Water Quality

The Mohawk Valley Water Authority is the premier water supplier serving portions of Oneida and Herkimer Counties in the greater Utica area.

The Water Quality Laboratory of the Mohawk Valley Water Authority offers microbiological analysis of water including tests for total coliform, E Coli, heterotrophic bacteria, as well as testing for nitrate and nitrite. Our laboratory, approved by the U.S. EPA, is one of 36 laboratories nationwide accepting outside samples to test for waterborne pathogens such as Giardia and Cryptosporidium. Other services offered to the industry include micro-particulate analysis, source water and stream water assessments, treatment plant validation and optimization and distribution system water and quality analysis.

The Water Treatment Plant is a grade A plant that is capable of processing up to 32 million gallons of water daily. The water source comes from a reservoir which is located at the foothills of the Adirondacks. The water is processed through our state of the art filtration system and then distributed to the customers of MVWA. The plant is staffed with 7 highly trained certified operators. The operators are all trained in laboratory analysis, process control, and plant maintenance. The operation is supervised by the chief operator, Kim Hoffman.

Annual Water Quality Report (AWQR) - Click Here

To comply with State and Federal regulations the Mohawk Valley Water Authority (MVWA), will be annually issuing a report describing the quality of your drinking water. The purpose of this report is to raise your understanding of drinking water and awareness of the need to protect our drinking water sources. We are proud to report that last year, the water provided by the Mohawk Valley Water Authority meets or surpasses all Federal and New York State Drinking Water Standards. This report provides an overview of the 2011 water quality results. Included are details about where your water comes from, what it contains, and how it compares to State and Federal standards.

Basic Information

The EPA has developed the Long Term 2 Enhanced Surface Water Treatment Rule (LT2 rule) to improve your drinking water quality and provide additional protection from disease-causing microorganisms and contaminants that can form during drinking water treatment.

    Your drinking water comes from source water locations such as:

  • Lakes
  • Rivers
  • Reservoirs
  • Ground water aquifers

Pathogens, such as Giardia and Cryptosporidium, are often found in water, and can cause gastrointestinal illness (e.g., diarrhea, vomiting, cramps) and other health risks. In many cases, this water needs to be disinfected through the use of additives such as chlorine to inactivate (or kill) microbial pathogens.

Cryptosporidium is a significant concern in drinking water because it contaminates surface waters used as drinking water sources, it is resistant to chlorine and other disinfectants, and it has caused waterborne disease outbreaks. Consuming water with Cryptosporidium, a contaminant in drinking water sources, can cause gastrointestinal illness, which may be severe in people with weakened immune systems (e.g., infants and the elderly) and sometimes fatal in people with severely compromised immune systems (e.g., cancer and AIDS patients).

The purpose of the LT2 rule is to reduce disease incidence associated with Cryptosporidium and other pathogenic microorganisms in your drinking water. The rule applies to all public water systems that use surface water or ground water that is under the direct influence of surface water. The rule will bolster existing regulations and provide a higher level of protection of your drinking water supply by:

  • Targeting additional Cryptosporidium treatment requirements to higher risk systems
  • Taking actions to reduce risks from uncovered finished water storage facilities
  • Making provisions to ensure that systems maintain microbial protection as they take steps to reduce the formation of disinfection byproducts

This combination of steps, combined with the existing regulations, is designed to provide protection from microbial pathogens while simultaneously minimizing health risks to the population from disinfection byproducts.

The Safe Drinking Water Act (SDWA) was signed into law on December 16, 1974. The purpose of the law is to assure that the nation's water supply system serving the public meet minimum national standards for the protection of public health.
