The Saints Peter and Matthew the Apostles Parish Church of Toa Baja (Spanish: Iglesia Parroquial de los Apóstoles San Pedro y San Matías), better known as the St. Peter the Apostle Parish Church of Toa Baja (Iglesia Parroquial de San Pedro Apóstol de Toa Baja), is a historic 16h-century Roman Catholic parish church located in the main town square (plaza pública) of Toa Baja Pueblo, the administrative and historic center of the municipality of Toa Baja, Puerto Rico.The church is notable for having its façade facing the La Plata River rather than the town square as it is usual in Puerto Rican towns (pueblos). Local tradition states that this was due to historical floods and consequent modifications made to the church. A small chapel that dated to before the official founding of Toa Baja used to occupy the site of the current church. The current façade, similar to that of the parish church of Vega Alta, dates to the 18th century. The church is of artistic notability for its chiseled gold and silver rococo ornamentations, described by Iñigo Abbad y Lasierra in 1775 as one of the best adorned in the island.

The Dorado Ground Water Contamination Site is one of 18 sites listed on the EPA’s National Priorities List in Puerto Rico, a territory of the United States, identified as posing a risk to human health and/or the environment because of a contamination plume in the underlying karst aquifer. Located in north-central Puerto Rico, 20 mi (32 km) to the west of the capital city, San Juan, the Dorado Ground Water Contamination site is located within the Maguayo and Dorado Urbano public water systems, and is the source of drinking water for more than 67,000 people. This site first came under scrutiny by officials in the 1980s and it was officially added to the EPA's Superfund list on September 9, 2016. The EPA is in the process of examining the precise extent and location of this contaminated groundwater plume and, at this time, the contaminants cannot be attributed to any specific source. In the wake of Hurricane Maria, the site has come under increased scrutiny because locals desperate for a source of safe drinking water have been using wells on the superfund site.
