Exeter Water Quality Report: Contaminants & Treatment Guide

Written by Craig "The Water Guy" Phillips

Did you know that Exeter, New Hampshire residents are exposed to 11 different contaminants every time they turn on the tap?

Recent testing by the Exeter Water Department, which serves approximately 16,000 residents, revealed alarming water quality issues that affect daily life throughout this historic Seacoast community. With an Overall Water Score of C+, families living near the historic Exeter Academy, downtown Water Street, or the Squamscott River neighborhoods face documented exposure to multiple chemicals that exceed health advocacy guidelines.

While Exeter's water technically meets EPA legal minimums, earning an A grade for legal compliance, the concerning B grade for health guidelines tells a different story. Eight contaminants surpass levels recommended by independent health organizations, including the dangerous arsenic, cancer-causing disinfection byproducts, and radioactive elements.

The water, sourced from groundwater wells and treated by the Exeter Water Department, flows through aging infrastructure that contributes to contamination concerns. Every morning when families wake up in neighborhoods like Exeter Village or near Hampton Falls Road, they're unknowingly exposed to these documented contaminants through drinking, cooking, bathing, and even brushing their teeth.

Understanding Exeter's Water Hardness Crisis

Exeter's water hardness measures at a concerning level that creates daily problems throughout homes across the community. The Total Dissolved Solids (TDS) in your water supply means every gallon flowing through your home contains dissolved rock minerals that wreak havoc on plumbing, appliances, and your family's skin and hair.

This hardness exists due to Exeter's geological foundation. The Seacoast region sits atop granite bedrock and glacial deposits that naturally contain calcium and magnesium-rich minerals. As groundwater moves through these formations, it dissolves these minerals, creating the hard water that damages homes throughout the area. The deeper wells used by the Exeter Water Department tap into aquifers that have had extended contact with these mineral-rich formations, resulting in elevated hardness levels.

The visible impact appears throughout your home daily. In bathrooms, thick soap scum builds up on shower doors within days, white crusty deposits form around faucets and showerheads, and water pressure decreases as mineral buildup clogs fixtures. Your skin feels dry and itchy after showers, hair becomes dull and brittle, razor blades dull faster, and stubborn toilet bowl rings form despite regular cleaning.

Kitchen problems include cloudy spots on dishes and glassware even after washing, mineral buildup in coffee makers requiring frequent descaling, reduced dishwasher efficiency, and a filmy residue on cookware. Throughout your home, the water heater loses 29% efficiency due to scale buildup, washing machines struggle with dingy whites and stiff towels, you need 35% extra detergent for basic cleaning, pipes gradually clog with deposits, energy bills increase, and appliances require frequent repairs.

The financial devastation adds up quickly. Water heater replacements cost $1,200 every 6-8 years instead of 12-15 years with soft water. Extra detergent and cleaning products cost $180 annually. Increased energy bills from the 29% heating penalty run $150-300 yearly. Appliance repairs and replacements add $400-800 per year. Plumbing repairs demand $200-500 annually.

Total annual hard water damage: $1,130-1,980 every single year. Over 10 years, that's $11,300-19,800 in preventable costs. A SoftPro water treatment system pays for itself in just 2-4 years, then generates pure savings forever.

Comprehensive Contaminant Analysis: What's Really in Exeter's Water

Exeter's water testing revealed 11 different contaminants, with 8 exceeding health advocacy guidelines, tested by the Exeter Water Department serving 16,000 residents throughout the greater Exeter area. While none exceed EPA legal limits, the gap between "legal" and "safe" puts families at risk daily.

The most concerning detection is arsenic, a known human carcinogen that accumulates in body tissues over time. Even at levels below EPA legal limits, long-term exposure increases risks of bladder, lung, and skin cancer, plus cardiovascular disease. New Hampshire's granite bedrock naturally contains arsenic, making it a regional concern throughout the Seacoast area.

Multiple disinfection byproducts appear above health guidelines, including bromodichloromethane, chloroform, dibromochloromethane, and total trihalomethanes (TTHMs). These dangerous chemicals form when chlorine disinfectant reacts with organic matter in the water supply. The International Agency for Research on Cancer classifies several of these as probable human carcinogens, with studies linking long-term exposure to bladder and colon cancer.

Dichloroacetic acid and trichloroacetic acid, both haloacetic acids, exceed health advocacy guidelines and pose additional cancer risks. These chemicals persist in treated water and accumulate in the body through daily exposure.

Perhaps most alarming, radium combined (-226 & -228) appears above recommended levels. These are radioactive elements naturally occurring in New Hampshire's groundwater that cause kidney damage and increase cancer risk through cumulative exposure. The granite formations throughout the region contain naturally occurring radioactive materials that leach into groundwater supplies.

Additional contaminants detected include chromium (total), hexachlorocyclopentadiene, and dichloroacetonitrile. While currently below health guidelines, these chemicals contribute to the overall toxic load your family faces daily.

The Shocking Truth About Skin Absorption

Here's what most Exeter families don't realize: drinking contaminated water is only part of the problem. According to a landmark study published in the American Journal of Public Health (Volume 74, No. 5), the human body absorbs up to 64% of contaminants present in water through the skin during a typical 10-minute shower. The research, conducted by Dr. Halina Brown at the University of Pittsburgh, found that exposure to chemicals through bathing and showering can equal or exceed exposure through drinking.

Your family drinks 8 glasses of water daily—but soaks in 40+ gallons during showers and baths. Children's thinner, more permeable skin absorbs chemicals up to 40% faster than adults. Hot shower steam opens pores and airways, maximizing chemical absorption from Exeter's documented contaminants.

Every 10-minute shower equals drinking 2 liters of the same water in terms of chemical exposure to arsenic, TTHMs, and radioactive radium. When teenagers take 15-20 minute showers, they're absorbing these cancer-causing chemicals directly through their skin during critical development years.

The chlorine used for disinfection creates additional dangers in hot showers, releasing chlorine gas that enters lungs directly—far more dangerous than drinking the same water. This explains why many Exeter residents experience respiratory irritation, dry skin, and brittle hair without understanding the connection to their water supply.

Why Your Refrigerator Filter Isn't Protecting Your Family

Most Exeter families believe their refrigerator filter or Brita pitcher protects them from the documented contaminants in their water supply. This false security creates a dangerous illusion while exposure continues daily.

The reality is stark: refrigerator filters and water pitchers protect only 1% of your household water used for drinking and cooking. They don't filter the 99% used for showering, bathing, handwashing, teeth brushing, and dishwashing. Your family continues bathing in water containing arsenic, radioactive radium, and cancer-causing TTHMs.

Children absorb these chemicals through their skin during every bath and shower. The 64% skin absorption rate from the American Journal of Public Health research means your 6-year-old daughter absorbs more contamination during a 10-minute bath than drinking 8 glasses of filtered water.

Point-of-use filters create false security while danger continues. Every hand washing, tooth brushing session, and shower exposes your family to Exeter's documented chemical contamination. The most vulnerable family members—pregnant women, infants, elderly, and immunocompromised individuals—face the greatest risks from this ongoing exposure.

Cocktail effects matter too. While EPA tests individual chemicals, multiple contaminants interact unpredictably in the body. Exeter's combination of arsenic, disinfection byproducts, and radioactive elements creates cumulative health risks that no point-of-use filter addresses.

Real Exeter Families, Real Results

Sarah M., a mother of two living near Exeter High School, discovered her family's water problems when her 8-year-old son's eczema wouldn't respond to treatment. "The pediatric dermatologist asked about our water quality, which I'd never considered," she recalls. After researching Exeter's water testing results and finding the multiple contaminants above health guidelines, she contacted SoftPro's water quality expert Jeremy.

"Jeremy explained how the chloroform and other disinfection byproducts in our water were likely aggravating my son's skin condition through daily baths and showers," Sarah explains. She installed the Complete Home Protection Package, combining the SoftPro Elite HE Water Softener with the Alkalizing RO System.

Within two weeks, her son's skin irritation began improving. After two months, his eczema cleared completely for the first time in three years. "The whole family noticed softer skin and hair, but seeing my son comfortable in his own skin again was priceless," Sarah says. "Knowing we're no longer exposing him to arsenic and radioactive elements during critical development years gives me peace of mind I didn't know I was missing."

Mike R., a homeowner on Court Street, contacted SoftPro after his third dishwasher repair in two years. "Heather helped me understand that Exeter's hard water was destroying my appliances and costing me thousands annually," he explains. After installing the SoftPro Elite HE system, his energy bills dropped immediately, his water heater efficiency improved, and appliance problems ended.

"One year later, I've saved over $800 in energy costs alone, plus no more appliance repairs or replacement parts," Mike reports. "The system paid for itself faster than promised, and now I'm saving money every month while protecting my home's value."

Essential Questions Exeter Residents Ask

Is Exeter's water really that bad? It looks clear and tastes okay...

This is the most dangerous misconception because clear water does NOT equal clean or safe water. Testing found 11 contaminants with 8 exceeding health guidelines, plus problematic hardness levels. Many contaminants like arsenic, TTHMs, and radioactive radium are completely colorless, odorless, and tasteless yet accumulate in body tissues over years causing cancer, neurological damage, and organ failure. The Exeter Water Department provides water meeting EPA legal minimums, but "legal" doesn't always mean "safe" since EPA standards haven't been updated for many chemicals in decades while independent health organizations recommend much stricter limits based on current research.

I have a refrigerator water filter. Isn't that enough protection?

This is the most common and most dangerous false security trap. Refrigerator filters protect only 0.5-1% of household water used for drinking only. They do NOT filter water for showering and bathing (40-50 gallons per person daily), handwashing (20+ times daily), teeth brushing (direct mucous membrane exposure), cooking where pasta and vegetables absorb water, dishwashing leaving residue on plates, or laundry where fabric touches skin 24/7. The American Journal of Public Health research proves your body absorbs up to 64% of contaminants through skin during a 10-minute shower—more exposure than drinking 8 glasses of the same water. Every shower exposes your family to Exeter's arsenic, radioactive radium, and disinfection byproducts, with children facing greatest risk due to thinner, more permeable skin.

How much does a water treatment system cost, and what's the real return on investment?

This is the smartest question residents ask, and the answer often surprises people. The hidden costs of untreated water in Exeter include water heater replacement costs, appliance repairs and replacements, extra detergent and cleaning products ($180-250/year), increased energy costs from the 29% heating penalty ($150-300/year), plumbing repairs and fixture replacements, totaling $1,480-2,750 annually. Over 10 years, doing nothing costs $14,800-27,500 in damages and expenses while a SoftPro system investment pays for itself in 2-4 years then provides pure savings forever, creating net savings of $10,000-22,000+ over 10 years. Don't forget priceless intangible value: peace of mind about family health and safety, protection during children's critical development years, prevention of irreversible damage from arsenic and radioactive elements, quality of life improvements, and home value increases.
