooth decay.Naturally occurring in some bedrock and soils in Vermont
Hardness

Every five yearsCauses scale buildup in pipes and fixtures, gray staining of washed clothesNaturally occurring in some bedrock and soils in Vermont
Iron
(Kit C)
Every five yearsUnpleasant odors, stains and tastesNaturally occurring in some bedrock and soils in Vermont
Lead (first draw and flush)
(Kit C)
Every five yearsDamage to brain, kidneys and nervous systemLeaches from plumbing and fixtures due to corrosive water
Manganese
(Kit C)
Every five yearsDamage to the nervous system (memory, attention and motor skills) when consumed over a long period of time, infants may develop learning and behavior problemsNaturally occurring in some bedrock and soils in Vermont
Nitrate/Nitrite
(Kit C)
Every five years. If present above 5 mg/L: Every 3-6 monthsMethemoglobinemia (blue baby syndrome) in infantsFertilized agricultural fields, septic leachate, compost piles
Sodium
(Kit C)
Every five yearsSodium may indicate other contaminants are present in the water, can be harmful to those on limited sodium dietsSeptic leachate, road salt, water softeners
Gross Alpha Radiation
(Kit RA)
Every five yearsCancer riskNaturally occurring in some bedrock and soils in Vermont
Uranium
(Kit C)
Every five yearsKidney damageNaturally occurring in some bedrock and soils in Vermont

How to test

Why You Should Test

Possible Cause(s)

Hydrogen Sulfide 
(rotten egg smell)
Isolate the source of the smellGas in the air can be hazardous at high levels, can indicate sewage or other pollution intrusion in drinking waterNaturally occurring in some soil and rock as a byproduct of decay, produced by sulfur bacteria in the water system, water pollution (in rare cases)
PFAS
(including PFOA)
Private labs can test for PFASChild development, infertility, increased cancer risk, and interference with hormones, the immune system and cholesterol levelsChemicals used in industry and commercial products
RadonVermont Dept of Health Lab
Kit RC
(Learn more about testing for radon in air)
Stomach cancer, lung cancerNaturally occurring in some bedrock and soils in Vermont
Organic Chemicals
(volatile, synthetic, pesticides)

Kit OL or Kit OA
Cancer, cardiovascular problems, reproductive issues, liver problemsChemicals from human activities including agriculture, chemical spills, manufacturing sites
