Analysis

What to know about Berlin's water

Berlin ranks #219 out of 560 cities in Pennsylvania for water quality, placing it mid-range in the state.

Berlin relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

Lead levels exceed the EPA action level of 15 ppb, which typically indicates aging lead service lines or lead solder in the distribution system. An NSF 53-certified filter is strongly recommended for drinking and cooking water.

As a small community water system, Berlin may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

Where does Berlin's water come from?

Berlin's drinking water comes from groundwater (wells), supplied by 1 water system serving approximately 2,468 people. Groundwater is generally less susceptible to surface contamination but can contain naturally occurring contaminants like arsenic, radon, and nitrate.

What Berlin residents can do

Install a water filter

Recommended: NSF 53-certified pitcher or under-sink filter. This addresses the specific contaminants found in Berlin's water.

Request your utility's CCR

Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.

Flush your taps

Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.

Monitor alerts during storms

Berlin's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.

Where Berlin's water comes from

Groundwater

Berlin's drinking water is drawn from underground aquifers through wells.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.

Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.

The system is operated by local government ownership and serves approximately 2,468 people through 1 water system.
