Littlestown, Pennsylvania’s
Home for Water Softeners,
Water Filters, and Water Delivery

Yes, Littlestown tap water is treated to meet drinking water standards. However, meeting those standards does not mean the water is free from everything homeowners may want to reduce. However, the report detected contaminants including nitrate, PFAS, arsenic, uranium, radium, chlorine, lead, copper, and disinfection byproducts. Many homeowners choose drinking water filtration or reverse osmosis to add another layer of protection for the water they drink and cook with every day.

Littlestown’s water supply comes from multiple groundwater wells located throughout the borough, including wells near South Queen Street, St. Johns, Briarwood, Heritage, Lumber Street, Meadowview, and Appler. Because groundwater can be influenced by nearby land use, natural minerals, agricultural activity, and environmental conditions, water quality can vary before treatment reaches customers’ homes.

Yes. The Pennsylvania Department of Environmental Protection completed a Source Water Assessment for Littlestown’s groundwater wells. The report states that the wells are potentially susceptible to contamination and that source water can be affected by activities occurring above and around the aquifer. Groundwater systems are often influenced by agricultural runoff, septic systems, industrial activities, and naturally occurring minerals.

Yes. A separate nitrate advisory was issued in April 2026 after elevated nitrate levels were detected in one well. Borough officials removed the affected well from service and the advisory was later lifted.

Yes. Littlestown reported PFOS at 14.3 ppt and PFOA at 4.75 ppt in their mst recent water quality report. PFAS are often called “forever chemicals” because they can persist in the environment for long periods. While the reported levels were below applicable standards at the time of testing, many homeowners choose reverse osmosis systems to help reduce PFAS in drinking water at the kitchen sink.

Yes. In April 2026, one borough well tested at 21.5 ppm, triggering a temporary drinking water advisory for infants under six months old. The affected well was removed from service and the warning was lifted after follow-up actions and testing. Because nitrate levels can fluctuate in groundwater systems, many homeowners prefer to monitor and reduce nitrate levels in drinking water, especially households with infants.

Yes. Littlestown reported arsenic at 1.0 ppb, below the federal drinking water standard of 10 ppb. Arsenic can occur naturally in groundwater as water moves through rock and soil formations. Although the reported level was below regulatory limits, some homeowners choose additional drinking water treatment for added peace of mind.

Littlestown did not list fluoride as a detected contaminant in Littlestown’s water supply. While fluoride is commonly monitored in many public water systems, no fluoride result was reported in the detected contaminants tables provided in the report.

Yes. Littlestown reported total trihalomethanes (TTHMs) at 21.5 ppb and haloacetic acids (HAA5s) at 10.9 ppb. These compounds can form when chlorine reacts with naturally occurring organic matter in source water. The reported levels were below federal limits, but many homeowners use activated carbon filtration to help reduce chlorine-related tastes, odors, and disinfection byproducts.

Chlorine is added to disinfect the water supply and help protect against harmful bacteria and other microorganisms as water moves through the distribution system. Littlestown reported chlorine levels ranging from 0.403 to 2.11 ppm. While chlorine plays an important role in water treatment, some homeowners choose filtration systems to reduce chlorine taste and odor.

The Consumer Confidence Report does not include a hardness measurement. Because Littlestown relies on groundwater wells, some homes may experience hard water caused by naturally occurring calcium and magnesium minerals. A local water test is the best way to determine your home’s hardness level. If hard water is present, a water softener can help reduce scale buildup, spotting, and other common hard water issues.

Littlestown reported a 90th percentile lead level of 2.0 ppb, below the EPA action level of 15 ppb. Lead typically enters drinking water through household plumbing materials rather than the water source itself. Because lead levels can vary from home to home depending on plumbing conditions, some homeowners choose certified drinking water filtration systems for additional protection.

Littlestown reported a 90th percentile copper level of 0.173 ppm, below the EPA action level of 1.3 ppm. Copper commonly enters water through household plumbing and fixtures. While the reported level met drinking water standards, testing can help determine whether plumbing-related metals are present in water at an individual home.
