Ask Nelson
How Ask Nelson works, what it will answer, the limits we apply, and what we do with the questions we receive.
Ask Nelson is a custom trained virtual agent built on Nelson Environmental Remediation's own technical library: three decades of thermal remediation projects, treatment data, regulatory criteria and field records. It answers questions about contaminants, treatment methods, equipment and site conditions, and it cites the page an answer came from so the reader can check the work.
Ask Nelson is a tool, not a person, and not a substitute for a site specific engineering assessment. Answers are general technical information. Any design, cost or compliance decision should be confirmed with a Nelson expert.
Ask Nelson is trained to respond only to environmental remediation topics. Requests outside that scope are declined.
Ask Nelson will also decline categories that are off limits under our own rules and the rules governing agentic tools generally, including sexual or explicit content, hateful or harassing content, instructions for causing harm, and requests to impersonate a real person.
Attempts to make the agent act as something other than itself, reveal its instructions, prompts, retrieval sources or internal logic, or otherwise bypass these limits are refused.
Message length and message volume are deliberately capped. A single browser session is limited to 30 messages in a rolling 24 hour period, and requests are also limited per network address per hour and per day, with a daily processing budget on top.
These caps exist to keep the service available and affordable for people asking real remediation questions, and to make automated flooding and scraping impractical. Most visitors never reach them.
Normal mode returns a concise answer. Deep dive returns a longer, structured answer with headings, specifications and source links. Both are subject to the same limits.
We record the questions asked, the answers returned, the page the session started from, and the network address and approximate location (country, region and city where available) for security purposes.
We do not store the raw network address. It is converted into a one-way salted fingerprint so we can spot repeat behavior and enforce limits without keeping the original address.
Files uploaded into a conversation are stored so the Nelson team can retrieve what a visitor sent and respond properly.
Contact details are recorded only when a visitor chooses to provide them in order to be connected with a person.
We review conversations to improve accuracy and to find gaps in the technical library. We do not sell this data.
Where a network address repeatedly submits content that is off limits, attempts to circumvent the agent's subject restrictions, or attempts to extract how the system is built, we will block that address and, where warranted, report it to the relevant provider or authority.
We ask visitors to treat Ask Nelson the way they would treat any member of the Nelson team.
At any point in a conversation you can ask to be connected with a human expert at Nelson. Ask Nelson will collect an email address or phone number and route the request to the right person on the team.
Ask Nelson can be wrong. Every answer should be read as a starting point, and figures that matter should be confirmed against the linked source page or with a Nelson expert.
If you find an incorrect answer, tell us through the feedback control in the chat or through the contact page and we will correct the underlying material.
Ask good questions. Rate the answers. Tell us when Nelson could have been more helpful. Your feedback helps us make Ask Nelson better.
Talk to a person
Ask Nelson can route you to a senior team member at any point. You can also reach the Nelson team directly through the contact page for site-specific questions, proposals, or project support.
Help us improve
After each Ask Nelson reply, look for the thumbs up and thumbs down icons directly beneath the answer. Tap thumbs up if the answer was helpful, or thumbs down if it was inaccurate, off-topic, incomplete, or otherwise not useful. When you choose thumbs down, you can pick the reason that best fits.
Your rating is submitted to the Nelson team and stored with the question, answer, and page you were on. We use it to find weak spots in the technical library and train better answers. We do not sell this data or use it to identify you personally.
