“…Based on these findings thresholds are raised and discussed for groundwater discharging into surface waters (Burkart et al, 2004;Lewandowski et al, 2014). So far only a few studies tried to actually quantify groundwater-borne P loads to lakes and rivers and to evaluate the impact on their trophic state (Ala-aho et al, 2013;Jarosiewicz and Witek, 2014;McCobb et al, 2003;Ouyang, 2012;Shaw et al, 1990). However, the quantification of LGD-derived P loads is difficult.…”

Jarosiewicz A., Witek Z. (2016): Is the atmosphere an important source of phosphorus in northern Poland? Soil & Water Res., In this paper we determined the phosphorus (P) concentration in precipitation, and calculated the annual P deposition rate at three study sites located in northern Poland. We observed that the mean annual volume-weighted concentration of mineral phosphorus (P min ) in wet deposition varies from site to site. The estimated annual wet deposition rate of P min in the study region amounted from 0.1 to 0.39 kg/ha. The concentration and deposition rate of P min in the southern part of the study region was significantly lower than that in the northern and central part. We detected that the P min deposition was strongly positively correlated with the fraction of arable land in the study site vicinity, and also positively correlated with the mineral P fertilizer consumption in the area. The mean annual volume-weighted concentration of P min in wet deposition varied from 0.015 mg/l in the area of the lowest arable land percentage and the lowest mineral fertilizer consumption, to 0.046 mg/l in the area where the arable lands comprise 84% of agricultural land, and mineral P fertilizer consumption exceeded 33 kg/ha. In the P soil surface balance the atmospheric wet deposition represents 2.1-5.6% of annual total inputs of total P. The level of atmospheric P input varies widely by catchment and is related to land use (fertilizing, intensity and type of crop production).

“…The importance of groundwater to a lake nutrient budget depends on both the volume of groundwater exchange and the concentration of nutrients associated with that exchange. In some settings where groundwater exfiltration is small from a water‐budget perspective, it can be the largest input term from a nutrient‐budget perspective (LaBaugh et al ., ; Lewandowski et al ., this issue; Jarosiewicz and Witek, ).…”

Abstract:Lake eutrophication is a large and growing problem in many parts of the world, commonly due to anthropogenic sources of nutrients. Improved quantification of nutrient inputs is required to address this problem, including better determination of exchanges between groundwater and lakes. This first of a two-part review provides a brief history of the evolution of the study of groundwater exchange with lakes, followed by a listing of the most commonly used methods for quantifying this exchange. Rates of exchange between lakes and groundwater compiled from the literature are statistically summarized for both exfiltration (flow from groundwater to a lake) and infiltration (flow from a lake to groundwater), including per cent contribution of groundwater to lake-water budgets. Reported rates of exchange between groundwater and lakes span more than five orders of magnitude. Median exfiltration is 0.74 cm/day, and median infiltration is 0.60 cm/day. Exfiltration ranges from near 0% to 94% of input terms in lake-water budgets, and infiltration ranges from near 0% to 91% of loss terms. Median values for exfiltration and infiltration as percentages of input and loss terms of lake-water budgets are 25% and 35%, respectively. Quantification of the groundwater term is somewhat method dependent, indicating that calculating the groundwater component with multiple methods can provide a better understanding of the accuracy of estimates. The importance of exfiltration to a lake budget ranges widely for lakes less than about 100 ha in area but generally decreases with increasing lake area, particularly for lakes that exceed 100 ha in area. No such relation is evident for lakes where infiltration occurs, perhaps because of the smaller sample size.
