Seasons’ Greetings from the Local Water Quality District

It’s that magical time of year again when…snow falls in the mountains and makes its way to recharge zones of the Gallatin Valley aquifer. For most folks outside of the City of Bozeman, this means a steady supply of sand and gravel-filtered drinking water in their homes from their backyard well. This Holiday Season, give the gift of knowing what’s in your loved one’s drinking water well by having their well water tested at a State of Montana certified laboratory.

While the water in the Gallatin Valley aquifer is generally of very good quality, there are still some areas of concern for owners of private domestic wells. For example, did you know that there is naturally occurring arsenic in parts of the Gallatin Valley? Geologic formations associated with ancient and modern Yellowstone volcanic and geothermal features are the source of this arsenic. In fact, water in the mainstem Missouri River exceeds the US Environmental Protection Agency’s maximum contaminant level all the way to Great Falls, Montana.

While elevated arsenic is generally not a valley-wide problem, owners of domestic drinking water wells in the Gallatin and in surrounding communities should have their wells tested annually for things that can occur in groundwater and may impact human health like arsenic, lead, nitrate, and E. Coli bacteria.

This Holiday Season, stop by the Local Water Quality District office and pick up a free well-test kit. Staff can provide guidance on what to test for and interpretation of your results. While the kits are available at no cost, the price of analysis depends on what test is desired and is covered by the well owner.

MONTANA DEQ RELEASES PFAS SURFACE WATER & SEDIMENT MONITORING REPORT

Per- and Polyfluoroalkyl Substances, known as PFAS for short, are widely used and long lasting chemicals that break down very slowly. PFAS can be found in a variety of consumer, commercial, and industrial products, including food products, and in the environment. PFAS are also found in the blood of people and animals worldwide, and scientific studies have shown that exposure to some PFAS may be linked to harmful health effects.

The State of Montana recognized PFAS as emerging contaminants of concern and implemented the
Montana PFAS Action Plan in June of 2020, and began monitoring to determine the prevalence and magnitude of PFAS contamination in surface water in at-risk areas of Montana in 2021.

A new report provides results from water these quality monitoring efforts and discusses next steps.

A Fact Sheet summarizing results from the Bozeman area can be found HERE.

MONTANA DEQ PROVIDES HARMFUL ALGAL BLOOM IDENTIFICATION AND REPORTING RESOURCES FOR WATER RECREATIONISTS

Cyanobacteria, also known as blue green algae, occur naturally in many on Montana’s freshwater systems. Harmful algal blooms (HABs) happen when these organisms grow rapidly, typically when nutrients are abundant and calm water is warmed by a long, hot growing season.

HABs can produce toxins that can cause skin irritation and illness in humans, pets, and livestock. In extreme cases, these toxins can even be lethal if ingested.

The Montana Department of Environmental Quality and Department of Public Health and Human Services HAB website includes resources for heading out on the water safely. You can:

  • educate yourself on HABs: where to look & what to look for when you’re out on the water
  • submit reports of suspected HABs – state or local health agencies will follow up
  • review suspected HABs reported by others, including any associated health advisories or monitoring

Last year in Gallatin County, HABs were reported and confirmed on Hebgen and Hyalite Reservoirs. If you suspect a HAB-related illness in a person or animal, call Poison Control at 1-800-222-1222.


RECENT FLOODING MAY IMPACT DOMESTIC DRINKING WELL WATER QUALITY

Due to the recent flooding events in Gallatin and surrounding counties, residents who rely on a private well for water are strongly encouraged to test their well water for the presence of bacteria.

Wells in flood-impacted areas may be especially prone to contamination from bacteria as rising groundwater levels may interact with nearby septic systems.

Anytime a well has been inundated or the well user suspects contamination due to flood waters, they should follow several important steps to ensure that well water is safe for drinking and general use:

  1. Pick up well-water test kit from the GLWQD office
  2. Follow the instructions to collect a sample from your well water or from a home faucet
  3. Submit the samples to a state-certified laboratory for Bacteria testing (Total Coliform/E Coli.)
  4. If the well water sample comes up positive for E. Coli, follow well disinfection procedures, per the MSU Extension Water Quality office guidelines.
  5. As the effect of floods on well water can persist for months, follow up with routine testing to ensure your well water is safe for consumption.

The City-County Health Department has provided a few quick links to important topics, such as how to inspect your well and septic systems post-flood. Please click here or on the the link below the following image to be redirected to the guidance documents provided by the Health Department.

2021 WATERSHED HEALTH SUMMARY – SURFACE WATER DATA AT A GLANCE

As part of the Surface Water Monitoring Network program, GLWQD develops regular Watershed Health Summaries that present surface water data from the Lower Gallatin Watershed in a non-technical format for all District residents.

GALLATIN STREAM TEAMS IN THE NEWS

The Gallatin Stream Teams volunteer monitoring program was recently featured in the Bozeman Daily Chronicle. This recognition is well-deserved, as Stream Teams volunteers are an invaluable component of GLWQD’s data collection efforts for the Surface Water Monitoring Network program.

GLWQD PUBLISHES 2020 GALLATIN STATE OF THE WATERS REPORT

The Gallatin Local Water Quality District has published the 2020 Gallatin State of the Waters Report. This report is produced every five years to update District citizens on GLWQD’s recent work, and to highlight important findings. Hard copies of the Report are available at the GLWQD office.

STATE RELEASES GUIDANCE VALUES FOR MANGANESE IN DRINKING WATER

The Montana Department of Environmental Quality and the Montana Department of Public Health and Human Services have developed health-based guidance values for manganese in drinking water. Information on the health effects of manganese is an evolving science, and Montana is using a guidance value approach to help Montana families take voluntary steps to ensure that their drinking water is safe.

Because they are guidance values, there are no new or additional regulatory requirements for homeowners or public water systems, but District residents who use private wells as a drinking water source are encouraged to include manganese in their next recommended annual water quality screening. A DEQ/DPHHS factsheet can be found HERE. An associated derivation document is also available.


BIG SKY GROUNDWATER STUDY

A Montana Bureau of Mines and Geology (MBMG) Groundwater Investigation Program (GWIP) study is underway in the Upper Gallatin canyon area of Big Sky. To learn more about this study, take a look at the project fact sheet.
