“…This effect has previously been reported for stream water as an effect of terrestrial liming (Hindar et al 2003), and for soil solution after application of both wood ash and dolomite Holmström et al 2003). This increase is usually attributed to a fertilization effect occurring from the treatment that increases the biological activity and hence the turnover time for different carbon compounds in the soil (Nilsson et al 2001;Perkiömäki and Fritze 2002).…”

“…Regardless of treatment, however, all stream waters exhibited a general pattern of declining concentrations of SO 4 , Ca, sum of base cations and increasing acid neutralizing capacity (ANC) probably due to the reduced sulphur deposition. In contrast, Hindar et al (2003) investigated a stream water draining an 84-ha catchment treated with 3 tonnes/ha of dolomite and reported significant increases in pH, Ca. Mg, ANC and TOC and decrease of inorganic monomeric Al over a 6-year period after liming compared to a reference stream.…”

Due to increased whole-tree harvesting in Swedish forestry, concern has been raised that a depletion of nutrients in forest soil will arise. The Swedish Forest Agency recommends compensation fertilization with wood ash to ensure that unwanted effects are avoided in the nutrient balance of the forest soil and in the quality of surface water. In this investigation, the chemistry of two first-order streams, of which one was subjected to a catchment scale treatment with 3 tonnes of self-hardened wood ash/ha in the fall of 2004, was monitored during 2003-2006. Large seasonal variations in stream water chemistry made changes due to ash application difficult to detect, but evaluating the ash treatment effects through comparison of the stream water of the treated catchment with the reference was possible via statistical tools such as randomized intervention analysis in combination with cumulative sum charts. The wood ash application did not yield any significant effect on the pH in the stream water and hence did not affect the bicarbonate system. However, dissolved organic carbon increased, a previously unreported effect of WAA, bringing about an increase of organic anions in the stream water. The wood ash application also induced significant increases for Ca, Mg, K, Si, Cl and malonate, of which K was most prominent. Although significant, the changes induced by the wood ash application were all small compared to the seasonal variations. As a tool to counteract acidification of surface waters, WAA seems to have limited initial effects.

“…Furthermore, the amount of inorganic aluminium decreased significantly in run off water from catchments where both recharge and discharge areas were treated, but have yet not decreased in run off water from catchments where only recharge areas were treated. This is in accordance with several other studies where positive effects on run off water have been reported after lime application on forest soils (Bell, 1992;Clair & Hindar, 2005;Direktoratet for naturforvaltning, 2001;Driscoll et al, 1996;Hindar, Wright, Nilsen, Larssen, & Hogberget, 2003;Larsson & Westling, 1997;Olem, 1991;Traaen et al, 1997;Westling & Hultberg, 1990) and wetlands (Borg, Ek, & Holm, 2001;Gunn, Sein, Keller, & Beckett, 2001).…”

Recovery of Acidified Streams in Forests Treated by Total Catchment Liming

Reduced emissions of acidifying pollutants have changed the acidification process, and as a result, forest soils and surface waters are slowly recovering in Sweden. However, model calculations show that some areas may never recover completely unless further measures, such as liming, are undertaken. Liming of surface waters (lakes, rivers and wetlands) has been successfully practised in Sweden since the 1970s, but repeated treatments are necessary. A full recovery of acidified lakes and streams without frequent liming is however not possible until soil acidification is reversed in the most strongly affected areas. In this study, the recovery of acidified streams was examined using 'the total catchment approach' i.e. treatment of both recharge and discharge areas. The aim was to compare the quantitative effect of different treatments on run off chemistry and the recovery of brown trout. Catchments in southwest Sweden were treated with a combination of 2 tons of wood ash and 4, 6 or 12 tons of crushed limestone per hectare in 1998/1999. Treatment of both recharge and discharge areas resulted in fast and significant changes in stream water quality, e.g. increased concentrations of calcium, higher pH and ANC and a decreased concentration of inorganic aluminium. The initial changes were dependent on the distribution of the applied lime between discharge and recharge areas rather than the average dose on the total catchment. Treatment of recharge areas only, resulted in smaller but still significant effects on calcium, pH and ANC in stream water. Furthermore, there was an initial leaching of nitrate but it was only minor compared with the elevated leaching that occurs after a clear-cut. As a result of the treatments, brown trout is now successfully reproducing.

“…Elevated nutrient concentrations may in turn result in eutrophication and algal blooms (Correll, 1998;Freeman et al, 2009;Hecky and Kilham, 1988;Vollenweider, 1968), which are particularly problematic in drinking water supplies (Smith, 1998). Liming of agricultural land has been associated with increased surface water pH (Hindar et al, 2003). Drainage of wetland habitats in an attempt to improve their economic value has also been linked to elevated colour and DOC concentrations in surface waters (Holden et al, 2004;Wallage et al, 2006).…”

Numerous catchment characteristics including topography, geology, soil and vegetation are reported to exert a strong influence on mean surface water properties. The present study employs a geographical information system (GIS) approach to examine, for the first time, the relationship between reservoir water quality [dissolved organic carbon (DOC) concentration, colour, nitrate concentration and pH] and catchment Phase 1 Habitat coverage. Analysis was conducted on two occasions and at two different spatial scales. Numerous statistically significant correlations were identified, suggesting the use of Phase 1 Habitat data could help improve predictive models of surface water quality. The occurrence and strength of correlations varied seasonally in response, we argue, to temporal variations in hydrological regime and anthropogenic activity. The data also suggest that the proximity of habitat types to the reservoir is significant in affecting reservoir water quality. The findings are used to recommend suitable measures for drinking water companies to mitigate against water quality issues.
