What the violations mean

Interim Enhanced Surface Water Treatment Rule

61 incidents

The system did not meet a filtration or treatment requirement for surface water

Inadequate treatment of surface water can let pathogens such as Cryptosporidium and Giardia through

Total Trihalomethanes (TTHMs)

14 incidents

Disinfection byproduct levels exceeded the federal limit

Long-term TTHM exposure may increase bladder cancer risk

Haloacetic Acids (HAA5)

4 incidents

Haloacetic acid byproducts exceeded the federal limit

Long-term exposure to HAAs may increase cancer risk

Revised Total Coliform Rule

2 incidents

The system did not meet a requirement of the Revised Total Coliform Rule

Coliform and E. coli rules protect against bacteria in the distribution system

Surface Water Treatment Rule

1 incident

The system did not complete a treatment step or action that the Surface Water Treatment Rule requires (a treatment technique violation).

The utility had to notify customers about this violation.

Where the water comes from

Metropolitano draws water from 10 wells and 5 surface water intakes (10 of them for emergency, seasonal or other part-time use).

Annual water quality report

Metropolitano must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.

Systems serving 10,000 or more people must mail or deliver the report to every customer, and from 2027 they must send it twice a year.

Testing your own water

To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by Puerto Rico.
