Your Water Shapes
Your Garden
From soil pH to food safety — your irrigation water affects everything you grow. Test it before your plants (and your family) pay the price.
Why Test Your Garden Water?
Your plants can't tell you what's wrong with their water — but the symptoms show up in stunted growth, yellowing leaves, poor yields, and contaminated produce.
Soil pH Disruption
Alkaline or acidic irrigation water shifts soil pH over time, locking out essential nutrients and stunting plant growth even in nutrient-rich soil.
Salt/Sodium Buildup
Sodium in irrigation water accumulates in soil, destroying structure, reducing drainage, and creating toxic conditions for roots.
Chlorine Plant Damage
Municipal chlorine levels that are safe for humans can burn plant roots, kill soil biology, and reduce yields by 20–40%.
Food Safety
Heavy metals and PFAS in irrigation water bioaccumulate in edible crops — your home-grown food could be more contaminated than store-bought.
Key Contaminants for Garden Water
Understanding how each contaminant affects your soil, plants, and produce is essential for productive, safe gardening.
Chlorine & Chloramine
Municipal water contains 0.5–4 ppm chlorine. Most plants show toxicity symptoms at just 0.5 ppm, including leaf tip burn, yellowing, and stunted root development.
Sodium & Salinity (SAR)
High sodium levels destroy soil structure by dispersing clay particles, creating compacted, waterlogged conditions. The Sodium Absorption Ratio (SAR) measures this risk — values above 9 are problematic for most crops.
Heavy Metals
Lead, cadmium, arsenic, and mercury accumulate in soil and are absorbed by plant roots — concentrating in edible portions of fruits and vegetables. This bioaccumulation means even low water concentrations become dangerous over time.
Boron Toxicity
Boron is essential in trace amounts but toxic above 1 ppm for sensitive crops. Many water sources contain 0.5–5 ppm boron. Citrus, stone fruits, and beans are especially sensitive, showing leaf burn at levels safe for other plants.
pH Imbalance
Water pH directly affects soil pH over time. Most plants thrive in pH 6.0–7.0. Water outside this range causes nutrient lockout — iron, manganese, and phosphorus become unavailable even when present in soil.
Bicarbonates & Hardness
High bicarbonate water (>120 ppm) raises soil pH over time and causes calcium carbonate deposits that clog drip irrigation emitters. Hard water also leaves white mineral deposits on leaves during overhead watering.
Crop Sensitivity to Water Contaminants
Different plants tolerate different water quality levels. Use this guide to understand your crops' vulnerability.
| Sensitivity | Common Crops | Max Chlorine | Max Boron | Max Salinity |
|---|---|---|---|---|
| Very Sensitive | Strawberries, Citrus, Avocado, Beans, Onions | < 0.5 ppm | < 0.5 ppm | < 500 TDS |
| Sensitive | Tomatoes, Peppers, Lettuce, Carrots, Grapes | < 1.0 ppm | < 1.0 ppm | < 1000 TDS |
| Moderate | Corn, Wheat, Cucumbers, Squash, Roses | < 2.0 ppm | < 2.0 ppm | < 2000 TDS |
| Tolerant | Bermuda Grass, Beets, Asparagus, Date Palms | < 4.0 ppm | < 4.0 ppm | < 4000 TDS |
Sodium Absorption Ratio (SAR) Guide
Growing Food with Contaminated Water
Your home garden produce isn't tested by the FDA. If your irrigation water contains contaminants, your food could too.
Bioaccumulation in Produce
Heavy metals in irrigation water accumulate in soil and concentrate in plant tissues. Leafy greens absorb the most lead; root vegetables concentrate cadmium; rice absorbs arsenic at rates 10x higher than other grains.
Pathogen Transfer
Bacteria like E. coli and Salmonella from contaminated water can survive on produce surfaces for weeks. Overhead irrigation of edible crops with untested water is a leading cause of foodborne illness from home gardens.
Chemical Residue on Food
Pesticides, herbicides, and industrial chemicals in irrigation water are absorbed through roots and deposited on leaves. Unlike store-bought produce, home-grown food isn't tested — making water testing your only safeguard.
PFAS in Garden Soil
PFAS 'forever chemicals' from contaminated water persist indefinitely in soil. Studies show PFAS transfers from soil to edible crops, particularly leafy greens and root vegetables, at concerning levels.
