Why rivers need hands-on help

Rivers are remarkably good at gathering litter. Anything dropped on a street, blown out of an overflowing bin or washed into a drain can end up in a beck, then a brook, then a main river, and eventually the sea. Along the way it snags on branches, sinks into reed beds and piles up behind weirs, where swans, otters, fish and water voles can mistake it for food or become tangled in it. A few hours with a litter picker and a bag genuinely changes a stretch of water, and you can see the difference immediately. It is also one of the most pleasant ways to spend a morning outdoors, but rivers are cold, fast and changeable, so a little preparation makes the day safer and far more productive.

Before you set off

Turn up dressed for the water, not for a stroll. Even on a warm day, banks are damp, muddy and often colder than the surrounding streets.

• Gloves are essential — ideally a cut-resistant pair for picking, with a thinner pair underneath if you prefer dexterity. Disposable gloves alone tear too easily.
• Footwear means wellington boots or sturdy old trainers with grip. Flip-flops, sandals and smart shoes are a recipe for a twisted ankle.
• A buoyancy aid if you will be anywhere near deep water, working from a boat, or standing on a steep or slippery bank. This is not overkill; it is the single most useful piece of kit you can wear.
• Litter pickers, heavy-duty bags, a first aid kit, hand sanitiser and drinking water. A grabber saves your back and keeps your hands away from anything unpleasant.
• Check the river level and the weather before leaving. After heavy rain, flows are stronger, banks are slick and litter that was reachable yesterday may be in the middle of the channel today.
• Check the tide times on tidal stretches. Estuary mudflats and lower reaches can flood quickly and cut off a path you walked in on.
• Tell someone your route and your return time, and go with others where you can. Organised picks run by local river groups, angling clubs and councils bring insurance, spare equipment and a plan.

Staying safe on the bank

Almost all river litter picking should be done from the bank, and that is where you should stay unless you are trained and equipped for anything else.

• Never wade in to reach an item. No bottle, football or traffic cone is worth it. If it is in the water, leave it or use a long pole from a stable position.
• Keep back from the edge. Riverbanks undercut, crumble and collapse, especially where cattle have poached the ground or where vegetation has died back.
• Work in pairs, with one person watching the water and the footing while the other picks. On a group pick, keep a headcount and agree a meeting point.
• Be wary of weirs, sluices, locks and outfalls. Water below a weir is recirculating and can hold a person under. The calm-looking surface above a weir is often the most dangerous place of all.
• Watch for mud. Silt and estuary mud can be deeper than it looks, and it grips boots firmly.
• Stay off icy banks in winter. A slip into cold water triggers cold water shock within seconds, which is a medical emergency even for strong swimmers.

Sorting your haul

Sorting as you go makes the whole operation quicker and means far more of what you collect is actually recycled rather than sent to landfill.

• Recyclable plastics: drinks bottles, milk bottles, detergent bottles and other rigid plastic containers. Keep them separate from the rest and, where practical, empty them of water so the bag does not become unmanageably heavy.
• Metals: drinks cans, food tins and foil trays are almost always worth keeping separate.
• Glass: bottles and jars can be recycled, but bag them separately in something robust so nobody is cut when the bag is handled.
• General waste: crisp packets, wet wipes, sanitary items, polystyrene, plastic bags and anything food-contaminated.
• Do not mix glass or sharps with plastics. One broken bottle can contaminate an entire bag of recycling and it will be rejected.

If a bag is more than you can comfortably carry, stop filling it. Two half-full bags you can lift are better than one you have to drag along a towpath.

Recording unusual finds

It is worth keeping a simple note of anything out of the ordinary: what you found, roughly how many, where, and on what date. A photograph helps. This information is genuinely useful to the people who manage the waterway and can reveal patterns, such as a spot where fly-tipping keeps recurring or a drain that is discharging the wrong thing.

• Bulky or odd items: shopping trolleys, bicycles, e-scooters, car tyres, oil drums and gas canisters usually need a proper removal operation rather than a volunteer with a bag.
• Batteries and electricals should never go in general waste and need separate handling.
• Signs of pollution: discoloured water, an oily sheen, a chemical smell, foam below an outfall or a sudden cluster of dead fish. Note it, photograph it and report it promptly to the relevant environmental regulator or your local council.
• Wildlife concerns: an injured bird, an entangled swan or a stranded fish should be reported to a wildlife rescue or the relevant authority rather than handled yourself.

Hazards, hygiene and heading home

Riverbanks and towpaths are home to a specific set of hazards. Sharps and needles are the ones people worry about most, and the rule is simple: do not pick them up with your hands. Use a litter picker, place them in a rigid container such as a sealed plastic tub or a sharps box if one is provided, and tell the group organiser or your council. Broken glass, rusty metal and fishing hooks with line attached are all common along popular stretches, so treat every unseen item as though it could cut you.

Animal remains — a dead fish, a bird, a small mammal — should be left alone and reported. So should anything that looks like medical waste.

Hygiene matters more than most people expect. Rat urine in river water can carry leptospirosis, a rare but serious infection, so cover any cuts with a waterproof plaster before you start, avoid touching your face, and wash or sanitise your hands thoroughly before eating or drinking. A hot drink afterwards is a fine reward, but not until your hands are clean. If you develop flu-like symptoms, a fever, headache or muscle aches within a few weeks of a pick, mention to your GP that you have been working around river water.

Finally, check yourself over at the end of the day. Ticks are increasingly common in riverside vegetation, so a quick check of arms, legs and hair is worthwhile, and any bites or scratches should be cleaned and watched. Then get warm, dry off, and log what you collected. Count your bags, weigh them if you can, share the totals with your group, and you will have a real number to show for a morning well spent.
