Question and Answer

Background

The Utah Department of Environmental Quality’s (DEQ) Division of Drinking Water (DDW) is addressing reported issues with culinary water at The Highland Subdivision in Morgan County. In Spring 2020, customers reported discolored water in their homes. As a result, DDW required the water system to collect additional water samples.

These additional water samples were collected from homes in the subdivision as well as from the springs that serve as the water source for the system. The samples were analyzed for bacteria, lead, copper, iron, manganese, pH, and alkalinity. A summary of sample results can be found in the “Sample Data Summary” section on this page.

Elevated copper levels were detected in six out of 20 samples collected from homes during the months of May, June, and July 2020. The elevated results ranged from 1.31 mg/L to 1.91 mg/L. The EPA Action Level for Copper is 1.30 mg/L. Consuming water with copper concentrations above the EPA’s Action Level may cause negative health effects. See the “Health Effects of Copper” section below for more information.

In June 2020, DDW required the water system to issue a public notice to all customers due to high copper results. Find the public notice here (2 MB).

What Customers Can Do

If customers are curious about the levels of copper, lead, or other contaminants at their specific residence, they should have their water tested by a certified laboratory (132 KB). Customers should be aware that water quality can vary from one residence to another based on several factors, including the type of plumbing materials in each residence. Customers should consult with their physician if they have questions about their personal exposure to certain contaminants and any associated health effects.

Health Effects of Copper

Copper is a mineral and natural component in soils. In the correct amounts, it is an essential nutrient for humans and plants. Copper is widely distributed within the tissues of the body but accumulates primarily in the liver and kidneys.

The primary short-term health effect of excessive copper exposure is GI distress. Long-term health effects include liver and kidney damage. A single dose of 15 mg/L of copper can cause nausea, vomiting, diarrhea, and intestinal cramps. Severe cases of copper poisoning can lead to anemia and disruption of liver and kidney functions. Individuals with Wilson’s or Menke’s diseases are at higher risk from copper exposure.

Copper in drinking water normally comes from household plumbing rather than from the water system sources. Copper enters drinking water when plumbing materials containing copper (such as copper pipes or other components) react with water as it passes through. In addition to the amount of copper-containing materials present in a building, the chemistry of the water being delivered to the building plays an important role in the amount of copper that may be released into the drinking water.

Level 2 Assessment

  • On September 24, 2020, the Division conducted a Level 2 assessment to identify deficiencies of the system: Level 2 Assessment Report (298 KB)

DDW Permitting

The Permitting Section of the DDW reviews all plans and specifications for compliance with the applicable Safe Drinking Water regulations (Utah Annotated Code R309-500).

All public drinking water projects must receive DDW Plan Approval (construction permit) and Operating Permit before being placed into service. R309-500-5(1)(a) defines a drinking water project as any construction, addition, modification of a drinking water facility that may affect the quality or quantity of water delivered.

Highland Subdivision is compliant with the Permitting Section of DDW regarding all of their drinking water projects. All Permitting Section documents with Division Approval can be found using our EZ Search tool.
