The examples in this study show clearly that the freshwater reservoir effect can seriously corrupt radiocarbon dating at inland sites.
The investigation of organic residues associated with archaeological pottery using modern analytical chemical methods began in the 1970s.

In recent years, with carbon dating providing precise dating methods using AMS (accelerator mass spectroscopy), archaeology has taken a new position by achieving remarkable technological advances in both hardware and software.
By examining over 2000 specimens of excavated carbonized extraneous matter on Jomon Period pottery, and dwellings found mainly in Japan, I have been able to estimate the actual age of Jomon and Yayoi Period pottery, order them chronologically and draw up a timeline.
(Fig.1) With numerous forms of chronological research, the fine, relative sequencing of Jomon pottery, not seen anywhere else on earth, becomes clear and the results of carbon dating reveal no inconsistencies with the pottery timeline.
In a sediment core from the Limfjord, northern Denmark, the impact of the freshwater reservoir effect on radiocarbon dating in an estuarine environment is examined.
Did they live in the archaeological period known as Iron Age I, which is archaeologically poorly documented, or in Iron Age IIa, for which more evidence is available.The aim of this study is to examine the order of magnitude and degree of variability of the freshwater reservoir effect over short and long timescales.Radiocarbon dating of recent water samples, aquatic plants, and animals, shows that age differences of up to 2000 C years can occur within one river.Information about the environment and climate can be extrapolated from the isotopic composition of compounds detected in potsherds, potentially providing novel avenues of investigation.The direct dating of lipids in potsherds is opening up new opportunities for building archaeological chronologies, while the integration of lipid residue analyses with other environmental and cultural proxies within interdisciplinary projects is already providing unprecedented insights into past lifestyles, from site to regional scales.
Singer-Avitz claims the material evidence of archaeological stratigraphy, including pottery finds, should not take second place. A useful tool but only one and not the only when it comes to determining Bible chronology. According to the low chronology, the transition to Iron Age IIa occurred around 920–900 B. However, the differences in data between the various schools are not dramatically far apart. In an attempt to solve this chronological problem and to achieve a more accurate date for the transition period, many scholars have resorted to carbon-14 (or radiocarbon) analysis, which can be performed on any organic substance, like wood or grain.
