What Are the Risks at the Site?
There is insufficient information to determine the site-wide human exposure status at the San German Ground Water Contamination Site. The San German Ground Water Contamination site consists of a ground water plume with several potential sources of contamination. The San German Urbano public water system consists of seven wells and two surface water intakes serving an estimated population of 25,000 people. Industrial activity in the area has contributed to contamination of these wells, one of which was ordered closed by the Puerto Rico Department of Health (PRDOH) due to high levels of chemical solvents in the water. Other wells have shown lower levels of contamination during routine monitoring. The contaminants of concern are tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (cis-1,2-DCE). These chemicals are solvents used for degreasing, industrial cleaning, and dry cleaning. The extent of the plume has not yet been determined, but EPA will conduct an RI/FS to define the nature and extent of contamination. The potential exposure pathways are not yet identified; therefore there is insufficient data to determine the status of the site. EPA ensures community participation throughout the remedial process by meeting with residents and affected stakeholders, issuing public notices and updating fact sheets. A site profile has been established on the EPA website to keep the community informed of recent progress at the site. Additionally, an EPA Community Involvement Coordinator is assigned to the site and can address specific community concerns as they arise.
EPA uses performance measures to track environmental results at Superfund sites. If you have any questions or concerns about the measures at this site, please contact the site team members listed under Site Contacts.

|Status at this
|What does this mean?|
|Human Exposure Under Control||Insufficient Data||Yes means assessments indicate that across the entire site:
No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
|Groundwater Migration Under Control||Insufficient Data||
Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.
No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.
Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.
Yes means the physical construction of the cleanup is complete for the entire site.
No means either physical construction is not complete or actions are still needed to address contamination.
|Sitewide Ready for Anticipated Use||No||Yes means:
No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
