Water Quality in the Moselle Brook
The Moselle Brook is in North London and flows through the Haringey borough as a tributary of the River Lea. Historically in the 19th century, the Moselle Brook faced challenges of pollution and since has been culverted along significant stretches of the river to protect public health. More recently, the Haringey Rivers Forum (HRF) formed, as a subsidiary organization of the Haringey Residents Association and Haringey Friends of Parks Forum, due to a realization that the challenges of the past do not reflect the present. They seek to make Haringey more sustainable with a goal of de-culverting of sections of the Moselle Brook and need to determine the current water quality and adequate policies and standards for urban watercourses that can ultimately be used for communication with the local government and developers. A team of University College London (UCL) MSc Environmental Systems Engineering (ESE) students will work to deliver these needs by providing data on water quality across six sites on the Moselle and suggesting evidence-based recommendations for appropriate policy measures.
This research was supported by the University College London Department of Civil, Environmental, and Geomatic Engineering and MSc Environmental Systems Engineering program. We thank our partner, the Haringey River Forum, and respective volunteers for their diligent collection of water samples bi-weekly across several locations on the Moselle Brook. Additionally, we thank John Miles, President of the Haringey Rivers Forum for his coordination of all volunteers and sampling sites and for his time collecting samples and leading site visits for the team. Finally, we are very grateful for the continued support and guidance of Dr. Lena Ciric in her supervision of this project.

Turbidity Testing
zhlédnutí 51Před 4 lety
This test occurs with the aid of a turbidity meter. Turbidity is caused by small particles that can not be seen by the naked eye, but cause a cloudiness and haziness in the water sample. The original sample is placed in a glass vial and into the machine. The machine shoots an artificial light through the water sample and particles absorb the light. Light not absorbed is recorded on the other si...
pH and Conductivity Testing
zhlédnutí 1,2KPřed 4 lety
This machine helps us test for both pH and Conductivity simultaneously. The probe must be rinsed with DI water (simply purified water) then it can be placed directly into the test tubes with the sample. The rinsing is repeated between each test. pH measures how acidic or basic the water is. Conductivity measures how easily an electric charge or heat can pass through the water sample.
Coliform Testing: Filtering Water Samples through Filter Paper - Part 2
zhlédnutí 26Před 4 lety
The UCL collaborative MSC ESE students are filtering the diluted water samples through the filter paper. This paper can be placed on the petri dish containing agar. After shaking the dishes non-stop for 48 hours in a machine, the coliform colonies will form on the filter paper so the students can count them.

Dilutions for Coliform Testing
zhlédnutí 20Před 4 lety
UCL collaborative project students dilute water samples from the Moselle with DI water. Often the samples are too concentrated and will produce too many coliforms to count at a later stage in the procedure. Therefore, to mitigate this, the students dilute the samples to ensure the coliforms will be more accurately countable.
