See the ledger ↓La Pica's drinking water received a grade of B- (73.9 out of 100), indicating fair water quality. The city's 1 water system serves approximately 561 residents using surface water.
Lead levels were measured at 12.0 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 73 violations on record, including 31 health-based violations. 8 remain unresolved.
La Pica ranks #20 out of 101 cities in Puerto Rico for water quality, placing it above average in the state. The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, La Pica may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in La Pica's water
Every contaminant flagged in La Pica, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.
Near Limit — EPA Action Level: 15 ppb
Within EPA limits but above the American Academy of Pediatrics recommended level of 1 ppb — no lead level is considered safe for children. An NSF 53-certified filter provides additional protection, and running the cold tap 30 seconds after stagnation reduces exposure.Full contaminants report

03La Pica's ten-year track record
Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 73 violations on record, including 31 health-based violations. 8 remain unresolved.
5 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.

Filter drinking & cooking water
NSF-certified water filter. Lead detected at 12.0 ppb
Compare tested filters →Flush taps & check your service line
