Does Green Investments have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2014. The violations listed here began between January 2012 and January 2014. By type: 12 monitoring and reporting. The contaminants or rules involved are Chromium, Cadmium, Antimony and Selenium. EPA lists 10 as archived and 2 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
