How does Guide Dogs for the Blind Inc. compare with other water systems in Clackamas County?

By EPA's size categories, Guide Dogs for the Blind Inc. is a very small system (500 people or fewer). Clackamas County has 241 active public water systems. Its population served is well below the county average of 1,602 people per system, and accounts for less than 0.1% of the 385,972 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Guide Dogs for the Blind Inc. is well below that figure.

What does “non-transient non-community water system” mean?

A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Oregon has 346 active non-transient non-community water systems, 14% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.

Who owns and regulates Guide Dogs for the Blind Inc.?

EPA lists Guide Dogs for the Blind Inc. as privately owned. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 155 of the 241 active systems in Clackamas County (64%) are also privately owned.

Does Guide Dogs for the Blind Inc. have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between January 2022 and January 2026. By type: 9 monitoring and reporting, 1 monitoring, 1 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (5 of them). EPA lists 11 as resolved and 1 as archived. 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. 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.
