Common Water Contaminants in Virginia, Maryland & Pennsylvania

Water Quality Issues in Local Wells & Municipal Water

Maryland, Pennsylvania, and Virginia water issues can include the presence of natural or chemical substances in water. Contamination can affect both municipal and well water systems. Some of the most common water contaminants in drinking water stem from natural sources, while others come from pollution. Some sources include agricultural runoff, landfills, industrial pollution, and septic systems.

Many issues are easily fixed with water treatment systems. Some contaminants, such as radon or PFAS, may require specialty filtration.

Detect Virginia, Pennsylvania & Maryland Water Issues

Trusting your drinking water is essential. There are certain contaminants that easily go undetected, but there are many indicators that can point to a problem. Our water treatment specialists can help pinpoint the type of contamination affecting your water supply.

Hard Water

Hard water is one of the most common water issues in Maryland, Virginia, and Pennsylvania. It contains high levels of calcium and magnesium.

Excess minerals can leave spots on dishes, dry out skin, and cause scale buildup in pipes and appliances. Soap may not lather well, and laundry may feel stiff. Hard water can also lower the efficiency of water heaters and other appliances.

A water softener is the most common and best solution for hard water. It removes minerals before they enter your plumbing system. This helps protect pipes, fixtures, appliances, and clothing.

Acidic (Low pH) Water

Acidic water is common in some well water systems. Water with a low pH can slowly damage pipes, fixtures, and even appliances. Signs may include blue-green stains, metallic-tasting water, or pinhole leaks in copper pipes.

Acid neutralizers and chemical feed systems can fix acidic water. These systems help raise the pH level and reduce corrosion. Water testing can identify the problem early.

High Iron Levels

Iron is one of the most common water contaminants in private wells. It can leave red, orange, or brown stains on sinks, tubs, toilets, and laundry. Iron may also cause metallic-tasting water. Some homes have iron bacteria, as well, which can create slimy buildup and bad odors in pipes and fixtures.

Iron filtration systems remove excess iron from water. Treatment may also include sediment filters, oxidation systems, or chemical treatment for iron bacteria. Water testing can help determine the best solution.

Nitrates

Nitrates are a common water contaminant in rural parts of Maryland, Virginia, and Pennsylvania. Fertilizer runoff, septic systems, and farm waste are common causes. Nitrates usually do not change the taste, smell, or color of water, so annual testing is important.

High nitrate levels can be harmful, especially for infants and young children. Reverse osmosis systems and specialty filtration systems can help reduce nitrates in drinking water.

Bacteria

Bacteria can enter private wells through flooding, heavy rain, well damage, or septic system problems. Signs may include cloudy water, bad odors, or unexplained stomach illness. However, in many cases, bacteria cannot be seen, smelled, or tasted.

Laboratory testing is the best way to check for bacteria in your water. Treatment may include UV water treatment, chlorination, water filtration installation, and/or well repairs.

Chloramines in Municipal Water

Many municipal water systems use chloramines to disinfect drinking water. As a result, some homeowners notice a chemical taste or odor. Chloramines may also cause dry skin or irritation after bathing.

Activated carbon filters and reverse osmosis systems can help reduce chloramines in drinking water. Whole-house water filters can also improve water taste and odor throughout the home.

PFAS Contamination

PFAS are often called “forever chemicals.” They have become a growing water quality concern across the country. PFAS can enter groundwater from industrial sites, firefighting foam, and contaminated runoff.

PFAS cannot be seen, smelled, or tasted in water. Specialized water testing is often needed to identify them. Reverse osmosis and activated carbon filters are common treatment options for reducing PFAS in drinking water.

Taste & Odor Issues

Taste and odor problems are common in both well water and municipal water. Water may smell metallic, earthy, musty, or like chemicals. Some well water contains hydrogen sulfide gas, which causes a strong rotten egg smell.

Treatment depends on the source of the problem. Solutions may include carbon filters, aeration systems, chemical treatment, or water softeners. Water testing can help identify the cause and recommend the right treatment system.

How Frequently Should I Test My Water?

The Environmental Protection Agency (EPA) recommends testing your well water once a year. This is especially important if you’ve installed a new well or have replaced or fixed pipes, pumps, or the well casing. Other circumstances may also prompt you to test immediately:

  • Someone in your household is pregnant
  • There is a newborn or young child in your home
  • Household members are experiencing unexplained health problems
  • You have experienced changes in water taste, smell, color, or clarity
  • A chemical or fuel spill occurred near your water supply
  • Your neighbor had a septic tank issue that caused waste contamination in the soil
  • Your public water supply was contaminated or not properly disinfected
