Water Quality Monitoring
Buffalo National River's water quality monitoring efforts are divided into two categories: programs and projects. Programs provide long-term monitoring data and are used to better understand trends in water quality, while projects are generally shorter-term, more varied, and more targeted investigations. At any given time, the park may have multiple projects under way to better understand particular aspects of water quality in the Buffalo River or its tributaries.
The Water Quality Monitoring Program was started in 1985 and is a partnership with the Arkansas Department of Environmental Quality (ADEQ). Water quality samples are collected by Buffalo National River staff using ADEQ methods, and water chemistry samples are passed to the ADEQ Laboratory through chain-of-custody via ADEQ Water Quality Inspectors. The park also maintains a continuous dissolved oxygen monitoring program.
Buffalo National River processes many of the collected water samples in the park’s Environmental Protection Agency (EPA)-certified laboratory. As of 2017, Buffalo National River’s water quality laboratory is certified for analysis of Escherichia coli, turbidity, dissolved oxygen, and pH.
If you would like to request a copy of specific data collected by Buffalo National River, please contact the park. Please be sure to include the specific type of data you are requesting and the time period of interest.
Some common water quality data types of interest include:
Please note, all nutrient data can be accessed using EPA’s STORET database, and instructions on how to access STORET are below.

Water Quality Reports
Some of Buffalo National River’s water quality-related reports available by emailing the park are:
Buffalo National River Science Symposium
The first annual Buffalo National River Science Symposium took place in Harrison on Tuesday, April 23. Scientists and researchers from multiple agencies presented historic and current water quality projects and data collected. The following presentations from the Science Symposium are available upon request:
For a digital copy of these presentations, please contact Ecologist Shawn Hodges.
Aquatic Invertebrate Monitoring
Aquatic invertebrates are an important tool for understanding and detecting changes in ecosystem integrity, and they can be used to reflect cumulative impacts that cannot otherwise be detected through traditional water quality monitoring.
The full report Aquatic Invertebrate Monitoring at Buffalo National River, 2005-2013 is availble by emailing the park.
BioBlitz: Opportunity for Citizen Science
Looking for an opportunity to become a citizen scientist? Buffalo National River, in conjunction with the Heartland Network and Missouri State University, sponsors BioBlitzes that occur in the park throughout the year. BioBlitzes are an excellent way to help the park acquire crucial science data that is often used in the decision making process.
Assessment of Escherichia coli Concentrations in the Surface Waters of Buffalo National River
Buffalo National River has conducted a water quality monitoring program for nearly twenty five years and bacteria monitoring has been a major component of that program. In 2009 the monitoring program added Escherichia coli as a parameter to supplement the fecal coliform sampling already being conducted. Escherichia coli has been found to be a much better indicator of possible human pathogens in surface waters, and quantification and enumeration methods for Escherichia coli are much more efficient and accurate.

Amphibians and Reptiles
Prior to 2002 only cursory surveys of herpetological species had been performed in isolated areas of Buffalo National River. Those limited surveys, however intriguing, did not provide enough information to allow park managers to make appropriate decisions to insure long term sustainability of herpetofaunal species and abide by the NPS mission statement. The survey report: A Herpetofaunal Inventory of Buffalo National River, conducted between March 2002 and September 2003, is available by emailing the park.
