For more than 25 years, Dierolf Plumbing & Water Treatment has served as Merion Station’s local water quality experts. With over 1,000 five-star reviews, Licensed Master Plumbers, and Licensed Well Inspectors on staff, we’ve built our reputation on delivering solutions that protect what matters most—your family’s health and your home’s value.
PFAS, Lead, and Hard Water: Montgomery County’s Triple Threat
Merion Station residents face three primary water quality challenges that demand professional attention. Aqua Pennsylvania has installed multiple PFAS treatment systems across Montgomery County, responding to “forever chemical” contamination near former military installations. Pennsylvania now enforces maximum contaminant levels of 14 parts per trillion for PFOA and 18 parts per trillion for PFOS—among the strictest standards nationwide.
Simultaneously, a 2019 Environmental Working Group study detected lead above health guidelines in Lower Merion’s tap water, raising concerns for families with young children. Older homes may contain lead pipes or solder installed before the 1986 federal ban. At Dierolf, we install certified PFAS filtration systems utilizing reverse osmosis and specialized carbon filtration, while our point-of-use systems provide effective barriers against lead contamination. Our comprehensive approach is detailed at our private well safety guide.
Southeastern Pennsylvania’s geological formations also deliver calcium and magnesium-rich hard water that causes white scale buildup, soap that won’t lather, and premature water heater failure. Professional water softener installation using ion exchange technology removes these minerals before they damage your plumbing infrastructure. We explain the science at our water chemistry guide.
pH Imbalance and Bacterial Contamination
The Schuylkill River and local groundwater sources can exhibit pH levels outside the ideal 6.5-8.5 range. Acidic water dissolves metals from plumbing—including lead, copper, and iron—accelerating pipe corrosion. Our acid neutralizer systems inject calcite media into your water supply, preventing the costly pipe replacements that corrosive water inevitably causes. As we discuss at our water contaminants article, addressing pH problems early saves homeowners tens of thousands in future repairs.
Private well owners in surrounding estates face additional bacterial risks. Pennsylvania DEP guidelines recommend annual testing for coliform bacteria and E. coli. Our ultraviolet disinfection systems provide chemical-free protection, detailed at our UV treatment guide.

Frequently Asked Questions
How often should I test my water in Merion Station? Municipal water customers should test every 1-2 years for hardness, pH, lead, and PFAS. Private well owners need annual testing for bacteria, nitrates, pH, hardness, and metals. Given Montgomery County’s documented PFAS concerns, we recommend including PFAS testing in your panel. Our complimentary consultations help determine which tests make sense for your situation.
Will a water softener remove PFAS or lead? Water softeners excel at removing hardness minerals but don’t address PFAS, lead, or bacteria. Each challenge requires targeted technology: reverse osmosis or specialized carbon for PFAS, certified filters for lead, and UV systems for bacterial contamination. Many homes benefit from layered treatment combining multiple technologies. We explain these systems at our water treatment guide.
My water tastes like chlorine and has sediment. Is this normal? Chlorine taste comes from municipal disinfectants—safe but unpleasant. Sediment may indicate system disturbances or deteriorating internal plumbing. We recommend comprehensive testing followed by whole-house carbon filtration for chlorine and sediment filters at your point of entry. Properly addressed, you’ll enjoy crystal-clear water that tastes fresh from every tap.
