Nine Waters (Media: found water and universal indicator)

5 microlitre aliquotes of the pH indicator and water samples were mixed on a hydrophobic surface in order to maintain the integrity of the droplets. Love this one.

The pH indicator was impregnated into paper and 5 microlitres of th water samples pipetted onto it. Don't like this process

In these tests, I continue to explore the nature of water. The chemical properties of pure water are universal, and unchanging, and what gives natural water courses their identity, and influences what else can live in them, exists within water and between the spaces of its polar molecules. I’m seeking to reveal these defining elemental signatures. One of the most important of these is  pH, that is whether the water is acidic or alkaline, and this can be measured by adding a pH indicator to the sample. The colour of the indicator changes according to the pH value of the water. I travelled  86 miles today and collected nine water samples on my journey and experimented on them.

Not unlike Damian Hirst’s spot paintings but the colours that  are generated are predetermined by, and are a direct reflection of the natural world. Oh and there’s acid rain there in the mix too!

Hoping to develop this into a much larger project with the help of a pointillist

From left to right the waters are:

1. Tap Water, Four Marks, Hampshire (pH 9, alkaline)

2. Rainwater, Four Marks, Hampshire (pH 4.5, acidic)

3. Seawater, Broadmarsh, Hampshire (pH 9, alkaline)

4. Marsh water, Tannic Pond, Thursley Common, Surrey (pH 5.5, acidic)

5. Water from the Moat,  Thursley Common, Surrey (pH 4.5, acidic)

6. Marsh water, Raft Spider pool, Thursley Common, Surrey (pH 5.5, acidic)

7. River Itchen water, Ovingdon, Hampshire (pH 9.0, alkaline)

8. River Wey water, Tideford, Surrey (pH 7.5, slightly alkaline)

9. Marsh water,  Bladderwort  pool, Thursley Common, Surrey (pH 4.0, acidic)
