Have you been wondering about how to water your plants? Has river water been on your list? While most of us use tap water, the thought of using natural river water seems tempting, but it can harm your plants. Although the problems can be small-scale, you shouldn’t ignore them.
River water can be harmful to plants. It may contain chemical and industrial waste material that can hinder the growth of plants.
No matter what type of water you’re using for your plants, it’s essential to keep the pH value in check.
Natural doesn’t necessarily mean pure!
River water can consist of chemical constituents and industrial waste material. This doesn’t just make it a hazard for humans, but it’s dangerous for plants too.
Rivers that flow naturally and are not cleaned by any method are more likely to have such bacteria. Therefore, giving such water to plants can cause death.
Here’s an overview of how industrial waste damages plants:

Industrial waste contributes to diseases
Polluted river water consists of high nitrogen and phosphate chemicals. All these chemicals combine to form all sorts of water-borne diseases and fungi.
River water may disturb the pH value of your soil.
Typically, river water has high levels of salt. High salinity can damage the soil, making it lean toward the alkaline spectrum of the pH scale.
If you do intend to use river water, I would suggest you get this pH level detector for the soil of your plants.
The pH value of water is more likely to disrupt soil texture if it is made of clay. Since river water is groundwater, there will be mineral ions present other than hydrogen and hydroxyl ions. When water has too much hydrogen, it is acidic; if it has too many hydroxyl ions, it is alkaline.
If the texture of the soil is fine, it will resist changes. Otherwise, the pH value of the soil can either become too acidic or too alkaline. Having a high acidic or alkaline value can damage the growth of plants.
Collected Chemicals on the Base of the Soil
If you’re using fertilizers for your plant and you have a river nearby, you need to be more careful. Using a fertilizer can leave some chemicals on the base of the soil. A lot of nitrogen and phosphorus can collect over some time. These levels can become more than needed if the river water is used.
Salty water can hurt your precious plant more than you think!
The salt level in the soil is known as salinity. Soil with high salinity levels can impair the growth of a plant, causing its cell structure to break down.
Not all plants can grow well when exposed to salt. Soil with high salinity levels can disturb the aeration and drainage system. This blockage happens due to the presence of unnecessary sodium.
But here’s the question: How can you be sure that river water damages your plants? Is it possible to detect excessive levels of salt? Well, if your plants have been receiving excessive salt, they’ll be showing you some signs like these:
Based on my personal experience, this salinity checker will be useful for you to check the water before giving it to your plants.
Are you planning to get water from a small river or a big one?
Enzymatic kits are used to detect pesticides in river water. However, the process can be complex for bigger rivers.
Not all rivers are small. The bigger the surface area of the river, the harder it is to detect pests. River water has many pesticides that can take on many shapes.
These pesticides can even turn into other forms of chemicals and substances that can gather in water and make it unsuitable for drinking and irrigation alike in both the small and long run.
Decomposed or not, pesticides in river water don’t just affect plants from the top. If you’re watering infected river water on plants, these pesticides can reach deep down into the ground. So the result can be severe contamination, which is hard to turn around for the better.
The benefits of using river water aren’t that straightforward!
River water can inflict all sorts of suffering on plants. But that’s just one side of the story; there can be a few benefits too. However, even these benefits are limited and depend on the resources in your hand.
If water from the river is recycled, it can be a delight for plants!
Is river water always more harmful than tap water? Not necessarily. Using water straight from the tap may not be a super clean choice either. It may contain high chlorine levels that will be removed using evaporation or filtration; otherwise, your plant may begin to sulk because of chlorinated water and eventually die!
Chlorine is not dangerous all the time!
Are you afraid of chlorine hurting your plant? In reality, low chlorine levelsare good for plants, as they are one of the nutrients.
Filtrating river water isn’t easy, but it’s possible. Here are a few ways using which local river water is usually recycled and filtered by higher authorities:
Reverse Osmosis/ Electrodialysis: This method makes use of a barrier to separate ions and molecules that make up dirty substances in river water.
Nano-filtration: A more modern method to filtrate both surface and groundwater using organic substances.
Chemical oxidation: Uses the process of oxidation to tone down the effects of substances that can contaminate the environment.
But all these methods are usually inaccessible to the public. So how is filtered river water beneficial when it can be quite costly? It’s possible to filter river water if you have the time and resources. The easiest method to filtrate river water on your own is to use a pump, but that can be tricky to use, and not everybody has the expertise to ensure that the water is immaculate.
Always outsourcing water from local companies can cost you a lot!
A local nearby river can be a money-saver if the water can be used and filtered easily.
Using water from your local river is less of a burden on your shoulders. However, that’s only possible when you have filtration methods at your disposal. These could be a pump, heat method, and much more.
Other than that, a river can truly be beneficial if there is no central authority governing it. Also, bear in mind that using the local river water may be illegal. You may require a license in advance or maybe it’s not permissible at all!
Do you live in an industrial area?
For rivers situated in the city or town, the risks of contamination are very high. It is better not to use river water at all if you live in the hustle bustle of an industrial area.
In small amounts, water draining out from home appliances can be beneficial.
Gray river water is the water derived from appliances such as dishwashers and washing machines.
The only way such water can be used as a fertilizer is when it’s in a highly diluted form. If it’s present in a river in little quantities, then it poses no threat to the plants. However, large quantities of gray water are unable to dissolve well in a river with a small surface area.
All in all, river water has more risks compared to benefits. Especially if the river is a big one, it can be hard to sense if it even has any benefits. On the other hand, rivers with smaller surface areas can be equally threatening if there is excessive gray water, sewerage water or industrial waste. Filtered tap water is a much easier choice compared to using river water for watering plants.
