In 1978 Catoctin began a long-term water quality-monitoring program so the streams could be closely watched for signs of pollution and other problems. This monitoring program entails monthly water samples to be analyzed from eight sites within the park. These samples are analyzed in the lab for temperature, dissolved oxygen, pH, ammonia, salinity, specific conductivity, turbidity, and alkalinity. Regular testing of Catoctin’s streams ensures that any water quality problems can be quickly recognized and dealt with.
Biologists from the Maryland Department of Natural Resources have conducted macroinvertebrate sampling on Big Hunting Creek and Owens Creek since 1981. Benthic macroinvertebrates are animals that live in lakes and streams that are large enough to be seen with the naked eye. Included in this group are insects, crustaceans, mollusks, and annelids. Sampling these animals offers additional water quality information and can demonstrate the impacts of pollution. High diversity of these sensitive organisms has been found in both Big Hunting Creek and Owens Creek indicating that the water quality is good.
In 2002 Catoctin received funding to complete a more extensive stream water quality study. This two-year study will examine surface water and stream sediments for heavy metals, pesticides, and bacteria concentrations in five stream locations. To date, samples have been tested twice and the results have showed slightly elevated amounts of aluminum at one location. No other significant contaminations were found at the remaining sites.

The first Job Corps Center in President Johnson’s “War on Poverty,” operated from 1965-1969. Goals were to combine work, education, and recreation “to create a desire to become happy, useful, and self-supporting citizens,” to “create a good work attitude,” and to improve reading and math skills.
