💧 Where Does Your Water Come From?

Groundwater

Aromas Water District's water is pumped from underground aquifers. Groundwater is naturally filtered through rock and soil, but it can be vulnerable to PFAS contamination, nitrates from agriculture, and industrial chemicals that seep into the water table.

Source water assessment from Aromas Water District Consumer Confidence Report:
Assessments of the drinking water sources for the District were completed in 2002 and 2012. A source water assessment lists possible contaminating activities that might affect the quality of your water sources. The assessment also identifies the susceptibility of the District's drinking water wells to identified contamination threats. Residential septic systems, other animal operations, and agricultural irrigation are the greatest threats to the District's drinking water.

Treatment regime

How this utility classifies its treatment process and what each reported treatment chemical does.

Treatment classification
Minimal — disinfection only
Disinfection (typically chlorine) without additional filtration or coagulation stages. Common for groundwater systems where source water meets federal standards after disinfection alone.

Watershed exposure sources reported

Land-use and natural conditions identified in the utility's source-water assessment as potential contamination sources upstream of treatment.

Residential septic systemsAnimal operationsAgricultural irrigation

Treatment intensity is a ZipCheckup-derived classification based on the chemicals and processes the utility reports. Chemicals and contamination sources are taken verbatim from the utility's CCR filing. Routine federal monitoring and contaminant testing shown elsewhere on this page determine whether the water meets safety standards, not the treatment classification.

Aesthetic water quality

These measurements describe the look, taste, and feel of the water this utility delivers. They are not contaminant violations — they sit alongside federal Secondary Maximum Contaminant Levels (SMCLs) which the EPA publishes as non-enforceable guidance.

pH

How acidic or basic the water is on a 0-14 scale. Drinking water is typically near neutral.
EPA secondary range: 6.5 – 8.5

Aesthetic measurements from Aromas Water District Consumer Confidence Report.

Aesthetic measurements are reported by the utility from its annual sampling. EPA Secondary MCLs are advisory thresholds — values outside them indicate aesthetic concerns such as taste or appearance, not health violations. Federal contaminant testing is shown in the sections above.

Hard water detected in Aromas Water District

Your utility reported water hardness of 130 ppm CaCO₃ (7.6 grains per gallon) in its most recent Consumer Confidence Report. This is in the moderately hard range and may cause scale buildup, reduced appliance lifespan, and dry skin or hair.

Solutions for hard water

There are three common approaches to treating hard water: salt-based ion-exchange softeners (most effective, require salt refills), salt-free conditioners (lower maintenance, scale prevention only), and reverse osmosis at the kitchen sink (cooking and drinking water only). Aquasana, EcoWater, Pelican, and SpringWell are among the major US brands.
