ClearSampling and identification of microplastics in groundwater
Researchers presented a comprehensive protocol for sampling microplastics from groundwater boreholes, including a purpose-built filtration system and detailed laboratory procedures using ATR-FTIR spectroscopy to characterize particles by size, shape, color, and polymer type. This record is a duplicate entry for the same groundwater microplastics sampling and identification methodology as paper 5527.
Microplastics in different water samples (seawater, freshwater, and wastewater): Methodology approach for characterization using micro-FTIR spectroscopy
Researchers developed a standardized methodology for detecting and characterizing small microplastics (10-500 micrometers) in different water types using micro-FTIR spectroscopy. The study tested various sample preparation approaches for seawater, freshwater, and wastewater, establishing reliable protocols for rinsing, digestion, and microplastic collection that can be used to assess treatment plant removal efficiency.

Assessment of Groundwater Contamination by Microplastic Particles: A Case Study in Selected Areas of Mosul District, Iraq
A study of twelve groundwater wells across urban and rural areas of Mosul, Iraq, found microplastic contamination in all samples, ranging from 18 to 103 particles per liter. Most particles were small (under 1 mm), with fibers and fragments both present, and polymer types including polyethylene and polypropylene identified by infrared spectroscopy. Groundwater is a primary drinking water source for millions of people in arid regions, and finding widespread microplastic contamination at these levels underscores the need for water treatment systems capable of removing plastic particles before consumption.
Microplastics in groundwater: a global analysis
Researchers conducted a global groundwater sampling study — collecting approximately 300 litres per site from caves, boreholes, monitoring wells, and surface springs worldwide using a standardised filtration protocol — to characterise microplastic contamination in these poorly studied anoxic systems. The study presented first results aimed at closing a major knowledge gap about microplastic transport and fate in global groundwater resources.
Development and validation of a low-cost modular in-line filtration apparatus for high-volume microplastic sampling in groundwater wells
Researchers designed a low-cost (~$120) all-metal filtration system to collect microplastics from groundwater wells, capable of filtering over 500 liters per well with up to 96% particle recovery. The device addresses a major gap in monitoring — most microplastic sampling tools are too expensive or plastic-contaminated to work reliably in groundwater.
Assessing microplastic (>25μm) presence in groundwater systems in England
This study — the first to systematically assess microplastics in groundwater across England — found microplastic particles present in aquifer samples and developed a standardized sampling protocol comparing different aquifer types and borehole environments. Groundwater contamination is particularly concerning because it serves as a major drinking water source, and this work lays the groundwork for national-level monitoring and regulation.

Distribution and transport of microplastics in groundwater (Shiraz aquifer, southwest Iran)
Researchers investigated microplastic contamination in groundwater from an alluvial aquifer in a semi-arid region of Iran. They identified microplastics in all sampled wells, with fibers and fragments being the most common shapes and polyethylene the dominant polymer type. The study demonstrates that groundwater, an important source of drinking water, is not immune to microplastic contamination and calls for more research on transport mechanisms in subsurface environments.

Tracking microplastics at the source: a comparative study of fluorescent and FTIR microscopy at a drinking water intake in the Perak River, Malaysia
Researchers measured microplastic contamination at a drinking water intake point on the Perak River in Malaysia, finding 12 different polymer types with most particles smaller than 10 micrometers. The study compared two detection methods and found that specialized infrared microscopy was more accurate at identifying microplastic types than fluorescence microscopy. Since this river water goes directly to a treatment plant for drinking water, the findings highlight the need to understand and filter out microplastics before they reach the tap.
