What the violations mean

Total Trihalomethanes (TTHMs)

10 incidents

Disinfection byproduct levels exceeded the federal limit

Long-term TTHM exposure may increase bladder cancer risk

Interim Enhanced Surface Water Treatment Rule

1 incident

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

Where the water comes from

Lajas draws water from 2 wells and 2 surface water intakes (2 of them for emergency, seasonal or other part-time use).

Annual water quality report

Lajas 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.
