Water Quality Monitoring

Testing and monitoring are key tools in our ongoing stewardship of water quality and public health.

NEIGHBORHOOD WATER WATCH

Neighborhood Water Watch (NWW) is a fast-paced community driven collaborative program between CRK and neighborhood groups, schools and citizens in our watershed. The goal is to work together to assess and improve water quality in urban streams, while protecting human health in neighboring communities.

Concerned citizens from all reaches of north Georgia bring water samples from over 200 stream stations to CRK’s laboratories, as part of NWW. Water samples are promptly analyzed for turbidity, conductivity, optical brighteners, and E. coli. Any threats indicated are addressed by CRK, as we work with local governments, neighborhood groups, and leaders to stop public health threats and restore our streams.

NWW data is also uploaded weekly to the Georgia Adopt-A-Stream database. Click here to learn more about Georgia Adopt-A-Stream.

To learn more about the Neighborhood Water Watch program, take a look at our full program description. If you have any questions, including how you can get involved, contact Mike Meyer, Program Director, at (404) 352-9828 or mmeyer@chattahoochee.org.

We collect thousands of samples from the Chattahoochee River and its tributaries, in places that are not routinely monitored by government agencies.

BACTERIALERT

The mission of the BacteriAlert program is to collect water samples at three Chattahoochee River locations in the Chattahoochee River National Recreation Area (Medlock Bridge, Powers Ferry and Paces Ferry) to assess how safe the water is for swimming, wading and boating.

The program is a public-private partnership between CRK, U.S. Geological Survey (USGS), and the Chattahoochee River National Recreation Area (CRNRA).

Results are posted on the USGS BacteriAlert webpage within 24 hours of data collection. Using predictive formulas, the website also provides current estimates of E. coli bacteria levels in the river, based on real-time turbidity conditions.

DISSOLVED-OXYGEN MONITORING

Since 2008, at 15 river locations downstream of Atlanta, CRK has monitored dissolved oxygen levels—a key indicator of a river’s health. This initiative is driven by our growing concern that low water levels in summer—which can result in low dissolved oxygen levels—may be harming the river’s ecosystem and water quality, as well as impacting the health of the communities and wildlife dependent upon it.

NUTRIENT MONITORING

Lakes tend to collect and hold nutrients, such as nitrogen and phosphorus as they flow into the lake from…

  • Agricultural and industrial areas
  • Municipal wastewater treatment facilities
  • Septic tanks
  • Lawn fertilizers, and more…

Higher concentrations of nutrients in a lake can drive excessive algae growth, which, in turn, can have devastating impacts on fish stocks and drinking-water supplies.

CRK conducts monthly monitoring of nutrient levels in Lake Lanier and in West Point Lake between April and October. Because our sampling and quality-assurance plans are approved by the Georgia Environmental Protection Division (EPD), our data is used by EPD and others to make important regulatory decisions.

I’ve probably had two or three contamination issues in the spots I collect water from.  If it wasn’t for us out here doing this…we wouldn’t know half of what was going in our rivers and waterways.
