Is Brooklyn Park, MN Tap Water Safe to Drink?
Brooklyn Park tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 10.05 ppt, PFOS: 7.63 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water. Brooklyn Park also has very hard water at 240 PPM.

How Brooklyn Park Compares
Brooklyn Park's water is 74% harder than the national average of 138 PPM. It ranks #213 out of 1000 cities in our database (harder than 79% of US cities we track). Within Minnesota, it ranks #10 of 16 cities (11% above the state average of 216 PPM). Among cities (50k-100k), Brooklyn Park ranks #71 of 258 for hardness. At this hardness level, water heaters run an estimated 44% less efficiently due to scale insulation, and major water-using appliances typically last 3 years less than the national average lifespan.
What Brooklyn Park's Water Means for Your Home
Hardness: 240 PPM - Treatment Recommended
Brooklyn Park has some seriously hard water. At 240 PPM (14 grains per gallon), your tap is loaded with dissolved calcium and magnesium picked up from underground limestone and dolomite formations. Here's the thing: it's perfectly safe to drink. The minerals won't hurt you. But they will hurt your wallet. That adds up. Hard water at 240 PPM increases household costs through scale-coated water heaters that use more energy, extra soap and detergent, and appliances that wear out faster. Most Brooklyn Park homeowners don't realize it until the plumber shows up. That's 11% harder than the Minnesota average.
Contaminants & Safety
Forever chemicals (PFAS) are a serious concern here. Brooklyn Park has PFOA at 10.05 ppt and PFOS at 7.63 ppt — the EPA's 2024 limit is 4 ppt for PFOA and PFOS individually. PFAS don't break down in your body or the environment. Research links long-term exposure to increased cancer risk, thyroid issues, and immune system problems. The fix: a whole-house activated carbon filter or a point-of-use reverse osmosis system. Look for NSF P473 certification — that's the standard that specifically tests for PFAS removal.
What's in the Treatment Process
Even though Brooklyn Park draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 29.3 ppb and HAA5 at 9.55 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines.
Chromium-6 is naturally present in Brooklyn Park's aquifer geology at 0.0438 ppb — 2.2x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
How Hard Water Affects Your Home
At 240 PPM, untreated hard water has measurable effects on household costs and appliance life:
- Water heater inefficiency: Scale insulation forces the heater to work harder (DOE estimates up to 22% more energy for heavily scaled units)
- Soap and detergent: Hard water reduces lathering, requiring significantly more product
- Appliance replacement: Water heaters, dishwashers, and washing machines fail 2-4 years earlier due to scale buildup
- Plumbing maintenance: Scale buildup in pipes reduces flow and requires more frequent service
Note: Impact varies by household size, water usage, and local energy costs. A home water test provides the most accurate assessment for your specific situation.

About Brooklyn Park's Water Supply
Water Utility: City of Brooklyn Park Water
Water Source: Mississippi River & wells (Groundwater)
Population Served: 89,995
Hardness: 240 PPM (14 grains per gallon)
Brooklyn Park draws its drinking water from groundwater sources — Mississippi River & wells. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why hardness is elevated here. Calcium and magnesium dissolve into the water as it moves through limestone and dolomite. The system serves 90,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Brooklyn Park Water's Consumer Confidence Report (CCR) or test your own tap.

Water Softener Sizing for Brooklyn Park
At 240 PPM (14 GPG), here is how to size a softener for your Brooklyn Park home. Multiply hardness in GPG (14) by daily water usage (roughly 50 gallons per person). A family of four uses about 200 gallons/day: 14 GPG × 200 gal = 2800 grains/day. Over a 7-day regeneration cycle, that is 19,600 grains - a 32,000-grain softener is the right fit for most Brooklyn Park households.
