E.coli
Charles Farmer, PIXNIO
Summer swims in a lake or river are an important part of Kiwi culture – but to be safe, the presence of E.coli (Escherichia coli) bacteria has to be minimised. These resources aim to reduce farm sources of E.coli and improve its detection.

Assessing the Yield and Load of Contaminants with Stream Order: Would Policy Requiring Livestock to Be Fenced Out of High-Order Streams Decrease Catchment Contaminant Loads?
This paper won the JEQ Best Paper Award 2019. Concentration and flow data for 1998 to 2009 were used to calculate catchment load and yields…
Journal Article
Indirect faecal source tracking methods to elucidate critical sources and contaminant transfers through catchments – a review
In New Zealand, there is substantial potential for microbial contaminants from agricultural fecal sources to be transported into waterways. Understanding contaminant transport pathways from catchment…

Variability of Escherichia coli Concentrations in Rivers during Base-Flow Conditions in NZ
We compared the variability of E. coli concentrations in baseflow of 3 different-sized rivers in both summer and winter at the time scales of minutes,…

Journal Article
gndDb, a Database of Partial gnd Sequences To Assist with Analysis of Escherichia coli Communities Using High-Throughput Sequencing
The use of culture methods to detect Escherichia coli diversity does not provide sufficient resolution to identify strains present at low levels. Here, we target…

The effectiveness of streambank fencing to improve microbial water quality: a review
This literature review collates published data on the effectiveness of fencing stock out of waterways to reduce faecal indicator bacteria concentrations in streams. Eighteen suitable…

A Heuristic Method for Determining Changes of Source Loads to Comply with Water Quality Limits in Catchments
A common land and water management task is to determine where and by how much source loadings need to change to meet water quality limits…
Journal Article
Development of a national-scale framework to characterise transfers of N, P and Escherichia coli from land to water
A hydrological framework encompassing nitrogen (N), phosphorus (P) and microbial (E. coli) transfer from land to water was developed to provide a consistent and rapid…
Journal Article
Mitigation of phosphorus, sediment and Escherichia coli losses in runoff from a dairy farm roadway
Dairy cow deposits on farm roadways are a potential source of contaminants entering streams. Phosphorus (P), suspended sediment (SS) and Escherichia coli (E. coli) loads…
Journal Article
The impact of cattle grazing and treading on soil properties and the transport of phosphorus, sediment and E. coli in surface runoff from grazed pasture
Contaminant loss from grazed pasture can negatively affect freshwater quality. There is, however, little data on the impact of different levels of grazing/treading on contaminant…
Method
Refinement of the Framework for Assessment of Recreational Water Quality
Regional and city council staff now have a documented process to follow when faecal contamination is identified in freshwater, created by ESR researchers involved in…
Technical Report
Faecal source tracking and the identification of naturalised Escherichia coli to assist with establishing water quality and faecal contamination levels
E. coli are routinely measured as faecal indicator bacteria (FIB) to provide indications of microbial water quality in parallel with other physico-chemical parameters. Recent evidence…
