Deep well recharge in a polder area near the river Rhine
Published in Jos H. Peters, Artificial Recharge of Groundwater, 2020
To ensure constant compliance with the Dutch standards for soil protection, an activated carbon filter was installed ahead of the recharge well in Nieuwegein as a precautionary measure. This was needed in Nieuwegein where polluted river Rhine is pretreated.

The average content of Ba in soil from the investigated area is 310 mg/kg, with a minimum value of 49 mg/kg and a maximum determined content of 2000 mg/kg. The median value for the content of Ba in soil is 300 mg/kg. The highest content of Ba was found in the soil collected from the north-eastern part of the investigated area. Also, high content of Ba was found in soil samples collected from other small areas in the south-east, east and in the north-west. According to the geological formations, a higher Ba content was found in the soil from the Quaternary swamp sediments, Quaternary floodplain, Quaternary old and young terraces and Pliocene and Miocene sediments (Table 5). The average content of Ba, according to the geological formations, ranges from 180 to 540 mg/kg, with the highest average content in soil from Quaternary swamp sediments (540 mg/kg) and the lowest content in soil from Pliocene sediments (180 mg/kg; Table 5). According to land use, the average content of Ba ranges from 230 to 310 mg/kg. A higher average content of Ba was found in soils from the industrial areas (310 mg/kg) and the lowest average content was found in soils from the forest areas (230 mg/kg; Table 6). If the obtained data for the content of Ba in soil from the investigated area are compared with Dutch standards it is seen that the content of Ba in soil from Skopje is higher that the optimal value (200 mg/kg) but lower that the action value (625 mg/kg). Higher content of Ba in soil from Skopje is a result of its specific lithological origin (таble 5).

Therefore, the obtained data were compared with those of Dutch Standards.[46] The target and intervention values are given in Table 4. It can be seen that the median values for all elements, besides Ba, are below the target values. Barium content is much higher than the target value of Dutch standards because barium is naturally present in Macedonian soil due to the specific geological formations in this region.[43] However, in some specific parts of the Bitola region, could be found quite a high content of some trace elements even higher than the intervention value.

The Pb content in 8 soil samples from the 19 studied gardens (No. 8, 9, 10, 11, 14, 15, 16, and 19) (Table 1, Fig. 3), is higher than the target value (85 mg/kg) and the action value (530 mg/kg) according to the Dutch standards, with the highest Pb content Pb detected in the soil sample from the municipality with number 15, near the village Ularci, before the confluence of the river Zletovska with the river Bregalnica being 478 mg/kg, which is 5.6 times higher than the target value. The mean value for the Pb content was 145 mg/kg and the median was 65.2 mg/kg.
