Exeter and Birdsboro water: common questions
Who supplies water in Exeter Township?
Mostly Pennsylvania American Water's Glen Alsace system, which serves parts of Exeter, Amity, Douglassville and St. Lawrence. Berks County also lists Mt. Penn Borough as serving part of Exeter. Your water bill names your supplier.
Is Exeter water hard?
Yes, very. Pennsylvania American Water's 2025 Glen Alsace report shows hardness averaging 272 mg/L, about 16 grains per gallon, with a range of 80 to 360 mg/L. Penn State Extension calls anything over 180 mg/L very hard.
What else does the 2025 Glen Alsace report show?
Copper at the 90th percentile was 1.45 ppm, above the 1.3 ppm action level, with 7 of 60 homes over it; the utility says it is optimizing treatment. PFOS reached 11.1 parts per trillion at one entry point (state limit 18), and trihalomethanes ran up to a 73.5 ppb annual average (limit 80).
What is the new Exeter water treatment plant?
Pennsylvania American Water announced in December 2025 a new plant that will draw from the Schuylkill River, with UV disinfection, PFAS removal and granular activated carbon. Construction is planned to start in 2028, with completion expected in 2030.
Who supplies water in Birdsboro?
The Birdsboro Municipal Authority, which serves the borough and part of Union Township. Its 2025 report says water comes from springs in the surrounding mountains, collected in the Indian Run and Stinson Run reservoirs, Dyer Quarry and Hay Creek, and is treated with membrane filtration and chlorine.
Is there lead in Birdsboro water?
The authority's 2025 testing found no lead at the 90th percentile, with none of 21 sites over the action level. More than a third of Birdsboro's homes were built before 1940, so lead solder and old fixtures are worth checking.
Do you serve Exeter and Birdsboro?
Yes. Exeter is about 20 minutes and Birdsboro about 25 minutes from our base in Sinking Spring. Call (610) 400-3132 or book a free water test.
