“…Peak concentrations of lead and phosphorus occurred within 10 min after the start of rainfall. Similar peaks at the onset of runoff have been observed in other studies of urban runoff quality (Wilber and Hunter, 1977;Helsel and others, 1979). The second peak on the suspended-solids hydrograph is reduced approximately 300 mg/1 from the first peak although the peak discharge is nearly the same.…”

“…Streams in the piedmont area of North Carolina are particularly susceptible to sediment problems because erodible soils contain a high percentage of clay-sized particles . These smaller particles stay in suspension for long periods of time and may adsorb trace metals (Wilber & Hunter, 1977) . indicated that sediment eroding from clay soil types had a greater affect on stream macroinvertebrates than sediments eroding from sandy soil types .…”

Effects of land use on water quality and aquatic biota of three North Carolina Piedmont streams

1994

Three streams in the Piedmont ecoregion of North Carolina were studied to evaluate the effect of land use (forested, agricultural, urban) on water q uality and aq uatic biota . In comparison with the forested stream, there were few changes in water q uality at the agricultural and urban streams . Suspended-sediment yield was greatest for the urban catchment and least at the forested catchment. Suspended-sediment concentrations during storm events followed this same pattern, but at low-moderate flows suspended-sediment concentrations were greatest at the agricultural site . Most nutrient concentrations were highest at the agricultural site, and the amount of `available' dissolved nitrogen was elevated at both the urban and agricultural sites . High concentrations of metals (totals) in the water column were sometimes observed at all sites, but maximum average concentrations were recorded at the urban site (especially Cr, Cu, and Pb) . Maximum sediment metal concentrations, however, were not found at the urban site, but were usually recorded at the forested site . Only minor differences were noted between fish communities of the forested and agricultural sites, although both abundance and average size of some species increased at the agricultural site . The fish community at the urban site was characterized by low species richness, low biomass, and the absence of intolerant species .Invertebrate taxa richness, a biotic index, and the number of uniq ue invertebrate species (found at only one site) indicated moderate stress (Fair water q uality) at the agricultural site and severe stress (Poor water q uality) at the urban site . At the agricultural site, declines in taxa richness within intolerant groups were partially offset by increases within tolerant groups . The agricultural stream had the highest abundance values, indicating enrichment . The urban site, however, was characterized by low species richness for most groups and very low abundance values . Analysis of seasonal patterns suggested detritus was the most important food source for invertebrates in the forested stream, while periphyton was of greater importance in the agricultural stream . Dominant macroinvertebrate groups shifted from Ephemeroptera at the forested site, to Chironomidae at the agricultural site, and Oligochaeta at the urban site . There was little between-site overlap in dominant species (8-17%), indicating that land use strongly influenced the invertebrate community . Chemical and physical parameters measured at the three sites did not seem sufficient to account for all of the observed differences in the invertebrate communities, suggesting some unmeasured toxicity . Biological measurements, especially macroinvertebrates community structure, consistently indicated strong between-site differences in water and habitat q uality .

“…An increase of some other metals during high water flow and flood was also found in mountain streams (Abesser et al, 2006;Hardie et al, 2007). In such periods, additional sources of metals may be atmospheric precipitation or re-suspension of river sediments, which often act as 'secondary' sources of pollution (Baborowski et al, 2004;Wilber and Hunter, 2007). The contents of Cr and Ni were also dependent on the Biała Tarnowska River flow, indicating diffuse contamination as a dominant source.…”

-We studied the variability of physico-chemical parameters in water, and heavy metal contents in water and sediment over time and along the Carpathian Biała Tarnowska River (southern Poland) and related them to catchment geology, human impact and the effect of barriers as a side aspect. The river water was well oxygenated, had pH 7.7-9.5 and was characterised by low and average flow. Temperature, pH and dissolved oxygen did not change significantly, while the contents of major ions, NO 3 À , NH 4 þ , Mn and Fe increased gradually along the river. The major ion contents were negatively, and nitrate, Mn, and Fe positively, correlated with the flow. We recognise correlations between nitrate, Fe and Mn to be good indicators of soil erosion processes in the catchment. River sediment was unpolluted by most of the studied metals (slightly polluted by Ni and Cd). The differences in the values of some parameters (pH and NH 4 þ , PO 4 3À , HCO 3 À , Mn, Cd and Pb concentrations) in the water, and heavy metals in the sediment upstream and downstream of some of the barriers were determined. Spatiotemporal changes in the values of studied parameters and the results of statistical calculation indicate the impact of human activity in the catchment basin (land use, wastewater) on the water chemistry.Keywords: physico-chemical parameters / heavy metals / small barriers / catchment geology / human impact Résumé -Variabilité chimique de l'eau et des sédiments dans le temps et le long d'une rivière de montagne soumise à des impacts naturels et humains. Nous avons étudié la variabilité des paramètres physico-chimiques dans l'eau et les teneurs en métaux lourds dans l'eau et les sédiments au fil du temps et le long de la rivière des Carpathes Biała Tarnowska (sud de la Pologne) et nous les avons mis en relation avec la géologie du bassin versant, l'impact humain et l'effet des barrages comme aspect secondaire. L'eau de la rivière était bien oxygénée, avait un pH de 7,7 à 9,5 et se caractérisait par un débit faible et moyen. La température, le pH et l'oxygène dissous n'ont pas changé de façon significative, tandis que la teneur en ions majeurs, NO 3 þ , PO 4 3À , HCO 3 À , Mn, Cd et Pb) dans l'eau et les métaux lourds dans les sédiments en amont et en aval de certains barrages ont été déterminées. Les changements spatio-temporels des valeurs des paramètres étudiés et les résultats des calculs statistiques indiquent l'impact de l'activité humaine dans le bassin versant (utilisation des sols, eaux usées) sur la chimie de l'eau.
