Title

Faecal indicator data from 54 lakes in Greater Glasgow, Cumbria, and Norfolk, UK, 2016-2017

Abstract

This dataset contains information about water quality based on faecal indicators at eighteen lakes in each of three lake districts: - Greater Glasgow conurbation, Scotland - Cumbria, NW England - Norfolk, E England. Lakes were sampled once in each of three seasons (spring, summer and autumn) in either 2016 (Norfolk) or 2017 (Cumbria and Greater Glasgow) with faecal indicators being quantified at three discrete sampling stations in each lake (>50m apart) and at three points at each station (i.e. nine samples per lake per sampling date). Faecal indicators were quantified based on standard dilution, membrane filtration and incubation, followed by colony counting. The data were collected to investigate the fine scale connectivity between Faecal Indicator Organisms (FIO) densities within water bodies and diffuse and point source inputs from the adjacent catchment and from biological vectors. They also provide an indication of the relative sources of variation in reported concentrations that is relevant for environmental regulatory purposes. The work was supported by the Natural Environment Research Council grant NE/N006437/1 (Hydroscape: connectivity x stressor interactions in freshwater habitats).

Lineage

Sub-surface water samples obtained from multiple discrete points within 18 water bodies in each of three lake districts via wading and shore-based sampling. Standard water body characteristics (area, elevation, perimeter etc) are available from the UK Lakes Portal (https://eip.ceh.ac.uk/apps/lakes/). Water samples for microbial analysis were stored at 4 degrees C and processed within six hours of collection. 100ml samples at three dilutions were ﬁltered through 0.45-um membrane ﬁlters, placed onto the surface of Membrane Lactose Glucoronide Agar (MLGA agar). Plates were incubated at 37 degrees C and counted after 24 hours. Counts are reported as number of Colony Forming Units (CFU) per 100 ml water. Data limitations: spatial sampling points within each water body were established with a handheld GPS with typical accuracy of +/- 3-5m. Concentrations of Faecal Indicator Organisms (FIOs), especially in water, are highly spatially and temporally variable over short distances and time scales. The data therefore provide a near instantaneous picture of the spatial variation in FIO concentrations within a water body at a given time. The data are suitable for an assessment of relative sources of variation in FIO concentrations (i.e. within sample location, between sample location, between site, between district and between season). Data were added to an Excel spreadsheet and exported as .csv files for deposit into the EIDC.
