What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Massachusetts has 859 active transient non-community water systems, 53% of the state's 1,636 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 14 Massachusetts systems (0.9%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Guilder Hills Homeowners Association?
EPA lists Guilder Hills Homeowners Association as privately owned. The MA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 140 of the 183 active systems in Berkshire County (77%) are also privately owned.
Does Guilder Hills Homeowners Association have drinking water violations?
EPA's records list 5 violations for this system; 4 are health-based, and the most recent began in April 2018. The violations listed here began between October 2005 and April 2018. By type: 4 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 4 as archived and 1 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.
