Regional Stream Quality Assessments



The Southeast Regional Stream Quality Assessment (SESQA)

Data are in review and are not yet available for download.

Algae, benthic invertebrates, and fish communities were sampled and physical habitat assessed once at all 121 sites during the summer of 2014. Samples were collected along multiple transects within the stream reach following USGS NAWQA protocols.

Water samples were collected weekly at 77 sites for up to 10 weeks preceding the ecological sampling. Water samples were analyzed for nutrients, suspended sediment, major ions, and about 240 dissolved pesticides and pesticide degradates. Selected samples also were analyzed for mercury, pharmaceuticals, wastewater indicator compounds, volatile organic compounds, and hormones.

Passive polar organic chemical integrative samplers (POCIS) were deployed at 77 sites for about 7 weeks to collect dissolved chemicals from stream water. The POCIS are designed to accumulate chemicals such as water-soluble pesticides and degradates, pharmaceuticals, and wastewater indicator compounds.

Streambed sediment was sampled coincident with the ecological sampling at all 121 sites. Stream bottom sediment was collected from depositional areas, composited, and sieved. Sediment samples were analyzed for trace elements, polycyclic aromatic hydrocarbons (PAHs), and halogenated organic compounds (compounds, such as DDT, that contain chlorine or bromine atoms).

Bed-sediment samples from the 59 urban sites were used in standard whole-sediment toxicity tests conducted with amphipod crustaceans (Hyalella azteca 28-day exposures), midge larvae (Chironomus dilutus 10-day exposures) and freshwater mussels (Lampsilis siliquoidea 28-day exposures) to measure potential effects of contaminants on survival and growth. Amphipods, midges, and mussels are sensitive to many contaminants, notably metals and organic contaminants, including insecticides in current use. A number of species of freshwater mussels and fish, such as the Carolina heelsplitter (Lasmigona decorata), spotfin chub (Erimonax monachus) and Etowah darter (Etheostoma etowahae) are threatened or endangered in Southeastern streams.

Stream water-level and temperature were monitored continuously at all 121 sites, and continuous water-quality monitoring was employed at about 20 sites. Continuous monitoring for characteristics such as the amount of dissolved oxygen in water (all 20 sites) and nitrate concentration (6 sites), in conjunction with periodic sampling of nutrients and the attached-algal biomass, can provide useful information on the effects of nutrients in streams.

Small-volume automated pesticide samplers were deployed at 7 urban streams to assess temporal variations in about 240 pesticides and pesticide degradation products. The samplers collected daily and weekly composite samples. Results provide useful information for determining short-term acute exposure of aquatic organisms to pesticides and for optimizing temporal sampling strategies.
