Arsenic in drinking water is a widespread concern. But, arsenic levels tend to be higher in groundwater sources, such as wells, than from surface sources, such as lakes or reservoirs. Arsenic in water has no color, taste or odor, even when present at elevated levels. Therefore, the only way to determine the arsenic level in your well water is by testing. Private wells in New Hampshire have about a 25% probability of containing naturally occurring arsenic above 5 micrograms per liter LEARN MORE
Minimal exposure to disease-causing organisms (bacteria, viruses, pathogens) in drinking water can cause immediate illness. Consuming small doses of microbiological contaminants in the coliform group of bacteria, such as E. coli and fecal coliform, has the potential to cause an immediate health risk; therefore, these are known as acute contaminants. Testing water for total coliform bacteria reliably predicts the absence or presence of many types of coliform bacteria LEARN MORE.
The range of hardness concentration in water is commonly referenced to its tendency to cause scaling on pipes and plumbing fixtures.
Hardness in drinking water is comprised by natural minerals calcium (Ca) and magnesium (Mg), and is expressed as calcium carbonate (CaCO3) milligrams per liter (mg/L) or Grains per Gallon (gpg). These minerals are dissolved naturally by the groundwater interaction with soil and rocks such as limestone, calcite and some volcanic basalts.
Iron and manganese in your drinking water can affect the taste, but also leave rust stains on porcelain or corroded pipes.
Iron is known for the orange and brown stains which are caused when ferrous iron is exposed to oxygen. These unsightly stains can be seen in toilets, bathtubs, showers, sinks, dishwashers, and washing machines. Manganese leaves a brownish-black stain on laundry, plumbing, and fixtures.
Iron and manganese occur naturally in the earth’s crust and are released into water by weathering processes. Both elements are very common in both shallow and deep wells in New Hampshire. Concentrations in groundwater vary widely depending on the local geology and groundwater chemistry, from barely detectable levels of 0.05 mg/L or less to greater than 1.0 mg/L manganese or greater than 10 mg/L iron. Depending on localized pH and oxygen levels in the aquifer, these constituents may be found in t
Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic (PFOS) acid are part of a group of chemicals commonly referred to as perfluoroalkyl substances (PFASs) or perfluorinated compounds (PFCs). PFOA and PFOS are man-made chemicals that up until 2000 had been widely used in the manufacturing of many industrial and consumer products such as paper and cardboard food packaging, insecticides, electronics, stain repellants, paints, plumbing tape, firefighting foam and non-stick cooking surfaces.
Studies have shown that chronic or repeated ingestion of water with certain PFAS over a person’s lifetime may be associated with increased cholesterol and liver enzyme levels, as well as disorders of the cardiovascular, immunological, developmental and reproductive systems. Some scientific evidence suggests that certain PFAS, such as PFOA, may increase the risk of kidney and testicular cancer. According to the CDC’s Agency for Toxic Substances and Disease Registry (ATSDR), skin contact with PFAS
Radium emits energy in the form of alpha particles and gamma rays, and will also decay to form radon. Radium in drinking water is of primary concern because this radiation may cause cancer, kidney damage, and birth defects. Additionally, the decay of radium into radon presents another contaminant of health concern in drinking water as well as in the air. The National Academy of Sciences reported that exposure to radon in the air is the second cause of lung cancer next to cigarette smoking. In t
RADON OCCURRENCE IN A HOME Radon is a naturally-occurring radioactive gas that is commonly found in bedrock and in water from bedrock (drilled) wells in New Hampshire. Radon gas is colorless, odorless and tasteless. Radon gas finds its way into indoor air mainly by migrating from bedrock, through the soil and into the home via cracks or other openings in the foundation. Radon from bedrock wells is released into indoor air during showering, dishwashing and doing laundry.
The taste and odor of water is subjective; not all that use the water taste and smell the same thing. The cause of taste and odor issues can be from water fixtures, plumbing materials, water heaters, water treatment, pressure tanks and/or the source (the well). Determining the characteristics (ex. is both the hot and cold water affected, is it experienced at all sinks) and the potential cause of the taste or odor are important in identifying the best remedy to obtain a more desirable taste and o
A radioactive metallic element found naturally only in combination with other substances. Uranium 238 (U-238) is the most common form, but about 0.7 percent of natural uranium is present as U-235, which is the important fissionable component in work with atomic energy. Uranium in natural water exists as anionic complexes UO2(CO3)22- and UO2(CO3)34-.
Volatile organic compounds (VOCs) occur statewide in groundwater, but a number of activities and land uses seem to be associated with a higher likelihood of contamination. These include nearby fuel spills or leaks and businesses that use petroleum products or petroleum-based chemicals. ost VOCs enter the water supply directly as a result of human activity. Improper disposal of volatile organic compounds causes them to leach into the ground. Once they’ve infiltrated the groundwater, they can mig
