Water chemistry

I'm looking for a Freelancer who specializes in water chemistry analysis and can help me predict alkalinity levels in water. I will provide the water samples to them and they will administer the necessary tests. The timeline should be flexible, as I don't have any strict deadlines that need to be met. Therefore, I'm looking for a Freelancer who has extensive experience and knowledge in this area and can complete this project within a reasonable amount of time. If possible, I would also look for someone who has experience in handling water samples so they can provide accurate and reliable results. Thank you!

I ultimate goal is to create an equation / algorithm to accurately predict alkalinity levels in water based off other data points
