Detection of Potential Shallow Aquifer Using Electrical Resistivity Imaging (ERI) at UTHM Campus, Johor Malaysia

Hydrochemical characteristics of surface water and groundwater at Universiti Tun Hussein Onn Malaysia (UTHM) campus, Johor

“…Besides the result was proofed by [10] explained that UTHM and its surrounding area previously was a muddy and coastal area, and the water containing high calcium and chloride due to ancient water intrusion at quaternary area and effects of karts under the land surface respectively. This fact was also proved by previous study conducted using electrical resistivity method, shown that this area was dominant with clay layer that has resistivity value less than 1 ohm [7]. This explains why the groundwater sample had high values of Na + and Cl -.…”

“…Higher EC values of groundwater were generally observed in the point C. In contrast, the EC and TDS levels of swale, lakes and retention pond samples were lower compared to groundwater, ranging from 111 µs/cm to 225 µs/cm and 56 mg/l to 115 mg/l. The wide variation of EC in groundwater showed that this point was influence by high salt content due to layer of soil that dominant with marine clay layer based on data in resistivity imaging that had been conducted in the study area [7]. The requirement for irrigation purposes for EC according to (INQSM) values are below 6000µs/cm.…”

“…Igneous intrusive rock occurs in an area of Batu Pahat in the west, meanwhile over-consolidated sedimentary in Triassic-Jurassic aged at Ayer Hitam, eastern part of UTHM campus [5]. In this study, borehole had been installed at 3 different points based on data obtained from Electrical Resistivity Imaging (ERI) that shown potential shallow groundwater [7].…”

Mapping of Potential Groundwater Using Electrical Resistivity Imaging (ERI) at Low Land Area of Parit Raja Johor

“…Furthermore, some parts of the region were discovered to have higher chargeability values than the surrounding materials at 86.25 m and 131.25 m from the first electrode. This region chargeability value ranges from 50 to 500 ms, may contain very fine sand or clay, such as shalestone [23]. The region with very low chargeability values was most prominently dispersed at 56.25 m from the first electrode at a depth of 20 m. This region has a chargeability value ranging from 0 to 0.9 ms, indicates the possibility of potential groundwater.…”

“…UTHM is also known as a marine clay-encircled area [22]. The left part of the region has a chargeability value less than 1 ms. [23] discovered that materials with similar chargeability values were alluvium composed of clay, silt, sand, or gravel. Furthermore, some parts of the region were discovered to have higher chargeability values than the surrounding materials at 86.25 m and 131.25 m from the first electrode.…”
