General properties of your water

The following section describes general indicators of your overall water quality. These parameters may not directly impact your health but they will influence the chemical nature of metals and other potential contaminants in your water supply.

  • pH
    8.6
    BASIC

    A measure of how acidic or basic your water is. A low pH may impart a bitter metallic taste and cause corrosion. High pH water may cause a baking soda-like taste and leave deposits on your fixtures. Unlike most other parameters, pH properly measured on-site is more accurate than pH measured in the lab.

    LEARN MORE
  • Alkalinity
    117PPM
    normal

    Determined by the properties of minerals dissolved in your water. It's a measure of your water's capacity to resist changes to pH. Strongly alkaline water has an objectionable taste that resembles baking soda.

    LEARN MORE
  • TDS
    495PPM
    normal

    TDS is a measurement of all the Total Dissolved Solids we found in your water. Some contaminants raise your TDS, while others do not. Water containing high TDS will often smell bad and taste bitter, salty or metallic.

Pipe health summary

The following section describes key parameters influencing the health of your pipes and treatment hardware.

  • Iron
    Not Detected

    At moderate concentrations, iron will give water an unpleasant, metallic taste. Less than 1 PPM of iron may cause reddish-brown stains on your water fixtures and clothing.

    LEARN MORE
  • Calcium
    20.83PPM
    normal

    Calcium has its own taste receptors on your tongue. A high concentration can taste bitter or sour. Some people enjoy the flavor it imparts on their water, but too much of it contributes to hardness and can form scale in your pipes.

    LEARN MORE
  • Magnesium
    Not Detected

    While magnesium can make your water taste better, too much of it can contribute to hard water and form scale in your pipes.

    LEARN MORE
  • Manganese
    Not Detected

    Above 0.050 PPM you may notice a metallic taste, brownish-black or brownish-red color on toilets, shower curtains and sinks. Levels of manganese above 0.02 PPM may stain clothing.

    LEARN MORE
  • Grains per gallon
    3.45Grains
    Normal

    Elevated water hardness affects pipe maintenance, water taste, and the ability of your water to form soap bubbles (laundry, dish washing, showering etc).

    LEARN MORE
  • Hardness (Total)
    59.05PPM
    Normal

    Total hardness is the sum of all hardness-contributing metals and minerals in your water. Mostly representative of calcium and magnesium, total hardness also includes contributions by barium, copper, zinc, iron, strontium and more. Water hardness may cause scaling and bad tasting tap water. Hardness contributes to white film on glassware and can make soap bubbles difficult to form.

    LEARN MORE
  • Hardness (Ca, Mg)
    7.4PPM
    normal

    Mostly representative of the calcium and magnesium in your water. Hard water may cause your water to taste unpleasant and is known to leave residues on water fixtures, be harmful to your pipes and make it difficult to form bubbles when using soaps.

    LEARN MORE
  • Langelier Saturation Index
    0.64
    Some Faint Coating

    The Langelier Saturation Index is calculated based on your sample's chemistry and is assuming cold water. It's used as an indicator of the corrosive or scale forming potential of your water.

Likely sources of discoloration

Of the things that we detected in your sample, these are the ones most likely to be affecting your water's color.

  • Copper 1.956 PPM

    High copper concentrations can cause water to turn blue or green in color. Staining of fixtures generally begins around 1 PPM copper concentrations.

  • Turbidity 5 NTU

    Turbidity of 4 NTU and above may cause a milky-white, muddy, red-brown or black suspension in water.

What can improve my water?

Water temperature, general chemistry and other differences in human sensitivity will all impact how inorganic or organic contaminants alike affect drinking water smell, taste, and color. In general, cool water is more palatable than warm water. Higher water temperature increases chemical volatility and may also increase growth rates for microorganisms.

DETECTIONS FOR ANALYTES TESTED AS PRESENCE/ABSENCE ARE SHOWN HERE

E. coli Bacterial Pathogen
TESTED AND DETECTED
HEALTH EFFECTS

The presence of E.coli bacteria in your water is an indicator that one or many different harmful pathogens may be present in your water.

SOURCES

E.coli bacteria are the most common type of fecal coliform bacteria. E.coli live in the intestines of humans and other animals. Contamination of your drinking water by E. coli implies a the fecal waste is coming in contact with your water supply.

Total Coliform Bacterial Pathogen
TESTED AND DETECTED
HEALTH EFFECTS

The presence of coliform bacteria in your water is an indicator that one or many different harmful pathogens may be present in your water.

SOURCES

Coliform bacteria are bacteria that are commonly found in plants and soil but also live in the fecal waste of humans and other animals. Contamination by colifom bacteria means there is a possible fecal waste stream coming in contact with your water supply.

Other findings

THESE ARE THE CONTAMINANTS WE DETECTED BELOW POTENTIALLY DANGEROUS LEVELS.

  • Fluoride show less
    YOUR MEASUREMENT
    1.97 PPM
    HEALTH EFFECTS
    High levels of fluoride in drinking water (>4 PPM) can cause bone disease and dental fluorosis. Such concentrations are rarely reached in public water systems and much more likely in private well water. Increasingly, there has been some research into the health effects of lower concentrations of fluoride when consumed in drinking water. It's unclear whether low concentrations of fluoride have negative health effects.

    COMMON SOURCES
    Fluoride in drinking water is commonly added by public water systems as an additive to protect teeth. Natural fluoride is also eroded from soil and rock deposits, used as a fertilizer, and commonly in the wastewater of aluminum intensive industries. It's unclear whether low concentrations of fluoride (added to water by public water systems) have any dental benefits considering how little time tap water stays in contact with your teeth (compared to toothpaste).

    LEARN MORE
  • Phosphorous show less
    YOUR MEASUREMENT
    2.9 PPM
    HEALTH EFFECTS
    Phosphorous concentrations found in drinking water are not associated with any health effects.

    COMMON SOURCES
    Phosphorus is commonly found in groundwater concentrations near agriculturally active areas because it is a common ingredient in fertilizer. Public water systems will also commonly add phosphates to the drinking water as a corrosion inhibitor to prevent lead and copper from leaching into your water from pipes and fixtures.

    LEARN MORE
  • Sodium show less
    YOUR MEASUREMENT
    27 PPM
    HEALTH EFFECTS
    Sodium is important to your body for maintaining blood pressure, controlling fluid levels and keeping healthy nerve and muscle function. Sodium levels in drinking water are not normally a health concern (especially when compared to the sodium you consume from food) but it's important to always ask your doctor for such advice, especially if you're sensitive to high sodium levels.

    COMMON SOURCES
    Sodium is commonly detected and tasted in drinking water. Saline intrusion, mineral deposits, seawater spray, sewage effluents, and road salts used in de-icing can all contribute significantly to sodium levels in drinking water. In addition, water treatment chemicals and water softeners can increase sodium levels at the tap.

    TASTE & ODOR
    Sodium produces a salty taste in drinking water that can be detected (depending on someone's age) between 30 and 460 ppm.

    LEARN MORE
  • Total Dissolved Solids show less
    YOUR MEASUREMENT
    495 PPM
    HEALTH EFFECTS
    TDS is a general characteristic of water and does not itself have known health effects. However, the particulate materials that can cause high TDS may be harmful to human health.

    COMMON SOURCES
    As water travels over the land surface and through the ground, it dissolves naturally occurring minerals. TDS is a measure of all those dissolved particles in your water. It is a general characteristic of water rather than a specific chemical.

    TASTE & ODOR
    Water containing high TDS will often smell bad and taste bitter, salty or metallic

    LEARN MORE
  • Turbidity show less
    YOUR MEASUREMENT
    5 NTU
    A measure of the cloudiness of your water, or how much your water scatters light. Turbidity is caused by all the little particles and sediments that get into your water.
  • Conductivity show less
    YOUR MEASUREMENT
    241 umhos
    HEALTH EFFECTS
    Changes in conductivity likely indicate changes in your water quality, but there are no known human health impacts directly associated with the conductivity of your water.

    COMMON SOURCES
    Conductivity is a measure of your water's ability to conduct an electrical current. Though related to the mineral content in your water, it does not give an actual indication of which chemicals are present. If your water’s conductivity is substantially more than twice its hardness, then that may indicate the presence of other ions like nitrate or chloride.

    TASTE & ODOR
    Normally, conductivity is about twice the total hardness of your water.

    LEARN MORE
  • Selenium show less
    YOUR MEASUREMENT
    0.009 PPM
    HEALTH EFFECTS
    Hair or fingernail loss; numbness in fingers or toes; circulatory problems

    COMMON SOURCES
    Selenium is a naturally occuring metal in the soil and groundwater. It's deposits can also be due to human activity like mining, smelting, waste water discharge and coal/oil combustion.

    LEARN MORE
  • Strontium show less
    YOUR MEASUREMENT
    0.449 PPM
    HEALTH EFFECTS
    Ingestion of small amounts of strontium is not harmful. With long-term chronic exposure at concentrations above 4 PPM, strontium may affect bone growth and impact children. There is less evidence suggesting impact on adults. High concentrations of radioactive strontium isotope, strontium-90 may cause cancer.

    COMMON SOURCES
    Dust, soil, foods and drinking water all contain small amounts of strontium. Geologic weathering leads to naturally-occurring strontium in the environment. Strontium-90 occurrence may also be linked to nuclear fallout and other anthropogenic sources such as air contamination from milling processes, coal burning, and phosphate fertilizers. However, high levels of strontium can occur in water drawn from bedrock aquifers that are rich in strontium minerals.

    YOUR MEASUREMENT
    0.03 PPM
    Does not exceed any recommended thresholds. (MCL is 0.1)
    HEALTH EFFECTS
    Total chromium, as sampled in water and the environment, takes two principal forms: trivalent chromium (i.e. chromium III) and hexavalent chromium (i.e. chromium VI). Chromium VI is a potent human carcinogen according to the International Agency for Research on Cancers. It affects the human liver and kidney, and is known to cause circulatory disorders, as well as nerve damage. While chromium III is an essential human nutrient, excess of chromium III can cause illness and skin rash. However, it is not as severe a health concern as chromium VI.

    COMMON SOURCES
    The most common source of total chromium (and chromium VI) in drinking water is from the waste of nearby mining activity, electroplating and pigment factories. Chromium may also enter your water supply during erosion from natural deposits.

  • Alkalinity (as CaCO3) show more
    YOUR MEASUREMENT
    117 PPM
    Does not exceed any recommended thresholds.
    Determined by the properties of minerals dissolved in your water. It's a measure of your water's capacity to resist changes to pH. Strongly alkaline water has an objectionable taste that resembles baking soda.
  • Calcium show more
    YOUR MEASUREMENT
    20.83 PPM
    Does not exceed any recommended thresholds.
    HEALTH EFFECTS
    No significant health effects are associated with drinking calcium in your water. In fact, calcium is one of many minerals found naturally in water and essential to your health.

    COMMON SOURCES
    As water enters the atmosphere it gets enriched with carbon dioxide (and forms a compound called carbonic acid). Later in the water cycle, that same water seeps into the ground and comes into contact with calcium-rich stone. The carbonic-acid-water extracts calcium from the stone and carries it through your pipes to your tap.

    TASTE & ODOR
    Calcium has its own taste receptors on your tongue. A high concentration can taste bitter or sour. Some people enjoy the flavor it imparts on their water, but too much of it contributes to hardness and can form scale in your pipes.

    HEALTH EFFECTS
    Water hardness (measured at GPG or Hardness) is not a known human health concern in drinking water.

    COMMON SOURCES
    Calcium and magnesium ions are commonly present in drinking water in various forms (sulfates, chlorides, carbonates and bicarbonates) which cause water to be hard. Water chemists measure these impurities in parts per million (ppm) and then mathematically convert them to a common unit of hardness called, grains of hardness per gallon of water (gpg).

    TASTE & ODOR
    Elevated water hardness affects pipe maintenance, water taste, and the ability of your water to form soap bubbles (laundry, dish washing, showering etc).

    LEARN MORE
  • Hardness (Ca,Mg) show more
    YOUR MEASUREMENT
    52.01 PPM
    Does not exceed any recommended thresholds.
    HEALTH EFFECTS
    Hardness is mostly representative of the calcium and magnesium in your water, both are essential ions for your health and are not regulated as toxins by the US EPA. Hardness measuring from 0 - 60 PPM is considered "soft"; 60 - 120 PPM is considered "moderately hard"; above 120 is "hard".

    COMMON SOURCES
    Hardness is mostly a measure of the calcium and magnesium levels in your water. Calcium and magnesium typically dissolve into your water from soil and rock that are naturally occurring in the ground.

    TASTE & ODOR
    Hardness is mostly representative of the calcium and magnesium in your water, both are essential ions for your health and are not regulated as toxins by the US EPA. Water hardness may cause scaling and bad tasting tap water. Hardness contributes to white film on glassware and can make soap bubbles difficult to form.
  • Hardness (Total) show more
    YOUR MEASUREMENT
    59.05 PPM
    Does not exceed any recommended thresholds.
    HEALTH EFFECTS
    Total hardness is the sum of all hardness-contributing metals and minerals in your water. Mostly representative of calcium and magnesium, total hardness also includes contributions by barium, copper, zinc, iron, strontium and more. Total hardness is not toxic and not known to affect human health but some of the minor contributing metals that help comprise Total hardness may have health implications.

    COMMON SOURCES
    A minor contribution to the total hardness of water is made by the presence of other polyvalent ions like aluminum, copper, barium, iron, manganese, strontium, and zinc.

    TASTE & ODOR
    Total hardness is the sum of all hardness-contributing metals and minerals in your water. Mostly representative of calcium and magnesium, total hardness also includes contributions by barium, copper, zinc, iron, strontium and more. Water hardness may cause scaling and bad tasting tap water. Hardness contributes to white film on glassware and can make soap bubbles difficult to form.

  • Zinc show more
    YOUR MEASUREMENT
    2.24 PPM
    Does not exceed any recommended thresholds.
    HEALTH EFFECTS
    Zinc is an essential nutrient, however drinking water with high levels of zinc can lead to stomach cramps, nausea and vomiting.

    COMMON SOURCES
    Zinc may enter your drinking water supply from natural erosion of soil and other bedrock or from artificial pathways. Zinc is commonly found in the waste by-products of steel production, coal-fired power stations, and the burning of waste materials. Zinc is used in some fertilizers that may leach into groundwater. Older galvanized metal pipes and well cribbings may be coated with zinc that can be dissolved by soft, acidic waters over time.

    TASTE & ODOR
    Metallic Taste

  • Sulfate show more
    YOUR MEASUREMENT
    81 PPM
    Does not exceed any recommended thresholds.
    HEALTH EFFECTS
    High levels of sulfate (above 250 ppm) may have a laxative effect and cause dehydration, especially among infants.

    COMMON SOURCES
    Sulfate most often enters drinking water when it comes in contact with underground rock formations and waste streams from nearby industrial activity.

    TASTE & ODOR
    Water containing elevated sulfate will taste salty.

    LEARN MORE
  • Molybdenum show more
    YOUR MEASUREMENT
    7 PPM
    Does not exceed any recommended thresholds.
    HEALTH EFFECTS
    Not much is known about the long term health effects of molybdenum in drinking water, although there is some evidence very high exposure may result in higher serum uric acid levels and gout-like illness.

    COMMON SOURCES
    Molybdenum is a naturally-occurring metal found in small amounts in the bedrock. It is most commonly used in the production of steel and cast iron. It is also used for manufacturing electronic components, and pigments.

    LEARN MORE
  • Mercury show more
    YOUR MEASUREMENT
    0.0001 PPM
    Does not exceed any recommended thresholds.
    HEALTH EFFECTS
    Chronic mercury ingestion above the US EPA limit of 2 PPB can cause kidney damage. Methyl mercury in particular may be a dangerous neurotoxin, affecting vision, hearing and memory.

    COMMON SOURCES
    Primary sources of mercury in drinking water are coal-fired power plants, medical and municipal waste incinerators, metal and cement manufacturing, crop runoff, and erosion of natural deposits.

Understanding your Tap Score

First time reading a Tap Score Report? This section explains what all the bars and colors mean.

SimpleWater's health risks analysis compares your sample’s contaminant levels to the latest publicly available toxicological and epidemiological research. This is done in order to give you a clear idea of what potential risks may be in your water. Click on each contaminant to learn more about its known health impacts and potential sources. This analysis should not be taken as professional health advice.

  • GOOD - You're In The Clear
    If your result is to the left of the middle line it means we detected this contaminant but at a concentration that is not known to cause health problems for healthy adults.

  • ELEVATED - Approximate Risk Factor < 1 in 100,000
    Drinking water contaminated at this level is not immediately concerning but is worthwhile monitoring since concentrations may vary over time and there may be a small long term health risk.

  • MODERATE - Approximate Risk Factor > 1 in 100,000
    Drinking water contaminated at this level over several years is thought to pose a moderate health risk. If you drink this water frequently it's worth considering treatment.

  • HIGH - Approximate Risk Factor > 1 in 10,000
    Drinking water contaminated at this level over several years is thought to pose a significant health risk that should not be ignored. We do not recommend drinking this water without treatment.

  • VERY HIGH - Approximate Risk Factor > 1 in 1,000
    Drinking water water contaminated at this level is thought to pose a high risk to your health. If possible, other water sources should be used or appropriate water treatment should be installed.

  • What do diagonal lines mean?
    Simply, they mean that any concentration of this contaminant is potentially harmful.

  • You may want to consider these tests

    • Because your level of Chromium (Total) was 0.02 PPM or higher

      Total chromium is the sum of three forms of chromium. Chrome-0, chrome-3 and chrome-6. Hexavalent chromium (Chrome-6) is the most poisonous form of total chromium found in drinking water. Since you have high levels of total chromium in your water sample, you might want to do a followup test to figure out how much of your total chromium is hexavalent chromium. LEARN MORE

    • Because your level of Nitrate (as N) was 5 PPM or higher

      Nitrate in drinking water can make people very sick, especially infants. The most common sources of nitrate in water are agricultural runoff and septic leakage. You may want to test for other common runoff contaminants like pesticides and herbicides. LEARN MORE
