The Only Way is Essex's coast

Posted by: , Posted on: - Categories: Cleaner Seas, Fisheries and biodiversity

Walking up and down beaches with sampling gear during a heatwave may not be everyone’s ideal job but I wouldn’t want to be anywhere else.

I am lucky that during the summer, my job consists of sampling the water quality along England’s longest coast – good old Essex!


I have worked for the Environment Agency for 22 years and my current role is an environment officer in the Sampling and Collection team in the East Anglia area. I enjoy it for its varied nature, which changes with the seasons, and the fact that it means I’m outside most of the time.

From May to September, it’s bathing water season so I’m regularly out sampling the water quality at the 10 different beaches in Essex along with my two other colleagues.

The monitoring takes place to provide accurate information to locals and tourists about water quality at our bathing waters and to comply with the Bathing Water Regulations. Up to 20 samples are taken at each site through the season and there are over 400 sites in England that are tested. The bathing water quality results for English beaches in 2018 are available here:



I have to go about knee height into the sea and then fill the sample bottle by throwing it out on a secure line and letting it fill as it sinks. I then put the sample bottle in a fridge in my van where it remains until I get back to the depot and then it is taken by courier for analysis at our laboratory in Devon. The results are then collated and published on the Bathing Water Data Explorer website. The website has received a record number of visits this year.

As well as collecting a sample of sea water, I also note down supporting information, such as the number of bathers and beach users, the salinity of the water, animal faeces, and litter. You do get asked a fair few questions by members of the public, who are interested to know what you are doing and I like to inform them about why we are doing it. Often people aren’t aware that we do this sort of work in the Environment Agency and I think it is good that they are able to see us as a very real presence on the ground.

The work is quite demanding. Walking with sampling gear all day is quite tiring, especially in the heat so you definitely feel like you’ve done a day’s work afterwards. However, it is worth it for the chance of walking along the beautiful Essex coastline, which spans 350 miles.

I don’t just sample bathing waters though. All year round I am out and about in my van collecting samples from rivers, boreholes and discharge points. Nationally we have over 10,000 designated sites in rivers, lakes, groundwaters and transitional and coastal waters as well as trade effluents and private works and this information is freely available to the public on our Open Data webpages. Every month we visit nearly 80 sites to take groundwater dip level readings. During the spring and autumn months I undertake invertebrate surveys in the river and collate supporting information on the aquatic plants present and land usage, among other things. From April to October I’m part of a team helping out with fish population surveys. We use electrofishing to stun and catch fish so that we can measure them and determine their age before returning them to the river. This data is used to monitor the health of the river ecosystem.

I am pleased that the work me and my team do makes a real difference to the environment and it’s an added bonus that I get to do it all in the county that I’m proud to call home.

    I have come across your website whilst doing some work for a few of my clients who operate in the same industry as you.

    I would like to use this as an opportunity to introduce our B2B lead generation services.

    Creative Bear Tech is a B2B lead generation company based in Latvia and has offices in Lithuania, Estonia and the UK. We provide off-the-shelf B2B marketing lists and also do custom business contact detail scraping. If you are relatively computer savvy, we also provide our search engine scraper that you can use to scrape your own B2B marketing lists.

    We mostly work with businesses that operate at a wholesale level by providing them with scraped B2B marketing lists of their target clients. For example, we would provide a jewellery wholesaler with a list of all the jewellery stores in the world so that they could promote and sell their products to all jewellery stores. To put it very simply, we connect the dots between businesses.

    Here are a few links that you may find helpful:
