The Monte Vista Tank Service Area of the El Dorado Irrigation District’s Main Water System Has Levels of Haloacetic Acids (five) Above Drinking Water Standards

Click here for a map of the affected area.

This letter is to inform you that our water system serving your area recently violated a drinking water standard. Although this is not an emergency, you, as our customer, have a right to know what happened, what you should do, and what we are doing to correct this situation.

We routinely monitor for the presence of drinking water contaminants. Average testing results we received between February 10, 2016 and November 8, 2016 show that our system serving your area exceeded the maximum contaminant level (MCL) for Haloacetic Acids (five). The maximum contaminant level for Haloacetic Acids (five) is 60 micrograms per liter. The average level of Haloacetic Acids (five) during the period from February 10, 2016 and November 8, 2016 was 62 micrograms per liter.

As a result of disinfecting drinking water, disinfectant byproducts may form. Design and/or disinfection modifications may reduce the level of disinfection byproducts in drinking water.

What should I do?

You do not need to boil your water nor take any other corrective actions. However, if you have specific health concerns, please consult your doctor.

What does this mean?

This situation does not require that you take immediate action. If it had, you would have been notified immediately.

The California State Water Resources Control Board, Division of Drinking Water (Division) sets drinking water maximum contaminant levels and also requires the disinfection of drinking water. However, when used in the treatment of drinking water, disinfectants react with naturally-occurring organic and inorganic matter present in water to form chemicals called disinfection byproducts (DBPs). The Division has determined that a number of DBPs are a health concern at certain levels of exposure. Some people who drink water containing haloacetic acids in excess of the MCL over many years may have an increased risk of getting cancer.

What is being done?

As part of our ongoing efforts to supply the highest quality drinking water to our customers, we are implementing operational practices and/or design modifications that will reduce the formation of disinfection by-products in your drinking water.
