These are the contaminants your filter needs to address, ranked by how close they are to EPA limits.
| Contaminant | Detected Level | EPA Limit | % of Limit | Status |
|---|---|---|---|---|
| Total Trihalomethanes | 59.8593 ug/L | 80 ug/L | 75% | Elevated |
| Arsenic | 0.0046 mg/L | 0.01 mg/L | 46% | Safe |
| Haloacetic Acids | 23.7753 ug/L | 60 ug/L | 40% | Safe |
| Nitrite | 0.3655 mg/L | 1 mg/L | 37% | Safe |
| Copper | 0.448 mg/L | 1.3 mg/L | 35% | Safe |
| Nitrate | 3.3749 mg/L | 10 mg/L | 34% | Safe |
| Chromium | 0.0287 mg/L | 0.1 mg/L | 29% | Safe |
| Lead | 0.0041 mg/L | 0.015 mg/L | 28% | Safe |
Based on Tucson's specific contaminant profile, here are the filter types we recommend.
Your water contains lead, arsenic, nitrates, fluoride — reverse osmosis is one of the most effective filtration methods for removing these specific contaminants. RO systems push water through a semipermeable membrane that blocks up to 99% of dissolved contaminants.
Your water contains disinfection byproducts. Activated carbon filters use adsorption to trap these contaminants as water passes through the carbon media. They are highly effective at improving taste and removing organic chemicals.
Your water contains nitrates, which are particularly concerning for infants and pregnant women. Ion exchange filters swap harmful ions like nitrate for harmless ones like chloride, effectively reducing nitrate levels.
Our recommendations are based on city-wide data. For the most accurate results, test your home's specific water — contaminant levels can vary by neighborhood and plumbing age.

| Filter Type | Removes | Best For | Price | Maintenance |
|---|---|---|---|---|
| Pitcher Filter | Chlorine, taste, odor, some metals | Basic taste improvement, budget-conscious | $20 - $50 | Replace filter every 1-2 months |
| Faucet Mount | Chlorine, lead, some bacteria, VOCs | Convenient, no counter space needed | $20 - $80 | Replace filter every 2-3 months |
| Under-Sink Carbon | Chlorine, VOCs, PFAS, lead (certified models) | Families wanting better filtration without RO | $50 - $300 | Replace filter every 6-12 months |
| Reverse Osmosis | Lead, arsenic, PFAS, nitrates, fluoride, 99% of contaminants | Comprehensive contaminant removal | $150 - $600 | Replace filters annually, membrane every 2-3 years |
| Whole House | Chlorine, sediment, rust, VOCs, some metals | Filtering all water in the home | $300 - $1,500 | Replace filters every 6-12 months |
Tucson uses a mix of surface water and groundwater sources. This means your water may contain a broader range of contaminants — both the organic compounds common in surface water and the dissolved minerals found in groundwater. A versatile filtration system like reverse osmosis or a multi-stage filter is often the best approach for mixed-source water.
Tucson is served by 1 water system, serving a population of approximately 542,629 residents in Pima County.
Yes, a water filter is strongly recommended for Tucson residents. With a water quality score of 68/100, your water has 8 contaminants at notable levels. A quality filter can significantly reduce your exposure to these contaminants and improve the safety and taste of your drinking water.
Based on Tucson's water quality data, the most important contaminants to filter are Total Trihalomethanes, Arsenic, Haloacetic Acids. We recommend a Reverse Osmosis System, which removes: Lead, Arsenic, PFAS/PFOA, Nitrates, and more. Different filter types target different contaminants, so choosing the right one depends on your specific water profile.
For Tucson residents on a budget, a faucet-mount filter ($20-$80) offers the best value. These provide better filtration than pitchers and are more convenient. Look for NSF/ANSI 53 certification, which means the filter is tested for health-related contaminants like lead. If your budget allows, an under-sink carbon filter ($50-$150) provides even better filtration for a modest investment.
Given Tucson's water quality score of 68/100, a whole house filter is worth serious consideration. It treats all the water entering your home, which means filtered water for drinking, cooking, bathing, and laundry. This is particularly valuable when there are multiple contaminants at elevated levels. Budget $300-$1,500 for the system plus professional installation.
Filter recommendations are based on publicly available water quality data from EPA and state regulatory databases. Individual water quality may vary based on your specific location within Tucson, the age and condition of your plumbing, and seasonal fluctuations. Always test your water for the most accurate results. The filter types recommended on this page are general guidance — specific product performance may vary. Consult with a water treatment professional for complex contamination issues.
