No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/wqp_results_near_point for the schema, then POST the same URL with its arguments for the data.

Water-quality sample results within a radius of a latitude/longitude — the “is the water near me tested, and what did it say” tool. Returns measured values with their station, date and unit. Sourced from the USGS/EPA Water Quality Portal.

Parameters

Name	Type	Required	Description
`latitude`	number	yes	Decimal degrees, WGS84
`longitude`	number	yes	Decimal degrees, WGS84 (negative in the US)
`within_miles`	number	no	Search radius in miles (default 10)
`characteristicName`	string	no	Analyte name, e.g. “pH”, “Nitrate”, “Lead”. Strongly recommended — an unfiltered radius query is very large.
`startDate`	string	no	Earliest sample date, YYYY-MM-DD
`endDate`	string	no	Latest sample date, YYYY-MM-DD
`limit`	number	no	Max results to return (default 100, max 1000)
