Questions people ask

Who is my water provider in Pinellas County?

Pinellas County Utilities is the main water provider for Pinellas County. Some addresses can be served by a different system, so check your water bill: it names your utility.

How do I contact Pinellas County Utilities?

Call (727) 464-4000 or visit https://pinellas.gov/utilities-business-customer-services-contact-information/. Billing and outages are handled by the utility, not by ScoreYourWater.

Which ZIP codes does Pinellas County Utilities serve?

EPA water system boundaries do not match Pinellas County Utilities to any ZIP code area in our data. Your water bill names your utility. Source: EPA Water System Boundaries (CWS service area boundaries) v3.0, March 2026 release.

Does Pinellas County Utilities buy water from another system, or sell water to others?

Pinellas County Utilities buys water from Tampa Bay Water (Regional Surface Water Treatment Plant), Tampa Bay Water (Cypress Creek) and City of St. Petersburg. In this data, City of Clearwater and City of St. Petersburg buy water from it. (July to September 2026 extract.)

How many contaminants in Pinellas County Utilities's water are above published health guidelines?

5 of 29 detected contaminants were above their published health guidelines in EPA SDWA, EPA UCMR and Florida DEP data, 2018-2025. The highest: Arsenic at 85 times its guideline, Bromodichloromethane at 56 times its guideline and Dibromochloromethane at 38 times its guideline.

What is chloramine, and does Pinellas County Utilities use it?

Chloramine is a disinfectant made by combining chlorine and ammonia. Some water systems use it in place of free chlorine. The public data used on this site (EPA SDWA, EPA UCMR and Florida DEP data) does not record which disinfectant Pinellas County Utilities uses, so we do not say. Your utility can tell you.

How is the Water Score for Pinellas County Utilities calculated?

The score starts at 100. It goes down 8 for each contaminant above a cited health guideline whose source states a cancer basis, 5 for each other contaminant above its cited guideline, 5 for each of PFOA and PFOS averaging above the 4.0 ppt limit in EPA's 2024 PFAS rule, 10 for each contaminant whose average of all samples is above EPA's legal limit (instead of its guideline step), and 1 for each contaminant with a cited cancer-based guideline that is detected below it. Only guidelines with a cited document count. The lowest score is 5. Higher is better. For this report: 100 minus 8 times 5 is 60, so the score is 60.

What is the difference between a health guideline and a legal limit?

A legal limit is an enforceable standard, set by the EPA under the Safe Drinking Water Act. Limits weigh health research together with the cost and feasibility of treatment. A health guideline is published by public-health sources and based on health research alone. A utility can meet every legal limit and still be above a published health guideline.
