Free · Proposal second opinion
Holding a proposal for your lake or pond? Get a scientist's second opinion.
Upload the proposal or quote from your lake or pond company. A WaterDx scientist reads it and follows up by email or phone with what holds up, what's missing, and what to ask before you sign. It's free.
What we check
Does it diagnose before it treats?
A good proposal says what is feeding the algae and shows the data behind it. A service menu with a monthly price is not a diagnosis.
Does it target the real source?
Green water can come from runoff, from phosphorus leaking out of the bottom, or from water that barely moves. Each needs a different fix. We check that the plan matches the likely cause.
Are the dose and the cost sensible?
We look at what is being applied, how much and how often, and what it adds up to over three to five years, with one-time and recurring costs split out.
How will you know it worked?
A baseline before work starts, follow-up measurements on a schedule, and a goal written as a number with a date. Without those, nobody can tell whether the money worked.
You don't have to change vendors
Often the plan you have is close, and a few changes in scope make it match the cause. WaterDx guides you through working with your vendor: what to ask for, when, and how to check that it worked. We take no referral fees.
Your file is stored privately and read only by our scientists. We never share it, including with the company that wrote it.
